A new paper has just appeared

Nicola Scafetta 2011: A shared frequency set between the historical mid-latitude aurora records and the global surface temperature. Journal of Atmospheric and Solar-Terrestrial Physics In Press doi:10.1016/j.jastp.2011.10.013

This paper is certainly going to enlarge the debate on the role of natural climate variability and long term change.

The abstract reads [highlight added]

Herein we show that the historical records of mid-latitude auroras from 1700 to 1966 present oscillations with periods of about 9, 10–11, 20–21, 30 and 60 years. The same frequencies are found in proxy and instrumental global surface temperature records since 1650 and 1850, respectively, and in several planetary and solar records. We argue that the aurora records reveal a physical link between climate change and astronomical oscillations. Likely in addition to a Soli-Lunar tidal effect, there exists a planetary modulation of the heliosphere, of the cosmic ray flux reaching the Earth and/or of the electric properties of the ionosphere. The latter, in turn, has the potentiality of modulating the global cloud cover that ultimately drives the climate oscillations through albedo oscillations. In particular, a quasi-60-year large cycle is quite evident since 1650 in all climate and astronomical records herein studied, which also include a historical record of meteorite fall in China from 619 to 1943. These findings support the thesis that climate oscillations have an astronomical origin. We show that a harmonic constituent model based on the major astronomical frequencies revealed in the aurora records and deduced from the natural gravitational oscillations of the solar system is able to forecast with a reasonable accuracy the decadal and multidecadal temperature oscillations from 1950 to 2010 using the temperature data before 1950, and vice versa. The existence of a natural 60-year cyclical modulation of the global surface temperature induced by astronomical mechanisms, by alone, would imply that at least 60–70% of the warming observed since 1970 has been naturally induced. Moreover, the climate may stay approximately stable during the next decades because the 60-year cycle has entered in its cooling phase.

The highlights listed in the announcement of the paper read

► The paper highlights that global climate and aurora records present a common set of frequencies. ► These frequencies can be used to reconstruct climate oscillations within the time scale of 9–100 years. ► An empirical model based on these cycles can reconstruct and forecast climate oscillations. ► Cyclical astronomical physical phenomena regulate climate change through the electrification of the upper atmosphere. ► Climate cycles have an astronomical origin and are regulated by cloud cover oscillations.

========================================================

Dr. Scafetta writes in and attaches the full paper in email to me (Anthony) this week saying:

I can forecast climate with a good proximity. See figure 11. In this new paper the physical link between astronomical oscillations and climate is further confirmed.

What the paper does is to show that the mid-latitude aurora records present the same oscillations of the climate system and of well-identified astronomical cycles. Thus, the origin of the climatic oscillations is astronomical what ever the mechanisms might be.

In the paper I argue that the record of this kind of aurora can be considered a proxy for the electric properties of the atmosphere which then influence the cloud cover and the albedo and, consequently, causes similar cycles in the surface temperature.

Note that aurora may form at middle latitude or if the magnetosphere is weak, so it is not able to efficiently deviate the solar wind, or if the solar explosions (solar flare etc) are particularly energetic, so they break in by force.

During the solar cycle maxima the magnetosphere gets stronger so the aurora should be pushed toward the poles. However, during the solar maxima a lot of solar flares and highly energetic solar explosions occurs. As a consequence you see an increased number of mid-latitude auroras despite the fact that the magnetosphere is stronger and should push them toward the poles.

On the contrary, when the magnetosphere gets weaker on a multidecadal scale, the mid-latitude aurora forms more likely, and you may see some mid-latitude auroras even during the solar minima as Figure 2 shows.

In the paper I argue that what changes the climate is not the auroras per se but the strength of the magnetosphere that regulates the cosmic ray incoming flux which regulate the clouds.

The strength of the magnetosphere is regulated by the sun (whose activity changes in synchrony with the planets), but perhaps the strength of the Earth’s magnetosphere is also regulated directly by the gravitational/magnetic forces of Jupiter and Saturn and the other planets whose gravitational/magnetic tides may stretch or compress the Earth’s magnetosphere in some way making it easier or more difficult for the Earth’s magnetosphere to deviate the cosmic ray.

So, when Jupiter and Saturn get closer to the Sun, they may do the following things: 1) may make the sun more active; 2) the more active sun makes the magnetosphere stronger; 3) Jupiter and Saturn contribute with their magnetic fiend to make stronger the magnetic field of the inner part of the solar system; 4) the Earth’ magnetosphere is made stronger and larger by both the increased solar activity and the gravitational and magnetic stretching of it caused by the Jupiter and Saturn. Consequently less cosmic ray arrive on the Earth and less cloud form and there is an heating of the climate.

However, explaining in details the above mechanisms is not the topic of the paper which is limited to prove that such kind of mechanisms exist because revealed by the auroras’s behavior.

The good news is that even if we do not know the physical nature of these mechanisms, climate may be in part forecast in the same way as the tides are currently forecast by using geometrical astronomical considerations as I show in Figure 11.

The above point is very important. When trying to predict the tides people were arguing that there was the need to solve the Newtonian Equation of the tides and the other physical equations of fluid-dynamics etc. Of course, nobody was able to do that because of the enormous numerical and theoretical difficulty. Today nobody dreams to use GCMs to predict accurately the tides. To overcome the issue Lord Kelvin argued that it is useless to use the Newtonian mechanics or whatever other physical law to solve the problem. What was important was only to know that a link in some way existed, even if not understood in details. On the basis of this, Lord Kelvin proposed an harmonic constituent model for tidal prediction based on astronomical cycles. And Kelvin method is currently the only method that works for predicting the tides. Look here:

http://en.wikipedia.org/wiki/Tide-predicting_machine

Figure 11 is important because it shows for the first time that climate can be forecast based on astronomical harmonics with a good accuracy. I use a methodology similar to Kelvin’s one and calibrate the model from 1850 to 1950 and I show that the model predicts the climate oscillations from 1950 to 2010, and I show also that the vice-versa is possible.

Of course the proposed harmonic model may be greatly improved with additional harmonics. In comparison the ocean tides are predicted with 35-40 harmonics.

But this does not change the results of the paper that is: 1) a clearer evidence that a physical link between the oscillations of the solar system and the climate exists, as revealed by the auroras’ behavior; 2) this finding justifies the harmonic modeling and forecast of the climate based on astronomical cycles associated to the Sun, the Moon and the Planets.

So, it is also important to understand Kelvin’s argument to fully understand my paper.

This work is the natural continuation of my previous work on the topic.

oscillations and its implications. Journal of Atmospheric and Solar-Terrestrial Physics Volume 72, Issue 13, August 2010, Pages 951-970

Abstract

We investigate whether or not the decadal and multi-decadal climate

oscillations have an astronomical origin. Several global surface temperature

records since 1850 and records deduced from the orbits of the planets

present very similar power spectra. Eleven frequencies with period between 5

and 100 years closely correspond in the two records. Among them, large

climate oscillations with peak-to-trough amplitude of about 0.1 and 0.25°C,

and periods of about 20 and 60 years, respectively, are synchronized to the

orbital periods of Jupiter and Saturn. Schwabe and Hale solar cycles are

also visible in the temperature records. A 9.1-year cycle is synchronized to

the Moon’s orbital cycles. A phenomenological model based on these

astronomical cycles can be used to well reconstruct the temperature

oscillations since 1850 and to make partial forecasts for the 21st century.

It is found that at least 60% of the global warming observed since 1970 has

been induced by the combined effect of the above natural climate

oscillations. The partial forecast indicates that climate may stabilize or

cool until 2030–2040. Possible physical mechanisms are qualitatively

discussed with an emphasis on the phenomenon of collective synchronization

of coupled oscillators.

=======================================================

The claims here are pretty bold, and I’ll be frank and say I can’t tell the difference between this and some of the cycl0-mania calculation papers that have been sent to me over the last few years. OTOH, Basil Copeland and I looked at some of the effects of luni-solar on global temperature previously here at WUWT.

While the hindcast seems impressive, a real test would be a series of repeated and proven short-term future forecasts. Time will tell.

Two things I noticed in those graphs.
1) There was a diversion at the start of both graphs. What is the explanation for this? I’m guessing data quality is probably the cause, but it would be nice to know what the author thinks.
2) I don’t see any diversion due to volcanic eruptions. Does that mean that there’s a link between Aurora Borealis and major volcanic eruptions, too?

Aren’t there statistical methods that can determine correlation? It would be good to see those.
@jimmi_the_dalek: The mechanism the paper examines is Cosmic rays cause cloud formation. The interaction between cosmic rays and the magnetosphere is what is being proposed. Isn’t that a physical mechanism?

Is it even remotely possible that both the 60 year auroral cycle and the 60 yr climate cycle are actually more like six of the normal solar sunspot cycles, or three times the normal solar full magnetic cycle.
In which case the auroras may have nothing whatever to do with the climate. Could it be that when the fall cold Temperatures set in, and the ancients spent more time in the sack to keep warm; that naturally lead to a spate of new births the following June.

November 10, 2011 2:14 pm

Since there is no obvious 60 year cycle periodicity in 300 years of sunspot records, I think Scafetta’s efforts are missing the target.

I have to disagree with jimmi_the_dalek.
Wegener inferred the essence of continental drift from the coastline matches across the Atlantic, fossil evidence, and such. He was ridiculed by the geology establishment because neither Wegener nor anyone else could conceive of a mechanism. Once the evidence for sea-floor spreading grew in the late 20th century, the mechanism of mantle flow became more believeable and now Wegener’s idea is confirmed and generally accepted.
Luis and Walter Alvarez proposed extraterrestrial impact to explain the K-T extinction event based on anomalous iridium. They were dismissed by the geology establishment too – until the evidence became too great to ignore.
The beginning of a good hypothesis is the recognition of patterns and anomalies – which leads to thoughts of mechanisms – which leads to testing against real-world data.
BTW, Scafetta is proposing a mechanism – solar variance leads to variable cosmic ray flux, which leads to changes in cloud cover (as with Svensmark), which leads to climate variation.

Surely not true.
Surely it only needs thorough observation and discovery of correlation, to qualify as science. Of course we all ardently desire to “explain” the mechanism but to me that’s the magic and grace of Science, not its minimum requirement, when a “eureka” hypothesis does appear, that encapsulates the observed patterns in a formula, verifiable explanation, or law.

For once, something other than carbon dioxide is causing “climate change”. I admit I cringed at the notion of planetary cyclicity…!

“The partial forecast indicates that climate may stabilize or cool until 2030–2040.”
I believe this same time frame was mentioned in a recent Russian paper I believe I read about here at WUWT. The author then didn’t identify any correlation with other phenomena, but was very certain about cooling until 2030 or so.

why there were so many reports of the aurora borealis being visible from the south of England that I noted in the historic accounts of 1550 to 1650

My guess is that the skies of the South of England were much darker at night in 1550-1650 than they are today. Aurorae that might have been visible then may be completely invisible now. Also, London is at about the same latitude (51degN) as Winnipeg, Canada (49 degN). Winnipeg sees aurorae rather often.

Never mind that this comment has been shredded for what it is, mindguard trolling by the warmies. The statement is not true in any event. Lots of unexplained things were measured before they were understood. To assert that science cannot advance unless it knows where it is going is ridiculous.

The paper is not about cosmic rays influences on cloud formation. It is postulating that the gravitational and/or magnetic field of Jupiter and Saturn can influence the activity of the sun. However, to quote from the paper (yes I have read it),
A full theory that would physically explain how the solar wobbling or the planetary tides may influence solar activity has not been developed yet. However, preliminary studies suggest that planetary gravity may increase nuclear rate ( [Grandpierre, 1996] and [Wolff and Patrone, 2010] ) by favoring the movement of fresh fuel into the solar core. The proposed mechanisms would likely produce the major frequencies herein discussed because it is based on the study of the wobbling of Sun around the solar system barycenter as done in Scafetta (2010b).
As I said at the beginning – astrology – the magnitude of gravitational forces from Jupiter on the sun is way, way too small to have such as effect.

Mark ro, Geoff Sharp-
It implausible that the magnetic fields of Jupiter or Saturn could affect the magnetic fields in the inner solar system, since the solar wind is supersonic- no disturbance created at 5 or 10 AU can propagate back toward the sun any further than the bow shock at each planet.

Having matched the available data to the cycles and hindcast it to show compelling harmonics, and then used it to predict the future, you have to admire the symmetry, logic and hopefully the truth of a reasonable hypothesis. Time will tell.
At least this adds to the conversation on climate variation mechanisms based on observing data rather than clinging to the CO2 mantra. Unfortunately, it is a “model”.

The position of the magnetic north pole explains that latter point. The aurora manifest in a circle around the magnetic pole, which is somewhat closer to Winnipeg than London, leaving us Europeans relatively bereft when it comes to viewing them. If aurora were visible in London in late 14th century they they must have been incredibly powerful.

To those who claim I have not read the paper – I have read more of it than the people who think it is about cosmic rays. Also, the relation to astrology is simple – science has to be quantitative not just handwaving. Do you realise for example that the magnitude of the gravitational field of Saturn on the Sun is less than the effect of the gravitational field of Earth on the Sun? Jupiter is larger but its mass is 1/1000 of the sun’s and it is 800 million kilometers away from the Sun – you work out what the gravitational forces are. Jupiter has a strong magnetic field it is true, being roughly 10 time stronger than Earth’s , but since Jupiter is 5 times as far from the Sun, roughly, the effect of Jupiter’s magnetic field on the Sun, is less than that of Earth’s on the Sun. And I am not claiming that correlations should not be investigated, and am stating that a proposed mechanism for a correlation has to be physically possible.
And for those who reckon I am a troll, or a “warmist” – I am neither – but I realise than skepticism has to work in both directions – and this paper is BS.

I have not claimed that the IPCC science is sound, and I do not have to demonstrate that it is (which I could not do anyway) in order to state that someone who says the motions of Jupiter affect the climate here must be waffling. By all means look for 60 year cycles, but when you find them postulate a physically possible cause.

November 10, 2011 4:17 pm

Magnetic influence from (say) Jupiter may not have to propagate back to Earth to influence climate. If cosmic rays are not isotropic, there will be times when Jupiter’s magnetosphere blocks more cosmic rays than usual before they can get to Earth. But that’s something I’ve never studied — take it as you will.

November 10, 2011 4:25 pm

I remember a while back an explanation for the Dalton and Maunder minimums, that predicted a quiet sun period for the next several decades. Basically, the mechanism was, I believe, planets orbits, like here, and that certain orbits coincided with periods of reduced solar activity, that it showed the most reduced activity during the Maunder, a bit less for the Dalton (both verified by history), and the prediction of another minimum right about now till about 2030 or so slightly less extreme than the Dalton (which was less extreme than the Maunder). Basically, a sort of mini little ice age, significantly colder than the 70’s ice age scare, but probably a little warmer than the Dalton. Since solar cycles go in two’s, this would mean this solar cycle is reduced (it is), and the next one would be much quieter than this one.
One thing I notice here, people tend to come up with their pet theory, which is the theory that explains the whole climate. Idea, what if more than one thing effects climate? What if, for instance, planetary orbits can both effect our magnetosphere and the suns activity? Thus changes in our magnetosphere could let in more cosmic rays, and if that coincides with a period of quiet sun where the reduced solar wind also lets in more cosmic rays, the effect could be greater. Throw in a major volcanic eruption (such as happened during both the Dark Ages and Little Ice Age cooling periods) for a “year without summer”, and perhaps coincide with cool periods of the PDO and AMO, and we are talking little ice age type cooling. Alternately, if some of these do not coincide, the cooling could be less because the various factors work against each other, say a quiet sun during a time of no major volcanic eruptions and warm PDO and AMO. Currently, we have warm phase AMO, cool phase PDO, a good chance of a quiet sun for several decades, and being at the start of a downslope of temperature from this article. Prediction, if no major volcanic eruptions, a little ice age of shorter duration and milder than the Dalton, but still noticeably colder. If when the sun is quietest say 10-20 years from now, there is a major eruption and the AMO is cool, we could have “a year without summer”. The former would be hard for warmists to explain away, the latter would be almost impossible. However, there are enough stupid and mentally lazy people to fool some of the people some of the time with extreme enough propaganda and silencing of critics to call it “extreme weather” and still blame it on CO2, even though this isn’t really possible scientifically.
Finally, about this being like astrology, remember back to the discovery of gravity? Well, it was discovered that big dense objects, like the earth, tend to pull things toward them, and small objects, like an apple, don’t (enough to notice). For many many years after that, and some might say even to today, the actual mechanism for gravity was not understood. Does that mean that gravity=astrology?
About the influences of Jupiter and Saturn being too small, do we really understand what causes active or quiet sun, or exactly what influences the earths magnetism? The answer is, we only guess, just look at the “predictions” of this very solar cycle we are in, for one. Thus, if we see correlations between the one thing and the other thing, when we don’t understand what causes the second thing, we cannot say the first thing does not cause or influence the second thing. If they always vary in synch with each other, we can defiantly say there is a good chance they are somehow related, at the very least, we can then know to look into why (just like we cannot find out the why of gravity until we know that it exists and how much). Thus, if there is a correlation between aurora’s and climate, even if we do not understand it, it is now like gravity, it has gone form an unknown unknown to at least a known unknown. At least now we know the question, before we did not even know to ask it.

The fit on that temperature graph looks impressive, but I also would like to see a correlation.
The 60 year natural climate cycle is well accepted, at least around here. So, the new data is the aurora 60 year cycle.
Otherwise, more evidence for clouds modulating the Earth’s climate, whatever the physical mechanism.
Moreover, the climate may stay approximately stable during the next decades because the 60-year cycle has entered in its cooling phase.
What? Surely the cooling phase will cause cooling. Let’s see temperatures projected out 60 years using this method.
Or is this the new normal science, where no one ever predicts anything.

Title: Is solar variability reflected in the Nile River?
Authors: Ruzmaikin, Alexander, Feynman, Joan, Yung, Yuk L.
Publisher: American Geophysical Union
Citation: Journal Of Geophysical Research, Vol. 111, D21114, doi:10.1029/2006JD007462, 2006
Abstract: We investigate the possibility that solar variability influences North African climate by using annual records of the water level of the Nile collected in 622–1470 A.D. The time series of these records are nonstationary, in that the amplitudes and frequencies of the quasi-periodic variations are time-dependent. We apply the Empirical Mode Decomposition technique especially designed to deal with such time series. We identify two characteristic timescales in the records that may be linked to solar variability: a period of about 88 years and one exceeding 200 years. We show that these timescales are present in the number of auroras reported per decade in the Northern Hemisphere at the same time. The 11-year cycle is seen in the Nile’s high-water level variations, but it is damped in the low-water anomalies. We suggest a possible physical link between solar variability and the low-frequency variations of the Nile water level. This link involves the influence of solar variability on the atmospheric Northern Annual Mode and on its North Atlantic Ocean and Indian Ocean patterns that affect the rainfall over the sources of the Nile in eastern equatorial Africa.

1. Beware confounding:

b) The terrestrial asymmetries quasi-discretely aliasing solar & lunisolar changes are not the same for magnetic & climate variables (for one example the magnetic field has a different pattern from that of ocean-continent heat-capacity contrast), but there are some commonalities since parallel pathways share some features.

And I am not claiming that correlations should not be investigated, and am stating that a proposed mechanism for a correlation has to be physically possible.>>>
Well the specific criticisms you levelled are one thing, the range of possibilities is another. Sure, Jupiter’s gravity has little effect on the Sun. But it does have a very small effect. Astronomers first started discovering planets orbiting other stars by watching for “wobbles” in the position of the star caused by giant planets pulling them in different directions from one part of their orbit to another. So yes, it is small, but it isn’t zero. When you move something as big as the sun just a wee bit, there’s an awfull lot of energy involved, not to mention that the sun is pretty much liquid, so there’s other potential effects different from how a great big rock would behave under the same circumstances.
But that’s not all. While Jupiter’s gravity may not effect the sun a whole lot, it effects the orbits of all the other planets in the solar system, including ours. As for your argument that Jupiter’s magnetosphere is minniscule compared to the sun, sure, but compared to earth’s it isn’t, and it does affect ours.
Further, consider Doug Jone’s comment:
“It implausible that the magnetic fields of Jupiter or Saturn could affect the magnetic fields in the inner solar system, since the solar wind is supersonic- no disturbance created at 5 or 10 AU can propagate back toward the sun any further than the bow shock at each planet.>>>
Well that may be, but who says it has to? Consider Jupiter in an orbital position where it is 90 degrees ahead (or behind for that matter) earth’s position. Now the magnetic field of Jupiter is at a right angle to the solar wind headed directly toward earth, and the magnetic fields and gravitational fields of both planets plus the sun are all interacting ion ways that would absolutely alter the magnetic fields and gravity wells of the inner solar system.
Lastly, while Scafetta focused on the above issues, he did speak also of lunar orbits and tidal effects. Consider that the moon’s orbit is elliptical, and also that it varies in terms of its angle compared to the equator. Never mind the the magnetic fields and gravity wells, just consider the amount of water that the moon, over the course of its various cycles, pulls massive amounts of water from north to south and back again. Do you suppose that affects climate?
I’m betting it does. The number of variances in the orbits of the moon, the earth, and other planets is HUGE. We can’t possibly calculate them all, as the example of the difficulty of calculating from the laws of physics alone how high the tides will be and when. Despite that, we can match the complexity of the known variances in the moon’s orbit to the tides, and wind up predicting them rather accurately without calculating all the physical processes involved. that the variances in the orbits of the various bodies taken into account by Scafetta match so closely to the variances in the arora and can both hindcast and forecast them is remarkable.
While one can argue that the physical processes aren’t known, so it isn’t proof, I’ll suggest another way of looking at it. Given the accuracy of the forecast and the hindcast, and the thousands upon thousands of variables it would take to describe the physical processes, what are the chances the analysis hit a correlation that close based on the orbital positions of the planets and moon alone was a coincidence? Trillions to one?
Not a chance. trillions is way to small.
Home run Scafetta, home run!

Only occurs on one day every 100 years
And the last time it happened, on November 11 1911, an almost supernatural event saw temperatures drop by more than 60F in a single day.
This was the Great Blue Norther, a cold snap which hit the U.S. causing blizzards and tornadoes as well as record falls in temperature.
In Kansas City, it was as warm as 76F (24C) in the morning – but this had dropped to 11F (-12C) by the end of the day…
However, to say that the date is no more than a coincidence would have provided little comfort to those who endured the bizarre weather on the last 11.11.11.
It remains to be seen whether 11.11.11 will produce such surprises this time around, but people should be sure to keep a careful eye on the weather – and on any local Hellmouths – at 11 seconds past 11 minutes past 11 o’clock…

Well, it’s wiggle matching, not my favorite way to deduce a relationship between anything and any other thing. Better than most I’ve seen, but I don’t think motion of the barycenter has that much influence on anything, unless there’s some sort of unknown relativistic jiggery-pokery going on. There are several terrestrial-driven cycles of varying periodicity that need to be accommodated in any comprehensive model. Ellen may have the right idea; seems to make more sense than the planetary hula-hoop / boodycentric model, anyway. Fascinating paper; let the scoffing begin! [Just kidding. Overall, I like it.]

@jimmi_the_dalek:
Does one have to know that the earth is rotating to strongly suppose the sun rises every 24 hours at the equator? I don’t think so. Did Newton specify a mechanism for Gravity? I don’t think so. He observed the forces of nature, and described them. Last I heard Gravity was voted in as another dimension in string theory. Another theory I heard is perhaps it is entangled with some other universe, and that’s why it is so weak. Yet, I’m going to do something I almost never do. I’m willing to bet my life that Gravity is going to effect me tomorrow (not to upset any physicists), but I simply don’t think there is a clear understanding of gravity at present.
That’s where statistics comes in. It would be nice to see if there is a correlation. Then it would make sense to investigate it further, like we still investigate gravity today. Who knows, maybe the warmth of the earth effects the Aurora Borealis.

Do you realise for example that the magnitude of the gravitational field of Saturn on the Sun is less than the effect of the gravitational field of Earth on the Sun? Jupiter is larger but its mass is 1/1000 of the sun’s and it is 800 million kilometers away from the Sun – you work out what the gravitational forces are. Jupiter has a strong magnetic field it is true, being roughly 10 time stronger than Earth’s , but since Jupiter is 5 times as far from the Sun, roughly, the effect of Jupiter’s magnetic field on the Sun, is less than that of Earth’s on the Sun…
——————————————————
Good points. But, how would we detect the earth’s influence ? This is totally synchronized with our year’s cycle. No long term periodic effect can arise. Same with Venus, with a period of much less than 1 year.

Bunk, What is the physical mechanism behind the law of Gravity? What is the physical mechanism behind action at infinite distance? What is the physical mechanism behind Relativity and Time Dilation? What is the Physical Mechanism behind speed and mass? What limits the speed of light?
The only thing that matters in science is predictive ability. If you can predict the orbit of the planets accurately, it makes absolutely no difference in the value of your theory if you understand the mechanism.
Odds are, whatever explanation you have for gravity today, at some point in time in the future that explanation will be overturned as our instruments allow us to explore deeper and deeper into the nature of matter, energy, space and time. It has happened time and time again in the past, no reason to expect it wont happen again.

There is not a clear understanding of the

The 60 year natural climate cycle is well accepted, at least around here
Indeed, so it would seem. But, it is usually described as a “quasi-cycle”, e.g. in that paper, by which they mean it turns out at 60 + or – 4 . The fact that it is not a constant value is enough to rule out an astronomical origin – the orbits of the planets are precise – they do not gain or loose 4 years every now and then. It is not necessary to know exactly how something is caused, to state some of the reasons which could not be the cause.

November 10, 2011 5:46 pm

What the paper does is to show that the mid-latitude aurora records present the same oscillations of the climate system and of well-identified astronomical cycles. Thus, the origin of the climatic oscillations is astronomical what ever the mechanisms might be.

It looks suspiciously like some just can’t get “correlation is not causation”.
The difference between Scafetta and Kelvin is that Kelvin had a well understood physical mechanism as a foundation. Scafetta does not have this.

Without a physical mechanism, this is astrology not science.
In contrast to science, both astrology and CAGW propose a physical mechanism but have no predictive ability better than chance.
Thus, physical mechanism is not a valid scientific test. It tells us nothing, because it assumes knowledge is finite. That assumption is wrong.
There are an infinite number of things about the universe that we don’t know. And, no matter how much we learn, there will still be an infinite number of things we don’t know. So, to say we must know the underlying cause before we can predict, that is not science.
All we need to predict is to observe and find an identifiable, repeating pattern. Armed with that pattern, we can then predict. Thus, early humans predicted the seasons long before we understood the cause. Thus modern humans can predict the tides and the climate.

We have many scientific theories that are very valuable without any understanding of the physical mechanism.
In contrast astrology proposes that are lives are controlled by the planets and their position in the heavens. A clear physical mechanism without any predictive skill.
Now we have CAGW, which proposes that the climate is controlled by industrialization. A clear physical mechanism with the same predictive skill as astrology. Actually, my horoscope is right more often than the IPCC model predictions for post 2000 climate.

Indeed? I know how we can describe and measure mass, inertia, momentum and gravity. I have no idea what mass, inertia, momentum and gravity actually are.
Gravity appears to suggest that all matter in the universe is coupled to all other matter in the universe.
I find it very difficult to understand how an attractive force can connect all matter. So, I have no understanding of what mass actually is and how mass is able to communicate with mass.

Remove A for the last time – check again that X is gone.
Apply A – X should reappear once more.
If you don’t have enough instances of a phenonema, than you are just guessing.
Does the climate cycle up and down repeatedly in response to the aurora every 60 years or so
Then you know what causes what (as long as all other potential influences can be elimanated or controlled.

It [is] implausible that the magnetic fields of Jupiter or Saturn could affect the magnetic fields in the inner solar system, since the solar wind is supersonic- no disturbance created at 5 or 10 AU can propagate back toward the sun any further than the bow shock at each planet.

How do you know there is no dipole feedback at 90 degrees to the ecliptic and how would you propose checking for the existence of and measuring such an effect with the solar wind roaring through, possibly inducing changes in the former? Are we not looking at dynamos within a dynamo here? Only asking 🙂

Mark ro
November 10, 2011 6:45 pm

According to Robert Nemiroff and Jerry Bonnell of NASA,” the solar bow shock may lie at around 230 AU from the Sun.” 5.2 Astronomical Units is the average distance of Jupiter from the sun.The solar wind streams off of the Sun in all directions at speeds of about 400 km/s (about 1 million miles per hour). Magnetism moves at the speed of light. Calculating interactions at this level is beyond my ability, sadly. The way I see it, if the sun’s influence reaches Jupiter as is clearly seen suggesting no interaction is implausible.

I don’t think people get my initial statement….
The authors of that paper have an apparent correlation , and they suggested a mechanism. But their mechanism (gravitational and magnetic fields due to Jupiter) is physically impossible. So their proposed mechanism is in the realm of astrology, not physics. You don’t like that observation? Well tough, learn something about the relative magnitudes of forces. In science you have to be quantitative not just qualitative – if a given proposed cause is not of a magnitude to result in an observed effect of a particular size, then it is not the cause.
And stop making comments about the IPCC and climate science – I am not trying to defend them, because two wrongs do not make a right. Scepticism properly applied looks in both directions. If something is rubbish then it should be described as that even if it would support something you want to be true

“Eleven frequencies with period between 5 and 100 years closely correspond in the two records. Among them, large climate oscillations with peak-to-trough amplitude of about 0.1 and 0.25°C, and periods of about 20 and 60 years, respectively, are synchronized to the orbital periods of Jupiter and Saturn.”
I know you don’t like to hear this, but:
This corroborates Landscheidt – Earth climate correlates with the output from the Sun which in turn correlates with cycles in the position of the centre of the solar system relative to the centre of the Sun driven by variations in the orbital pull of the major planets.

Part of a growing acknowledgement of a link between top down solar effects on the atmosphere and air circulation patters.
Keep it simple.
Solar changes affect the vertical temperature profile of the atmosphere especially towards the poles. Mechanism currently unclear but in my view related to atmospheric chemistry involving ozone but with different effects at different levels.
The result is a change in the degree of zonality/meridionality/latitudinal positioning of the mid latitude jets in particular but most likely the entire surface air pressure distribution too.
Long looping jets increase global cloudiness. Shorter more direct jets reduce global cloudiness. No need for cosmic rays to affect cloudiness but there may be some such effect.
I think the consequent effects on global albedo and solar energy uptake by the oceans are by now pretty much a given.
There you have the entire climate change phenomenon in a nutshell. Not even any need for any change in total system energy content to occur. Just a redistribution of energy within the system as the rate of energy flow through the system responds to air circulation changes. We perceive that as climate change because the direction of air flow across surface sensors changes as the positions of the permanent climate zones shift relative to those sensors. The satellites record much smaller changes as the system adjusts the rate of energy leaving the system in order to maintain radiative balance.
The radiative balance is constantly maintained by internal system adjustments that always act negatively to any forcing that tries to change the system energy content. It even deals with the faint sun paradox whereby the Earth’s temperature has stayed much the same over billions of years despite a 30% increase in solar output.
The shifting climate zones have made fools of climatologists.

Which of course is my point. Which I already made when I pointed out that , for example, the effect of Jupiter’s magnetic field on the Sun is less than the effect of the Earth’s magnetic field on the sun. Do we worry about the effect of the Earth’s magnetic field on the Sun? No? Then why should we consider the effect of Jupiter’s if is less than half that (you do know how I calculated that I suppose?)

Dr. Scafetta writes in and attaches the full paper in email to me (Anthony) this week saying: […]
Note that aurora may form at middle latitude or if the magnetosphere is weak, so it is not able to efficiently deviate the solar wind

I’m afraid this is yet another bad case of cyclomania. The magnetosphere being weak and not able to efficiently deviate the solar wind is just nonsense, pure and simple. The Earth’s magnetic field changes only very slowly [by about 1 in a thousand per year] and the size and extent of the magnetosphere is controlled by the dynamic pressure of the solar wind and changes just the opposite way of what Scafetta describes [“During the solar cycle maxima the magnetosphere gets stronger” – whatever that means]. Here is the time evolution of the solar wind flow pressure during the space age: http://www.leif.org/research/Solar-Wind-Flow-Pressure.png
The reference in the article to Lord Kelvin’s tide calculator is a bit misleading. It says: “conceived by Lord Kelvin in 1867,which is currently the only methodology that accurately predicts tidal heights.” Modern tidal calculations rely on the Doodson Numbers [ http://en.wikipedia.org/wiki/Arthur_Thomas_Doodson ] which give the position of the Sun and the Moon, and which are curve fitted to a Fourier expansion of tidal data as observed at the location in question. No physics here, pure curve fitting. During the D-Day invasion, knowledge of the tides was crucial and the British sent in under cover of darkness crews in small boats and mini-submarines to actually measure the tides so that they could be curve fitted to the Doodson Numbers. The tide predictions work because the is a well-known physical cause, Scafetta’s curve fitting has no physics behind it.

jimmi_the_dalek,
Fair point about quasi-cycles. I learned something.
Stephen Wilde,
The radiative balance is constantly maintained by internal system adjustments that always act negatively to any forcing that tries to change the system energy content.*
That’s pretty much my view, although I’d substitute feedbacks for adjustments, but we are left with the puzzle of what does cause the known climate variation. It has to be factors that affect the feedbacks themselves. Cloud modulation is top of my list.
* this allows some effect from radiative forcings such as GHG, but limits it through increasingly negative feedbacks. So increasing CO2 could have some effect that stops at some point irrespective of how much CO2 increases beyond that point, which is essentially what we have observed since 1960.

A thought provoking article, but this supposition;
“perhaps the strength of the Earth’s magnetosphere is also regulated directly by the gravitational/magnetic forces of Jupiter and Saturn and the other planets whose gravitational/magnetic tides may stretch or compress the Earth’s magnetosphere in some way making it easier or more difficult for the Earth’s magnetosphere to deviate the cosmic ray.”
appears dubious, which make me more skeptical about the rest of it.

In terms of aurora, they “primarily occur in the thermosphere. Charged particles (electrons, protons, and other ions) from space collide with atoms and molecules in the thermosphere at high latitudes, exciting them into higher energy states. Those atoms and molecules shed this excess energy by emitting photons of light, which we see as colorful auroral displays.”
but while “the thermosphere is considered part of Earth’s atmosphere, the air density is so low in this layer that most of the thermosphere is what we normally think of as outer space. In fact, the most common definition says that space begins at an altitude of 100 km (62 miles), slightly above the mesopause at the bottom of the thermosphere. The space shuttle and the International Space Station both orbit Earth within the thermosphere!”
“Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere. When the Sun is very active and emitting more high energy radiation, the thermosphere gets hotter and expands or “puffs up”. Because of this, the height of the top of the thermosphere (the thermopause) varies. The thermopause is found at an altitude between 500 km and 1,000 km or higher.”

1: it was not the 14th century but 1550-1650
2: in the year 1600 the magnetic pole was at latitude 85.03N degrees and longitude 306.55E. Today it is at 82.53N and 276.37E, so London was actually at a lower magnetic latitude back in 1600, so would see fewer aurorae.

Things are not always as precise as they seem. For example at:

It did not pass through its perihelion until 13 March 1759, the attraction of Jupiter and Saturn having caused a retardation of 618 days.”
Also, Jupiter and Saturn meet every 19.85 years. Since it is not an even 20.00 years, there will be different seasons on Earth with every meeting. In addition, other planets such as Venus and Uranus also have their influences so years could be added or subtracted. As well, the sun would be at different phases in its sunspot cycle each time so it is not surprising that we have 60 + or – 4.

My point was interaction between the bodies. If the sun’s influence reaches Jupiter then they interact. Any influence however small should be considered. For example: My girlfriend who is 4’9″ frequently alters my position on things even though I’m a foot taller and a hundred pounds heavier.

Jimmi, can you answer this question:
Yes I can actually – it is of the order of 10^23 (ratio of the masses since the distance of myself from the earth the same as the distance of the earth from me) Which is tiny.>>>
OK, so the question now is, are you prepared to follow some math and perhaps learn something?
The question is actually a trick question of sorts. The ratio is exactly 1:1
No, I’m not kidding. The formula for calculating the amount of force that two bodies exert on each other is:
F=(G*m1*m2)/r^2
Where F = Force
G is a constant
m1 is the mass of one body (let’s say you)
m2 is the mass of the other body (let’s say earth)
r is the distance between the centres of gravity of the two masses.
So let’s go through the assumptions you’ve made to show why they are commonly made mistakes.
Assumption 1: The ratio of gravitational force is determined by the relative mass of the two bodies. Incorrect. It doesn’t matter if YOU are m1 and the earth is m2 or the other way around. The force between the two is exactly the same. If the earth exerted more force on you than you exert on the earth, then you would actually move the earth simply by standing on it.
Assumption 2: The distance between you and the earth is tiny. Again, common assumption that since you are standing on it, the distance is zero. But it isn’t because r in the formula above is calculated between the centres of gravity of the two bodies. The diameter of the earth being about 13,000 kilometers, r is, in this case, about 6,500,000 meters. Not close to zero at all.
In fact, if the distance between two bodies approaches zero, then the force between them approaches infinity because 0^2 is still 0 and anything divided by zero is infinity. If you followed this far, you should now understand what a “black hole” is. When matter is compressed so much that the distance between any two particles starts to approach zero, the force between them becomes so great that it collapses time and space. Trust me, though you might hug the earth with all your might, you’re in no danger of creating a black hole.
Now take what you’ve learned and apply it to some of the things you’ve said. How much force does Jupiter exert on the Sun? Answer: exactly as much as the Sun exerts on Jupiter.
Now take the next step. Jupiter orbits the Sun, and I’m betting if I asked you exactly at which point inside the Sun it is the Jupiter orbits around, I’m guessing that you, like most people, would say the centre of the Sun. You’d be wrong again.
The answer is that when two bodies are in orbit, their orbits revolve around the centre of gravity of the two bodies taken together as one. For you standing on the earth surface, your mass is in fact so small that you probably can’t measure the change in centre of gravity of you and the earth if your mass were to instantly double. But it isn’t zero. Juptier on the other hand, is big enough to cause the centre of gravity of it and the sun to be somewhere between the centre of the sun and the surface of the sun. Both Jupiter and the Sun orbit around that centre of gravity. So, Jupiter being rather small compared to the Sun, has a very large orbit, and the Sun has a very small orbit. But if you were so far away in space that all you could see was the Sun as a tiny point of light, and you had instruments accurate enough, you would be able to figure out that something the size of Jupiter exists, because over time, you would notice that the star isn’t sitting still, it is wobbling around itself.
Now let’s keep going and talk tides. The moon raises tides on earth, even though it is only one sixth the mass of the earth, it raises tides of several meters in some cases, and does so based on a 24 hour rotation. Now certainly, Jupiter is far less than one sixth the mass of the Sun, but it has YEARS to raise a tide on the sun, not hours.
OK, that’s enough physics for me tonight.

Also deleted were Weekly Pokernight 4.2 and Annual Fishing Trip 7.6. I considered trying to downgrade back to Girlfriend 11 (any version) but apparently the upgrade wipes out the existance of the previous Girlfriend version. I was tempted by the potential return of Girlfriend 6.0, but was advised by Wife 1.0 that further attempts to communicate in any way shape or form with Girlfriend 6.0 would invoke Legal Proceedings 2.0. Not certain what that is yet, but it sounds bad.

November 10, 2011 8:56 pm

The greater magnetic and gravitational fields of the Galaxy permeate the whole solar system and pass through the entire system. Originally we had flat earth thoughts, then heliocentric mindedness, where most people are stuck, the local galaxy we are invested in, is slave to the greater local super group’s magnetic fields and gravitational influences. To not be aware of the constructiveness of the whole system is to be lost to the whole truth. The influences of the galaxy push magnetic fields into the poles of all the planets and the sun, the sun responds with the rest of the solar system to the flux in their strength, and balance is struck between each and all bodies in the system.
http://research.aerology.com/natural-processes/solar-system-dynamics/
Excerpt; Posted: January 31, 2011 by tallbloke in solar system dynamics
24 Recent update, reflecting the ideas I have found in the rest of these blog stuff links by others.
All of the universe affects the rest of it, as all sits in a common bowl of gravitational and magnetically connected and driven mass of ions and regular atoms, that respond to the basic physics detailing the “normal rules or laws”. To think that there are voltages or ions that move without magnetic fields attached violates first principles.
The stars are surrounded with a ion shell the heliosphere, that protects them [like ferro fluid particles with oxalic acid coats to keep them from merging as they float around] from running into each other the outer surfaces are composed/covered with free electrons hanging on the outer edge of the magnetic fields.
The mutual static repulsion keeps the stars separated just as mutual static repulsion keeps the neutralized moisture in a cloud from condensing. As the background cumulative charge gradient increases it reduces droplet size and polarizes them. With the added side effect of lowering albedo by becoming more transparent to short wave sun light.
The galactic magnet fields are also influenced by these same basic rules of action as well, which leads me to the conclusion that the interactions of the composite system of magnetic interactions from the rotation of the Galaxy, and the declinational movement of the solar system in that larger frame of reference, as well as the density waves that propagate around driving the spiral arm flux variances give rise to the longer term cyclic climatology of the Earth.
The heliopause of our sun Sol, seems to have auroral knotted bands (recently spotted ribbons of ion activity) on its leading side as it progresses through the interstellar gases and dust clouds, the solar system passes through in its travels. I think that this is due to the conductance of the galactic fields into and through the heliopause, coupling through the polar regions of the sun and planets, altering the interactions of inertial and inductive drives to near stable states at or near equilibrium.
The residual shifts in balance are felt as steering currents in the slow transition of the orbital dynamics and swaying of the solar system as it winds its way through the static charges on heliopause, as Sol makes its way through the gravitational attractions and radiation pressures gauntlet, shoved around ever so slowly by the rest of the individual stars.
The magnetically permeable inductive components of planetary bodies and their moons are susceptible to Ohms laws, and Maxwells power equations, that drive the interactions of electromagnetic forces that equally apply to the full frequency spectrum from near DC standing magnetic fields to the most energetic particles seen.
All electronic gadgets, radios, toys, and computers work with these modulation techniques derived from compounding the effects of the individual components, through inductive and capacitive couplings into and through semi conducting amplifiers, filtering for the frequency range required for the end function desired. The formula for solving the initial circuit design has long been known and has been taken to almost single atomic scale in state of the art semiconductor manufacture.
So we should be able to understand, by the application of these common formula, and to figure out from the sizes of the forces at work, the interactions of the sun with the planets and their moons, by determining the shifts of flux of the magnetic fields, with the shifting density and speed of the solar wind, in their resultant periodic harmonic interactions as they became stable over the past 4.8 billion years.

If aurora were visible in London in late 14th century they they must have been incredibly powerful. The magnetic pole has probably moved a considerable distance since then. It is currently moving at a rate of 37 miles / year toward Russia but the rate and direction changes over time.
Leif Svalgaard says: November 10, 2011 at 8:01 pm
1: it was not the 14th century but 1550-1650
2: in the year 1600 the magnetic pole was at latitude 85.03N degrees and longitude 306.55E. Today it is at 82.53N and 276.37E, so London was actually at a lower magnetic latitude back in 1600, so would see fewer aurorae.
3) many aurorae were seen because the Sun was quite active.

Here is a map with the North Magnetic Pole location back to 1600;

According to NOAA, and in reasonable agreement with the other sources above,
in 2010 the North Magnetic Pole was at latitude 84.742N and 129.077W, whereas in 1600 it was at 74.833N and 111.690W.

Hi Anthony
I’ll be frank and say I can’t tell the difference between this and some of the cycl0-mania calculation papers that have been sent to me over the last few years.
The strongest argument in my opinion is that the tides are calculated in a similar manner, so if true and the data fit backwards and forwards in time one should take it seriously. I have often argued that the planet orbits are like a giant clock against which there will be a coincidence of any periodic manifestation, in a similar way that we use 24 hour clocks for defining time changes . I keep an open mind as far as causality, though there should not be much doubt about sun and moon effects, as they are strong enough .
Yes, time will tell, as with all climate related models/predictions.

November 10, 2011 9:51 pm

First I would like to thank Anthony for the post about my article and all readers who have found my paper intersting.
Just a few thoughts about some of the numerous comments.
I see that some persons insist with the thesis that a finding would be scientific only if everything is already fully understood and clear. However, I need to say that in scientific research one does not start with a full and complete knowledge about an issue. The full and complete knowledge of an issue is the conclusive step of a scientific research not its beginning. In scientific research people start with the data and try to understand what the data tell us. Then they try to model the phenomenon and/or propose possible mechanisms. This is what makes a theory. A specific proposed theory may then be further supported or rejected by additional research on the topic. This is the way in which science, in every field, progresses. So, there is nothing wrong if a single paper on an ongoing research does not explain in detail every possible issue related to the studied phenomenon, in particular if, as it is in this case, the phenomenon under study is extremely complex. And there is nothing wrong is such a kind of paper may contain some conjectures which may also be found wrong in the future.
About the comments from Leif Svalgaard, I need again to invite him to read my paper before criticize it and to do that with a little bit of open mind (of course he does not need to open it too much because we do not want that his brain get lost somewhere).
About the tides Svalgaard does not really appear to understand the issue. Time ago he was claiming that nobody in the past, before Newton, knew that the tides were induced by the moon. I needed to prove to him that in the past, on the contrary, everybody knew that the tides were induced by the moon even if the people did not know about Newtonian mechanics.
Now he insists that I do not understand Kelvin’s argument about the tides because in his opinion I ignore Doodson’s work, which by the way I have referenced in my paper together with the work of Kelvin.
Svalgaard does not understand the fact that it is not possible accurately calculate and predict the tides using the fundamental law of physics because of the enormous physical complexity of the problem, which is not limited to only know the existence of the gravity but also requires a detailed knowledge of a lot of other things including thermodynamics, fluido-dynamics and the fundamental local resonances. To overcome this ignorance issues Kelvin proposed a harmonic model based on astronomical cycles without putting any physics in it, but using astronomical geometry. Doodson simply expanded the argument of Kelvin.
That the method of Kelvin does not require any modern quantitative physics but only a qualitative argumentation based on empirical astronomy is proven not only in the same works of Kelvin on the topic but also by the fact that an equivalent methodology was adopted since ancient times to predict the tides. One medieval work that addresses the issue and explains quantitatively how the tides could be predicted based on astronomical cycles is the De temporum ratione (The Reckoning of Time) by the Northumbrian monk Bede in AD 725: quasi 1000 years before Newton.
http://en.wikipedia.org/wiki/De_temporum_ratione
Perhaps Svalgaard has a very restricted understanding of what constitute science which does not appear to me to coincide with what scientists involved in research normally think.

Because the concept of the ‘magnetic pole’ is a bit complicated. If you are walking on the ground with a compass or a device measuring the dip of the needle you might find a point where the horizontal force is zero and the magnetic field is vertical, so that is one definition of the ‘magnetic pole’ [and the one your sources show. But that is not the pole the particles that create the aurorae see. That is called the ‘corrected geomagnetic pole’. And those were the numbers I quoted. For recent years it can be computed here: http://omniweb.gsfc.nasa.gov/vitmo/cgm_vitmo.html The reason for the difference is that the small-scale magnetic sources that control the field on the ground disappear or weaken with height, so that out in the magnetosphere the field is simpler and different. For times before 1900 a different model and method is needed, but I have such back to 1590. In general you can trust what I say as being relevant and factual.

for example, the effect of Jupiter’s magnetic field on the Sun is less than the effect of the Earth’s magnetic field on the sun. Do we worry about the effect of the Earth’s magnetic field on the Sun? No ?
———————————-
That does not make your point plausible.
The earths influence has a cycle of exactly 1 year. It is then not detectable as it is completely mixed with seasons and eccentricity of the orbit.
The most important planetary long term cycle then comes from Jupiter.
The influence doesn’t have to be exactly 60 years, as, for example, cosmic rays and sun output are not as reliable as planetary orbits.
The effect could even be amplified by an oscillation through exitement every 60 years for billions of years, either an oscillation within the sun or in our climate system or even around an eigenmode.
This may all not be true, but your just saying it is impossible is more astrology than science.

A deeper understanding of the earths spheres and the electro-magnetic throughput of both energy and matter are much needed, Obviously, the best studies ocurr when the sensors are within the medium and this is difficult for measuring the upper troposhere, the mesosphere, the stratosphere and all layers within the ionoshhere. As we see molecular matter going through breakup phases straight to their atomic form, what is exactly happening? More importantly what happens during periods of increased magnetic influences (CME’s and all their proton, electron, X-ray flows etc..) and the angles that they arrive and the status at the event times (low to absent D layer, day or night, sporadic E layer properties etc…)?
We know very little about the transport of mater and energy entering and leaving the six spheres surrounding our planet. The mechanisims and structures are being studied in a number of ways, but the mediums we’re looking at are a tough one to measure. We’ve had a huge number of satellites with their sensors monitoring the topside and the magnetotail to the cusps, but the data collected is minimal and we certainly have a long way to go…

http://en.wikipedia.org/wiki/Galileo_Galilei :
Galileo, Kepler and theories of tides
[24] Galileo considered his theory of the tides to provide the required physical proof of the motion of the earth. This theory was so important to Galileo that he originally intended to entitle his Dialogue on the Two Chief World Systems the Dialogue on the Ebb and Flow of the Sea.[25] The reference to tides was removed by order of the Inquisition.
For Galileo, the tides were caused by the sloshing back and forth of water in the seas as a point on the Earth’s surface speeded up and slowed down because of the Earth’s rotation on its axis and revolution around the Sun. Galileo circulated his first account of the tides in 1616, addressed to Cardinal Orsini.[26] His theory gave the first insight into the importance of the shapes of ocean basins in the size and timing of tides; he correctly accounted, for instance, for the negligible tides halfway along the Adriatic Sea compared to those at the ends. As a general account of the cause of tides, however, his theory was a failure.
[28] Galileo dismissed as a “useless fiction” the idea, held by his contemporary Johannes Kepler, that the moon caused the tides.
http://en.wikipedia.org/wiki/Tide
“In the 9th century, the Arabian earth-scientist, Al-Kindi (Alkindus), wrote a treatise entitled Risala fi l-Illa al-Failali l-Madd wa l-Fazr (Treatise on the Efficient Cause of the Flow and Ebb), in which he presents an argument on tides which “depends on the changes which take place in bodies owing to the rise and fall of temperature. “[citation needed] He describes a precise laboratory experiment that proved his argument.[36]”
To overcome this ignorance issues Kelvin proposed a harmonic model based on astronomical cycles without putting any physics in it
As I said, curve fitting, but with a sound physical basis.

The existence of a natural 60-year cyclical modulation of the global surface temperature induced by astronomical mechanisms, by alone, would imply that at least 60–70% of the warming observed since 1970 has been naturally induced.

The remaining 30-40% of the warming has been manufactured by cooking the books
I personally look forward to reading more about the electric properties of the ionosphere… fingers crossed that WUWT doesn’t shut down this line of investigation.

Interesting.
“The provided code calculates the Corrected GeoMagnetic (CGM) coordinates and several other main geomagnetic field parameters for specified points at the Earth’s surface (geocentric coordinates) or in near-Earth space (and vice versa).”
“By definition, the CGM coordinates (latitude, longitude) of a point in space are computed by tracing the DGRF/IGRF magnetic field line through the specified point to the dipole geomagnetic equator, then returning to the same altitude along the dipole field line and assigning the obtained dipole latitude and longitude as the CGM coordinates to the starting point. At the near-equatorial region, where the magnetic field lines may not reach the dipole equator and where, therefore, the standard definition of CGM cooordinates is irrelevant, a new approach based on a Bmin value along the given magnetic field line is developed and applied. This approach is discussed in detail by Gustafsson et al. [1992].
Because the “local” CGM meridian is non-orthogonal to the “local” CGM latitude, we approximate the “local” direction of this meridian.by the great-circle arc, connecting the given point (station) and the corresponding (North or South) CGM pole. Therefore, an azimuth of this arc with respect to the local geographic meridian (which is also the great-circle arc, connecting the station and the corresponding geographic pole) is our “meridian” angle: positive to East from the North geographic meridian and positive to West from the South geographic meridian.
According to the definition of geomagnetic coordinates under the dipole approximation, the magnetic local time (MLT) is measured by the flare angle formed by two planes: the dipole meridional plane, which contains a subsolar point on the Earth’s (or any altitude) surface, and the dipole meridional plane which contains a given point on the surface (that is, the local dipole meridian). This definition cannot be applied to the CGM coordinate system because the latter is non-orthogonal and the CGM meridians do not cross the magnetic equator elsewhere [cf. Gustafsson et al., 1992]. Therefore, the dipole-based approximation is invalid in defining MLT for the CGM coordinate system.
Here we propose to utilize another approach in defining MLT for the CGM coordinate system. Let us assume that the station is located at local midnight, i.e., at some UT instance the local geographic meridian is at 00 LT and the station is “behind” the geographic pole with respect to the Sun. If the Earth rotates through an angle (measured in UT hours and minutes) so that the station’s local CGM meridian (approximated by the great-circle arc) is moved to 00 MLT, then the station is “behind” the CGM pole with respect to the Sun. This UT instance (in hours and minutes) would be “a local MLT midnight in UT” which is computed in our algorithm.”

Not “everybody” Nicola. Galileo took Kepler to task for his “astrological” claim that the tides were caused by some mysterious force exerted by the moon. Galileo wrote in the Dialogue Concerning the Two Chief World Systems that the tides were caused by the rotation of the earth causing the oceans to slosh about. It was the Pope’s scepticism of Galileo’s idea that led to Galileo putting the Pope’s words into the mouth of Simplicio (Idiot) in the Dialogue and his trial for heresy. The heresy was ridiculing the Pope and had little to do with Copernic’ heliocentric theory.

There is not a clear understanding of the cause of gravity, but there is a very clear understanding of its magnitude and how that depends on the mass and separation of objects. Likewise magnetic fields. It is because the magnitude is understood that this paper is implausible in the extreme.

Perhaps there is a third element if the magnetic and gravitational influences are too weak… a third force that dares not speak its name….

An aurora is a natural light display in the sky particularly in the high latitude regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere. The charged particles originate in the magnetosphere and solar wind and are directed by the Earth’s magnetic field into the atmosphere.

In scientific research people start with the data and try to understand what the data tell us.
The auroral counts are difficult to calibrate, but we know that when mid-latitude aurorae occurs they are always accompanied by magnetic disturbances. And we have fairly good data about those going back to the 1840s. So, they should show a 60-yr period if there is one. Here is the FFT power spectrum of the geomagnetic Ap-index back to 1844: http://www.leif.org/research/FFT-Ap-1844-2011.png as you can see there is a sharp peak at 0.5 year [this is the well-known semiannual variation – that activity is smallest at the solstices], and a broad peak around 11 years [this is the solar cycle variation], but no trace whatsoever of a peak anywhere near 60 years, although we have almost three intervals of 60 years.

But their mechanism (gravitational and magnetic fields due to Jupiter) is physically impossible.

Right up there with confusing correlation with causation: thinking you have proven a negative.
Well tough, learn something about the relative magnitudes of forces.
Something about the relative magnitude of forces like: if the sun can swing a mass the size of jupiter around the solar system, then jupiter can swing a mass the size of itself around the interior of the sun?
But, it is usually described as a “quasi-cycle”, e.g. in that paper, by which they mean it turns out at 60 + or – 4 . The fact that it is not a constant value is enough to rule out an astronomical origin – the orbits of the planets are precise – they do not gain or loose 4 years every now and then.
The period and magnitude of the ocean tides changes a little from cycle to cycle, therefore the moon, with its precise orbit, cannot be the origin of tides?
In science you have to be quantitative not just qualitative – if a given proposed cause is not of a magnitude to result in an observed effect of a particular size, then it is not the cause.
So, pulling the trigger on a gun cannot be the cause of a murder, because the four or five pounds of force it takes to pull a trigger is not of deadly magnitude?

… both, longterm global temperature reconstructions and high frequency simulation and climate forecast (month) can be calculated very simple with the solar tide functions of Mercury outwards the Sun, but it do not need the frequency of the Earth Moon.
What is true that all matter (or moving matter) in the universe – including the Earth Moon – is connected i.) by a field that local let matter be in harmony with that field. Because each moving object owns an angular momentum since the Big Bang (which is strong related to the magnetism of the bodies from Moon to big stars), which is not to be destroyed, but only to ‘transferred’ to other objects, common physics has problems thinking mostly in causal mechanism like a steam machine.
But this thinking cannot be used to explain resonance phenomena – like the frequency resonance of Jupiter and Saturn 2.672 nHz : 1.0685 nHz = 2.50078 or 5:2 – of low integer ratios. There is no clear acting direction of force which source has an effect the other object. Same problem in the solar system.
Because of the resonance phenomena, which are ever of harmonic nature, there are quantitative frequencies detectable, which are also connected to the Moon’s frequencies and solar frequencies, but these frequencies are not to be found in global temperature spectra like hadcrut3 . And because this simulation of the high frequency terrestrial climate spectra is based on heliocentric = solar tide geometries including the Earth frequency, the Moon has approximately the same heliocentric frequency as the Earth.
However, it seems that the solved climate code is not a point of interest, but a lot of sayings what is NOT (science) without showing by arguments. But that itself is not science.

Interesting, kudos to Scafetta. Much more convincing that his last paper on this .
It looks like he is using HadCrut3 to judge by the divergence <1880. This is one area where I think the Berk-EST may be nearer the mark. Their method seems more accurate with the older more noisy data and would follow the trends Scafetta's synthesis more closely.
Once B-est have fixed the fact the magnitude of short-term swings and long term rise is probably at least 50% more than it should be , I think they have a skillful means of extracting temperature.

Crosspatch and others comented on my original post as to why there were so many reports of the aurora borealis being visible from the south of England that I noted in the historic accounts of 1550 to 1650 during a visit tothe Met office archives
Crosspatch said;
“My guess is that the skies of the South of England were much darker at night in 1550-1650 than they are today. Aurorae that might have been visible then may be completely invisible now. Also, London is at about the same latitude (51degN) as Winnipeg, Canada (49 degN). Winnipeg sees aurorae rather often.”
What was equally interesting and may or may not be relevant, is how many earthquakes were mentioned during the same time period. They were never serious as here in the UK we tend to have tremors rather than full blown earthquakes, but the[y’]re sufficient in numbers that they warranted a complete section in the reference book I was reading.

If one adds a 60-yr wave: http://www.leif.org/research/Ap-1844-2011-plus-60yr-wave.png one does get a strong peak near 60 years: http://www.leif.org/research/FFT-Ap-1844-2011-plus-60yr-wave.png , but since the original data does not have such a period, no peak is seen for that.

Observe that a large fraction of the solar system, in its equatorial plane, gets engulfed with the CME.

Underlining effects are close circuits (closing at the solar surface) of magnetic field and electric currents. Both magnetic field and electric current are partially short-circuited by the huge magnetospheres of both Jupiter and Saturn (known as magnetic reconnection).
Every 19.859 years (Leohle and Scafetta -20years cycle) this short-circuiting is particularly effective since both planets find themselves in the same direction. Now imagine our little Earth zipping in between, its tiny magnetic field gets zapped by these huge currents:

Heliosphere is highly squashed in the head on direction so the effectiveness of the zap is far more severe when both Jupiter and Saturn find themselves in this head on direction. This happens every 59.5 years (Leohle and Scafetta -60years cycle).

No. they are not, and the solar wind is carrying everything away from the Earth, Jupiter, and the Sun in any event. The wind is 11 times supersonic, which means that it moves away from the Sun eleven times faster than magnetic and electric effects can travel upstream towards the Sun. I have lost track of how many times this has been pointed out to you. Perhaps this time it will sink in…

Without a physical mechanism, this is astrology not science.
Science is a method to recognise what IS in nature. That what is in nature is nor to be shown, but to recognised. If truth would to be shown, it would have an observable existence. But it has not. It has only speakers about nothing.
It would be a basic contradiction, if nature is to be divided in more than one order, because then it would be possible that something can be true AND at the same time untrue. It is the own recognition of a scientist that it is impossible that something can be true AND at the same time untrue.
There is only one nature, but a lot of fallacies in statements.
Physics. Physics is the part of science, which deals exactly only with occurrence in the outer world, named forces. Logic, math, algebra, music, harmony are because they have neither a mechanism nor a detectable force NOT part of physics.
Astrology is the science of the logic of the objects the Greeks have called planets, the wandering stars on the sky. Physicians can understand that each frequenting mass multiplied with Plancks constant h is equal to energy E in [eV]. This implies the Doppler effects of the moving surface of the Earth towards East or move away from West.
Astronomy is the science of the laws of the moving planets, J. Kepler has shown in his book Astronomia Nova.
If one is arguing ‘astrology’ seriously, without showing that it has any existence, it is called a straw man fallacy, because it is only used to promote the ‘spirit of the holy science community’. > ‘It’s a fallacy because it fails to deal with the actual arguments that have been made.’ <.
If one is arging valid, he acknowledge the basics of philosophy, and from this it is clear that ‘causal mechanism’ what ever this means, cannot beat the basics of philosophy.
Causality. In nature there are some things not to be proved like endlessness, or a beginning. Because of this causality should have a beginning and an end. But this is in contradiction with the definition of causality and/or a mechanism. A mechanism cannot have and end. Thermodynamicers do know this.
Sayings, personal sayings (avoiding arguments) as authority of the science community are that dirt that covers in public the hidden truth in nature, only to recognize in the own consciousness.
Moreover, like the CO2 dirt, much hard clean work has to be done – like the WUWT blog – which binds people, who are interested in valid scientific arguments, about what IS.
What is real in physics? A velocity? A space in meters? A time in seconds or years? Has time a beginning? Has time an end? Has space and end? Both are no forces, but only idols of the physicians in QM or climate science and the science community.
The phase difference phi = 2 Pi * (R-1) or phi = 2 Pi * [(t2/t1)-1] with R = t2/t1 and t1′ = c’ and t2 the second tune of the interval in the Pythagorean scale of the science of music are based on integer ratios. Most people and children do acknowledge these ratios as true harmony.

9/5 b(b)' (4x72°)288°
2/1 c'' 360°

In a 2Pi circle like the ecliptic viewed from a geocentric perspective astrologers like J. Kepler do know this language of the stars, and do understand it, because they have learned the language. Physicians have not.
It is a simple but valid argument that if the geometric ratios in the music scale have a reality in a living consciousness, the very same geometric ratios in the sound of the planets must have a reality in this one nature.
The most important (heliocentric) aspects to simulate the terrestrial climate are the conjunction and the opposition, and J. Kepler
has said
this for geocentric aspects. These aspects both are well known as tide functions and it takes no wonder that a summing of the tide functions of 11 celestial bodies in the solar system leads to a simulation of the high frequency global climate as published as hadcrut3 data:

A stronger field means fewer aurorae. The influence of the solar wind on the Earth increases if the screening effect of the Earth’s magnetic field decreases. As the field has weakened the past several hundred years, geomagnetic activity and aurorae have increased.

At the same time Johannes Kepler correctly suggested that the Moon caused the tides, based upon ancient observation and correlations, an explanation which was rejected by Galileo. It was originally mentioned in Ptolemy’s Tetrabiblos as being derived from ancient observation.

I suppose the Daily Mail was trying to be cute (do they ever try to be newsworthy?), but the “Witch of November” – an extreme extratropical storm in the Minnesota area is a well studied event.

To those who claim I have not read the paper – I have read more of it than the people who think it is about cosmic rays. Also, the relation to astrology is simple – science has to be quantitative not just handwaving. Do you realise for example that the magnitude of the gravitational field of Saturn on the Sun is less than the effect of the gravitational field of Earth on the Sun? Jupiter is larger but its mass is 1/1000 of the sun’s and it is 800 million kilometers away from the Sun – you work out what the gravitational forces are. Jupiter has a strong magnetic field it is true, being roughly 10 time stronger than Earth’s , but since Jupiter is 5 times as far from the Sun, roughly, the effect of Jupiter’s magnetic field on the Sun, is lessthan that of Earth’s on the Sun. And I am not claiming that correlations should not be investigated, and am stating that a proposed mechanism for a correlation has to be physically possible.
And for those who reckon I am a troll, or a “warmist” – I am neither – but I realise than skepticism has to work in both directions – and this paper is BS.

Jimmy, you like back of the envelope maths. So from http://www.universetoday.com/15141/mass-of-jupiter/ we have the statements:
“The mass of Jupiter is 1.9 x 1027 kg. It is hard to fully understand a number that large, so here are a few comparisons to help. It would take 318 times Earth’s mass to equal Jupiter’s. Jupiter is 2.5 times more massive than all of the other planets in our Solar System combined. Jupiter is actually so massive that if it gained much more mass it would shrink.”
Now you are emphasizing that the effect of gravitational fields are extremely small. But how much force is necessary to keep a planet with a mass of 1.9 x 1027 kg in orbit? The continual velocity change requires a continual acceleration toward the Sun. You think that this requires only an infinitesimally small force?
Stars like the Sun are being identified as having planets around them by the fact that the stars ‘wobble’ due to the orbit of their planets around them. Or more correctly the stars and their planets are orbiting their barycenter – their center of mass. But magically you postulate that the Sun is different it has no wobble indeed the planets around it have no effect whatsoever as the force from the planets is so small? I thought that you were trying to take the scientific position. 😉

About the problem of tides, it was known since ancient times that the major driver was the moon. Every fishermen knew it very well.
It is true that some people have proposed alternative theories, such as Galileo, but these alternative theories were not believed by anybody. Galileo troubles mostly mostly caused by his anomaous theory of tides that even fishermen could disprove at his times. Kepler, instead reasoned correctly basing its theory on actual data and careful observations.

Probably there is a link between earthquakes and climate and aurora and astronomical cycles and ocean current and LOD etc and everything is physically coupled to everything else.
In any case, my paper focuses on the indirect link between mid-latitude aurora historical records and climate cycles and the coerence of these cycles with astronomical cycles. And I show that with these cycle it is possible with a reasonable accuracy to forecast climate oscillations att hedecadal scale. I use only 4-5 cycles, not just one. Also the paper focuses on the physical mechanisms that may cause these climatic oscillations, that is albedo oscillations, read section 7.
The paper is not supposed to address any possible geophysical problem one might think. Nor it addresses Leif’s cospiratory theory (November 11, 2011 at 12:19 am) according to which the aurora record presents a 60-year cycle because somebody (that Leif does not name) put it in.

It is interesting that this is the cycle I found in Iowa tree ring data, and it, by far, appears to be the most important cycle in the data. In an article I wrote (back in the early 90s), I speculated that it might be connected to the Saturn/Jupiter lap period along with the rotation of the sun. i have no idea if the tidal forces on the sun might be sufficient to cause solar variability that could be detected in tree ring data in Iowa, however.
For this cycle to repeat, we should see some poor growing conditions for trees in Iowa into the middle of this decade.

And there is also no 60-yr cycle in the cosmic ray flux during the last 10,000 years: http://www.leif.org/research/FFT-10Be.png

November 11, 2011 8:41 am

Leif, please try to think with an open mind.
The aurora record presents that cycle and we can say that the aurora record has been collected by using as detector the entire Earth in the space. The geomagnetic activity index that you like, which was collected at some specific location on the ground, does not show exactly the same pattern?
So what!
The two observables are not the same thing, evidently.
Why you never try to be a little bit humble and acknowledge that there are several things that you do not understand?

It is clearly useless to discuss with Leif!
The multimillenarian scale temperature and Be reconstructions are too poor to accurately reproduce a 60-year cycle because the data are very sparse: there is one point every several decades. My paper is filled with references where the 60 year cycle is seen in numerous solar-related and climatic records. Unfortunately Leif does not feel the need to read them with an open mind, just as all sophists do.

Massive weaknesses in this paper. The suggested physical mechanism, as presented in this paper, of cosmic rays and clouds is NOT validly or reliably accomplished. Plausibility (IE the mechanisms well-reasoned details) is entirely lacking in the paper. Mechanisms MUST be girthed with plausibility when being thrown into a paper focused on solar/climate cycle matching. In my opinion, Scafetta’s paper is mortally wounded by such a failing.

There’s spatial geometry, so tide tables are fit LOCALLY.
Doesn’t make sense using epicycles to fit GLOBALLY (due to local spatial phase reversals, such as when the jet stream moves from one side of a location to the other).
Circulation is a function of GRADIENTS, not global averages. Too much weighting of speculation towards clouds and not enough towards CIRCULATION.
Change the shape of the temperature gradient only slightly and the land-ocean flow regime is altered. (That’s what atmospheric circulation index (ACI) is all about.) Since land & ocean have strongly contrasted heat capacities, global averages move as a function of nothing more than gradient changes. (Remember COWL?!)
The north-south Y-asymmetry in the geomagnetic field DIFFERS IN SHAPE from the north-south land-ocean asymmetry affecting climate, but the 2 transmissions have a common crank shaft. So beware confounding.
Silly as it may sound – (too much anomaly-think perhaps?)
– here’s what’s being missed:
It matters whether it’s winter or summer and north or south (when Earth samples the solar cycle).
That’s ALL this graph says:
http://wattsupwiththat.files.wordpress.com/2011/10/vaughn4.png
(Since a misunderstanding / misrepresentation keeps coming up: That’s NOT a curve fit.)
It seems people are hoping it’s more complicated, but it’s just asymmetric aliasing changing the shape of gradients.
I STRONGLY advise everyone to read up on the statistical concepts leveraging & Simpson’s Paradox and the spatial analysis concepts “modifiable areal unit problem” & fractal dimension.

As you well know a great deal of the knowledge of the ancients was lost-some through the destruction of the great library of Alexandria, some as the Roman Empire declined.
Some science was rediscovered in the early days of the Moslem empires who had a great regard for Greek knowledge and actively sought it out. Pytheas was perfectly well aware of the moon and its effect on tides, as would fishermen be. I am not disagreeing that it was not scientifically quantified again until Newton, but the knowledge already existed.
“Pytheas on the tides
Pliny reports that “Pytheas of Massalia informs us, that in Britain the tide rises 80 cubits.”[61] The passage does not give enough information to determine which cubit Pliny meant; however, any cubit gives the same general result. If he was reading an early source, the cubit may have been the Cyrenaic cubit, an early Greek cubit, of 463.1 mm, in which case the distance was 37 metres (121 ft). The maximum tidal rise in the Wash, where the tides are highest, is 6.8 metres (22 ft). However, higher tides occur on the west coast – for example 15 metres (49 ft) in the Severn Estuary. One well-circulated but unevidenced answer is that Pytheas is referring to a storm tide.[4]
Matching fragments of Aëtius in pseudo-Plutarch and Stobaeus[62] attribute the flood tides (πλήμμυραι plēmmurai) to the “filling of the moon” (πλήρωσις τῆς σελήνης plērōsis tēs sēlēnēs) and the ebb tides (ἀμπώτιδες amplōtides) to the “lessening” (μείωσις meiōsis). The words are too ambiguous to make an exact determination of Pytheas’ meaning, whether diurnal or spring and neap tides are meant, or whether full and new moons or the half-cycles in which they occur. Different translators take different views.
That daily tides should be caused by full moons and new moons is manifestly wrong, which would be a surprising view in a Greek astronomer and mathematician of the times. He could have meant that spring and neap tides were caused by new and full moons, which is partially correct in that spring tides occur at those times. A gravitational theory (objects fall to the center) existed at the time but Pytheas appears to have meant that the phases themselves were the causes (αἰτίαι aitiai). However imperfect or imperfectly related the viewpoint, Pytheas was the first to associate the tides to the phases of the moon

Nicola,
Perhaps you might explain why FFT does not show a 60 year cycle but MEM does.

November 11, 2011 9:58 am

Dr. Scafetta
a) solar activity (300 year record) has no 60 year cycle
b) the Arctic circle magnetic field, to which auroras are related (400 year reconstruction from the navigation records available, i.e. from shipping logs of magnetic inclination and declination ) has no 60 year cycle
c) the most accurate temperature record available, the CET (350 years long) has no 60 year cycle.
This is not to say there are no natural cycles in the climate records, indeed there are, and they can be loosely correlated to the solar activity, but there is no astronomical 60 year connection.
There is about 50-ish year period in the solar activity, Arctic magnetic events and the CET, this can be linked to the astronomical events as I have shown in here :
http://www.vukcevic.talktalk.net/LFC4.htm
(P1+P2)/2 =107 (half period 53.5 years)
P1-P2 =22 Hale Cycle

@Lief,
I am honestly confused by this discussion. Doesn’t the paper show power spectrums and data clearly demonstrating a 60 year cycle? The data is right there in the paper. So, the question is, what exactly are you refuting?
What needs to be refuted is the source of the data being used to show these 60 year cycles (as are clearly shown in the paper, power spectrum and raw data), or the statistical/mathematical methods employed. The data source itself may be corrupted, or manipulated, analysis applied incorrectly, etc. But just saying there’s no power spectrum showing 60 seems ignorant, since the paper shows that in several ways, clearly.
That’s what confuses me about this discussion. You two are talking past each other, and nothing is getting discussed, from what I see.
I really would like an actual comprehensive discussion on what is going on in this paper, with its data, and such.

Jupiter on the other hand, is big enough to cause the centre of gravity of it and the sun to be somewhere between the centre of the sun and the surface of the sun.

I wish to comment on these two sentences. As for the last one, the moon actually has 1/81 of the mass of the earth. Where you got that 1/6 from is that if you were to stand on a scale on the moon, you would weigh 1/6 as much as on earth. So since the moon averages about 240,000 miles away, the center of mass for the earth-moon system is about 3000 miles from Earth’s center or 1000 miles below the surface of Earth.
As for the first sentence, that is correct. But I just want to add that when several big planets are on the same side as Jupiter, the center of gravity can actually be beyond the surface of the sun.

Vukcevic you need to read my paper and the references that it contains that argue for the 60 year cycle first.
For example, you reference CET. You need to realize that CET is a too local record that may be effected by vocano and local patterns. On the contrary in my paper
A. Mazzarella and N. Scafetta, “Evidences for a quasi 60-year North Atlantic Oscillation since 1700 and its meaning for global climate change,” Theor. Appl. Climatol., DOI 10.1007/s00704-011-0499-4 (2011).
I use a reconstruction of the NAO that includes CET as well as all other available records from europe and a quasi 60 year cycle appears more clearly.
The same can be said for the other records you reference.
Data analysis is a complex matter that requires careful mathematical and physical considerations in particular when proxy models are used with all their errors and ancertenties.
Not all records are equally valid for a specific purpose, not all records show the same things. This is perfectly normal and it is part of the complexity of the problem.
Moreover FFT is the poorest way to calculate the spectrum for a lot of reasons, beginning by the fact that it is discrete.
In any case, if you believe that your analysis is better and you have a better theory, you need just to write a scientific paper and submit it to a science journal. Once it is pubblished we can discuss it.
My above paper focuses on the Aurora records patterns and global temperature patterns, not on other things. And I show that the two records presents the same major frequencies and these major frequencies correspond to major planetary frequencies.
So, I invite you as well as Leif to focus on the actual content of the paper, not on things that the paper was not supposed to address in any details such as what happened in central england or what happened to the sunspots that are only a small subset of the solar and heliosphere dynamics.

The NAO is made up of two components, one has a quasi period of 50+ years, the other one around 70 (but they change a bit if you change length of the data sets), and as result you get (P1+P2)/2. This is also directly reflected in the AMO, so you get 60-65 quoted by various authors.

I never said that the cycle must be exacly 60 years. In dynamical system the things oscillate around limit cycles, So sometime a physical cycle may be larger than 60 year and another time may be smaller than that. This is particularly true if you look at subsystems. In the literature there are a lot of papers arguing for a 50 to 70 year oscillation in mutiple records. My interpretation is that ther exists a dynamical attractor at about 60-year that would explain the finding. This attactor points to Jupiter and Saturn 60-year oscillation.
If you do not like the interpretation, that is fine for me, but does not change my position.

Abstract
The study of the global atmospheric electric circuit has advanced dramatically in the past 50 years. Large advances have been made in the areas of lightning and thunderstorm research, as related to the global circuit. We now have satellites looking down on the Earth continuously, supplying information on the temporal and spatial variability of lightning and thunderstorms. Thunderstorms are electric current generators, which drive electric currents up through the conducting atmosphere. They maintain the ionosphere at a potential of ∼+250 kV with respect to the Earth’s surface. The global electric circuit is completed by currents flowing through the fair weather atmosphere, remote from thunderstorms, and by transient currents due to negative cloud-to-ground lightning discharges. The time constant of the circuit, , demonstrates that thunderstorms must occur continually to maintain the fair weather electric field. New discoveries have been made in the field of sprites, elves and blue jets, which may have a direct impact on the global circuit. Our knowledge of the global electric circuit modulated by solar effects has improved. Changes to the global circuit are associated with changes of conductivity linked with the time-varying presence of energetic charged particles, and the solar wind may influence the global electric circuit by inferred effects on cloud microphysics, temperature, and dynamics in the troposphere. We now have a better understanding of how the conductivity of the atmosphere is influenced by aerosols, and how this impacts our measurements of the fair-weather global circuit. The global atmospheric electric circuit is also beginning to be recognised by some climate researchers as a useful tool with which to study and monitor the Earth’s changing climate.

I wrote this article that appeared at Climate etc
http://judithcurry.com/2011/06/27/unknown-and-uncertain-sea-surface-temperatures/
and subsequently had a long series of email exchanges with John Kennedy. The manner in which SSTs were collected are highly unscientific and have little merit as a serious temperature record . Dr Judith Curry is also of the opinion that anything prior to around 1960 is seriously flawed.
I do not think they have a place in any scientific paper due to their huge margin of error. Sorry.
Incidentally I am sure that you are aware that CET is very well correlated as a significant proxy for Northern Hemisphere temperatures? It would be very interersting to see the results of your study (which I thought verygood) using CET but excluding SST’s to 1850.

November 11, 2011 12:46 pm

I didn’t see a section in the paper discussing the aurora data itself. While I don’t necessarily disagree that aurora strength is a decent proxy for solar magnetic field strength, and I don’t necessarily disagree that solar magnetic field strength can influence albedo, what I would point out is that the relationship between climate and aurora record works in both directions.
Here’s what I mean. I grew up at 43N latitude. That’s a mid-latitude and I don’t ever really recall seeing an aurora. They’re rare events in mid-latitudes. I’m sure there were some and if I’d been diligent I might have spotted some. But here’s the thing – auroras can only be seen on clear nights, which has foiled my viewing more often than not. So the very clouds that are purportedly regulated by the aurora (or the solar activity for which auroras are a proxy) themselves effect the ability to see the aurora. So not only might auroras influence cloud cover, cloud cover influences the ability to observe auroras! The influence might work in both directions is what I’m saying.
Moreover, in looking at what little is portrayed of the aurora record in the paper I notice the graph of them, figure 2B, is cut off at the year 1966.
It would appear that the last 45 years of aurora data is not taken into account in this study. That seems like a pretty big omission. Hide the decline kind of stuff to put it bluntly. A suspicious person might think the correlation fell apart after 1966…

I am honestly confused by this discussion. Doesn’t the paper show power spectrums and data clearly demonstrating a 60 year cycle? The data is right there in the paper. So, the question is, what exactly are you refuting?
A very powerful ingredient of the scientific method is replication. If a claim cannot be replicated, preferably with different data and different methods, it suffers. Just cranking through the same data the same way is not replication [as one always assumes that the claim was made in good faith by competent people – unless evidence to the contrary]. If an effect is clear in the data, even the crudest method [such as FFT, which does in my esamples find the semiannual peak and the solar cycle peak and a 60-yr peak if I put one in] will show it. If it takes extensive massaging and tweaking to ferret out an effect, it is plausible that it is not there in the first place.
So, I use independent data of geomagnetic activity [much better than auroral counts – which for example show a clear lunar cycle, because they are harder to see at full moon], cosmic ray data, sunspot numbers, and even climate, and show that none of these show any 60-year cycle over long enough time periods [centuries]. Thus replication fails and the claim fails.

Great. Give us a link when your refutation is peer reviewed and published. Personally I don’t think you’ve compared apples to apples and it won’t be accepted but that’s just me. I think you first have to establish a link between mid-latitude auroras and the hodge-podge of other proxies you mention. Scafetta’s discovery is a correlation between mid-latitude auroras which may or may not correlate well with those other proxies. Apples and oranges IMO. At least for now.

November 11, 2011 1:31 pm

Leif, read the paper and the references!
Your way to analyze the data is just naive. You need to think more deeply.
Tonyb.
I may agree about the fact that the composite of the tempeature data may have problems, but that is what we have.
If Judith Curry believes that the data before 1960 are seriously flawed she should have said it in her BEST papers and she should have limited her BEST reconstruction to post 1960 which is something that she did not.
In the paper I analyze several records, not just the Kennedy record, including both HadSST2 and HadSST3 records.
Moreover, I have analyzed all available temperature records from all groups and from all regions of the Earth (Norh and South, Land and Ocean) and the results are approximately the same. Those records present major frequency peaks at about 9, 10-10.5, 20-21 and 60-62 year.
Although these records might have errors, their error is likely less than the error of using CET as a proxy for the global temperature.
About CET you clealy see maxima around 1940 and 2000. Then the 60-year cycle predicts a maximum in 1880s which is seen in the global temperature data. However CET does see a cooling instead of a warming. This is probably because in the 1880s there was a huge Krakatoa volcano eruption that might have caused a significant cooling in England and disrupted the pattern. Then the 60 year cycle predicts a maximum around 1820 and a minimum around 1790 and these are there. Before 1790 CET is very poor, and the patterns are less clear. So a 60-year cycle may be present in CET although it may be disrupted by some volcano activity in particular in the 1880s.

the records are limited because those aurora were in the past seen and recorded mostly in the cities. After 1900 street light has made very difficult to see these auroras and mobody cared to report the aurora as seen in the country-side.
You argument with the clous is not valid. More auroras were seen during the multidecadal cold periods, that is the most cloudy ones. Moreover, there aurora are not observed in just one location but in a very large region

@Hoffman
Adding insult to injury the force of gravity falls off as the inverse square of the distance so the moon, at 1% the mass of the earth at a distance of 250,000 miles has approximately 400 million times as much gravitational pull on the earth as Jupiter does on the sun with Jupiter being about 2000 times as distant and 10 times less relative mass. Not going to be much of a tide on the sun from Jupiter. Maybe a micrometer? That’s why detecting planets around other stars is so difficult. They really need a planet as big Jupiter orbiting as close as Mercury to detect the wobble caused by the offset in barycenter. Either that or they need very long observation times to pull smaller deflections out of the noise.

@Leif,
“A very powerful ingredient of the scientific method is replication. If a claim cannot be replicated, preferably with different data and different methods, it suffers. Just cranking through the same data the same way is not replication [as one always assumes that the claim was made in good faith by competent people – unless evidence to the contrary].”
I absolutely agree, as you make a wonderful point. However, there are many aspects of science where new techniques are made to allow observations or analysis of data no other techniques can do. If the techniques are sound (as no one has really presented an argument or evidence that they are not, so far), and the base data is showing us something, we still have to address why this data, why these techniques; we can’t simply dismiss. Even if other methods cannot replicate, that the techniques and data used in the paper can be replicated means it is science and fit for our consideration.
And I guess that’s really the issue for me. What I’m saying does not, in any way, detract from what you said–as you are completely right. The fact other methods are not supplying supporting data to this hypothesis weakens it–we aren’t seeing anything yet that provides it additional strength. Artifacts can happen (maybe something about the aurora and particular temperature data creates this artifact, but no one has said or argued as such), spurious results do occur, and multiple lines of evidence are in the end required for any hypothesis to make it to the level of theory. But it all doesn’t -disprove- the hypothesis either. It’s still valid from what I see. Absence of evidence is not the evidence of absence, and all that.
There are references though, and mounting data that shows this 60 year phenomenon from what I’ve seen, but I can make little sense of it. Hence my interest in your points and discussion.

Frankly, even when I agree with you on something, which I frequently do, I’d rather not voice my support because of your bullying, ad hominem attacks, foul mouth and ignorant attitude.

“the records are limited because those aurora were in the past seen and recorded mostly in the cities. After 1900 street light has made very difficult to see these auroras and mobody cared to report the aurora as seen in the country-side.”
WTF? We’re talking 1966 not 1666. In 1966, incredible as it may seem to boys your age, we had telephones, radio, AND television not to mention hundreds of millions of people living in mid-northern latitudes away from streetlights. No aurora visible in mid-latitudes went unreported between 1966 and present. The excuse you just pulled out of your backside is unacceptable and absurd on the face of it. You’re either lazy or hiding something. Either way it’s a FAIL.
“You argument with the clous is not valid. More auroras were seen during the multidecadal cold periods, that is the most cloudy ones.”
Really? I thought it was common knowledge that clear nights are the cold ones and cloudy nights are the warm ones. I’m afraid that’s another FAIL. Three strikes and you’re out. Don’t try bullshitting me a third time.
” Moreover, there aurora are not observed in just one location but in a very large region.”
Which is bloody well why no aurora could possibly have been missed after 1966 because so very much of the Northern Hemisphere was populated, even in rural locations, with instantaneous communications. The number of astronomical observatories on mountaintops alone by 1966 makes your premise incredibly poorly thought out. I hope the rest of your work isn’t as shallow but now I wonder.

So, going back to davidmhoffer 8:28pm
You think my answer was wrong? Unfortunately your question was not precise – you did not ask me to compare the force the earth exerts on me with the force I exert on the earth. You asked to to compare “the effect”. You are perfectly correct in that the forces are equal, but unfortunately I chose, recognising the ambiguity, to compare the magnitude of a different effect, one which gives a better illustration of the importance of size and mass. Which one? – the gravitational potential which determines the accelerations.
Which means that the rest of your somewhat pompous lecture is irrelevant, or worse. I never stated that I thought the distance between myself and the earth was zero (read it more carefully),
and I am well aware of center-of-mass motion. Indeed I seem to have a better idea of where the barycenter of the solar system is than you do, as I know that it changes position slowly and it is sometimes within the structure of the sun and sometimes outside.
So to tides – two problems with your comments here. Firstly the effect of Jupiter does not “have years to build up” because sun rotates! In fact the rotation is different for different regions of the sun, being about 25 days at the equator and 36 at the poles. It is this differential rotation that is though to cause the very strong magnetic fields which cause sun spots, according to what is known as the Babcock model. And people think that the magnetic field of Jupiter 800 million kilometers away can have an effect on something like that…
The other mistake you made was to get your magnitudes wrong – if you get the right masses and distances you can work out that the ‘tides” on the sun caused by the planets are less than 1mm. If you think that could have an effect then here is a reference to a paper, 35 years old but still unchallenged http://articles.adsabs.harvard.edu//full/1975SoPh…42..529C/0000531.000.html
Oh, and it is the gravitational accelerations that cause the tides…

IR doesn’t penetrate water during a rainstorm. It’s still water and it’s still opaque to IR. You have quite the tendency to rewrite history. You were never able to produce any evidence whatsoever that downwelling far infrared can slow down the rate of heat loss from the ocean.

You didn’t get an impressive score on the verbal part of the SAT, didja?
Well they didn’t have SAT’s when I was at school, and I think you mean the written part.
But let’s try analysing my opening sentence “Without a physical mechanism, this is astrology not science”
So firstly what does the “this” refer to – well clearly it is this particular paper, not any other paper, not a whole field of science, just this one.
Now “without a physical mechanism” , what is that – well the paper notices a correlation, and suggests a mechanism. But I am saying the mechanism is implausible i.e it is not a physical mechanism i.e not one founded surely in physics.
So to “astrology” – well if it is not a mechanism which is securely founded in physics, then the paper is suggesting a influence of the planetary motions without a physical origin – and what is that – well it is astrology, not science.
“science” – curve fitting is not science.
So you can disagree with my point about physically plausible mechanisms if you want – so why don’t you try to explain what you think their mechanism is, and whether it is sensible, and if you cannot, then say what you description of the paper is.

That link to the Scripps paper is awesome. How the heck did they ever get it published when it proposes a natural cycle of rapid cooling happening every 1800 years when tidal force from the moon is strongest at the equator and then maximizes mixing of cold deep water with warm shallow water.
I had no idea that tides had any periodicity longer than the 9 and 18 year cycles caused by lunar orbital precession. But I guess there must be quite a few others now that I think about it. The earth’s axis precesses in a cycle of 26,000 thousand years so there’s going to be a change in tides due to that as well.
Thanks for the link. And thanks for the laugh “Yes”. Good one.

“Now you are emphasizing that the effect of gravitational fields are extremely small. But how much force is necessary to keep a planet with a mass of 1.9 x 1027 kg in orbit? The continual velocity change requires a continual acceleration toward the Sun. You think that this requires only an infinitesimally small force?”
No I think it needs the acceleration due to the gravitational potential of an object 1000 times as massive.
“Stars like the Sun are being identified as having planets around them by the fact that the stars ‘wobble’ due to the orbit of their planets around them. Or more correctly the stars and their planets are orbiting their barycenter – their center of mass. But magically you postulate that the Sun is different it has no wobble indeed the planets around it have no effect whatsoever as the force from the planets is so small? I thought that you were trying to take the scientific position. ”
OK so since various people have mentioned it, I think it is time to think about what this wobble means (I have never denied its existence by the way). Lets try a thought experiment, what physics calls a “to first approximation” scenario, which is useful for working out the most important features, and then asking how the real system differs.
So take a solar system with just a star and a heavy planet. Now imagine a model which is just two weights connected by a rod. Find the balance point, which is the center of mass. Let the two object rotate about that point. If you are and observer outside the system what do you see? Well the “star” is sometime one side of the center of mass, sometimes the other, so to an outside observer it appears to “wobble” in its position. But here’s the important bit – that wobble has no effect on the properties of the star because all the distances are constant So thats the “to first approximation” – the wobble is simply the rotation about the center of mass, and has no effect on the properties of the star. Now the real system – because the planet has an elliptical rather than a circular orbit, its distance varies slightly. It is only this variation which might cause a change in the properties of the star. Jupiter’s distance changes by about 4% from maximum to minimum – so the question is, can that modulation have a significant effect? I say no.

November 11, 2011 3:36 pm

Ooops! My apologies. I goofed above with reference to the center of gravity between Jupiter and the sun. It turns out that if only the sun and Jupiter existed in their present orbits, the center of gravity is actually outside the surface of the sun. Here are the important numbers:
Mass of the sun = 1.99 x 10^30 kg.
Mass of Jupiter = 1.90 x 10^27 kg.
Mean orbital radius of Jupiter = 7.78 x 10^11 m.
So the center of mass between Jupiter and the sun is
7.78 x 10^11 m x 1.90 x 10^27 kg/1.99 x 10^30 kg = 7.43 x 10^8 m.
However the sun’s equatorial radius is 6.96 x 10^8 m. This, of course, is less than the center of mass for Jupiter and the sun. The other planets will either add or subtract to this center of mass, depending on their location relative to Jupiter.

November 11, 2011 3:40 pm

jimmy_the_dalek;
good points.
I’d forgotten the rotation of the sun, but my point still stands. The moon raises quite the tide in a 24 hour cycle. Jupiter has weeks. Only one millimeter? Let’s take your word for it at this point. While the earth is covered mostly in water, it is a fairly thin layer compared to the diameter of the planet as a whole. The sun on the other hand is molten (though it may have a core of some sort that is different for a variety of reasons) but the fact of the matter is that gravitational pull from something the size of Jupiter shifts things inside the sun as well as raising a tide. As Werner Brozek pointed out, when the planets aligne, the centre of mass actually lies outside of the surface of the sun. That’s quite the wobble to impose on something as big as the sun and at the same time claim that variations in orbit don’t affect climate on earth because it is “impossible”. Consider also that if Jupiter and Saturn can raise tides on the sun and cause it to wobble about itself in space, that they also affect the orbit of the earth. For all we know, the fluctuations induced in earth’s orbit are the larger factor than changes induced in the sun, or perhaps they are additive, or perhaps they work against each other. We need not know the answer to those questions in order to observe that specific alignments of the planets and moon in relation to the earth correlate to climactic conditions. If so, let us investigate and discover the reasons why, or if it is a coincidence.
If coincidence, it is a really really BIG coincidence. But impossible? Hardly.

So, pulling the trigger on a gun cannot be the cause of a murder, because the four or five pounds of force it takes to pull a trigger is not of deadly magnitude?
Well you have just put a major positive feedback in there – pulling the trigger initiates a chemical reaction. I hope you are not going to say the earth’s climate system has major positive feedbacks, because around here people tend to shout at you for that.
The period and magnitude of the ocean tides changes a little from cycle to cycle, therefore the moon, with its precise orbit, cannot be the origin of tides?
The amplitude changes, which is entirely explainable as due to the positions of moon, sun and their distances from the earth. I do not think there are major changes in the period – do you have information to the contrary?

I’ve pointed out the confounding before, but many accidentally misinterpret and others deliberately misrepresent. The way the game goes for obfuscators seems to be something like: If I say climate drives EOP (Earth Orientation Parameters), they claim I said EOP drive climate. If I say lunisolar cycles are detectable in the QBO, they claim I said Jupiter drives terrestrial global average temperatures. Something like that.

@ Dave Springer
The aurora catalog was not compiled by me. The appropriate reference are in the paper: read them or write to those authors for explanation. The above is the exaplantion I heard from people expert in those records. The record that ends in 1966 refers to the Faroes’ Island that are located North England which were quite more isolated than the central and north Europe where it was becoming increasingly difficult to see mid-latitude aurora and people lost interest in emphasizing them as they were doing in the past.
@ Ged
well written!
It is very inappropriate in science to dismiss a finding based on specific records simply claiming that different records do not show the same identical patterns. Each record is produced by its own physics and each record stresses the patterns compatible with its own physics. It is perfectly normal that different records present different patterns. Thus, a comparison may be made only after that the physical link between two records is established.
So what people do is to look for those records and thecniques that may reveal a physical coupling mechanism that other records may not reveal as well or as clearly.
If all records would present the same identical patterns everything would be linearly coupled to everything else and no errors would exist, which is not the case in natural systems.
The problem with Leif is that he does not appear to understand basic phylosophy or how science of complex systems really works. It is like as if I say that today in NY it is raining, and Leif responds that I am wrong because he looked at the weather in CT and it was not raining so he could not replicate my claim! Does such a reasoning make any sense to anybody?
As Ged understood, “There are references though, and mounting data that shows this 60 year phenomenon”. In figure 3 of my paper I show some of these records, but many others are present in the references.
Not all records present the same identical patterns. So what? the correct question is to understand why. Is it because the chosen data are very local? is it because the data are disrupted by something else? is it because there are errors in the measurments? is it because the data are mostly sensitive to something else? is it because the data are just different? is it because of complex non linear couplings? etc.
Moreover, in Figure 11 I buid a model based on these cycles and show that the relative climate patterns can be forecasted with a precision far above the IPCC models.
So, Leif just need to be more open minded and stop with his hand waving logic that proves nothing about my paper and much about his behavior. If he does not like my theory he is very welcome to propose an alternative theory and shows that it works better than mine!
For example, does Leif know of any IPCC climate model that has been able to “forecast” the climate oscillations from 1950 to 2010 and backward from 1850 to 1950 as I show in my figure 11B? Please, name one!
@ jimmi_the_dalek:
in the paper I do not do just curve fitting. I show that the harmonic model based on those specific astronomical cycles seen inthe aurora record from 1700 to 1900, for example, is able to forecast the climate oscillations from 1950 to 2010. You may fit a record with an infinity of curves that you like, but if the functions that you use have nothing to do with the dynamics of the system, that same model would immediately fail any forecasting.
Your definition of science (a theory must be supported by a mechanism, if not it is astrology) has nothing to do with science but with methaphysics. In science a theory should be able to agree with the data and reproduce and forecast them. The ultimate mechanisms may be simply unknown. All science of complexity is based on the assumptions that a macroscopic system can be described by using empirical models which do not need to be explicitly backed by microscopic physical explanations. And the ultimate mechanisms explaining the fundaments of physics are unknown (what is the mechanisms that explain gravity, what is the mechanisms that explain the time contraction in special relativity? etc).

Yes, you can google that in a few seconds although I already knew it. The center of mass just clears the surface. However, of the raduis sun is about 700,000 kilometers and it orbits the center of mass once every 12 years, so Jupiter causes the sun to wobble at a speed of 0.2 meters per second. So when trying to detect planets around another star we have to be able to see a red/blue shift in the star’s light (given it’s exactly edge-on to us) of about a half-meter per second. Light travels at 300,000,000 meters per second so this frequency shift represents about two parts per billion and it would take twelve years to see one full cycle of the shift. This gives you some idea of why it’s so difficult to detect planets around other stars. Now imagine there are multiple planets, which is usually the case, mucking up the frequency shift as they all orbit with different periods. It’s quite the sticky wicket and there’s no small amount of controversy except in the cases of one or two gas giants in very close orbits.

You fail to take into account the sun’s rotational period vs. the orbital period about the sun/jupiter barycenter. The latter I happen to know is 12 years. I don’t think the sun and Jupiter are tidally locked like the earth and the moon so let me look up the former… that’s about 25 days. So Jupiter is going to produce some tides on the sun. You and I would both be guessing if we said we knew what effect those tides might have although I’d tend to agree it’s going to be pretty minimal given the strength of Jupiter’s gravity on the sun is millions of times weaker than the moon’s pull on the earth.
By the way, you WERE wrong about calling the OP astrology just because there’s no mechanism. A correlation without a known cause is a mystery. Science is full of mysteries. In fact science is all about mysteries! If there were no mysteries there would be nothing left to explain and nothing for science to do. Engineers could then take over (as if we don’t rule the roost already… lol) completely. Astrology on the other hand lacks mechanism AND correlation. If there’s no correlation there’s nothing to explain. It isn’t science until you can at least come up with some effect that needs explaining.

Linkages between solar activity, climate predictability and water resource development*
http://www.lavoisier.com.au/articles/greenhouse-science/solar-cycles/Alexanderetal2007.pdf
This study is based on the numerical analysis of the properties of routinely observed
hydrometeorological data which in South Africa alone is collected at a rate of more than
half a million station days per year, with some records approaching 100 continuous years
in length. The analysis of this data demonstrates an unequivocal synchronous linkage
between these processes in South Africa and elsewhere, and solar activity. It is also shown with a high degree of assurance that there is a synchronous linkage between the statistically significant, 21-year periodicity in these processes and the acceleration and deceleration of the sun as it moves through galactic space.

…I use independent data of geomagnetic activity, … cosmic ray data, sunspot numbers, and even climate, and show that none of these show any 60-year cycle over long enough time periods [centuries]. Thus replication fails and the claim fails.

Rubbish. Scafetta has already showed six different indices in his paper which all show with stunning clarity the formative presence of a 60-year cycle: PDO, AMO, auroras, monsoons, meteorites, and global temperatures (detrended etc). Thus replication has already succeeded so the claim holds so far. The correlations are highly evocative, I don’t know how to quantify them statistically but visually they shout. Thus the likelihood increases that your apparent non-correlations may have other factors at work, that do not disprove the presence of a 60-year cycle.

Here’s the bottom line Nicola. You have, at best, 120 years of semi-accurate temperature record to work with where the past 30 years (the satellite era) are by far the most accurate, precise, and the only part with anything that can be called “global” in coverage without snickering.
Then, with your aurora data ending 45 years before the temperature data ends, you have a period of 85 years where you can look at both records for correlation. Now then, you’re trying to peddle a correlationon a 60-year cycle when you have only 1.3 cycles to compare. A correlation with a sample size of 1.3 isn’t statistically sound. In order to strengthen this you need to get extend the work of others and generate the most recent 45 years of aurora data and make it reasonably comparable to the other two. This will require some effort on your part, kiddo.
Here’s what I would suggest. Find some small towns at a similar latitude with similar weather patterns similarly remote from any light pollution of larger cities and comb the local newspaper for aurora sightings. These rarely go unreported. Or let this paper of yours be consigned to insignificance with no citations and stay an assistant adjunct professor (what is that, anyway, one pay grade above a lecturer?) the rest of your life.

If there were no mysteries there would be nothing left to explain and nothing for science to do. Engineers could then take over (as if we don’t rule the roost already… lol) completely.”
Here the real difference is between those who understand what sciene is about (there are correlations with unexplained misteries that need to be explained) and those who mistake science for engineering (the science is settled, no need to look forward).
In climate science the major problem is that many people do not understand the difference between “science” and “engineering” any more. We have computer climate modellers, who properly speaking are engineers and not scientists, who go around claiming to be “scientists” and that the “science is settled”, and everytime a real scientist observes that the science is not settled because the data show specific patterns that the climate models do not explain, then the climate modellers start to deny the data and accuse the scientist of astrology just because he did not provide them a full and complete theory that they can implement in their models.
Science does not start with a complete theory of everything. That is the ultimate goal of science, not its starting point! This is an important point for those that really want to understand science.

Here’s what I would suggest. Find some small towns at a similar latitude with similar weather patterns similarly remote from any light pollution of larger cities and comb the local newspaper for aurora sightings. These rarely go unreported. >>>
If you had grown up in such a town (which I did, latitude 50) you’d be aware that auroras are so common that only a very intense display would ever make the local paper, and often not even then. Such a methodology would be complete hit and miss, and the exact opposite of the scientific precision which you demand.

“…And all the solar system barycenter chattering you hear is also confounded with things closer to home:”
I hear ya. Most people don’t know that gravitational problems involving more than two bodies are exceedingly difficult unless one of the bodies has an insignificant mass like an Apollo capsule heading to the moon or a deep space probe doing flybys of inner planets to generate delta-v. For n-body problems where n is greater than 3 only increasingly imprecise approximations are possible. Pretty much the same thing holds true for quantum mechanics and greater than two particles. Interestingly, Voyagers 1 and 2 aren’t in the predicted positions after decades of travel and reaching the outskirts of the solar system. One of them, I forget which, is about to penetrate the heliosphere shock-wave and reach into true interstellar space. There’s some fun arguments about why they aren’t where they’re supposed to be. Also, interestingly enough, their radiothermal power supply radioisotope fuel appears to have a half-life that is changing with distance from the sun. There’s some fun with that too. There’s also some weirdnesses with radioactive decay rates on earth changing with the seasons which also correlates with distance from the sun. Some pretty basic things in physics, the constancy of radioactive decay rates and the gravitational constant, are under assault from increasingly accurate observations. There’s a LOT of resistance to that, let me tell you. The list of excuses and excusers claiming the observations are somehow flawed is long, distinguished, and all really contrived if you axe me.

Lucy Skywalker, thank you for your comment and for having read my paper: a thing that Leif and other critics did not do.
I showed six different indices plus two planetary records (speed of the sun relative to the barycenter and tidal elongation at the Earth orbits) (which makes eight indexes explicitly shown in the figures).
Plus in my 2010 paper I study the global north temperature, global south temperature, global ocean temperature, global ocean north temperature, global ocean south temperature, global land temperature, global land north temperature, global land south temperature, which make other eight indexes.
Plus in my other 2011 paper with Mazzarella I show the same cycle in the NAO,and LOD, which makes other two indexes explicitly shown.
Total 6+2+8+2=18 indexes
plus I reference numerous other papers that enphasize the existence of a quasi 60-year cycle in the climate and solar records for centuries and millenia.

“Then, with your aurora data ending 45 years before the temperature data ends, you have a period of 85 years where you can look at both records for correlation. Now then, you’re trying to peddle a correlationon a 60-year cycle when you have only 1.3 cycles to compare. A correlation with a sample size of 1.3 isn’t statistically sound.e, you have missed the point of the paper. ”

I got a 94% on the civics test. Two questions wrong.
I got the question about the Gettysburg Address wrong. I thought the phrase “government of the people, by the people, for the people” came out of the Constitution but it was Lincoln’s Gettysburg Address. How embarrassing! But in my defense I only took “American History to 1850” in college and that was enough to satisfy the general-education requirement. I haven’t seen the Gettysburg address since probably 1966 (fifth grade). I’ve read the constitution and all the amendments at least several times in the last 10 years though so it’s a weak excuse.
But I’d argue there were two correct answers to the only other question I missed and that was “If government tax revenue equals government spending which of the following is true”
1) there is no government debt
2) wrong answer
3) wrong answer
4) the average taxes a person pays is equal to average government spending per person
I believe both these responses are correct. I chose #1 and that was deemed incorrect. I considered which answer to choose for at least 30 seconds (an eternity for me) and couldn’t decide if one was superior to the other so I picked the one that seemed to better follow the political bias (conservative) of the person who formulated the test.

“If you had grown up in such a town (which I did, latitude 50) you’d be aware that auroras are so common that only a very intense display would ever make the local paper, and often not even then. Such a methodology would be complete hit and miss, and the exact opposite of the scientific precision which you demand.”
You just can’t stop digging your hole deeper, can you? Amazing.
If you’d read the paper that Scafetta referenced you’d know that they were only reporting an average of maybe 5 sightings per year. I didn’t count them all and take an average but that’s accurate enough.
ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/AURORAE/aurorae.dat.rev
Surely some small observatory in some mid-latitude location where auroras can only be seen several times per year has a record from 1966 through today. The actual number they record per year doesn’t really matter much as it’s only the change from year to year that is of interest but it would be best to stick with about the same number as reported in the other catalogs for consistency as we want to try to match the minumum intensity level (apples to apples) when moving from one data source to another.
If acquiring the data for non-trivial scientific research was easy anybody could do it. I specifically told Scafetta it might require some effort on his part and wondered whether he’s just lazy or he’s hiding something. I won’t be the only one wondering about that. It’s a pretty friggin’ glaring thing to cut off a data set for a commonly observed astronomical event in 1966.
What would you think about a global warming claim where they lopped off the temperature data in 1966?
Oh wait, we already know the answer to that. That’s what the climategate emails revealed. They chopped off the tree ring data (pun intended) 20 years early, circa 1960, and stitched in the instrument record from that point forward because the tree ring data went “off message” at that point which meant, if they’d included it, it would have impeached the credibility of the prior years of tree ring data . The skeptics screamed bloody murder when they found out.
Well, Hoffman, I don’t like double standards and if I protest something an AGW pundit did with the data I’m going to hold an AGW skeptic to the same standard. Write that down. It’s called intellectual honesty. You might be an intellectual in your next life and need to know that.
What Scafetta did in this paper was plug some easily located numbers into a statistical analysis program (which is pretty much all he’s ever done in his short academic career), found some interesting correlations, produced some graphs, and imagined some mechanisms to explain them. Unfortunately the key data set, aurora frequency, leaves a lot to be desired both in quality and number of years that can be compared with global temperature data.
Now as for you I strongly urge you to heed this sage advice:

Scafetta found some valid correlations between climate data and astronomical observations. Or at least they appear valid at first blush but I do have my doubts about the sufficiency of the aurora data after a bit more scrutiny.

“If you’d read the paper that Scafetta referenced you’d know that they were only reporting an average of maybe 5 sightings per year.”
Sorry Dave, you are not understanding the issue,
The record that I use since 1700 contains up to 140 events per year.
Look at figure 1B in my paper, it is quite clear. The record before 1700 is quite incomplete so I did not use it. After 1900 it has also become so incomplete that the record stopped to be collected.
You are not understanding these data. The data are likely accurate enougth between 1700 to 1900, and for the Faroes up to 1966.
From 1700 to 1900 there was a great interest of the people in recording these data in the newspapers. Before 1700 there were not many newpapers around not much interest (which started likely with Newton) and after 1900 the interest collapsed in Europe also because it was getting harder to see these aurora from the bright cities.
You should understand that the people that collected these aurora data were professionists, not idiots. They knew what they were doing. They compared several sources to determine the great auroras, they did not get the data from just one town.
Moreover, you are not understanding the tecnique of analisis which is based of frequencies estimates, not on the actual amplitudes. To have a consistent record for frequency estimates you just need that the data are collected in some similar standard way, which is what was happening from 1700 to 1900, and for the Faroes up to about 1966.
The two records of auroras that I analyze contain common major peaks of frequencies such as the 10, 20 and the 60 year cycles, see figure 4. The same peaks are found for the temperature. Moreover the 60-year cycles data back to 1700 in proxy models as I show in Figure 3
The probability that everything coincide by coincidence is quite slim. Try it by yourself. Take two random sequences and ckeck whether they contain the same frequencies and are correlated like the records that I used in my paper.
In any case, if you believe that you understand auroras records better than the people that have collected them, you are very welcome to visit several towns around in the Us, in Europe and in Russia and look at the their newspapers if they have it, collect your better catalog of great aurora record and then send the record to me.
In my opinion these records have a very high quality compared to several other records that we have since 1700, and it is the only record that we have that refers to “direct observations” of the electric properties of the space and upper atmosphere since 1700, and the dates are exact. So, it is far above to any kind of ground based “proxy” model despite what Leif claims.
The scientific quality of these aurora records is probably far above for geografical estension, for time continuity, for number of people indirectly invoved in the direct measurements (several hundred thousands, perhaps millions people just looking at the sky) and for timing and for number of written records than many other records we have, including the CET records.
I know that you would like to have “perfect” and “infinite” data, but in geophysics we get what we get. We cannot go back in time and repeat the observations in an experimentally controlled way. This is part of the complexity of the problem. We need to put together pieces of informations from multiple records which may be incomplete and filled with uncontrolled uncertenties.

Thanks for the post on this paper but I must say I find the response from some of the contributors a bit silly.
The paper is another very useful contribution and the periodicities support work such as “Influence of Zodiac Dust on the Earth’s Climate” by Victor Ermakov, Victor Okhlopkov, and Yuri Stozhkov as well as the other work referred to. Different or related mechanism but still related to cloud formation.
I find it utterly ludicrous that when analysing the climate of a spinning planet with an orbiting moon which in turn orbit a star in company with other planets and other material in the solar system and noting a whole series of periodicities in major planetary climatic/weather systems ( ENSO etc) that one would not start with the assumption of cyclical patterns influenced by the solar system generally ( considering the range of possible direct and indirect mechanisms) and only stop when you could not find any. The 60 odd year cycle is plain to see in the instrument temperature record as is the 1-11 year cycle in smoothed data so a Fourier or similar analysis is entirely warranted. Given the awareness of the 11 and 22 year solar cycles otherwise from sunspot and other direct solar observations / measurements I just wonder who the “deniers” are. I am reminded of that song by Dire Straits exhorting the listener to remember that when pointing a finger there are three more fingers pointing back at you.
But then I am an engineer not a scientist, WTF would I know or understand?

The aurora record presents that cycle and we can say that the aurora record has been collected by using as detector the entire Earth in the space. The geomagnetic activity index that you like, which was collected at some specific location on the ground, does not show exactly the same pattern?
The geomagnetic record is a global average of many stations all over the world.
The two observables are not the same thing, evidently.
We have a good understanding of both and they are just two sides of the same thing. Invariably [that is every single time] when you have a mid-latitude aurora you also have a strong magnetic disturbance, as has been known since the 1750s [slides 3-4 of http://www.leif.org/research/H02-FRI-O1430-0550.pdf ]. If there had been an auroral 60-yr cycle the last 170 years, there would also had been a magnetic activity cycle of 60 years, and there isn’t. This is evidence enough against your claim.
The sunspot number (sampled every day) does not have a 60-yr cycle. Your ideas about the magnetosphere as expressed in the paper [which I have read, of course] are just mush and contradicted by the data. Some reading up on that might be helpful to you. Amazing the reviewer didn’t take you to task on this. Tidal effects are minute [less than a millimeter] and cannot have any effect, and you forget that the Sun is rotating so a tidal bulge would roll over a given location every 13 days just as the tidal bulge caused by our Moon has a 12.5 hour period.

November 11, 2011 11:41 pm

Doesn’t that 60 year or so climate cycle result from oceanic variability rather than solar variability ?
Specifically the phase changes of the Pacific Multidecadal Oascillation (not PDO as Bob Tisdale keeps reminding us) whereby for about 30 years El Nino events dominate over La Nina and then for the next 30 years or so La Nina dominates over El Nino.
In order to link solar events to that phenomenon it is necessary to find a causative mechanism but I don’t see one on such a short timescale.
However on a 500 to 1000 year timescale as from MWP to LIA to date I do see a connection whereby slow changes in average solar activity across multiple solar cycles do seem to alter the net balance between El Nino and La Nina over successive 60 year oceanic cycles.That leads to the upward ‘stepping’ in tropospheric temperatures from one oceanic cycle to the next that has been observed ver the last 150 years.Presumably there was a similar downward stepping from MWP to LIA.
Solar induced loudiness and albedo changes arising from latitudinal climate zone shifting is my favoured explanation for trhat rather than cosmic rays.
To get a good solar/astronomic link to the 60 year timescale we need much better correlations than we have at present but the aurora data is a helpful move in the right direction.
Leif’s negativity is fine as a tool to test the data and hypotheses but I think there is more to it than he currently accepts.

November 12, 2011 12:17 am

Since cosmic rays were part of the mechanism proposed [and also is a measure of solar activity] it would be a crucial test of Scafetta’s ideas simply to plot his modulation function P1(t) vs cosmic rays as given by the 10Be record. We have a nice record from McCracken and Beer [Long-term changes in the cosmic ray intensity at Earth, 1428-2005, McCracken, K. G.; Beer, J., Journal of Geophysical Research, Volume 112, Issue A10, CiteID A10101, 2007]. So here is the result: http://www.leif.org/research/Scafetta-Function-vs-Cosmic-Rays.png [the curves are on arbitrary scales and offset in order to make the comparison easier]. R^2 for a correlation is very small 0.06 and is not considered significant, but it is also evident just by looking at the curves that there is no correlation and no common 60-yr cycle. Again FAIL.

My negativity comes from analysis [as above] and not from opinion. As I have said many times, I would love that there was some real correlations as that would vastly improved my funding situation, but, alas, is doesn’t seem there is. The notion of ‘open mind’ is silly.One should go as far as the data takes you, but not much further.

November 12, 2011 2:17 am

Now let’s make this absolutely clear:
Business of the 60 year cycle in the magnetosphere was raised by myself in an exchange involving Dr. Scafetta and Dr. Loehle on the Judith Curry’s blog:
http://judithcurry.com/2011/07/25/loehle-and-scafetta-on-climate-change-attribution/#comment-90560
Although it was meant as a half-hearted comment, which is obvious from the tone of my post, but to my surprise, it was then taken seriously by both Dr. Scafetta and Dr. Loehle.
I have looked into this, analysing number indicators considered as acceptable and widely available data sunspot record, Ap index, the Arctic’s magnetic field differential and McCracken data for the strength of magnetosphere at the Earth’s orbit, no evidence was found for consistent 60 year cycle.
I did not look into auroras, but if I had data I would not taken it as reliable enough, since the other four relevant and by the science accepted data-sets have drawn a blank.
McCracken data (he is retired NASA scientist) should be the first and a must reference to anyone investigating magnetosphere, but there is no mention of it in Scafetta’s work.
Neither Dr. Leohle or Dr. Scafetta have prior to the above exchange on Climate etc. blog shown any interest in magnetosphere’s effects as far as I know, but Dr. Scafetta should be able to give precise details if he did, since Dr. Loehle has withdrawn from the equation in this new paper.
My ‘credentials’ in this area as ‘good or lousy’ are well known to the WUWT readers, but I do invite those interested to visit the above link and familiarise themselves with the exchange.
I also invite Dr. Scafetta to comment.

November 12, 2011 5:20 am

Sorry Leif,
You are just making confusion by randomly using proposed proxy data in an inappropriate way.
The proxy models must be used with intelligence. The aurora record I use is not a proxy model but direct observation of what was happening in the upper atmosphere. So, it is far above any of your proxy models.
For example, when using a proxy model for cosmic ray or other, you need first to understand that it is a proxy model and not a direct measurement, then you need to understand that those kind of proxy model might have huge uncertenties, then you need to understand that a given proxy model may refer not to any kind of cosmic rays but to specific cosmic ray energy bands, then you need to understand that it is not yet known which kind of cosmic rays may be influencing the cloud system most, then you need to understand that cosmic rays alone may not be sufficient because there might be other effect directly related to the electric properties of the athmosphere that may be regulated by something more than just cosmic ray, etc.
Then you need to look at the data that I explicitly report in the paper istead of just randomly look at what you like.
Then you need to read the references used in the paper.
For example
Earth(Klyashtorin,2001; KlyashtorinandLyubushin,2007;
Klyashtorinetal.,2009; Le Mou¨el et al.,2008; Camuffoetal.,

see figure 11 and 12 with their huge peak at around 60 year.
Another paper is

DIRECT SOLAR DATA AND PROXIES
OGURTSOV et al.
http://www.springerlink.com/content/q1740143246t005l/fulltext.pdf
several figures show spectral peaks around 60 year
Many other papers do the same.
Thus, as Lucy Skywalker says ( November 11, 2011 at 5:05)
Your confused way of reasoning is just “Rubbish. Scafetta has already showed six different indices in his paper which all show with stunning clarity the formative presence of a 60-year cycle: PDO, AMO, auroras, monsoons, meteorites, and global temperatures (detrended etc). Thus replication has already succeeded so the claim holds so far. The correlations are highly evocative, I don’t know how to quantify them statistically but visually they shout. Thus the likelihood increases that your apparent non-correlations may have other factors at work, that do not disprove the presence of a 60-year cycle.”
So, please, stop reasoning in a rubbish way and open your mind.
If you start showing a little bit of respect and try a small apology it would not be a bad idea also.

Figure 11 is important because it shows for the first time that climate can be forecast based on astronomical harmonics with a good accuracy.
I use a methodology similar to Kelvin’s one and calibrate the model from 1850 to 1950 and I show that the model predicts the climate oscillations from 1950 to 2010, and I show also that the vice-versa is possible.

mit dem Ausbleiben der Sonnenflecken, wie im 17. Jahrhundert
zusammenfaellt, sondern auch, weil es ein einfacher astrologischer
Index ist, fuer die Zukunft die Sonnen Aktivitaet bestimmen kann. Fuer
die naechsten Jahrzehnte wuerde sich danach die Sonnen Aktivitaet weiter
verringern, was dann mit einer Abnahme der mittleren Temperatur
einhergehen wuerde. Ich bin gerade dabei den Geometrischen Harmonie Index auch fuerr die
zurueck liegenden Zeiten bis ~2000 B.C. zu berechnen.

The index I have called Geometric Harmonic Index (GHI) in February 2010 is based und two discoveries I did in that month. The first discovery was that I have found that the synodic frequency of the plutinos Quaoar and Pluto was 1827.07 years^-1 [ 1/f = 1/(1/248.09-1/287.07) = 1827.07 years^-1 ], which correlates with the half main frequency J.R. Eddy and Dansgaard have found in samples. The second discovery was that the temperature phases of the data from both J.R Eddy and Dansgaard where coherent in time with the solar tide function of the plutino couple in that way that Nip tides correspond to cold times like the LIA, and Spring tides correspond with warm times:
http://volker-doormann.org/images/ghi_6000.gif
Adding solar tide functions from nine more planets (Mercury to Neptune) to that basic GHI it is obvious as has been show here already in this thread that such high frequency temperature data like Hadcrut3 correlates also with the refined GHI 11.
http://volker-doormann.org/images/ghi_11_had1960.gif
http://volker-doormann.org/images/ghi_11_hadcrut3.gif
I think it is not correct to claim “I can forecast climate with a good proximity … it shows for the first time that climate can be forecast based on astronomical harmonics with a good accuracy.” with a ~60 year cycle (without any relation to real frequencies in the solar system) without any nature.
The above image shows the nature of the tide function of Quaoar and Pluto, and it results from the eccentricity of Pluto that over the time each exact Nip tide angle and both spring tide angles are mostly occurs three times in two centuries. Because of this it is senseless to think in cycles; cycles do say nothing. Moreover, it is well known that FFT analyses from temperature spectra searching only for sinusoid frequencies, and this leads astray, fitting simulations of ‘cycles’ to the temperature proxies. The only successful method is to take the NASA ephemeris of the objects in the solar system which are available -5000 years +1000 years.
There is a difference whether a true conclusion comes from fallacious arguments or valid arguments. That a decreasing temperature is forecast from a fallacious arguments can be happen, but it is always a fallacy:
“Take the fraction 16/64. Now, canceling a six on top and a six on the bottom, we get that 16/64 = 1/4.”
“Wait a second! You can’t just cancel the six!”
“Oh, so you’re telling us 16/64 is not equal to 1/4, are you?”

The proxy models must be used with intelligence. The aurora record I use is not a proxy model but direct observation of what was happening in the upper atmosphere. So, it is far above any of your proxy models.
The magnetic effect of the currents that flow in the aurora is not a proxy model or effect, but a direct measure of said currents [which can be verified by rockets and spacecraft]. It is as direct as measurements of electric current with an ammeter [ http://en.wikipedia.org/wiki/Ammeter ], or would you say that such measurements are just proxy models?
For example, when using a proxy model for cosmic ray or other, you need first to understand that it is a proxy model and not a direct measurement, then you need to understand that those kind of proxy model might have huge uncertainties
The 10Be data are good enough to show the solar cycle.
Then you need to look at the data that I explicitly report in the paper instead of just randomly look at what you like.
First of all, I don’t look randomly at anything, I go directly to the relevant data [the directly measured magnetic effects of the currents flowing in the aurora]. Second, by looking at those very reliable data rather than difficult to calibrate auroral sightings one is much closer to reality.
If you start showing a little bit of respect and try a small apology it would not be a bad idea also.
It shows respect to even considering your paper, without using words like ‘confused’, ‘rubbish’, etc.

Incorrect focus on global average cloud.
Temperature gradients drive the equator-pole pressure gradient force. Where gradients are steep at mid-latitudes, flow is deflected 90 degrees (to the right = westerly) by Coriolis. However, there are exceptions due to factors such as surface friction and notably east coasts. (See links below to animations of land-ocean temperature-gradient geometry & resultant wind.)
Temperature gradient spatial pattern & east coast circulation deflection varies multidecadally as a function of solar cycle acceleration.
The focus should be on solar & lunisolar input vector effects on absolute temperature gradient patterns.
The solar input vector may have small variance but its effect is NOT spatially uniform across day & night, across summer & winter, across land & ocean, etc. because the input response field is heterogeneous & nonstationary. It’s the gradients in the field that drive flow (including flow direction). Changes in the solar input vector drive changes in circulatory pattern. See p.4 here: http://wattsupwiththat.files.wordpress.com/2011/10/vaughn-sun-earth-moon-harmonies-beats-biases.pdf
The sun strums our lunisolar framework. It’s real simple.
A small change in flow angle has MAJOR consequences for climate. This has been known since at least the 1940s. What wasn’t known publicly before 2010 was that the spatial patterns and their deflections are a function of solar cycle acceleration. The westerlies circle the Earth faster than it rotates. When they straighten out or go loopy, that’s a change in how the radiator’s operating. (The window may still be open the same or a similar amount, but the fan is turned on or off or to a different speed.)
It’s not just the latitude of sharpest temperature gradient, but also the SHAPE. During times of stronger land-ocean contrast, “loopiness” is higher meaning the flow travels a longer path length and that boundaries fill more space. A mathematician would say the fractal dimension is higher, meaning length:area & area:volume ratios are higher.
Speculation: I suspect that if we look more carefully we’ll see that solar input vector changes also act through the spatial input response filter as a westerly/easterly mid-latitude/equatorial warm pool control valve at interannual timescales and that this will explain most EOP variation with possibly as few as 3 key terrestrial asymmetries.
I suggest people make an effort to visualize the fractal dimension asymmetries (contrasting north-south “loopiness” vs. “straightness”) by starting with the average annual cycle.

Note that the southeast coast of South America is perpendicular (minimizing length of intersection of coastline / steep gradient with flow path) to what it would need to be to have an effect closer in strength to what we see for longer GS, KOE, & IPWP temperature gradients (i.e. to better match the sideways westerly-easterly-westerly V).

Dr. Scafetta: Gradients cannot be ignored. We can’t just look at averages. Regardless of the external inputs, Earth has strong gradient patterns. Anyone studying external factors affecting Earth must get to know Earth’s shifting spatial filter. Please don’t try to model averages. Please try to model the shape of gradients. This is the ONLY way.
A basic first-order test of whether the climate symmetries are balanced correctly in models (and thus whether models warrant any consideration whatsoever): They should reproduce EOP (Earth Orientation Parameters).
Thanks for producing articles to stimulate discussion. (Meanwhile we see that others only want to shut down nature appreciation & efforts to understand nature. Not even remotely acceptable.)
Here’s an experiment for readers to try:
Flip a fan between speeds such that aliasing causes the apparent blade rotation direct to reverse. Do this flipping quasi-stationarily in time, but sample apparent rotation direction stationarily at a higher (but not too high) frequency. Plot the results. [ http://wattsupwiththat.files.wordpress.com/2011/10/vaughn4.png ]
EOP can be used to quantify the anthropogenic effect on climate, but when NASA tried this they used the wrong metric [ http://www.nasa.gov/topics/earth/features/earth20110309.html ].
The problem: Fundamentally misguided anomaly-think where gradient summaries are the appropriate metrics. (Same conceptual framework problem the climatologists are having. Same problem the solar physicists are having with differential solar rotation data exploration.)
Conventional mainstream conceptualization of how to detect changing drive wheel speed through differential transmission networks appears fundamentally flawed. Central mainstreamers appear to not realize that pulse position modulation is differential when there is no locked-clock. (For example, it should be simple enough to see that when calculating the rate of change of delta LOD, the constant cancels out, but mainstreamers are irrationally attached to the notion that the constant remains meaningful for purposes beyond eminently-sensible first-order approximation, which isn’t enough for multidecadal exploration, particularly given changes in the location & state of water).

Then you need to look at the data that I explicitly report in the paper
Have done that many times. You auroral data seems to come from ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/AURORAE/aurorae.dat.rev [Krisky and Pejml, 1988] and has data back to year 1000, which you ignore. The record 1000-1700 does not show any 60-year period, although the 11-year period is present. Krivsky discusses the ‘civilization’ factor, namely how the number of reported aurora depends on cultural, technologically, and possibly even climate factors. A good example of how unreliable the auroral record is, is your Faroe record which shows a high frequency in the beginning of the 20th century when solar activity was very low and a low frequency in the 1940s when solar activity was very high. So, the auroral data is not a stable and reliable proxy for the electric currents in the ionosphere. The magnetic data I provided is the best, objective, civilization-, and observer-independent data we have. The sunspot number [although less reliable] also shows no 60-year cycle.

November 12, 2011 11:49 am

Dr. S.
Correct, it was a slip, meant strength of heliosphere at the Earth’s orbit.
Either way from historic perspective, McCracken paper is advisable, but I think he is a bit mean with periodicities only mentions 22 and 2300, but my spectrum analyser shows minor peaks at 43 and 61 years and most significantly at 107 years, confirming what is shown here as relevant:
http://www.vukcevic.talktalk.net/CETs.htm
107 = (118+96)/2 and 11 = (118 – 96)/2 as cross modulation frequency products, suggesting the poor old sol has no periodicity of its own!
Nearly forgot McCracken spectrum:
http://www.vukcevic.talktalk.net/McC.htm
May be the Earth’s magnetosphere gets zapped a bit stronger every 60 years as per Vukcevic:
I suggest have a careful look at this NASA’s link:

Observe that a large fraction of the solar system, in its equatorial plane, gets engulfed with the CME.
http://ase.tufts.edu/cosmos/pictures/Sept09/Fig8_7.MagCloud.gif
Underlining effects are close circuits (closing at the solar surface) of magnetic field and electric currents. Both magnetic field and electric current are partially short-circuited by the huge magnetospheres of both Jupiter and Saturn (known as magnetic reconnection).
Every 19.859 years this short-circuiting is particularly effective since both planets find themselves in the same direction. Now imagine our little Earth zipping in between, its tiny magnetic field gets zapped by these huge currents:
http://www.vukcevic.talktalk.net/HmL.htm
Heliosphere is highly squashed in the head on direction so the effectiveness of the zap is far more severe when both Jupiter and Saturn find themselves in this head on direction. This happens every 59.5 years

Note for Dr. Scafetta:
You are welcome to use any of the above, if that is of any interest to you, but it would be courteous to remember where it came from.

Now imagine our little Earth zipping in between, its tiny magnetic field gets zapped by these huge currents
There are no huge currents and no ‘shorts’. The solar wind is supersonic and sweeps everything outwards. The only exception is the very rare particles with very high energy [both in the solar wind and in cosmic rays and at times generated locally] that can travel much more freely. So there can be counter-streaming electrons and other such phenomena, but those are not huge currents and have no measurable effects on anything. When a CME hits Jupiter and Earth is in one of the ‘legs’ still connecting Sun and the CME we don’t see a thing. [nobody has reported any effect].

“When they (the jets) straighten out or go loopy, that’s a change in how the radiator’s operating”
Correct.
“Incorrect focus on global average cloud.”
Wrong.
Long loopy jets give a higher global cloudiness than straightened out jets.The length of the areas of mixing between differing air masses increases and it is that mixing that produces clouds.
In equatorial regions where it matters most the widening equatorial climate zones during a warming spell reduce cloudiness further by dissipating low cloud cover over parts of the equatorial oceans. The size of the high pressure cells with their descending air either side of the ITCZ are critical in that respect.
However the trick for the Earth system is that despite the increased sunshine into the oceans that energy is shoved out to space just as fast due to the faster water cycle from the poleward shift of the climate zones. Subject, that is, to modulations by ocean cycles which do vary the rate at which solar input is returned to the air.
It really is that simple 🙂

Since there are no huge currents nobody has a motivation to even look. CMEs push into to solar wind on the way out, but never the other way. We measure by spacecraft also the flow direction of the interplanetary material and it is always out.

Except he does not believe the cosmic ray record is any good 🙂
Now, we have two different records [14C and 10Be]. Plotting them together: http://www.leif.org/research/14C-10Be-Comparison.png shows some fair agreement [but also some of the problems]. For 1700-1900 there is a weak 60-yr period [in the red box] and Scafetta picked that up, but the point is that the relation fails outside of the red box while the planets just cycle on with no failures. So, the claim of planetary cycles determining cosmic ray flux [or solar activity or aurorae etc] is spurious because once we go outside the box on which the correlation is based, it fails. If the planetary theory is to be taken seriously [as a major driver] it must work at all times. If the theory is only a weak modulation with almost no effect, one can allow intermittent failures.

November 12, 2011 2:13 pm

I never thought that his ‘aurora business’ is as reliable as the other relevant and testable data. Since the only way to explain 60 year periodicity is ‘vukcevic hypothesis’ of the Earth being ‘zapped’ more often at a particular heliocentric direction (head or tail), Scafetta has a choice either to pursue the current strategy, or to switch from the auroras to the McCracken’s.
Instead a vague assumptions about the E/J/S magnetospheres within the heliosphere, with a bit of gravitation thrown in, he has a clear cut case with the ‘vukcevic hypothesis’ which can be eventually proven by observations of J/S magnetospheres.
According to JPL ‘The aurora is dynamic on Jupiter, just as it is here on Earth’ and the Saturn auroras appear to be spectacular.
Earth gets zapped 2-3 days after the ejection, Jupiter perhaps 20-30 days later and for Saturn double that; perhaps the reason why they are not correlated before. In any case the Saturn auroras have been observed only in the recent years (notably by Cassini probe).
Hay, even staying in all day and fighting nasty ‘cold or flu’, it ain’t that bad after all, if there is something to do
Time to sign off.

November 12, 2011 3:04 pm

Leif is incorrigible! Leif did not undestand anything!
“A good example of how unreliable the auroral record is, is your Faroe record which shows a high frequency in the beginning of the 20th century when solar activity was very low and a low frequency in the 1940s when solar activity was very high. ”
The number of midlatitude auroras is a function of the planetary configuration that regulate the heliosphee and inversely proportional to the multidecadal decadal activity of solar activity. Everthing is clearly explained in the paper. Mid-latitude aurora are more easily seen during the cold multidecadal periods!
“Regardless, Scafetta’s P1(t) functrion does not match McC’s cosmic ray record”
Leif took a modulation function I created for simulating the modulation of the “temperature” between the time scale of 10 to 60 year which ignores both the fast frequencies and the secular time scales and also includes a lunar cycle that has nothing to do with cosmic ray, and Leif claims that I am wrong because that temperature modulation limited to the multidecadal pattern does not correspond exactly to a McC’s cosmic ray record. However, my multidecadal temperature modulation was NEVER supposed to represent a specific cosmic ray multisecular record deduced from a specific ground proxy!
Other garbage, Leif ? Open your mind, it needs fresh air, Leif !
My paper focuses on a shared frequency set between the aurora records and the temperature and the astronomical oscillations of the solar system. That is the topic of the paper, Leif! please, focus on the topic.
Comments of some of the above readers about Leif’s sophistic way of reasoning:
Ged said (November 11, 2011 at 10:14 am): “But just saying there’s no power spectrum showing 60 seems ignorant, since the paper shows that in several ways, clearly.”
Lucy Skywalker said ( November 11, 2011 at 5:05)
“Rubbish. Scafetta has already showed six different indices in his paper which all show with stunning clarity the formative presence of a 60-year cycle: PDO, AMO, auroras, monsoons, meteorites, and global temperatures (detrended etc). Thus replication has already succeeded so the claim holds so far. The correlations are highly evocative, I don’t know how to quantify them statistically but visually they shout. Thus the likelihood increases that your apparent non-correlations may have other factors at work, that do not disprove the presence of a 60-year cycle.”
Sorry, Leif ! But the above is the truth.

“This is completely irrelevant for solar activity and generation of aurorae which takes place tens of thousands of miles above the Earth..”
=======
With great trepidation I offer the following, from:
http://odin.gi.alaska.edu/FAQ/#altitude
3) What is the altitude of aurora?
The bottom edge is typically at 100km (60 miles) altitude.
The aurora extends over a very large altitude range. The altitude where the emission comes from depends on the energy of the energetic electrons that make the aurora. The more energy the bigger the punch, and the deeper the electron gets into the atmosphere. Very intense aurora from high energy electrons can be as low as 80 km (50 miles). The top of the visible aurora peters out at about 2-300 km (120-200 miles), but sometimes high altitude aurora can be seen as high as 600 km (350 miles). This is about the altitude at which the space shuttle usually flies.

I assume Leif’s comment is more about the generation altitude than the visible altitude ?

The number of midlatitude auroras is a function of the planetary configuration that regulate the heliosphere and inversely proportional to the multidecadal decadal activity of solar activity.
No, it is a function of the magnetic field at Earth times the square of the solar wind speed times the cube root of the solar wind density times a steep function of the angle between the magnetic field in the solar wind and the Earth’s magnetic field. In particular, it is not inversely proportional to solar activity.
However, my multidecadal temperature modulation was NEVER supposed to represent a specific cosmic ray multisecular record deduced from a specific ground proxy!
So, was NEVER supposed to represent solar activity and auroral frequency. I’ll take note of that admission and stop believing you were talking about solar activity, cosmic rays, and aurorae.

To all readers,
I am sorry but Leif in my opinion is only trying to mislead the readers of this blog.
In my opinion he always twists things, suppresses logic, alters the contents of my paper, switches arguments, mixes data, confounds models and at the end he remains the only one convinced of his own imaginary world.
It is evident that a constructive discussion with Leif is not possible, not for my fault but for his prejudiced hostility agaist every paper and every concept that I write, what ever it might be.
And unfortunately this is a story that is continuing since several years.
Those of you that might be interested in my research, please read my papers. Do not relay only on what Leif says.
Reading carefully my paper is the only way to understand my reasoning and what I have found. Often you may also need to read the refrences if you want to get the big picture.
If you read my papers, please take into account that this paper as well as the other ones are not the end of the story and never it was supposed to be the end of the story. It is very important to understand that science progress one step by time, my paper is not supposed to solve any possible issue in the universe one might think.
This is true for my paper as well as for any other scientific paper.
As a reader said above, science is full of misteries.
So, please consider than science is hard because those who try to do that try to understand nature.
I thank Anthony for this opportunity to discuss my paper here. But I am quite busy so I need now to end my contributions.
Hopefully, in the future we can continue the discussion addressing some other aspect of the big picture.
Thank you very much to all, including Leif, of course.

Nicola Scaffeta;
Though plenty of the discuission was over my head, I for one appreciate your work and look forward to seeing more of it. I find some of the criticisms frankly, obtuse. You’ve demonstrated the ability to both forecast and hindcast from what would appear to be unrelated data with remarkable precision. My expectation is that with more accurate data and additional factors beyond those you have already incorporated, the precision will improve still more. Leif and others may dispute the mechanisms involved, and they may even be right in some cases, but results that are accurate speak for themselves regardless of why it is that they are accurate.

The bottom edge is typically at 100km (60 miles) altitude. […]
I assume Leif’s comment is more about the generation altitude than the visible altitude ?
Yes. the aurora stems from processes far out in the magnetosphere where magnetic reconnection creates electric fields that accelerate particles along field lines to eventually plunge into the upper atmosphere where they excite Nitrogen and Oxygen to glow.

It is evident that a constructive discussion with Leif is not possible, not for my fault but for his prejudiced hostility agaist every paper and every concept that I write, what ever it might be.
I criticize every paper, post, or comment that I find flawed. Several posters here can testify to that having been on the receiving end. What makes you think you are any better than those good folks?
All my criticism is, of course, my personal opinion based only on what I know and on analysis I may make of a paper. I’m probably the one person that have analysed your paper and data better than anybody else [including the referees, it would seem]. That should make you glad and proud.
No doubt you’ll find solace in the postings from various people that have expressed gratitude for and delight in your research. Such is life, you win or lose adherents and sycophants one at a time.

“About CET you clealy see maxima around 1940 and 2000. Then the 60-year cycle predicts a maximum in 1880s which is seen in the global temperature data. However CET does see a cooling instead of a warming. This is probably because in the 1880s there was a huge Krakatoa volcano eruption that might have caused a significant cooling in England and disrupted the pattern. Then the 60 year cycle predicts a maximum around 1820 and a minimum around 1790 and these are there. Before 1790 CET is very poor, and the patterns are less clear. So a 60-year cycle may be present in CET although it may be disrupted by some volcano activity in particular in the 1880s.”
Krakatau was in 1883, but 1884 was very warm on CET: http://climexp.knmi.nl/data/tcet.dat
The worst cold anomalies around then were in 1879-81 and 1885-88. To be really convincing, planetary theory needs to explain these deviations from normals at the scale they are occurring in the weather.

The focus on cloud is overly-narrow because too many (perhaps even most) contributors fixate on it without (sufficient) awareness of temperature gradient geometry, mass distribution, equator-pole pressure gradient force, & circulation. (Also, there’s that pesky problem that the data don’t support the over-simplified cloud narrative.)

The Day the Solar Wind Disappeared

is what the McCracken data spectrum shows, the GCR’s periodic ‘wobble’.
http://www.vukcevic.talktalk.net/McC.htm
but what is more important it proves that the Sunspot anomaly formula, I published in 2004
http://cdsweb.cern.ch/record/704882/files/0401107.pdf (page2) and shown here in more detail
http://www.vukcevic.talktalk.net/LFC4.htm
is firmly embedded in the 10Be data records.
This is result of another cross modulation process within solar activity, which may come to the solar scientists as a bit of a shock, but it is the bread and butter of every day’s existence for a designer of old fashioned analogue electronic circuits.
No mysteries in science then.
You may have enjoyed ‘rubbishing’ my equations for the last 3-4 years, but all three equations published in 2004, not a result of any expertise in solar physics, but just simply recognising cross-modulation patterns are far more than jumble of cosine functions.
http://www.vukcevic.talktalk.net/NFC7a.htm
But of course as I’ve reported elsewhere McCracken misinterpreted the 10Be data, which when fully explained it will give science another problem to resolve, the North Atlantic Precursor, the true link between the solar activity and climate variability:
http://www.vukcevic.talktalk.net/CET-NV.htm
Notice casual similarity between the natural climate variability (blue line) and the N.A. precursor (red line) against the background of the solar cycles progression, closer to now, closer the correspondence. The r^2 is good!

November 12, 2011 10:53 pm

Sorry Leif, but you are clearly not an expert in this field and your improper comments prove it extensively.
Moreover, your way of reasoning contradicts basic concepts of philosophy and are filled with numerous logical fallacies such as the claim that the physical information contained in one record must be wrong for the simple motivation that the physical information contained in another record, not related to the first one, may be different.
One of the numerous fallacies that you systematically adopt is the “Straw Man” logical fallacy. But there are many more logical fallacies in your reasoning such as false analogy, red herring, ignoratio elenchi, ad hominem (your new insinuations toward the referees of my paper that you do not know) , etc.
From http://en.wikipedia.org/wiki/Straw_man
Straw man is a component of an argument and is an informal fallacy based on misrepresentation of an opponent’s position, twisting his words or by means of [false] assumptions To “attack a straw man” is to create the illusion of having refuted a proposition by replacing it with a superficially similar yet unequivalent proposition (the “straw man”), and refuting it, without ever having actually refuted the original position. Generally, the straw man is a highly exaggerated[citation needed] or over-simplified version of the opponent’s original statement, which has been distorted to the point of absurdity. This exaggerated or distorted statement is thus easily argued against, but is a misrepresentation of the opponent’s actual statement.
The straw man fallacy occurs in the following pattern of argument:
1.Person A has position X.
2.Person B disregards certain key points of X and instead presents the superficially similar position Y. Thus, Y is a resulting distorted version of X and can be set up in several ways, including: 1.Presenting a misrepresentation of the opponent’s position.
2.Quoting an opponent’s words out of context — i.e. choosing quotations that misrepresent the opponent’s actual intentions (see fallacy of quoting out of context).[2]
3.Presenting someone who defends a position poorly as the defender, then refuting that person’s arguments — thus giving the appearance that every upholder of that position (and thus the position itself) has been defeated.[1]
4.Inventing a fictitious persona with actions or beliefs which are then criticized, implying that the person represents a group of whom the speaker is critical.
5.Oversimplifying an opponent’s argument, then attacking this oversimplified version.
3.Person B attacks position Y, concluding that X is false/incorrect/flawed.
This sort of “reasoning” is fallacious, because attacking a distorted version of a position fails to constitute an attack on the actual position.
In fact, dear Leif, you have not proven that the issue addressed in my paper (that is, the mid-latitude aurora historical records present the same major frequencies of the global surface temperature and of major astronomical oscillations of the heliosphere associated to the movements of Jupiter and Saturn plus some additiona Soli/Lunar frequency) is wrong.
You just skattered around proposing and disproving your own understanding of the world.
@Ulric Lyons
Dear Ulric, in my paper I am not addressing the CET record which is a very local temperature record. What matters is not what happened in central England in the 1880s but what happened in the entire world in 1880s. In the 1880s in central England was apparently anomalously cold for most years, but in the entire world was relatively warm during that same period as predicted by the 60-year cycle: see figure 2A in my paper. Moreover, the model proposed in the paper is not supposed to predict the temperature in specific locations such as central England, central Bulgaria, central Sudan, or central Virginia or central NoWhere, but it gives an estimate of the global patterns. Local patterns do not move exactly like the global average. The world may warm but a specific location may cool, that is normal. Finally the proposed model is not supposed to explain year by year the temperature locally or globally because it has a decadal to 60-year scale resolution and does not contain at this point shorter or longer time scale resolutions.

That would lead one to assume considerable ignorance on your part.
To understand climate you need to understand the CET, which is not just Central England, it is the North Atlantic basin, the home of the AMO, the most influential variable on the so called ‘global temperatures’ as the BEST team tells us that it is so.
The CET is the only long reliable temperature record we have, and as any physicist will tell you ‘global temperature’ is bit of nonsense but that doesn’t stop statisticians having lot of fun adding and subtracting lots of spurious and questionable records, to formulate their hypothesis, which rise from equally spurious computer models.
Learn the CET’s past and you will acquire precious knowledge of the climate system.

Astrology has never been my strong side, only auroral and geomagnetic physics with some solar physics and orbital mechanics thrown in. But since you don’t address any of those in a satisfactory manner it seems that you are too far out on the fringe for meaningful discussion, so being sorry is perhaps a good attitude to have. Just be glad that I have taken time to look at your paper(s).
In fact, dear Leif, you have not proven that the issue addressed in my paper (that is, the mid-latitude aurora historical records present the same major frequencies of the global surface temperature and of major astronomical oscillations of the heliosphere associated to the movements of Jupiter and Saturn plus some additiona Soli/Lunar frequency) is wrong.
You have this a bit backwards, you have not shown that your ideas are right or even plausible. Put is differently, I may have a higher bar for what is good science than you have, but there is a continuum all the way from that down to outright quackery. Too bad that some [but not all] journals are sliding downwards on that slope.

Some comments: the 14C is from Raymod Mueschler [personal communication] and the 10Be is from Ken McCracken [personal communication] (corrected for glitch around 1950 – Figure 2 of http://www.leif.org/research/Svalgaard_ISSI_Proposal_Base ). The units are converted to HMF B nT, but the scales are really arbitrary. The only things of value are the relative variations. There are differences, but also substantial agreements. What you are looking at is in a sense ‘the state of the art’. We hope in Bern next year to have ironed out the differences and to converge on something we all can agree to (or at least put error bars on).

You can learn more about the relationship between aurorae and geomagnetic activity here:
http://www.swpc.noaa.gov/Aurora/index.html [see also http://www.swpc.noaa.gov/pmap/ for current conditions]. From the link: “Being able to see the Aurora depends mainly on two factors, geomagnetic activity (the degree of disturbance of the earth’s magnetic field at the time) and your geographic location”. To see aurora below 55N you need a K-index of at least 7. The geomagnetic indices tell you when that happens so are a very correct and sensitive and objective measure of auroral activity [better than auroral sightings that are unreliable and uncalibrated]. And geomagnetic activity [when we have good and unambiguous records] since the 1840s shows no 60-year cycle. In my book that is enough to show me that your claim is spurious.

Leif is incorrigible! Leif did not understand anything! The number of midlatitude auroras is a function of the planetary configuration that regulate the heliosphere and inversely proportional to the multidecadal decadal activity of solar activity.

No, it is a function of the magnetic field at Earth times the square of the solar wind speed times the cube root of the solar wind density times a steep function of the angle between the magnetic field in the solar wind and the Earth’s magnetic field. In particular, it is not inversely proportional to solar activity.
Is it possible that BOTH of you carry elements of verifiable hypothesis here? ie there is a factor of “inverse proportionality to solar activity” but also the functions Leif mentions? It seems to me perfectly plausible that while the 60-year cycle shines through, there are also other factors at work – and that Leif may, just may, have a handle on those.
From the POV of climate science, the question is, what factor or combination of factors best corresponds to climate data? Volker Doorman’s work also looks interesting (though not conclusive) in this respect. And Richard Holle’s. And of course the Russian scientists don’t have the same coyness (or ignorance and rudeness) about planetary influences correlations that we inherit in the “West”.

The global mean was falling through the 1880`s:
http://www.woodfortrees.org/plot/hadcrut3gl/from:1850/to:1930
The peaks at 1878/9, 1885/6 and 1888/9 are El Nino events, the first and last being strong events.
To properly appreciate the detail in the global average, one has to aware that El Nino events are brought on by falling and lower solar wind speeds (less aurora if you prefer that measure), and so can tend to run contrary to negative monthly/seasonal land temperature deviations occurring during lower SW speeds.
The colder months on CET are all there across Europe too:
http://members.multimania.nl/ErrenWijlens/co2/centraleuropetempupd.gif
and mostly agree with US temperature series (see graphs):
http://www.climatestations.com/chicago/
so are not a local phenomena, but a response to short term solar variations.

No, there is no factor of ‘inverse proportionality’. The number of aurorae is directly proportional to solar activity as has been known for more than 150 years. “Auroral displays are more likely around the time of the solar activity maximum (2000-2001 in the current cycle).” http://www.pfrr.alaska.edu/aurora/index.html

REPLY: I’ll second that. Give a procedure. – Anthony

November 13, 2011 11:38 am

Dear Leif,
if everybody analize and understand physical data as you do, science will never progress.
About the aurora records, first I am studying the historical mid-latitude aurora (<55N), not any kind of aurora such as those in Alaska at (60N-70N) and at high latitude monitoring stations that you reference in your link.
Second. the mid-latitude aurora records present a decadal oscillations approximately correlated to the 11-year solar cycle as you expect that would happen. However, the 60 year cycle that the middle latitude aurora records present is clearly negative-correlated to solar activity, as Figure 2 shows. So, as you have brillantly noted, we have a lot a mid-latitude auroras during the 1900-1910 when the multidecadal solar activity was at a minimum. All these things are clearly explained in my paper and justify the qualitative mechanism I propose in section 2 and 7.
So, mid-latitude formations clearly have multiple physical causes, not just the one that you understand.
So, please do not continue in your logical fallacy arguments by mixing and confounding things around. This time yours is also an ignoratio elenchi logical fallacy. You start assuming that a phenomenon has only one single cause (the one that you know), then you mistake one record (polar auroras in Alaska 60-70N and equivalent latitudes) for another (mid-latitude aurora at <55N that I use) and you assume that all auora records at all latitudes must behave in the same identical way.
Then you claim that because the data that I use do not show what you expect and, you deny the data and my analysis instead of questioning your initial reductionistic assumption and mistaken reference record that refers to a phenomenon different from that I analyzed (=the Straw Man logical fallacy argument).
Sorry, Leif ! This is not how people understand Nature, Leif !
@ Vukcevic and Ulric Lyons about CET.
As I have explained above, in the paper I am addressing the global surface temperature and the things correlate well. Then I study some proxy models all over the world (AMO, PDO, Monsoon: see figure 3) and I show that an agreement with my theory is found. The same refers to several other data discussed in my citations.
On the contrary the CET refers only to the Cental England region. It is sensitive to local weather oscillations and local events (also thermometers that break or are re-located) and may be strongly effected by vocano effecs. I have explained above that CET too seems to me to be approximately compatible with my theory if you take into account the volcano activity that disrupt the patterns, for example. However, because CET is not the topic of the paper, the paper does not address this specific issue. Is it so difficult for you to understand this elementary point fact?
When I will publish a paper with the title "Analysis and implications of the Central England Temperature record" we can discuss your points.
Anothe paper of mine addresses the NAO index which include the CET plus several other hystorical measurement indexes taken all over Europe. This is:
A. Mazzarella and N. Scafetta, "Evidences for a quasi 60-year North Atlantic Oscillation since 1700 and its meaning for global climate change," Theor. Appl. Climatol., DOI 10.1007/s00704-011-0499-4 (2011).
And the things correlate well with my hypotheses.
So, what you need to do is first not to imitate Leif, second try to study my paper and its references that discusses several of these issues with calm and interest, if you like.

No, we know quite well here the mid-latitude aurorae come from. There is no other physical cause than the one I described. That the 1900-1910 record shows otherwise just shows how unreliable auroral records are [apart from the fact that the Faroe islands are at 62 degrees N and pretty close to the auroral zone and thus are not at ‘mid-latitudes’].

November 13, 2011 12:24 pm

Sorry Leif, you are clearly denying the data. The data is what suggests the mechanisms in physics, not viceversa.
You must prove that the data that I am using are wrong, not claiming that my results are wrong just because you BELIEVE that the data are wrong because they do not fit your imagination!
Another logical fallacy, Leif? In this case it is called Mind-Projection-Fallacy
http://en.wikipedia.org/wiki/Mind_Projection_Fallacy
Mind projection fallacy, as coined by physicist and bayesian philosopher E.T. Jaynes, occurs when one takes for sure that the way he sees the world reflects the way the world really is despite the contrary evidences.
As I have explained in the paper the Faroe aurora data were included because despite they are located at 62N people expert in aurora records have noted a strong similarity of these auroras with the mid-latitude auroras at <55N (a unique case). So I have analyzed also the Faroe records too and I found the same results found in the Mid-latitude auroras A coincidence, dear Leif?
So, dear Leif, what is your demonstration that both auroras records I analyzed are wrong?

… ie there is a factor of “inverse proportionality to solar activity” but also the functions Leif mentions? It seems to me perfectly plausible that while the 60-year cycle shines through, there are also other factors at work
Hi Lucy Skywalker,
there is a correlation between the inverse Neutron rate (Climax) and the global temperature (Hadcrut3 and UAH).
http://volker-doormann.org/images/ghi_11_jux5.gif
From the POV of climate science, the question is, what factor or combination of factors best corresponds to climate data? Volker Doorman’s work also looks interesting (though not conclusive) in this respect.
It seems that hot spots in the range of a year or so are not connected to the GHI background of solar tide functions of synodic couples. This is especially visible in the late fifties and between 2000 and 2010. But several spikes (lack of Neutrons) in the climax spectrum are also visible in the temperature proxies.
There is a clear evidence that the frequency of the sun spot pattern is shifted in both directions from its main frequency of 1/11.196 year^-1 , and this is correlated with increasing temperatures (+f) or decreasing temperatures (-f) like in this year. Maybe it is also a long term tide effect which acts on the surface of the sun; I don’t know.
http://volker-doormann.org/images/sp_shift_vs_proxies.gif
If the Sun has a stable oscillator of f = 1/11.196 years^-1 but surface processes from tides do shift the visible frequency then it seems that it is not out of the question that the heat stream from the Sun to the planets has as well periodical terms from the GHI but also terms from surface processes of the Sun from internal changing of the frequency shift, with no characteristic pattern, with minor effect.

>@ Ulric Lyons about CET.
The divergence you note (global versus CET), is not just with CET, and not only in the 1880`s either. It is because land surface temp`s are moving in the opposite direction to ENSO etc at certain scales.

Sorry Leif, you are clearly denying the data. The data is what suggests the mechanisms in physics, not vice versa.
Perhaps a tutorial is in order:
The solar wind pushes part of the Earth’s magnetic field back into a long tail. This stores energy in the tail. There is a boundary between field lines that are swept into the tail [we say they are ‘open’] and those that are not [we say they are closed]. Once in the tail the open field lines can reconnect and become closed again. This accelerates particles towards the Earth along the boundary between open and closed field lines. The particles collide with Nitrogen and Oxygen in the upper atmosphere which make those atoms glow and we observe aurorae. Under normal circumstances aurorae occur all the time at this boundary and we get what is called the ‘auroral oval’ situation near 67 degrees [magnetic] latitude. Once in a while, the solar wind is strongly enhanced by coronal mass ejections. The wind is compressed and the push on the magnetosphere is much stronger and the tail thickens as more and more field is pushed into it. This causes much more energy to stored, and the boundary, the currents, and the auroral oval move equatorward. If the push on the magnetosphere and the energy stored in the field is large enough, the auroral oval can move to mid-latitudes [and in extreme case even to near the equator] and then we record aurorae at mid-latitudes at the same time as strong magnetic activity is observed. The number and push of the CMEs depends on the solar cycle, being largest at solar maximum so the number of aurorae seen at mid-latitude is at a maximum when solar activity is at maximum, and at the same time great magnetic storms occur. Now, actually seeing the aurora depends on many other things than the aurora being there: weather, people’s awareness, number of observers and their motivation and interest. Observing the magnetic storms does not as the observatories record 24/7 all the time. So if a record of aurorae does not show a strong maximum at solar maximum, it simply means that the record is faulty or unreliable. This is well-known and there is no mystery about it.
To repeat myself:
See http://www.swpc.noaa.gov/Aurora/index.html [see also http://www.swpc.noaa.gov/pmap/ for current conditions]. From the link: “Being able to see the Aurora depends mainly on two factors, geomagnetic activity (the degree of disturbance of the earth’s magnetic field at the time) and your geographic location”. To see aurora below 55N you need a K-index of at least 7. The geomagnetic indices tell you when that happens so are a very correct and sensitive and objective measure of auroral activity [better than auroral sightings that are unreliable and uncalibrated]. And geomagnetic activity [when we have good and unambiguous records] since the 1840s shows no 60-year cycle. In my book that is enough to show me that your claim is spurious.
Study these links carefully. If you have questions or need clarification, please do not hesitate to ask.

As I have explained in the paper the Faroe aurora data were included because despite they are located at 62N people expert in aurora records have noted a strong similarity of these auroras with the mid-latitude auroras at <55N.
The aurorae may look the same, but their frequency of occurrence is not the same. If you ook at
http://www.swpc.noaa.gov/Aurora/globeNE.html you may note that the auroral zone is over the Faroe Islands for moderate geomagnetic activity [Kp=3]. These aurorae are not visible over Germany and England [for instance]. To see aurorae down there, you need a Kp in excess of 5 or 6. When that happens, the oval move so far south that you can’t even see it from the Faroe islands, so perhaps explaining why you infer the ‘inverse’ relationship. You see, it helps to know a little bit of the physics to understand what is going on, rather than hunting with Google to find explanations of straw men and fallacies. Simply google ‘aurora mid-latitude’ and you’ll find http://www.atoptics.co.uk/highsky/auror1.htm where you can learn more.
Schroeder here specifically reports on mid-latitude aurora in Germany: http://www.geofisica.unam.mx/divulgacion/geofinternacional/iframes/anteriores/2011/04/6_schroder.pdf
His conclusion:
“Here we present a previously unpublished historical observations of 171 auroras in Germany. We confirm that: Most auroras appear for Kp > 5, although some auroras are observed also with low Kp indices of 1 and 2. Maximum auroral occurrence is during the equinoxes and minimum during the solstices. Finally, maximum auroral occurrence is around the sunspot maximum and minimum around sunspot minimum.”

Aurorae in Denmark [which is mid-latitude; Copenhagen 55deg 40min] follow the sunspot cycle very nicely:

Figure 1 [red] sunspot number [blue] number of nights per year with aurora. Note the very large number in 1957. This is partly due to heightened awareness cause by the IGY [International Geophysical Year], showing how careful you have to be to interpret the ‘data’, especially if you don’t know much about the phenomenon they are supposed to describe.
To summarize: mid-latitude aurora are ordinary aurorae that can be seen at latitudes lower than the auroral zone because solar activity [maximizing at sunspot maximum] has perturbed the magnetosphere. The magnetic effects are a very good direct measurement of the auroral acitivity, using a compass needle instead of an eye, but no less direct and a lot more reliable.

This is exactly what Nicola is proposing. A variation in the Earth’s magnetic field that encourages mid latitude auroras at times of low solar output. How would the auroras be possible with a Kp index of 1 or 2?

The Denmark records look to show a 60 year trend as per Scafetta. One must allow for the extreme solar activity during 1957 over riding the background magnetosphere trend. Of interest would be the cloud formation patterns from 1940-1970 during the cool PDO phase if available. The PDO went into positive briefly around 1957 again showing the over riding factor of the extreme SC19, but the background forces still managed to keep the trend negative overall.

This is exactly the opposite of what Nicola claims.

Of 171 aurorae, only 4 were at Kp = 1 or 2. And Nature is noisy, so some small departures must always be expected.
The Denmark records look to show a 60 year trend as per Scafetta. One must allow for the extreme solar activity during 1957 over riding the background magnetosphere trend.
The Danish record shows that aurora occurs at maximum solar activity just the opposite of what Scafetta claims. The very large peak in 1957 is an artifact caused by increased awareness of the IGY. I can remember how the papers wer full of this and ask people to watch for and report aurorae.
The PDO has a well-known pattern of 30 cold and 30 warm periods, but that is not the issue. The aurorae, sunspots, and geomagnetic activity have not.

This is where you are perhaps not seeing the big picture. Scafetta has shown the 60 year pattern in the mid latitude aurora, sunspots or solar activity are working in conjunction with the overall modulation of the magnetosphere, so should be seen as a part contributor. The Kp index is only part of the story and does not report on other factors that might control the magnetosphere according to the theory. When looking at the aurora record of Denmark you need to keep this in mind, like other examples in the past where we need to combine solar and PDO records to match the temperature trends.

You can read can’t you. Read Schroeder’s paper. The exactly number is not important. A magnetic storm stores energy in the magnetotail, where it is released over the next ~48 hours.

He has shown no such thing. He maintains just the opposite of what observations and theory show. What he has convincingly shown is that his auroral dataset is unreliable.
The Kp index is only part of the story and does not report on other factors that might control the magnetosphere according to the theory.
We have a very good theory for what makes Kp and aurorae. There are no other factors.

You don’t need to combine records. They speak for themselves. And nobody is contesting that PDO is temperature related.

Leif,
as usual you are doing a great confusion and change topic everytime.
The aurora record patterns are not equal everywhere.
I am using the MID-LATITUDE full records at latitude <55N that is south of latitude 55N.
The data that I have used is the combination of all major available catalogs and it is here
http://www.ngdc.noaa.gov/stp/aeronomy/aurorae.html
The record from Denmark that you are using for supporting your claims is out of range. Denmark is northern than latitude 55N not southern of it ! See here
http://www.infoplease.com/atlas/country/denmark.html
Do not change the data as you wish. When you go norther than latitude 55N you start to see aurora strongly correlated to the solar activity, but the mid-latitude aurora visible at latitude lower than 55 behave differently.
Get it!

There is a negative (inverse) correlation of he Kp index (activity) to the measured (Climax) Neuton flux.
http://volker-doormann.org/images/climax_schroder.gif
There is no frequency visible of the Sun spot cycle^-1 in the hadcrud3 data, but a clear visible enhancement of the hadcrut3 temperature pattern in the time interval of the Sun spot number maximum, in respect to a pattern, which is in harmony with the solar tide spectrum from summarised synodic periods of planet couples.
This leads to refine the GHI from the solar tide functions with a fraction of the inverse Neutron flux. But this is still a minor and temporary effect in the forecast of the global climate function. The main impact for the terrestrial climate comes from the synodic frequencies of couples much slower that the sun spot cycle:
http://volker-doormann.org/images/ghi_jux2.gif
An important argument in the discussion of global warming and its nature, is the fact that the main global pattern of temperature proxies can be verified from well known solar tide geometries time coherent with the complex cycle of 2/1827 years^-1.
Today we are on one maximum of three that is slightly cooling since 1997 until 2063 and it will warm up until 2138 on a higher level than now. The begin of the next cool LIA will then be reached in 2704:
http://volker-doormann.org/images/ghi_23_2500m.gif
The importance leads from the recognition that the event of the LIA is a phase of a climate frequency which is well known also from Bond et al. (2001) for about 10 ky and is identified by me as a geometry from real moving objects in our solar system.
This recognition is different from all that stuff extrapolating short term parts of that long cycle with math functions out of the math books. And it is the beating argument against people who do extrapolate the global warming from human CO2 output curves.
These solar system geometries may simple lead to a precise climate forecast, but behind that geometries are still hidden processes, about the heat generation and the heat current from the Sun. But there are hints from the Neutrino capture rate from Homestake, and Japan that the fusion process in the Sun shows FFT frequencies, which are related to the planets.
http://volker-doormann.org/images/snu_rss_ghi8_2b.gif
Neutrinos are of interest, because they have no time delay trough the big Sun; this is in contrast to the photons, they need up to ~190 ky from the center of the Sun to the surface. And it may help to unterstand the physics behind this celestial heat system.

The record from Denmark that you are using for supporting your claims is out of range. Denmark is northern than latitude 55N not southern of it !
The Faroe Island record is not mid-latitude. and the occurrence of aurora does not change abruptly at 55N. And part of Denmark is actually below 55N [the southernmost is Gedser point at 54° 33′ 35″]. I am from Denmark and worked at the very Institute that compiled the data which I know very well. There is no sudden reversal of frequency right at 55° 00′ 00″. As you move from North to South the aurorae become rarer and you need more solar activity to see them. Here is a nice piece about aurorae in Denmark [and Iceland, Greenland]: http://www.dmi.dk/dmi/tr08-08.pdf some of the paintings shown in the article hang in my office. On page 86 you can see the oval and how it extended over Denmark during the famous Halloween magnetic storm in 2003.
Do not change the data as you wish. When you go norther than latitude 55N you start to see aurora strongly correlated to the solar activity, but the mid-latitude aurora visible at latitude lower than 55 behave differently.
It is just the other way around. Mid-latitude aurora are strongly dependent on the solar activity; at higher latitude that is no longer the case [at the auroral oval, aurorae are always present], at very high latitudes aurorae are even anticorrelated with solar activity as the auroral oval moves south. Let me quote Schroeder again on MID-LATITUDE aurorae in Germany:
“maximum auroral occurrence is around the sunspot maximum and minimum around sunspot minimum”.
Apparently you did not bother to consult and read the links I gave you on this. Your completely wrong assertion that mid-latitude aurorae are inversely related to the solar cycle undermines your paper and demolishes any scientific credibility you might claim. A good rule: “when in a hole, stop digging”.

In the auroral zone, aurorae are always present, regardless of solar activity. What Fritz showed was that at mid-latitudes aurorae occur at high solar activity. What Scafetta claims is just the opposite, namely that mid-latitude aurorae occur at low solar activity.

Fritz knew that the occurrence of aurorae in mod and low latitudes was qualitatively different, not that the aurorae were due to a different source. So, to summarize, Fritz knew that the occurrence of aurora at mid-latitude was contingent on high solar and geomagnetic activity. This is the opposite of what Scafetta claims. Perhaps we can get Nicola to confirm that Fritz was correct? That would a sign that he [Nicola] finally got it. My prediction is that Nicola will not do so, as this would invalidate his paper.

I don’t see that Fritz (as quoted above) and Scafetta conflict. Apparently at low solar activity magnetic shielding is weak so that particles from the occasional CME can more easily enter the magnetosphere and cause low-latitude aurorae. Scafetta apparently observes a 60 year cycle in these sightings.
Hell, if that doesn’t fit your theories, change the data!

Then look. Fritz [and I and everybody else who knows anything about this] say that there are more mid-latitude aurorae at high solar activity. Scafetta claims that at low solar activity there are more mid-latitude aurorae. How more opposite can the claims be.
Apparently at low solar activity magnetic shielding is weak so that particles from the occasional CME can more easily enter the magnetosphere and cause low-latitude aurorae. Scafetta apparently observes a 60 year cycle in these sightings.
The magnetic shielding is provided by the Earth’s magnetic field which does not vary with solar activity, so the number of mid-latitude aurorae depends on the number of CMEs. At solar max there are five CMEs per day. At solar minimum there is one CME every five days. So, a lot fewer and hence a lot fewer auroral sighting as observed. If Scafetta says otherwise, he is ignorant, mislead, cherry-picking, or worse. He is apparently using the same trick as Mann, making a composite time series [his Figure 2B] of data where some of the data is upside-down. I’ll give him the benefit of the doubt and ascribe this to ignorance. This does invalidate his paper.

The number of aurorae does not depend on the local magnetic field, but on the global field seen by the solar wind. And would not have any effect, anyway, on cycles shorter than ~100 years. The best description of auroral sightings over the last 500 years is that given by my friend Sam Silverman in http://www.leif.org/EOS/92RG01571-Aurorae.pdf written in 1992. He comments on the ~100-yr period [low activity near every century change]and notes [page 350] that “these observations imply that the Sun will probably shortly undergo a change in regime”, which the Sun apparently is doing. His Figure 1 is revealing. About periods he notes that very many peaks can be found in the power spectrum and that many of them are simply multiples of 11 years. Even mentions the disfavored planetary theory.

is irrelevant as the aurorae are not generated locally, but is a global phenomenon, generated way out in the magnetotail. If you carefully place yourself on both ends of a magnetic field line in the North and the South, you’ll very often see precisely the same aurora [part of the same current] at the same time.

November 14, 2011 11:05 am

Leif,
sorry but you are still mixing things.
Firts, the mid-latitude aurora records that I am using refer to latituie BELOW 55N. This include the aurora that were seen from North Africa to Germany, from Europe to Japan. Denmark is out this range.
I explained already why I also added the Faroe island record. Howeve, my claim was not based on that localized record, but on the mid-latitude aurora record that cover an extremely large region.
About the relation with the sunspot cycle and the temperature I have already explained that here we have two different patterns. The pattern related to the 11-year sunspot cycle to which the mid-latitude aurora annual frequency are usually positive correlated (and are positive correlated with the temperature) but a general correlation between the aurora data and sunspot numbertrend varies according the location and period: sometime they are positive correlated and sometime they are negative correlated about the smooth trending.
About the 60-year pattern the mid-latitude aurora record that I use appear to be negative correlated with the temperature 60-year pattern, as clearly shown in Figure 2.
Note that the things are quite different from your expectations. The things are complicated.
For example in 1880 the sunspot number cycle maximum was quite small the aurora number was not just small but extremely small, but the temperature on the Earth was at a maximum as predicted by the J/S conjunction. On the contrary in 1850 the sunspot number was at its maximum, but the climatic indexes were at a minimum. The same in 1960 when the sunspot number was at its maximum, but the temperature was decreasing since 1940 and in the 1960 was approcing its 60-year minimum.
As I clearly state in the paper several times there is also the possibility, that you are complitely ignoring in your reasoning, that solar irradiance and other solar/heliospheric indexes relevant for the temperature on the Earth do not follow exactly the sunspot cycle and your theories, as you are dogmatically supposing.
So, your definition of “low” and “high” solar activity defined on the sunspot number record is “relative” and not “absolute”. The above is a key point that you need to understand for not misinterpeting my reasoning and twisting my reasoning.
As I said before the data of the auroras are plotted in the figure 2 and the pattern is clear. We see three 60-year cycles from 1700 to 1900 and these cycles are negative correlated to the 60-year temperature cycle. Se also figure 3 that dates back to 1700 for climatic proxy models.
What matters for my paper is the common frequency set between aurora and temperature and the frequencies of Jupiter/Saturn orbits which implies the astronomical origin of the temperature oscillations. However, in the paper I am not arguing about a direct linear or monotonic positive correlated relashioship between the Aurora record and the temperature, I am just talking of a not well defined “link” between the aurora records and the temperature. Indeed, I am arguing about a more direct relashioship between the J/S configuration and the temperature, when J/S are closer to the Earth the temperature goes up and apparently the mid-latitude Aurora tend to go down: see also figure 7 in comparison with figure 2 and read section 5 and 6. I argue that when Jupiter and Saturn get closer to the Sun, less cloud form which cause a warming.
You are essentially mistaking my argument which is based of the aurora “frequencies” with an argument based on the aurora amplitudes and phases as if I am claiming that it is the aurora that cause the warming/coling cycles, that is not my reasoning, but your misinterpretation of it. So, try to understand my paper before misinterpreting it. A good starting point may be reading the title and the abstract.
Sorry, Leif. About my figure 2B both records are upside-down. So, no Mann’s trick there.
This is from the paper describing the Faroes data:
“Examination of the trends shows an initial decline to about 1877, a minimum period till about
1890, then an increase till about 1910, followed by a decline to about 1942, and an increase to 1960…..during the prolonged solar activity minimum from 1900 to about 1916 we get a maximum in auroral occurrence. …..The spectrum for the Faroes is very similar to that of mid latitude stations.”
So, dear Leif, there is an anticorrelation with the smooth trending of the sunspot number during that period about the Faroes auroras.
The things are more complicated than what you think, dear Leif!
Apparently, You are reasoning on the base of a theory that may be only partially correct.

“[…] H. Fritz. This author was already aware that the occurrence of aurorae in mid and low geographic latitudes was a qualitatively different phenomenon, that the very frequent occurrence of aurorae at latitudes of over 55 degrees would not characterize the level of activity of the actual causal source of aurorae, which were already known then, that the occurrence of aurorae at latitudes below 55 degrees is connected with geomagnetic storms at mid-latitudes and it is quite frequently time-related to the occurrence of extensive sunspot groups on the solar disk. “

weighted by the empirical factors: i.) 1.286, ii.) 1.0, iii.) 4.3, and iv.) 3.2 divided by 6 to fit in the plot range of the shown four single synodic tide functions.
Because the tide functions of this four couples are given from 3000 BC to 3000 CE, these data can be used to calibrate 14C data or other sample data of fewer accuracy than the astronomical data.
I think this reduces the science of climate forecast to a simple summation of the well known and published NASA ephemerides. The (war of the) heliocentric climate world view is opened.

Leif:
“The magnetic shielding is provided by the Earth’s magnetic field which does not vary with solar activity,”
Then why do cosmic ray counts and geomagnetic indices vary with solar activity?
Leif:
“so the number of mid-latitude aurorae depends on the number of CMEs.”
among other things.
Leif:
“At solar max there are five CMEs per day. At solar minimum there is one CME every five days. So, a lot fewer and hence a lot fewer auroral sighting as observed. ”
Accordingly, the five CME’s at solar max do not show up as mid-latitude aurorae, but the one per five days at solar minimum does, and the counts at solar min show a 60 year cycle. I agree that this is a remarkable claim, but if that’s what the data shows…

First, the mid-latitude aurora records that I am using refer to latitude BELOW 55N. This include the aurora that were seen from North Africa to Germany, from Europe to Japan. Denmark is out this range.
The range overlaps with Denmark, but that is not really the issue. The character of aurora occurrence in Denmark is not different from locations south of it. As I noted “Fritz [and I and everybody else who knows anything about this] say that there are more mid-latitude aurorae at high solar activity. Scafetta claims that at low solar activity there are more mid-latitude aurorae.”
So, do you disagree with the provider of your data that mid-latitude aurorae follow the sunspot cycle, with higher activity meaning more aurorae?
Sorry, Leif. About my figure 2B both records are upside-down. So, no Mann’s trick there.
Oh yes, because the Faroe data is anomalous as you realize with:
So, dear Leif, there is an anticorrelation with the smooth trending of the sunspot number during that period about the Faroes auroras.
Apparently, You are reasoning on the base of a theory that may be only partially correct.
The data, the data, shows that there is no anticorrelation for mid-latitude regions. And the theory was worked out 40+ years ago and has been confirmed by all observations since. You can study the theory here: http://www.leif.org/research/Geomagnetic-Response-to-Solar-Wind.pdf

Respectfully disagree.
-Your other Danish friends Svensmark and Christiansen also say that local cloud formation depends on the impact of cosmic rays at all latitudes.
– Friends Manoj & Maus from Potsdam not to mention Ryskin from Northwestern University, advise that there is a strong component of geomagnetic field generated by ocean currents, which along the Faroe bank are among strongest anywhere in the world, counter-gmf, directly affecting velocity of the warm currents across the nearby Greenland- Scotland ridge, and hence controlling surface temperature of nearby seas, to which local cloudiness/visibility would directly respond.
Non scientific person due to ignorance would dismiss most of those, but those scientifically inclined wouldn’t unless of course there is a particular reason to cloudy the issue.

You are still missing the point. The issue is that your concerpt of “high activity” is relative, not absolute. A “high activity” of what?
I do not discuss the origin of the auroras and their spacial distribution at the different locations.
About the Faroes auroras you are missing the point.
Let us for example suppose that the apparent anticorrelation observed between the Faroes auroras with the trending of the sunspot record is due to an incredible error of the guy that collected the data, and that the data need to be flip up-down so that the record fits better your theory.
The fact that you do not understand, dear Leif, is that even if you flip up-down the Faroe data record its power spectrum would show exactly the same peaks at about 10, 20 and 60 years and that these peaks are found in the temperature records. This is what really matters for my argument that the 10,20 and 60 year oscillations that we find in the temperature are not just an internal variability of the climate system but are due to astronomical forcings related to the oscillations of the solar system.
The fact is that whatever record of aurora you use even if you flip it up-down will approximately show frequency peaks at 10, 20 and 60 year if sufficiently accurate and long. Although the actual patterns may be in phase or out of phase with some trending of the sunspot number, which appears to be a fact that depends on the location of observation.
In other words,. dear Leif. you are not understanding the focal point of my paper whose title is “A Shared Frequency Set Between The Historical Mid-Latitude Aurora Records And The Global Surface Temperature”

Now how can we make more aurora at mid lat with less solar activity.
Lets weaken the earth’s magnetosphere my immersing it with less pos charges and add more neg charges (solar cycle is in low.) so ionization rate is less and less radially outward into interplanetary space. More interstellar neutrals inside the planetary spheres orbits. During high speed coronal hole wind streams interstellar neutrals and solar produced backwater get bull dozed right into Earth’s magnetosphere and snap, snap, snap then crackle pop.

High activity of solar magnetic field, and of electric currents in the magnetosphere and ionosphere.
I do not discuss the origin of the auroras and their spacial distribution at the different locations.
You do, e.g. ” A stronger solar or heliospheric magnetic field better screens galactic cosmic ray fluxes. Fewer cosmic rays reaching the Earth imply a weaker ionization of the upper atmosphere. As a side effect, less auroras form in the middle latitudes because a stronger magnetic field and a less ionized ionosphere mostly constrains the auroras in the polar region.”
I will grant you that the discussion is muddled and displays poor understanding of the physics, so in that respect you are correct: “there is no valid discussion of the origin etc…”
The fact that you do not understand, dear Leif, is that even if you flip up-down the Faroe data record its power spectrum would show exactly the same peaks at about 10, 20 and 60 years and that these peaks are found in the temperature records.

No, because you add the Faroe data to the end of another series. If you have, say three cycles of sin(t) and you add three more cycles of -sin(t), the resulting series has no single cycle.
In other words,. dear Leif. you are not understanding the focal point of my paper whose title is “A Shared Frequency Set Between The Historical Mid-Latitude Aurora Records And The Global Surface Temperature”
Looking at the frequencies alone is not valid, you have to look at the phase. What is important is that the series vary in phase not that you can find the same frequencies if the series are not stationary and the frequency peaks derive from different parts of the two series.
But we are losing track of the important point: looking at data is only important if the data is good, and your data is not. That leads you astray and into non-physical speculation. You can begin to do some damage control of your reputation by conceding that mid-latitude aurorae [as all the world agree with] are most frequent as solar maximum and are associated with strong magnetic disturbances. If you cannot do that, there is no hope for you.

No, because you add the Faroe data to the end of another series. If you have, say three cycles of sin(t) and you add three more cycles of -sin(t), the resulting series has no single cycle with a period of 2pi = 6.28.

http://www.leif.org/research/2pi-splice.png
Bottom line: the auroral, sunspot, and geomagnetic records do not show any consistent 60-yr oscillation, and especially not in the same time period as the climate [1850-2011]. The reviewers did a very poor job on you. Would you care to share their reports with us [if necessary ask their permission first]?

November 14, 2011 5:07 pm

Geoff Sharp, thank you.
There is no doubt that the data I use in the paper show a 60-year frequency peak. This has been found also by other people as I reference in the paper: so there are several peer reviwed paper talking about a quasi-60 year cycle in the aurora records.
The problem with Leif is that he uses the word “high solar activity” in a way that differs from what it is intended in the paper.
Let us see if I can explain it with an example. Let us suppose that the solar activity is made by a perfect and constant 11-year solar cycle. So, solar activity as Leif understand it is given by a perfect and constant cycle. Let us suppose that the top of the cycle is determined by a increased frequency of CMEs.
How would the aurora record look like? According Leif’s model one would see more aurora when the solar cycle is at its top of the cycle, that is when there are more frequent CMEs, and less auroras when the solar activity is at the bottom of the same cycle. The record of auroras will follow closely the 11-year CME cycle and we would see a perfect 11-year aurora record coupled to that cycle. I can agree with that.
Let us now add another ingredient to the model. Let us assume that there exists an additional component associated to the relative position of the planets. Let us assume that when Jupiter and Saturn get closer to the sun (with a cycle of 60-year) the physical properties of the heliosphere change in such a way that become more difficult or more easy for the aurora to form at a specific location.
It is evident that in such scenario the aurora record at each location would present an 11-year cycle in phase with the 11-year cycle of CME plus an additional 60 year cycle despite the fact that we are assuming that the solar CME activity is regurated by a perfect and constant cycle.
Essentially, Leif is thinking only in terms of frequency of CME, while I am thinking at the backgroud properties of the sun, of the heliosphere and of the magnetosphere too that may or may not be correlated to the multidecadal trend of the frequency of CME.
The major problem with Leif, in my opinion, is that he believes that the backgroud properties of the sun, of the heliosphere and of the magnetosphere are almost perfectly constant, so he does not grasp the point. Leif also believes that the sunspot cycle is a rigorous representation of what ever is happening in the sun, of the heliosphere and of the magnetosphere, while I don’t think so. The Sun and the heliosphere are a more complex system than just the sunspot.
One way to look at the things is to look at the mid-latitude aurora frequency number during the minimum of the sunspot solar cycle. Of course, during these minima we find less mid-latitude aurora than during the sunspot maxima. However, the mid-latitude records during the suspot solar minimum periods are not constant (as Leif’s solar model that has all minima equal would predict) but reveal a quite strong cyclicity as figure 2 shows. So becaue the number of CME events during the sunspot minima may be constant as Leif says because it may be strongly linked to the sunspot number, the strong cyclicity observed in the aurora is evidently due to a physical change of the solar/heliosperic background activity not elemenary linked to CME events alone.
My argument is that it is this solar/heliosperic background activity that is regulated by the planets and ultimately regulates the climate, not the CME events alone.
Of course the exact explanation of the physical mechanisms linking everything was not the topic of the paper. The paper simply stresses the fact that mid-latitude aurora records present the same major frequencies of the solar system and of the temperature. Then I correlate the temperature patterns to the planetary cycle directly, and in references I stress that the best mechanism is a cyclical modulation of the albedo.

Ulrich, Nicola displays a J/S tidal elongation at Earth diagram in figure 7A in his paper that clearly shows the 60 year oscillation (which happens to align with the PDO). Because Jupiter makes up the greater proportion of tidal influence his graph is also very close to the Sun/Jupiter distance graph that can easily be constructed with JPL data. This is a normal function that has probably been going on for 4.5 billion years.

However, the mid-latitude records during the suspot solar minimum periods are not constant (as Leif’s solar model that has all minima equal would predict) but reveal a quite strong cyclicity as figure 2 shows.
Mid-latitude aurorae are very strongly correlated with magnetic activity of which we have a very good record back to 1840s. The Faroe data in Figure 2 are not homogeneous [for whatever reason] and cannot be used as support as you claim. Figure 3 of Silverman 1992 [ http://www.leif.org/EOS/92RG01571-Aurorae.pdf ] show this clearly. As Silverman points out: “The solar activity minima in 1901 ans 1913 are refelcted here in sharp drops in auroral occurrence”. The unfortunate fact is that it is next to impossible to calibrate the auroral record, only the magnetic imprint of the very same currents that are the aurorae give a reliable picture.
My argument is that it is this solar/heliospheric background activity
We know now quite well the heliospheric magnetic field back to the 1830s [and the wind speed back to the 1840s] and there is no 60-year cycle in that data, nor in the sunspot number. It is very likely there is a 60-yr cycle in climate, after all the PDO shows one, but it is not caused by anything solar or heliospheric.
To clarify,please state here for the record that you now fully agree that mid-latitude aurorae follow the sunspot cycle and geomagnetic activity records.

November 14, 2011 6:05 pm

@ Leif that says “No, because you add the Faroe data to the end of another series. ”
It is not fully true Leif. I explain the things in the paper
In Figure 4 I am showing four power spectra.
4A is the power spectra of the temperature,
4C refers to the Mid-latitude aurora alone from 1700 to 1880,
4D refers to the Faroe aurora alone.
So, the two records mid-latitude aurora and Faroes are analyzed independly.
Then in Figure 5 I combine the spectrum of temperature record in 4A with the spectrum of the midlatitude aurora alone in 4C.
It is true that in 4B I show a spectrum obtained by combining the two aurora records, due to the fact that during the overlapping period from 1872 to 1900 the two records show comparable patterns. So I assumed that a continuity merging could be possible which assumes that the Faroes record could be used as a possible proxy for the mid-latitude record given the strong similarity between the two records from 1872 to 1966.
You may not like figure 4B, fine. But the argument in the paper was not based on it at all, Leif.
The aurgument in the paper was based on figure 4A, 4C and 4D and figure 5 that uses only 4A and 4C. I never used 4B to support the aurgument. of the paper. Think, Leif, think.
So, my argument is perfectly consistent. I am using the mid-latitude aurora record since 1700 and compare it with the temperature frequencies, as the title says. I can eliminatethe Faroes aurora from the paper and nothing would change, not even one augument.
A referee raised the issue that you are raising, I have explained it and my explanation was accepted because the referee realized that the Faroe record was not at all artificially altering the results, as you are misinterpreting, but was added for checking that the frequencies observed in the Mid-latitude aurora from 1700 to 1900 were also present in another long and more recent record of aurora that extended up to 1966.
On the contrary, I agree that the result depicted in figure 4B can be considered speculative because I merged the two records under the above continuity assumption that you may not like, but that figure does not change anything in the paper.
I am sorry Leif, but I believe that your hostility agaist me is so strong that you are trying to find the smallest aurgument in my paper that you may question instead of looking at the general findind and the correct logic of it. You are simply missing the point.
In conclusion, the Faroe auroras were added not for falsify the result as you are maliciously misinterpreting, but for checking that the same major frequencies found in the Mid-latitude record which ends in 1900, are present also for a more recent and independent long aurora record. That is what emerge from the paper and what the referee correctly understood.
In any case, Leif if you think that there are so many errors in the paper, or if you have better data why don’t you submit a comment to the journal so that I may properly respond?

November 14, 2011 6:48 pm

Hey, Leif
did you note that also Silverman that you like so much, which of course I referenced in my paper, agrees that a quasi 60 year cycle is present in the mid-latitude aurora record?
I appreciate that you are reading some of the references that I add in the paper.
Have you noted that Silverman analyzed the period 1500-1948 in figure 4 and found a rougth 55 year cycle (probable error +/-5 years).
However, note that before 1700 the data are very poor and he merged the mid-latitude catalog I used with another record (New England data base) to arrive to 1948 , which correspond to the arond 55N geomagnetid coordinate, so is at the border of the 55N.
He also found a rougth 83 year cycle. (Jupiter and Uranus 84 year resonance cycle?,what do you think?)
Then he wrote:
“The peak at 55 years had also been proposed by
Wolf [seeF ritz, 1893] as a prominent period.A definite and
clearly significant peak is found in the present data set at 33
years (that is my about 30 year cycle). CharvdtovaJakubcoevt [1988] have reported
periods in the range 60-100, 43-47, 34-37, and 30-31 years
in less well resolved spectra based on an auroral data set
coveting the interval 1001-1900 and the subintervals 1001-
1500 and 1501-1900. Except for the peak in the 43-47 year
period these are consistent with the present results.”
And I would say that Silverman’s results are compatible with mine too.
Are you convinced, Leif, that a quasi 60-year cycle in the aurora record was not observed by me only?
Of course the data are poor, but that is what we have.

November 14, 2011 6:49 pm

Nicola Scafetta says:

So, my argument is perfectly consistent. I am using the mid-latitude aurora record since 1700 and compare it with the temperature frequencies, as the title says. I can eliminate the Faroes aurora from the paper and nothing would change, not even one argument.
The point is that the auroral record is generally too poor for this, as it is not possible to calibrate it in a reasonable way. But it is also not necessary as the magnetic record is far better, directly giving us a measure of the electric currents in the upper atmosphere. And the magnetic record and the sunspot record do not show the 60-year period. Since the climate very likely does [PDO] it follows that that period must have other sources, if not just a random fluctuation.
In conclusion, the Faroe auroras were added not for falsify the result as you are maliciously misinterpreting
maliciously? that is a bit over the top, don’t you think?
your hostility against me is so strong…
I’m not aware of any hostility on my part. I have given your paper more analysis and thought than most and found it wanting. My beef is with the paper, not with the person. Try to count the number of negative words in your posts and mine and perhaps report here what you find in order to back up your assertion. If not, one can take that as admission that you have been too emotional and not quite polite.
In any case, Leif if you think that there are so many errors in the paper, or if you have better data why don’t you submit a comment to the journal so that I may properly respond?
If you think you have not responded properly here, I might just do that to give you a second chance. As a prelude to that and so that we don’t waste ink on it, please state here for the record that you now fully agree that mid-latitude aurorae follow the sunspot cycle and geomagnetic activity records in concert with the generally accepted view of auroral physics and all the modern data our marvelous space-based monitors have provided us with.

did you note that also Silverman that you like so much, which of course I referenced in my paper, agrees that a quasi 60 year cycle is present in the mid-latitude aurora record?
He notes that just about every period you can think up has been found by somebody at some time. “Scientists around the turn of the 19th century were busy looking for connections between aurora, weather, meteors, astronomical positions, and just about everything else.” I’m sure that you could find somebody claiming just about any period in the data. About the peaks he found he notes “The peaks here are, unfortunately, not sufficient well resolved to provide definitive information either to define the period with exactitude or for significance
Are you convinced, Leif, that a quasi 60-year cycle in the aurora record was not observed by me only?
Everybody analyzing the same crappy data one might hope will find similar things. That, as Silverman observes, cannot even be tested for significance.
Of course the data are poor, but that is what we have.
No, that is not the only thing we have. We have very good modern data for the past almost 200 years and they show no 60-yr period. Period.

Jeff, that is a slightly varying 11.86 cycle, and does not answer my question, which I was hoping for an answer from Nicola. Meanwhile, have a think about which of the 11.86yr and 19.86yr peaks in 7A/B could possibly be forcing the “cold” portion of this c.60yr cycle.
The theory is quite simple Ulric, greater gravitational/magnetic influence is directed towards our magnetosphere when the J/S position is closer to Earth, there can be no doubting of the JPL data. Nicola speculates that a change in cloud cover brought about by a density change in cosmic rays brings changes to temperature. If so I would not be surprised if this cloud cover change has an impact on spatial SST formations in the North Pacific (PDO) which have been shown to influence ENSO which is a contentious issue for some. A lot of correlations and perhaps the missing accurate data (cosmic rays/cloud cover) making the process harder but none the less worthy of investigation.

November 14, 2011 7:29 pm

Leif, the link between the aurora records and the sunspot cycle and geomagnetic activity records is “approximate” and needs to be well understood.
Note that our marvelous space-based monitors do not really exisisted when the aurora records used in the paper were recorded which also goes fur beyond the geomagnetic activity records. Moreover, what our marvelous space-based monitors record from the space may not be exactly identical to what people see or have seen from the ground as I wrote in the paper

It is very well understood, especially between auroral activity and geomagnetic activity. That you don’t understand it can be rectified. There are several good texts available. I can recommend ‘Exploring the Secrets of the Aurora’ by Syun-Ichi Akasofu, ISBN 1-4020-0685-3. It is very accessible and written by one the men who helped introduce the idea and concept of the auroral oval and how it is formed and moves.

What the modern data does is to show us that the theory is very well understood. What people have seen from the ground is, of course, unreliable: http://www.leif.org/research/Aurora-1570-01-12.png
The geomagnetic record is exquisite since the 1840s. It shows us directly the intensity of the currents in the ionosphere and even allows us to determine the properties of the solar wind with considerable precision. You can get a feeling for this by studying http://www.leif.org/research/IAGA2008LS-final.pdf

“The theory is quite simple Ulric, greater gravitational/magnetic influence is directed towards our magnetosphere when the J/S position is closer to Earth,,”
Not quite that simple, here is what he said:
“The strength of the magnetosphere is regulated by the sun (whose activity changes in synchrony with the planets), but perhaps the strength of the Earth’s magnetosphere is also regulated directly by the gravitational/magnetic forces of Jupiter and Saturn and the other planets whose gravitational/magnetic tides may stretch or compress the Earth’s magnetosphere in some way making it easier or more difficult for the Earth’s magnetosphere to deviate the cosmic ray.
So, when Jupiter and Saturn get closer to the Sun, they may do the following things: 1) may make the sun more active; 2) the more active sun makes the magnetosphere stronger; 3) Jupiter and Saturn contribute with their magnetic fiend to make stronger the magnetic field of the inner part of the solar system; 4) the Earth’ magnetosphere is made stronger and larger by both the increased solar activity and the gravitational and magnetic stretching of it caused by the Jupiter and Saturn.”
All a bit confused really, but the point is that these astronomical configurations (eg when Jupiter and Saturn get closer to the Sun) only last briefly, and so are to short lasting to physically represent the cause of the main warmer section of a 60yr cycle. And who is to say the tidal consideration (fig 7A) is valid anyway ?
From what I can tell, the response of surface temperatures to changes of the solar wind speed seem to be very immediate, the changes in cloud cover are a response to temperature change.

November 14, 2011 9:09 pm

@ Ulric Lyons:
The actual mechanisms are not fully understood yet, nor they were supposed to be the main topic of the paper. In the paper I propose some conjectures, not detailed physical proves of the chain of all single mechanisms. As somebody said above, science is full of misteries, and in this topic there are a lot of misteries yet. This is perfectly normal in science.
What the paper shows is that there are 60-year oscillations in the solar system. In the paper I focuses on three observable: one is related to the speed of the Sun relative to the center of mass of the solar system, one is related to the tidal envelop and another is a geometrical orientation. Thus, a lot of other observables would have such harmonic. These oscillations match with the observed climate oscillations.
So, we know that a 60-year modulation exists in the solar system. However, at the moment a full theory of how this oscillation is translated exactly into a forcing of the climate is not yet clear.
One of the topics of the paper was to show that even if we may not know the physical details of all involved mechanisms we can try to forecast climate change using astronomical cycles.
This is what people actually do for forecasting the ocean tides. Not all involved mechanisms are fully understood yeat about the ocean tides and people use harmonic model based of astronomical harmonics for overcome our ignorance.

I was also confused initially but see it pretty clearly now after Nicola pointed out the magnetosphere is affected by the planets as well as the Sun. I think you are getting confused about the brief period when J/S have their greatest effect. Yes there is a point of greatest modulation but it takes 30 years to reach that point before turning back to a baseline position 30 years later. It is not all about the min and max positions as any point in the 60 year period will be in front or behind the average.
Solar wind speed IMO does not have enough variation over the cycle as I have shown you previously.

Putting albedo changes after temperature could be one theory but I suspect you might be out on a limb, plus the earthshine project does seem to follow Nicola’s logic.

Here is how the scientific method works: You present a hypothesis based on some ideas and some data. The hypothesis predicts or posits the behavior of several related data sets.

If you want I can restrict it to that, but that is a red herring because there has not been any no matter what the latitude is. The data is challenged by noting that auroral activity which is notoriously difficult to calibrate is just a visual aspect of the underlying electric currents which are easy to measure via their magnetic effect. That is the proper procedure: decouple from the unreliable and unreproducible auroral sightings [why do you think the various auroral datasets stop shortly after 1960? because we realized it was not worth collecting that unreliable stuff, now that we have figured out the physics] and use the measurements of the currents.
There is more than one paper that disagrees with you.
If they are on the same shaky ground as Scafetta’s quantity does not matter. But, anyway, find me one that shows a 60-yr period in geomagnetic activity 1844-2011 and I’ll have a look.

Massive weaknesses in this paper. The suggested physical mechanism, as presented in this paper, of cosmic rays and clouds is NOT validly or reliably accomplished. Plausibility (IE the mechanisms well-reasoned details) is entirely lacking in the paper. Mechanisms MUST be girthed with plausibility when being thrown into a paper focused on solar/climate cycle matching. In my opinion, Scafetta’s paper is mortally wounded by such a failing.

Mid-latitude aurorae are very strongly correlated with magnetic activity of which we have a very good record back to 1840s. The Faroe data in Figure 2 are not homogeneous [for whatever reason] and cannot be used as support as you claim. Figure 3 of Silverman 1992
[ http://www.leif.org/EOS/92RG01571-Aurorae.pdf ]
show this clearly. As Silverman points out: “The solar activity minima in 1901 ans 1913 are reflected here in sharp drops in auroral occurrence”.

Again summing up solar tide functions of 11 couples from Mercury to Quaoar, one can identify a positive correlation between the number of auroras Silverman has published in Fig. 3 on a log scale and in comparison the square function of the GHI, what is visible in this graph:
http://www.volker-doormann.org/images/ghi_vs_aurora_silv.jpg
Because this summation only takes heliocentric tide functions of synodic well known 11 couples in our solar system, it means, if there is a correlation that the amount of solar tides related to the planets is connected with the amount of terrestrial aurora for the past 500 years, and as Silverman has pointed out that ‘drops in the auroral occurrence’ are connected to times when more solar nip tides occurred than solar spring tides.
Moreover, because the low frequencies of the slow moving synodic couples have obvious the greatest impact on the terrestrial auroras, temperatures etc. , the time length the tide configuration is present must have a relevant meaning in this mechanism of activity in the solar gas ocean on its moving surface.
A blow up of the hadcrut3 data 100 years ago do show also a drop in the global temperature and is corresponding to the solar tide function of six synodic couples (GHI6++ – Jupiter and outer planets):

The mid-latitude aurora is well represented by the observations from Denmark, which fully qualifies as mid-latitude [Scafetta even includes the Faroe Islands at 62N]. And what is there to say about this, except that they show what even Nicola claims he now understands, namely that the mid-latitude aurorae follow the sunspot cycle closely.
You could start with the data behind Nicola’s paper and if needed I am sure Nicola could provide other papers as referenced in his paper.
The data is of poor quality compared to the geomagnetic record of the electric currents of which the auroral sightings are but unreliable proxies. I know that auroral data very well, the records being stored in my very office at the Danish Meteorological Institute. We stopped recording the sightings in the late sixties because it was realized how useless an exercise it was now that we had the much better magnetic records. Here are the sightings record for several stations in the North Atlantic: http://www.leif.org/research/Aurorae-DMI-Nord.png . Note how dissimilar they are although looking at the same aurorae. Now, Scafetta claims that the auroral data after 1900 don’t matter for his paper, so they can hardly be any elephant in his room.

November 15, 2011 7:24 am

Geoff Sharp says:
November 15, 2011 at 3:06 am
The mid-latitude aurora is what Nicola is representing
And he uses the Faroe Islands data as representative of that. The data from Germany collected here shows the very close relation between auroral sightings and geomagnetic activity:
http://www.geofisica.unam.mx/divulgacion/geofinternacional/iframes/anteriores/2011/04/6_schroder.pdf
Returning to the Faroe Islands, note that the number of auroral nights at the height of the second largest solar cycle in 1947 is on par with those reported for some of the deepest solar minima, showing how unreliable the data is. Stations north and south of the Faroes show almost no aurorae at these minima. Silverman [his Figure 3] has compiled whatever data there is from mid-latitudes. His conclusion is plain: the decades 1900-1920 have very few aurorae in agreement with the geomagnetic record, so, effectively demolishing any claims to the contrary.
But, I think you have lost track of the issue, which is whether auroral sightings at mid-latitudes follow the solar cycle [as I and everybody else claim] or not [as Nicola claims].

In fact, he does cite Silverman. Here is the Silverman data [Fig.3] since 1800. http://www.leif.org/research/Silverman-Fig-3.png . Combined with what we know to be large auroral activity after 1950, it is clear that if there is any ‘cycle’ it is a 100-year cycle. So, no 60-yr cycle in mid-latitude aurora.

Here is the past 200 years of Silverman’s data about mid-latitude aurorae: http://www.leif.org/research/Silverman-Fig-3.png . Combined with our knowledge that the cycles after 1950 [19, 21,22] were large and thus had lots of aurorae, you can see there is not a 60-yr cycle, but, if any, a 100+ year cycle.

“I think you are getting confused about the brief period when J/S have their greatest effect. Yes there is a point of greatest modulation but it takes 30 years to reach that point before turning back to a baseline position 30 years later.”
Nonsense, what about the other two J/S synods in this supposed 60yr cycle ? Draw a 60yr sign wave and plot the other two synods and see how they fall on the negative portion of the wave. Now there is no logical reason why those two would be negative and the third one producing the whole positive portion of the cycle. And what of the 3 J/S oppositions within the 60yrs, is only the middle one more negative somehow ?
So how do we define “when Jupiter and Saturn are close to the Sun” ? IMO giving it as much as a 3yr window around the synod is stretching it.
“Solar wind speed IMO does not have enough variation over the cycle as I have shown you previously.”
Now that is a problem as solar wind speed it has a direct impact on auroras.

Mid-latitude aurorae only occurs during geomagnetic storms and those depend very little on solar wind speed. The real factors that determine the strength of a storm are the compression of the solar wind magnetic field and density combined with the occurrence of the field pointing southwards.

In order to get you on track early on, you should not calculate R^2 from moving averages. That is not statistically sound. If you have 100 data points, you can compute a moving average over say 5 points, which will give you 96 ‘data points’, but they are not independent, so R^2 [and various other tests for significance] is meaningless [much too high]. You can compute R^2 [and significance] from the 20 averages you would get from grouping the original data points into 20 consecutive intervals of 5 points. Any referee would reject the paper right here because of this, so don’t do this.

The underlying data is not smoothed as moving averages in time, so their smoothing does not matter. Repeat: any referee would reject the paper right here. If you need to smooth, calculate averages over adjacent [but non-overlapping] intervals. Do not correlate moving averages, that is a sure cause for rejection. I’m just saving you grief to come.

I still take issue with the penetration of interstellar neutrals crossing the orbital paths of the planets within the heliosphere, in particular whilst entering and exiting the frontal nose direction of the indented heliosphere bubble at equinox.

The Faroe data in Figure 2 are not homogeneous [for whatever reason] and cannot be used as support as you claim. Figure 3 of Silverman 1992 [ http://www.leif.org/EOS/92RG01571-Aurorae.pdf ] show this clearly.
There are power peaks shown in this paper of S.M. Silverman and he has identified the frequencies and the and the time periods from 5.6 years to ~83 years in Fig 4 and Fig 5.
The frequencies [1/years] of the aurora can be assigned to harmonic frequencies or synodic frequencies in the solar system of the planets Jupiter, Saturn, Chiron, Uranus, Neptune and Quaoarm, but also to the main frequency of the sun spot cycle of 1/11.196 y:

Period[y] f[1/y]
84 0.011903 = 0.011903 = 84y

55.6 0.01797 = 0.011903 + 0.00606832 = 0.01797 = 55.6y
UR + NE
33.3 0.03003 = 0.033947 – 0.00403089 = 0.029916 = 33.426y
SA - PL
24.45 0.0408998 = 0.033947 + (2*0.0034749)= 0.0408968 = 24.452y
SA + (2*QU)
18.2 0.054945 = 0.033947 + (6*0.0034749)= 0.054793 = 18.2y
SA + (6*QU)
14.81 0.067522 = 2*0.033947 = 0.067894 = 14.72y
(2*SA)
12.904 0.07775 = 0.084317 – (2*0.0034749)= 0.077367 = 12.92y
JU - (2*QU)
11.39 0.087796 = 0.084317 + 0.0034749 = 0.087792 = 11.39y
JU + QU
10.17 0.098328 = 0.084317 +(4*0.0034749) = 0.098216 = 10.18<y
JU + (4*QU)
9.41 0.106269 = 0.084317 + (2*0.0119032)= 0.108123 = 9.249y
JU + (2*UR)
8.60 0.11625 = 0.084317 + 0.033947788 = 0.118265 = 8.455y
JU + SA
8.0808 0.12375 = 0.084317 + (2*0.019700) = 0.123718 = 8.083y
JU + (2*CH)
5.56 0.1798 = (2*0.08931) = 0.17863 = 5.598y
(2*SS)

It is remarkable that the power of the slow moving synods is high, while the power of the synodic frequencies with the faster Jupiter are small. Also the half frequency of the object Chiron fits in this scheme.
This must not mean that there must be a mechanism were these couples of planets are involved, but it is remarkable that there are these relations, it links again the aurora periods to the planets in the solar system.

Nonsense, what about the other two J/S synods in this supposed 60yr cycle ? Draw a 60yr sign wave and plot the other two synods and see how they fall on the negative portion of the wave.
I think you will find it is not all about the J/S synod, you will notice a rough 10-11 year frequency in the peaks of Nicola’s figure 7A. When considering tidal forces Saturn is about 5% of Jupiter’s tidal force, thus the shape of Jupiter’s orbit can be more important than the J/S conjunction. Nicola and I differ on the orbital mechanics involved at this point but the data is still the same (JPL). I am of the view that both the Earth and Jupiter have the Sun as their orbit axis point and the Jupiter perihelion is controlled solely by planet perturbations with Saturn making up the majority of influence. My Jupiter/Sun distance graph shows that perihelion can occur at J/S conjunction and J/S opposition, which I think proves my point, but you may need to get clarification from Nicola.

The Schroder paper clearly shows that mid latitude aurora occur during times of low solar output. Of 171 aurorae 23% were observed with a Kp index lower than 5. You may prefer to rely on magnetic readings but it is clear there can be a disconnect, which is Nicola’s point.
Your claim that there is NOT a 60 year period in the mid-latitude aurora is still yet to be shown. I can see you will not analyze the data, so your claims will continue to be hand waving.

They precess over 40 synods: http://www.hps.cam.ac.uk/starry/keplerastrolmed.jpg
The last times the syzygies were closest to Jupiter perihelion was in 1702 and 1762. You may well find it was warmer around the 1730`s and 1790`s in that century.

The Silverman paper is interesting and backs up the Scafetta paper. Importantly it is necessary to only look at the data covering mid-latitudes. Two graphs in particular covering from 1700-1948 which cover the New England data (20,000 records taken over several hundred locations 41-45N) and the Fritz data that appears to be >55N show a clear 60 year period (the Dalton minimum has to be allowed for). The graphs agree with fig 2B in Scafetta’s paper.
Clearly the mid-latitude aurora record mentioned does NOT follow the sunspot or aa record of the era (with the exception of the Dalton).

Since today we know the physics and we have excellent data and therefore know that the aurorae follow very well the sunspot record, you can conclude that if an auroral record does not agree with this, then that record is faulty and unreliable. This is the point you and Nicola are missing.

Using R to histogram the years between 1700-1900 and then plotting the probability density, eye balling it, I get 3 gaussians 60 +- 10 years wide at half height.

The peak values are located at roughly 1720, 1780, and 1850 years.
The ratios of the peak values are roughly 1:2:3 (from right to left which is odd.)
The histogram is similar to figure B.
If you stand on your head and squint, you can see the 3 gaussians in figure B.

But then the relation breaks down, because at the next 60 year mark, in 1910, solar activity [and hence auroral activity] was at a very deep low. This is the usual fate of spurious relationships.

Mid latitude aurora are part of the magnetic reconnection process.
Makes you wonder if Jupiter or Saturn, both have polar Aurora and vortex, ever experience mid latitude aurora?
Now I have to wonder if the heliosphere experiences a quasi aurora of sorts.
Here’s why;
M. A. Dayeh et al. 2011 ApJ 734 29 doi:10.1088/0004-637X/734/1/29
SPECTRAL PROPERTIES OF REGIONS AND STRUCTURES IN THE INTERSTELLAR BOUNDARY EXPLORER (IBEX) SKY MAPS
M. A. Dayeh1, D. J. McComas1,2, G. Livadiotis1, R. W. Ebert1, H. O. Funsten3, P. Janzen4, D. B. Reisenfeld4 and N. A. Schwadron1,5
We study the spectral properties of different regions and structures in the energetic neutral atom (ENA) maps at energies from ~0.5 keV to ~6 keV from the Interstellar Boundary Explorer (IBEX) mission. We find that (1) an ankle-shaped break (spectrum hardens) between ~1 keV and ~2 keV characterizes the polar spectra and the right flank, while a knee-shaped break (spectrum softens) describes the ribbon, nose, and the front region spectra; (2) the spectral indices across full latitudinal range (tail and poles) comprise a dependence reflecting a knee break at mid latitudes and an ankle break at high latitudes. This latitudinal evolution has inflection points at ~40°S and ~36°N, and is strongly correlated with the solar wind speed structure obtained by the Ulysses/SWOOPS instrument during its fast latitude scan in 2007. Our study confirms that the ecliptic latitude predominantly orders the spectral signatures of ENA distributions. This ordering may reflect the average solar wind properties that vary characteristically with latitude around solar minimum. We report on the spectral analyses of six regions and two structures in the IBEX maps. We also discuss the spectral asymmetries between the north and the south polar regions, their correlation with solar wind measurements, and the implications of these observations. Thus, we show detailed connections between the IBEX energy spectra and latitudinal properties of solar wind.
Talk about vivid imaginations and wild ideas about the reconnection process, (not even I would have thunk this one). D McComas was on this team.
Local Interstellar Cloud -Local Bubble boundary as a possible source for the IBEX Ribbon
Grzedzielski, Stan; Bzowski, Maciej; Czechowski, Andrzej; Funsten, Herbert; McComas, David; Schwadron, Nathan A.
38th COSPAR Scientific Assembly. Held 18-15 July 2010, in Bremen, Germany, p.7
The brightest and most surprising feature in the first all-sky map of Energetic Neutral Atoms (ENA) emissions (0.2 -6 keV) completed by the Interstellar Boundary Explorer (IBEX) is an almost circular ribbon of a ˜ 140° opening angle, centered at (l, b) = (33° , 55° ) galactic coordinates and covering the part of the celestial sphere with the lowest column densities of the Local Interstellar Cloud (LIC). We propose a novel interpretation of the IBEX results based on the idea that the ribbon ENAs are produced by charge-exchange between the neutral H atoms at the nearby edge of the LIC and the hot protons of the Local Bubble (LB) rather than due to interaction of the heliosphere itself with the local interstellar medium. These ENAs from the LIC-LB interaction should be able to reach the Sun’s vicinity because of the thinness of the intervening LIC material. We show that a slightly curved interface layer of contact between the LIC H atoms (nH = 0.2 cm-3 , T = 6000 – 7000 K) and the LB protons (np = 0.005 cm-3 , T ˜ 106 K) might explain both the almost-circular shape of the ribbon and its observed ENA intensities, provided that the edge is < {500, 2000}AU distant, the LIC proton density (correspondingly) < {0.04, 0.01} cm-3 , and the LB contains ˜ 1% of non-thermal protons in the IBEX energy range. Secondary ENAs, which originate from a hierarchy of multiple charge exchange interactions between the energetic H atoms reentering the LIC from the LB and the LIC plasma should form an omni-directional globally distributed ENA flux which may be responsible for at least part of the high-energy signal observed by IBEX. The new ideas presented here about the LIC-LB sources of ENAs are totally independent of the existing heliospheric models. If these ideas are correct, IBEX may provide a way to determine the distance to the LIC edge and a means to determine the plasma conditions in the LB.
I wisht the planetary theorists would take alook at the bigger picture.

There are 20,000 records from several hundred stations behind just one of the graphs listed. These are not derived from news paper clippings but from a much more reliable source according to Silverman.
Data for New England were taken from a compilation by
S. M. Silverman based on several sources (for a description
of observational systems from the end of the eighteenth cen-
tury to 1870, see Fleming [1990]). The primary source used
here was the meteorological registers kept by voluntary ob-
servers in the network established by the Smithsonian Insti-
tution and continued, primarily, by the Army Signal Service
and the Weather Bureau. Observations were also published
in the Monthly Weather Review and in the series, Climato-
logical Data of the United States. Some additional data for
individual locations were also used, as, for example, the
observations of Bentley in Jericho, Vermont, from 1881 to
1931 [Silverman and Blanchard, 1983]. Some data were also
taken from the auroral catalogs published by Lovering [ 1866-
1871] and Fritz [1873]. The New England data base com-
prised about 20,000 records, from 1741 to 1948. Some scat-
tered records prior to 1741 exist but are not utilized here.
Altogether several hundred locations are involved. Their geo-
graphic coordinates range from about 41 ø to 45 ø , and the
corresponding corrected geomagnetic coordinates from about
53 ø to 57 ø .

This is as expected as the mass flux is largest near the equatorial plane [makes no difference if you use ecliptic latitude instead]. So a prediction will be that the ribbon will disappear in a couple of years when we are just past maximum and the solar wind is much more uniform in latitude.
Now, all of this has no impact on the sun, solar cycle, earth, climate, etc.

That is so for the records after about the 1880s, but not before.

It would, but there is no guarantee that it will be recorded correctly. The major argument about the unreliability of the auroral record is that aurorae have a magnetic signature which is objective and observable 24/7. We have good magnetic records back to the 1830s and those clearly show great discrepancies with the auroral records, testifying to the unreliability of the latter. Apart from the disagreements between the individual auroral records. The magnetic record on the other hand never has any disagreement between stations as magnetic storms are worldwide. As we learned about the connection between aurorae and magnetism [discovered in 1740s] and figured out the physics after the IGY in the 1950s and 60s, we stopped keeping track of the aurorae as it was realized that such a record could not be made reliable, and was now not needed any longer as the it was just a poor proxy of the magnetic record. In spite of your statement of being open to this, I don’t think you really are, as you have already been shown many examples and explanations of why the record is no good.

As Silverman points out, even an imperfect and flawed record can be useful for times where we have no other data, as we often will be able to correct or compensate for the flaws [based on our modern understanding of the physics behind the record]. E.g. as Krivsky and Pejml did with their ‘civilization factor’. But to use the raw record will often get you in trouble, like Scafetta got, when he was speculating on why there should be more aurorae at solar minimum [there aren’t].

Because one record doesn’t agree with another is no reason to call one unreliable. The aurora record as seen can occur when Kp values are low, there is probably a valid reason which Nicola has touched on that may have other downstream effects on climate etc. If one portion of the planet experiences an aurora while the planet average Kp value is low may just mean that portion of the planet is experiencing a localized phenomenon. What if that area of the planet was a large area in the North Pacific that stayed cloudless for an extended period of time? Perhaps the beginning of an understanding of why the PDO occurs? Agreed the evidence is flimsy right now, but certainly worth investigating.

Lots of good reasons. They are both unreliable. Even a single record can show its unreliability [even if it is an average of many stations]. A single look at Silverman’s record for 1800-1948 shows this so clearly: http://www.leif.org/research/Aurorae-1800-1948.png
The green ovals outline particularly crass discrepancies between the sunspot number [red] and the auroral record. Critical here is, of course, that aurorae follow the sunspot cycle, but that we know they do from modern observations.
The aurora record as seen can occur when Kp values are low
No, not at mid-latitudes. In the very few cases that occurs, there was a magnetic storm the day or two before and it can take a few days for the effects to die down. So, the monthly or yearly count will still show a strong relationship between Kp and mid-latitude aurorae.
If one portion of the planet experiences an aurora while the planet average Kp value is low may just mean that portion of the planet is experiencing a localized phenomenon.
Mid-latitude aurorae only occur as a global phenomenon. They are the result of particles accelerated tens of thousands of km above the Earth and the magnetic effects from the currents are world-wide. Here are magnetograms from stations all over the world [the map shows where they were] during the great storm of 2003 that created widespread aurorae: http://www.leif.org/research/Halloween-Storm-Magnetograms.png
What if that area of the planet was a large area in the North Pacific that stayed cloudless for an extended period of time?
This has nothing to do with the aurora.

November 16, 2011 7:31 pm

@ Leif
you are making a lot of confusion.
Arguing that the data are wrong just because they do not fit your personal theory is a quite weak argument. All historical aurora records that we have are sufficiently correct for the purpose of my paper.
However, there is no disagreement among the records as you claim. The fact that some of them present a reciprocal negative correlation on the multidecadal scale is perfectly normal and in perfect agreement with what I say in the paper.
Your confusion is just due to the fact that in the paper I address only the Mid-latitude auroras from Europe and Asia plus the Faroes ones that match with the Mid-lat aurora. I did not discuss in details the other northern and american records because it would have made the paper much longer and it was useless for the purpose of the paper. The resason is because according to the resoning on my paper they could present a reciprocal behavior, if you think well.
About your argument based on magnetograms, it is naive. Tell me, when there is a Earthquake does everybody on the Earth notice it with his senses? Of course all machines around the world notice it. The same is with the aurora, everywhere the machines detect a signal , but only in specific regions the aurora can be see from the surface.
Sorry Leif.

Let us try this from a different angle: you agree that if a strong aurora is seen in mid-latitude over Europe and Asia, there will be a magnetic signal everywhere. This means that such a strong magnetic signal is a good indicator of an aurora in that region [actually in any mid-latitude region – but let that slide for now] and that therefore the magnetic record is an objective, reliable indicator of mid-latitude aurorae, right?

The particles follow field lines, don’t make the magnetic field lines. So ‘defining’ has to be thought of more precisely.

I devised the North Atlantic precursor more than a year ago, and havn’t written anything yet. Reason is that it in some parts it ‘follows’ closely the shape of the solar output, but only if it is delayed by number of years. Found similar with fluctuations of the Arctic magnetic field.
Only conclusion could be an external force (for both sun and the Earth) acting on the core, but in the case of the sun it takes much longer to propagate to the surface.

Of 171 recorded aurora, only 4 were at low Kp at the time of the aurora, but the day before there was a geomagnetic storm, so Kp is still the indicator in all cases.

23% of all 171 records in Schroder’s study occur when Kp index is less than 5 (ie 4 and under) The records are taken all over Germany which has a latitude less than 55. I have included a link to the original table so those interested can see how many of those records occur just after high activity. Leif has stated that mid latitude aurora only occur at a Kp index of 7 or above which is clearly wrong, he also stated the low Kp values with aurora are directly after high Kp days which is also mostly wrong. I encourage people to look for themselves. It is obvious that the Kp value is not the only value important when dealing with mid latitude aurora.

23% of all 171 records in Schroder’s study occur when Kp index is less than 5 (ie 4 and under) The records are taken all over Germany which has a latitude less than 55.
The smaller the latitude the higher must Kp be for aurora to occur.
The Kp=7 value comes from http://www.swpc.noaa.gov/Aurora/globeNE.html
It is obvious that the Kp value is not the only value important when dealing with mid latitude aurora.
It is not that Kp creates the aurora, but that statistically high Kp and midlatitude aurorae go together.
http://www.swpc.noaa.gov/Aurora/#kpmaps
Magnetic Latitude Kp
66.5 0
64.5 1
62.4 2
60.4 3
58.3 4
56.3 5
54.2 6
52.2 7
50.1 8
48.1 9
The Northern part of Germany has magnetic latitude 50 degrees, so Kp needs to be 8 or greater to have an aurorae overhead, but because of the great heights aurorae go to, you can now and then see one several hundred kilometers [several degrees] to the Nord. So, occasionally, a very extended aurora can be seen at somewhat lower Kp. You are misinterpreting Schroeder’s result. Read his last line: ” Finally, maximum auroral occurrence is around the sunspot maximum and minimum around sunspot minimum.” and “Figure 2 and Table 2 show that maximum numbers of auroras were observed around the maximum sunspot number years: 1947 and 1957-58. Minimum numbers of auroras were observed around the years of minimum sunspot numbers: 1952-54 and 1963-64; moreover, these events were mostly faint and short-lived. Thus, even in case of low solar activity, auroras may appear, but their occurrence frequency is very low.” That is the important point. “The connection between the appearance of auroras and geomagnetic activity (represented in the present report by the Kp-index), is well known (e.g Newell et al., 2009). There is an experimentally confirmed relation in the sense
that in the case of a higher Kp-index, auroras can be observed at more southern regions”.
So, bottom line: auroral activity at mid-latitudes follow the sunspot number and geomagnetic activity. This becomes even more apparent if yearly counts of the aurorae are used, as the inevitable noise decreases.

Your arguments have not proven to be substantiated.
1. Mid latitude aurora do not follow a 60 year period. FALSE.
2. Mid latitude aurora only occur above 7 Kp. FALSE.
3. Mid latitude aurora appear at low Kp only when a geomagnetic storm is experienced the previous day. FALSE.
4. Mid latitude aurora follow the sunspot number. FALSE.
Nicola’s research is vindicated and displays that all is not known when it comes to mid latitude aurora.

This is not my argument, but the result of decades of work by many scientists. Some of the [few] cases you have brought up are just the noise in the system. Schroeder again:
“Finally, maximum auroral occurrence is around the sunspot maximum and minimum around sunspot minimum.” and “Figure 2 and Table 2 show that maximum numbers of auroras were observed around the maximum sunspot number years: 1947 and 1957-58.

Nicola’s research is vindicated and displays that all is not known when it comes to mid latitude aurora.
His claim that mid-latitude aurorae occur most frequently at low solar activity is nonsense. Both observation and theory show this.

@ Leif
Sorry Leif . You are competely misinterpreting my point.
First, I never denied in the paper and above that the aurora records present a decadal cycle in positive correlation with the decadal solar cycle. If you read above the initial comment to the article I clearly wrote
“During the solar cycle maxima the magnetosphere gets stronger so the aurora should be pushed toward the poles. However, during the solar maxima a lot of solar flares and highly energetic solar explosions occurs. As a consequence you see an increased number of mid-latitude auroras despite the fact that the magnetosphere is stronger and should push them toward the poles.

Which may not be very elegantly written, but clearly implies that I am saying the Mid-latitude aurora present a decadal cycle in positive correlation with the decadal solar cycle.
On the contrary my point is different and regards the 60-year modulation. Above I wrote “On the contrary, when the magnetosphere gets weaker on a multidecadal scale, the mid-latitude aurora forms more likely, and you may see some mid-latitude auroras even during the solar minima as Figure 2 shows.”
Second, Now let us look closely at your german record
http://www.geofisica.unam.mx/divulgacion/geofinternacional/iframes/anteriores/2011/04/6_schroder.pdf
This record covers the aurora from 1946 to 1964 and cover two solar cycles. Now you need to understand that from 1940 to 1970 my 60 year cycle was decreasing. According to what I wrote in the paper you need to look mostly at what is happening during the solar minima. From the paper of above the solar minima periods 1951-1954 and 1961-1964 where almost equivalent about the sunspot number. Also the aa index was almost equal during these two periods.
According your understanding of this phenomenon the two periods should be approximately equivalent about the aurora events. And aurora could be seen only at Kp>=8.
However, according my understanding of this phenomenon, because the 60-year cycle was in its decreasing trend, the solar minimum period 1961-1964 should have recorded more auroras than the previous solar minimum period 1951-1954. Moreover, the solar minimum period 1961-1964 should have recorded more aurora with a lower Kp index than the previous period 1951-1954.
Now, let us see the data to see which theory (yours or mine) is confirmed.
These are the recorded aurora from 1951 to 1954
Xp
01/05/51 7
02/05/51 7
25/09/51 8
07/10/51 8
28/10/51 9
These are the recorded aurora from 1961 to 1964
Xp
08/01/61 4
04/02/61 7
17/02/61 6
26/05/61 4
17/07/61 6
11/08/61 5
11/10/61 4
28/10/61 3
10/01/62 6
29/06/62 3
28/07/62 4
24/10/62 5
29/07/63 3
30/07/63 5
03/10/64 4
As you can easily see from the above numbers, the data agree with my expectations, not with yours. In fact, not only in 1961-64 we see much more german aurora than during the period 1951-1954 as my model predicts, but we often see them also with a very low Xp index 3, 4, 5 and 6 and always below Xp=8 which do not fit at all your theory of Xp>=8 for Germany (not even with the several hundred kilometer hypothesis jump, which should be more than 1500 Km to cover the 10 necessary degrees).

“During the solar cycle maxima the magnetosphere gets stronger so the aurora should be pushed toward the poles.
No, that is not the expectation. First, what do you mean ‘magnetosphere gets stronger’? Second, during maxima the auroral zone should be pushed towards the equator by the geomagnetic storms [as observed].
However, during the solar maxima a lot of solar flares and highly energetic solar explosions occurs. As a consequence you see an increased number of mid-latitude auroras despite the fact that the magnetosphere is stronger and should push them toward the poles.
Here you repeat the wrong physics.
Which may not be very elegantly written, but clearly implies that I am saying the Mid-latitude aurora present a decadal cycle in positive correlation with the decadal solar cycle.
It is dead wrong, rather than not just very elegant. Since that implies that geomagnetic activity shows the same solar cycle, the aurorae should follow geomagnetic activity [as they do] which therefore becomes as good indicator of aurorae [as observed].
On the contrary my point is different and regards the 60-year modulation. Above I wrote “On the contrary, when the magnetosphere gets weaker on a multidecadal scale, the mid-latitude aurora forms more likely, and you may see some mid-latitude auroras even during the solar minima as Figure 2 shows.”
Except that the ‘magnetosphere does not get weaker’, it contains more energy at solar maximum, and now you between to contradict yourself. From the above one concludes that you think that at solar minimum the magnetosphere ‘gets weaker’ [since it gets stronger at maximum] and that therefore mid-latitude aurora forms more likely. The opposite is observed, there are very few and weak mid-latitude aurorae at solar minimum
This record covers the aurora from 1946 to 1964 and cover two solar cycles.
The same pattern is seen in all solar cycles, not just those two. The number of aurorae during the minimum years are so low that you cannot make any meaningful statistics on them. The meaningful comparison is between the low number of aurorae at minimum vs. the high number at maximum. This fact is observed in every cycle and is well-understood. Schroeder emphasizes that repeatedly: “Finally, maximum auroral occurrence is around the sunspot maximum and minimum around sunspot minimum.” and “Figure 2 and Table 2 show that maximum numbers of auroras were observed around the maximum sunspot number years: 1947 and 1957-58. Minimum numbers of auroras were observed around the years of minimum sunspot numbers: 1952-54 and 1963-64; moreover, these events were mostly faint and short-lived. Thus, even in case of low solar activity, auroras may appear, but their occurrence frequency is very low.” That is the important point. “The connection between the appearance of auroras and geomagnetic activity (represented in the present report by the Kp-index), is well known (e.g Newell et al., 2009). There is an experimentally confirmed relation in the sense that in the case of a higher Kp-index, auroras can be observed at more southern regions”.
And this is not my theory. It is everybody’s theory, and a generally accepted FACT. Figure 3 of Silverman shows this clearly. BTW: You keep evading my question:
Again: please state here for the record that you now fully agree that mid-latitude aurorae follow the sunspot cycle and geomagnetic activity records in concert with the generally accepted view of auroral physics and all the modern data our marvelous space-based monitors have provided us with

Progress is slow because comments are too long. So, let us take a slower pace. Start with that statement of yours. ‘magnetosphere gets stronger’. What is that? Which magnetosphere? How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
Just answer this and nothing else in order not to gum up the process.

If the planetary theory is to be taken seriously [as a major driver] it must work at all times. If the theory is only a weak modulation with almost no effect, one can allow intermittent failures.

We’re only talking of a ~1% variation in surface temperature over periods of many thousands of years. The causes and their periodicities are quite subtle and hard to tease out of the noise. One man’s “weak modulation” is another’s strong evidence.
Leif Svalgaard says:
For 1700-1900 there is a weak 60-yr period [in the red box] and Scafetta picked that up, but the point is that the relation fails outside of the red box while the planets just cycle on with no failures. So, the claim of planetary cycles determining cosmic ray flux [or solar activity or aurorae etc] is spurious

Longer term cycles will alter the appearance of the interaction of shorter term cycles as they manifest in various indices. This does not mean they ‘disappeared’ outside certain timeframes.
Nicola Scafetta is wise to study a broad spectrum of phenomena. Nature moves in many mysterious ways.

The really big discoveries come not from incremental discovery but from the left field and an unexpected and particularly close correlation is worthy of a detailed study. Not to say this is one of them, but by arbitrarily dismissing it as you have done is scientific arrogance at its worst.

Sorry, Leif.
Science is not done by simply looking at the textbooks, as you understand. Science is done by looking at the data. You continuously claim that when the data contradict your theory, or the textbook theory of your old books, then the data are wrong in some way. And you do this even by using ridiculous claims such as that from central Germany people were able to see auroras happened above Iceland or north Norway, which is what your theory would require to see aurora with XP=3 from Germany!
About Figure 3 of Silverman you need to understand that Silverman attached the north american New England aurora (1800-1966) to the mid-latitude aurora from Europe and Asia (1500-1800). This operation cannot be done because the north american New England aurora have the same characteristics of the aurora from Iceland which are negative correlated (about the 60-year cycle) to those of central/south Europe.
If you look only at the mid-latitude auroras the 60-year pattern is not disrupted at all as my figure 2 shows: a fact that it is further confirmed by your german auroras

About Figure 3 of Silverman you need to understand that Silverman attached the north american New England aurora (1800-1966) to the mid-latitude aurora from Europe and Asia (1500-1800).
should read: the New England mid-latitude aurora to the mid-latitude aurora from Europe and Asia.
This operation cannot be done because the north american New England aurora have the same characteristics of the aurora from Iceland which are negative correlated (about the 60-year cycle) to those of central/south Europe.
You are claiming here that New England mid-latitude aurora are negatively correlated with those of central Europe [forget south – as there are too few aurorae seen there]. Silverman says [page 340]: “Data for New England, available only from about 1740, show a behavior similar to that of Europe”. And everybody knows [well, it seems, almost everybody] that this is indeed the case. When the oval expands to reach mid-latitudes in Europe during a magnetic storm lasting a day or more, that very same oval is seen in New England six hours later as the Earth rotates under it. Massachusetts is just south of the Kp=7 line [statistically] as is Northern Germany.
To get a feeling for the situation take a look at the predicted [based on experience] auroral activity for Europe and North America during the geomagnetic storm of 2011/09/26 [Kp reached 6+]: http://www.meteorwatch.org/2011/09/26/auroras-over-the-uk/ Note how New England and Central Europe have very similar probabilities [as they should].

It is amazing you can be so blind [one wonders why?]. Because your ’60-year cycle was in its decreasing trend’ [see your Figure 2], the solar maximum period 1946-1949 show have recorded more aurorae than the 1951-1954 period. Let’s look at the German data: 1946-1949 65 aurorae, 1951-1954 only 5 aurorae. So ‘your understanding’ is clearly grossly lacking.

There very likely is a causation, it was the correlation that failed [Hathaway picked the wrong peak]. And he has not lost his reputation at all. Making a mistake and acknowledging it is quite OK and does not ruin your reputation. Clinging to a theory long after it has been shown to be a failure and especially if based on shaky physics, is the reputation-killer.

Leif,
I am sorry but you do not understand the issues addressed in my paper. You need to be more humble and try to listen carefully and think better without all this ridiculous angriness and obtuseness that you have that makes you blind to the evidences.
1) I never said that during the 11-year solar cycle maximum we see less aurora than during the 11-year solar cycle minima. This is what you are saying. I am talking about another cycle and mechanism. So, do not twist what I say.
2) the New England auroras in North America are not compatible to the mid-latitude auroras in central Europe for the simple reason that you need to look at the position of the magnetic north pole which is located north Canada and it was located even more inside Canada 100/200 years ago. So, the north Magnetic pole is and was much closer to Massachusetts than to Germany by at least 10/20 degree which makes Massachusetts auroras compatible with Iceland auroras, as I said in particular in 1800 and 1900.
In the paper I use the catalog of Mid-latitude auroras from Europe and Asia. which is the appropriate catalog that needs to be used for my purpose, and my figure 2 shows how those data look like. The catalog that I use is an update that occurred “after” Silverman published his work and the data were not mixed with the American New England Catalog for a clear reason: the latter catalog shows an anticorrelation about the 60 year cycle with the European Mid-latitude.
That is, about the 60 year cycle the American catalog shows a maximum in 1880, while the European Mid-latitude show a maximum in 1850 and a minimum in the 1880s , for example. The same anticorrelation is repeated with the Faroes auroras and the Iceland auroras from 1900 to 1960. So in the data there is an evident dynamics that you do not understand regarding the sensitivity of the upper atmosphere to auroras that changes in time, and it is not constant as you think.
The catalog of German Auroras that you have referenced confirms in full my expectations and contradicts your theory quite fragrantly. You still need to explain why from Germany a lot of aurora with Kp index of 3 and 4 were seen during the solar minimum 1961-1964.
So, I cannot but invite you to be more humble on issues that you clearly do not undertstand.
Because you are also not interested in having an educated and constructive discusssion on this issue (as well as on any issue I need to say), there is no need for me to continue this discussion with you.
Sorry, Leif.

1) I never said that during the 11-year solar cycle maximum we see less aurora than during the 11-year solar cycle minima. This is what you are saying. I am talking about another cycle and mechanism. So, do not twist what I say.
You are saying that during low solar activity we see more aurora than during high activity. We don’t. E.g. according to our ‘other cycle’ there should be more aurora 1951-1954 [there were 5] than during 1946-1949 [there were 65]. And ‘another mechanism’. There is no other mechanism. Aurorae are well-understood.
2) the New England auroras in North America are not compatible to the mid-latitude auroras in central Europe for the simple reason that you need to look at the position of the magnetic north pole which is located north Canada and it was located even more inside Canada 100/200 years ago. So, the north Magnetic pole is and was much closer to Massachusetts than to Germany by at least 10/20 degree which makes Massachusetts auroras compatible with Iceland auroras, as I said in particular in 1800 and 1900.
The magnetic pole that the aurorae are organized by the ‘corrected geomagnetic pole’ and one can calculate magnetic latitude [90-distance from corr. geomagn. pole] for New England and for Germany. In 1800 they were equal [=54 degrees]. in 1900 they were three degrees different. New England was at 55 degrees in 1900, Iceland was at 67 degrees, so not at all the same.
In the paper I use the catalog of Mid-latitude auroras from Europe and Asia. which is the appropriate catalog that needs to be used for my purpose, and my figure 2 shows how those data look like.
After 1900 you use data for the Faroes which are at corrected geomagnetic latitude 62 degrees, so not at all mid-latitude.
New England Catalog for a clear reason: the latter catalog shows an anticorrelation about the 60 year cycle with the European Mid-latitude.
No, the Mid-latitude New England data does not show a variation different from European Mid-latitude. Silverman [page 340] stresses that “Data for New England show a behavior similar to that of Europe”.
So in the data there is an evident dynamics that you do not understand regarding the sensitivity of the upper atmosphere to auroras that changes in time, and it is not constant as you think.
What the data shows is how poor the auroral record is. The sensitivity of the upper atmosphere to aurorae does not change in time as the particles don’t know what time it is. Auroral physics is very well understood.
You still need to explain why from Germany a lot of aurora with Kp index of 3 and 4 were seen during the solar minimum 1961-1964.
First, it was not a lot [grand total of 7]. Second according to your ’60-yr’ cycle there should have a lot fewer aurora in 1946-1949, yest there were many more [65 of them]. And as I have pointed out sometimes the aurora appears during a magnetic storm that may last a day or two [not necessarily at the height of the storm], as you can see here http://www.leif.org/research/Kp-1961 where I have marked the few aurorae with Kp less than 5 during 1961..
So, I cannot but invite you to be more humble on issues that you clearly do not understand.
When it comes to aurorae and geomagnetic activity I am the expert here. This is my field.
Because you are also not interested in having an educated and constructive discusssion on this issue (as well as on any issue I need to say), there is no need for me to continue this discussion with you.
I have patently and carefully discussed the issues [and shown you wrong at every turn so perhaps you don’t want to consider it constructive], which shows my great interest in your work. I don’t think anybody has shown similar or more interest. I can also understand why you throw in the towel.

November 19, 2011 4:45 pm

Sorry Leif,
You continue to denying the data to defend your prejudices. The data that I used are corrected enougth and show the patterns that I found.
About the relation between the American New England region and the central mid-latitude central south Europe region you may give a look at the Magnetic Field Total Intensity in 2010
http://www.ngdc.noaa.gov/geomag/WMM/data/WMM2010/WMM2010_F_MERC.pdf
It is evident from the figure that the New England region, which is located between 50000 F and 55000 F, is magnetically equivalent to Iceland, not Germany.
In 1800 and 1900 the magnetic field lines in america were even deeper toward south because the magnetic pole was much more toward Canada. In fact in 1990 this was the magetic field and you can see
http://geophysics.ou.edu/solid_earth/notes/mag_earth/magnetic_field_a.gif
And trhe lines were lower in America.

As I explained to Just The Facts November 10, 2011 at 9:20 pm
why the difference in the locations that you’ve cited versus those in the sources above?
“Because the concept of the ‘magnetic pole’ is a bit complicated. If you are walking on the ground with a compass or a device measuring the dip of the needle you might find a point where the horizontal force is zero and the magnetic field is vertical, so that is one definition of the ‘magnetic pole’ [and the one your sources show. But that is not the pole the particles that create the aurorae see. That is called the ‘corrected geomagnetic pole’. The reason for the difference is that the small-scale magnetic sources that control the field on the ground disappear or weaken with height, so that out in the magnetosphere the field is simpler and different.”
You can see this for yourself: http://www.swpc.noaa.gov/pmap/pmapN.html The center of the oval is not at the ‘magnetic pole’ or where the lines you show for the surface field. Rather it is found in Northern Greenland. Here you can calculate the corrected geomagnetic latitude of any point: http://omniweb.gsfc.nasa.gov/vitmo/cgm_vitmo.html also the location of the pole: mark these parameters: North CGM Pole Latitude for surface of the Earth & North CGM Pole Longitude for surface of the Earth.
If you do, you’ll find that the pole changes very slowly 1990 (79.07N 279.98E), 1900 (81.04N 278.09E). Here is a globe view: http://www.leif.org/research/Mag-Poles-1900-1990.png . The pins show the positions, the pink arrows the distances to Europe and New England, and the cyan arrows to Iceland and the Faroe Islands.
And the lines were lower in America.
The lines have little to do with where the aurorae are http://www.swpc.noaa.gov/pmap/AnimateN.html
The aurorae ‘see’ a pole in Northern Greenland because that is where the field lines go out into the middle of the magnetospheric tail tens of thousands km out where the particles that generate the aurorae come from.
There comes a times when it is time to cut your losses. Now is that time for you. For your own sake.

November 19, 2011 7:02 pm

If you do, you’ll find that the pole position changes very slowly 1800 (78.60N 286.49E), 1900 (79.07N 279.98E), 1990 (81.04N 278.09E).

You find something using inappropriate data splicing disparate datasets as we have seen. The German data shows how wrong you are [1946-1949 vs. 1951-1954]. Inappropriate [and cherry picked] data and ignorance about auroral physics is a fatal combination.

November 19, 2011 8:39 pm

Leif,
are you done in saying no senses and continuously twisting my research?
The historical record of mid-lat aurora, that I have studied, say what I found.
The other records from north America and north Europe, that we have, say the same thing (that is, they show a 60-year cycle) in a complementary way that you do not grasp.
As the author of my paper I say that you have not understood it. Moreover, in my opinion you have no deep understanding on these topics in general.
Your behavior proves only the deep personal ostility that you have agaist my research.
The scientific community will found out in the future whether I am right or wrong, do not worry.

As the author of my paper I say that you have not understood it.
There are, indeed, things in the paper that I cannot understand. I have asked for clarification and explanation, but you have evaded such, so your paper stays obscure on these points. I’ll try again to see if you offer explanation:
“Start with that statement of yours. ‘magnetosphere gets stronger’. What is that? Which magnetosphere? How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
Your behavior proves only the deep personal hostility that you have agaist my research.
I shall criticize any paper that is as poor as yours. Nothing personal, just business.

November 20, 2011 5:04 am

Leif,
you have proved nothing.
You just proved that you have not understood the paper, nor the results, nor the data.
Your argument is simply based on a rejection of the data because you do not grasp the complex dynamics that they show, which is a quite naive argument in physics. I explained the reasons of this complex dynamics in the paper and here, but you did not get it.
Sorry, Leif.

Your ‘explanation’ is beyond understanding. You still evade this:

How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
which seems to be at the root of your ‘explanation’.

November 20, 2011 9:12 am

Leif,
the paper contains sufficient qualitative information and several conjectures on the topic that you are not grasping. A detailed mathematical explanation of the phenomenon is not presented in the current paper and may be the topic of another paper. In the current paper I show the existence of the phenomenon and I argue that even if we do not understand in full the microphysics of it yet, we can adopt the same logic of Kelvin for solving the tides to reconstruct and forecast climate oscillations.
Research frontier is different from just reading a school textbook where everything looks clear, dear Leif. In research frontier the things move slower. One step by time.
So, be patient, try to have an open mind and stop thinking that everytime the data do not fit the naive theories written in your old dusty textbooks, the data must be wrong. Who knows, perhaps you too may discover something interesting a day.

I’m not grasping those because their foundation is not correct and conflicts with known physics of the aurorae. You are evading explaining yourself because you know[?] that your foundation is wrong. So, once again:
You say “magnetosphere gets stronger”.
How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
There are many more steps to go through, but we go slow and take them one at a time. So, please take this first one. If you do not, IMHO, you have forfeited further consideration.

Darned shame to find Lief & Nicola at each other’s throats. Seems to me that they both are telling us that the sun has a significant effect on global climate.
I guess the devil is in the details!

November 20, 2011 10:47 am

Leif, sorry you do not understand the issue. As I have explained you many times this is frontier research. I am not trying to explain you something that you can read in your textbooks.
What I say in the paper is supported by the data I analyze and by my numerous cross verifications. Get it and move on.
You claim that the data are wrong because they do not fit your understanding: you are free to keep such position if you like.
I say the data are correct and show an interesting dynamical phenomenon not yet fully understood that can indirectly also explain climate change, as I explain in the paper.
Does my paper explain every related physical issue? No, it does not yet. It is frontier research, not a high school science project. And many mysteries remain.
I need to say that in the past, people like you have always opposed any scientific advancement by using as argument that not everything was explained yet and unexplained things remained.
For example, when Kepler argued that the orbital data were showing that the orbits of the planets were elliptical, people like you opposed him claiming that the data were wrong because the theory claimed the orbits had to be circular. When Newton proposed his force of gravity to explain Kepler’s findings people like you opposed Newton claiming that his force was only a product of his imagination. When Einstein proposed his theory, he was derided and Nazi German collected one hundred scientists thinking like you to disprove him. And there are thousands of other examples like that in the history of science.
As I said before, be patient, try to have an open mind and stop thinking that every time the data do not fit the naive theories written in your old dusty textbooks, the data must be wrong.
If you want to think and act in a different way, you are free to do that and keep your prejudices. But in my understanding such a behavior proves only that you have a very narrow understanding of what constitutes science and of how science really progresses.

Yes, if you get the details wrong or they conflict with known physics [What Nicola calls ‘old dusty textbooks’] the whole thing is just hand-waving. Now, I’ll grant that ‘hand waves’ are the waves most commonly seen.
And don’t think I’m at Nicola’s throat. On the contrary I’m patiently and carefully examining his claims and trying to educate him a bit about what is known and how not to mal-treat data just because they seen to support muddled ideas. I have tried to make Nicola explain those ideas, but so far in vain. [prediction: it will continue to be in vain]. You may consider my comments here as a thorough peer-review.

You treat the [cherry picked] data inappropriately on false premises. My understanding is what is known from all experience up to now, not just my understanding.
Does my paper explain every related physical issue?
It does not explain any issue.
And now you are comparing yourself with Kepler and Einstein…

I thought that your paper will benefit from scrutiny, but evidently you are concerned that too much light will be shone on it and exposing its flaws.

Much more frequent than Nicola Scafetta, way ahead of aurora or any form of it, or climate, and forget about anything with ‘magnetic’.

That you don’t respond is proof enough that you have no clue. Now, it is OK to admit this, either explicitly [which is the honorable thing to do] or implicitly by being non-responsive.
Read the paper with open mind.
I always do. And I find it wanting.

November 20, 2011 3:39 pm

The html didn’t work. But the link does. I didn’t mean to interrupt you, gentlemen, unless it would be helpful to point out that this thread of comments seems to have become a battle between scientists with differing conclusions about what to do with data that most would start any article by mentioning that the relationship between aurorae, geomagnetism, and solar activity isn’t even understood well enough to be an emerging science. Legitimate – no question. Any scientific pursuit it legitimate. Neither of you two have any reason to be accusing (even politely) of the other because there just isn’t enough consensus yet on how best to use the data we have. And there is so much more to discern. Like the aurora borealis, appearing without warning whether we predict it or not, the ‘aha’ moment when (if) this disagreement leads to truth and understanding is something to look forward to with great anticipation. Instead I see contentiousness, accusation, attempted mutual censorship (thinly veiled).
Meanwhile, having read through as much of this as I can grasp (I am not a scientist, but I was born asking ‘why’ before I even knew how to form the word)…I haven’t found any clues to my personal quest. Sometime between 1972 and 1974 (my best estimation) I witness an aurora borealis display unlike any described here. There are no photos on the web even resembling what I saw. I was on the northern verge of Lake Michigan, with absolutely no city lights to muddle the display. At first the northen third of the sky took on a sheen with a little color to it, then it began to coalesce into a greenish veil. But by 10 pm or so, it was as if dozens of jets had flown over and left their trails in the sky, and then they started swirling, moving to and fro, mixing together in no pattern I (a teenager at the time) could discern. The display spread to the highest point in the sky and then began to fill the southern sky.
My web searching turned up one blog where someone mentioned seeing something like this on the Keewenaw Peninsula in 1972. But that’s not all, and I guess night photography just wasn’t sophisticated enough to capture it and still be in good condition now, so many decades later. My experience happened during the week of July 4. Then, the following year and one week later, we returned (who could resist?) and – you guessed it – it happened again. I don’t remember if that display had the uncharacteristic swirling going on. But back to your data here. I did look through your solar flare information from the early 60’s, and noticed that there were a number of instances where an important flare event occurred in July or October one year, and in both months, happened again one week later the following year.
So that’s my contribution to the discussion, and it looks like it would be more useful to Dr. Scafetta, if anyone, to observe that in addition to the 60 yr and 11 yr cycles and other possible patterns we are looking for here, there are actually quite a few instances where auroras, the the solar flares that seem to be connected with them, appear 2 years in a sequence, but the later event is often roughly a week to 10 days later. I’m getting this from your review of the aurorae and their corresponding Kp index (indices?). So, thank you for the information. And may I encourage both of you to find a constructive use for all the mental energy being expended here. I for one, at least got that much out of it. Anyone else?

November 20, 2011 4:06 pm

Leif,
how many times I need to tell you that my paper was not supposed to address in details any possible issues? This is frontier research, not a textbook well established theory explanation.
It was not the purpose of the paper to address the issue you are questioning in detailed physical terms and in a rigorous physical mathematical explanation. This is “work in progress”. In the paper I show the existence of the phenomenon.
So, be patient, try to have an open mind and stop thinking that everytime the data do not fit the naive theories written in your old dusty textbooks, the data must be wrong.
You are missing the point of my paper. Moreover, you always miss the point of scientific research in general which does not require that every issue be solved at the same time.
Claiming that a paper is wrong just because it highligths also issues not yet fully understood proves only that you do not understand scientific progress and research.

how many times I need to tell you that my paper was not supposed to address in details any possible issues?
And how many times do I need to tell you that it is legitimate to ask for clarification of what you wrote. It is simply courteously to respond So again:
You say “magnetosphere gets stronger”.
How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
This is a key point of your paper:
“In this paper, we postulate that the annual frequency occurrence of mid-latitude aurora events is a measure of the level of electrification of the global ionosphere, which is mostly regulated by incoming cosmic ray flux variations. When the Earth’s magnetosphere is weaker relative to the surrounding space environment the ionosphere can be highly ionized by cosmic rays, and large auroras would more likely form at the mid-latitudes. This phenomenon would occur because when the upper atmosphere is highly ionized, it would also be electrically quite sensitive to large solar wind particle fluxes and favor the formation of extended mid-latitude auroras. In fact, higher ionization of the atmosphere would mostly occur when the magnetosphere is weaker and cosmic ray as well as solar wind particles can more easily reach the mid-latitudes. Then, the level of atmospheric ionization and of the global electric circuit of the atmosphere should regulate the cloud system. If the above theory is correct, the frequencies of the mid-latitude aurora records should be present in the climate records too.”
So: ‘When the Earth’s magnetosphere is weaker relative to the surrounding space environment ‘ means what? what is its strength? measured and defined how?
You say “if the above theory is correct…”. It starts with making a claim about something being weaker. If you cannot explain what you mean, then you have no theory, and then the whole paper is moot. BTW, the rest of the theory is already wrong. Things don’t work anywhere near what you postulate [according to the old dusty textbooks and to all measurements and modern theories]. But we will come to that, once you clarify the foundation of your ‘theory’.

November 20, 2011 4:42 pm

This is a key point of your paper:
“In this paper, we postulate that the annual frequency occurrence of mid-latitude aurora events is a measure of the level of electrification of the global ionosphere, which is mostly regulated by incoming cosmic ray flux variations”
This is already completely wrong. Cosmic rays have nothing to do with this. The ionosphere is created by ultraviolet radiation from the sun helped along by particles precipitating from far out in the magnetosphere.
You can learn more here: http://en.wikipedia.org/wiki/Ionosphere
“The ionosphere is a part of the upper atmosphere, comprising portions of the mesosphere, thermosphere and exosphere, distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. ”
So when you say “If the above theory is correct, the frequencies of the mid-latitude aurora records should be present in the climate records too.” you are already in trouble, as the ‘above theory’ is not correct.

November 20, 2011 5:44 pm

Leif,
do you want to stop to insist on this tred.
As author of my paper I say that you have not understood it. Moreover, your comments have been severely inappropriate in many ways.
In my opinion you just want to mislead and disrupt the readers of this blog with your sophistic auguments and not let them to understand nor address the real issues covered in my paper. You need to understand that after a while you get very boring, and many readers of this blog have realized it.
I can say that my paper has been reviwed by two persons plus the editor. One referee, for what I can understand from his/her detailed comments, is quite familiar with auroras data and the other referee is extremely expert in sun/athmospheric interactions. Both persons have written detailed comments and seem to me far more expert than you on the topics addressed in my paper.
If you think that my paper contains fatal errors you are very welcome to write an appropriate scientific comment and submit it to the journal. And I will respond to it in the appropriate way.
However, that you take advantage of the extreme tollerance of Antony Watts in allowing any kind of comments on this blog for continuously jumping and jelling around your personal opinion on everything disrupting it in many ways with your numerous nosenses, is another thing.
In a regular scientific conference people like you are put out the door after two minutes.
As Harkness Lives has said above, your presence in this blog surpasses by far the same topic of the paper that herein was supposed to be addressed.
So, be more educated and do not disrupt a discussion and a topic that you evidently have no interest in undestanding in the appropriate scientific terms nor in the terms addressed by the author.
Again, if you think that my paper contains fatal errors you are very welcome to write an appropriate scientific comment and submit it to the journal. And I will respond to it in the appropriate way.

You can respond here in an appropriate way. It would be quite ridiculous to write a rebuttal of the above quote [and all the other wrong ones] as it is so obviously wrong, not to speak about the unneeded embarrassment you would suffer.
I take your inability to answer my question ‘When the Earth’s magnetosphere is weaker relative to the surrounding space environment ‘ means what? what is its strength? measured and defined how? as an admission of your claim being rubbish.
In a regular scientific conference people like you are put out the door after two minutes.

Another important question: Do you really believe this: “the global ionosphere, which is mostly regulated by incoming cosmic ray flux variations” and what is that belief based on? in view of http://en.wikipedia.org/wiki/Ionosphere “The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of about 50 km to more than 1000 km. It owes its existence primarily to ultraviolet radiation from the Sun.” No cosmic rays here.
So, do you stand by your statement which is a cornerstone of your ‘theory’?

“”In a regular scientific conference people like you are put out the door after two minutes.”

Dear Leif, in the scientific conferences you keep an educated and respectful attitude for what I have noted. That is why nobody has put you out one of them yet.
For example, at the last SORCE meeting in September we were even seated very close to each other and I did not note any inappropriate behavior from your side. At my presentation, for example, you kept a religious silence: before, during and after it. You did not start jumping around, disrupt the presentations, stealing the microphone and pretending to say your opinion on every issue and comment, arguing against everybody etc..
However, I believe that your behavior in this blog is inappropriate and offensive to those readers who want to know more about these complex issues. And they would like to undersand mostly my views on the issue given that the topic addressed here is about one of my papers.

If you do not like my style of writing it is your personal opinion: i do not know what to say.
Moreover, I have received emails from scientists quite famous and expert on auroras and the electric circuit on the atmosphere who wanted to share their appreciation for the content of the paper, who they have read with open mind. And I have also received several emails from people that have read this blog who are professional physicists and geophysicists who do not understand your unreasonable behavior.

However, I believe that your behavior in this blog is inappropriate and offensive to those readers who want to know more about these complex issues. And they would like to understand mostly my views on the issue given that the topic addressed here is about one of my papers.
They could have asked your questions and engaged in discussion with you. Not many, if any, did.
I seem to be the only one that have asked you specific questions, which you have evaded.
And I have also received several emails from people that have read this blog who are professional physicists and geophysicists who do not understand your unreasonable behavior.
They clearly did not have the guts to say it here. Therefore do not count in my book.
I do not know what else to say to you.
You can start by answering my questions:
Another important question: Do you really believe this: “the global ionosphere, which is mostly regulated by incoming cosmic ray flux variations” and what is that belief based on?
So: ‘When the Earth’s magnetosphere is weaker relative to the surrounding space environment ‘ means what? what is its strength? measured and defined how?
This is what a reasonable and honorable person would do.

3. Mid latitude aurora appear at low Kp only when a geomagnetic storm is experienced the previous day. FALSE.
4. Mid latitude aurora follow the sunspot number. FALSE.

Your assessment of my credibility is of no concern. The correct way of dealing with a list of incorrect claims is to dispose with them one at a time and get your acknowledgement that you were wrong on that particular one, then mode on the next, etc. Let us start with the most blatant error, namely your claim that the mid-latitude aurorae does not follow the solar cycle. The Figure in Schroeder’s paper shows that it does. Here is a refutation of that erroneous claim: http://www.leif.org/research/Mid-Latitude-Aurorae-Solar-Cycle.png

Here is a refutation of that erroneous claim:
As posted previously two graphs from the Silverman paper that clearly show a divergence of sunspot number and mid latitude aurora. The main point you are still not seeing is the modulation of the aurorae, notice the aurora records do not return to zero during cycle min, also notice the roughly 30 year upswing then 30 year downswing in both graphs. Aurorae will be more prevalent at cycle max but they do not follow the sunspot cycle verbatim (the New England data diverges greatly from the sunspot data, an overlay would show this very clearly), there is modulation on the minimum as even your manipulated cherry picked Shroder/Silverman graph also shows… This is one of the modulations Nicola is referring to.

The Silverman paper is interesting and backs up the Scafetta paper. Importantly it is necessary to only look at the data covering mid-latitudes. Two graphs in particular covering from 1700-1948 which cover the New England data (20,000 records taken over several hundred locations 41-45N) and the Fritz data that appears to be >55N show a clear 60 year period (the Dalton minimum has to be allowed for). The graphs agree with fig 2B in Scafetta’s paper.
Clearly the mid-latitude aurora record mentioned does NOT follow the sunspot or aa record of the era (with the exception of the Dalton).

Reliable data shows that the mid-latitude aurora follows the sunspot number as shown here [lower right]. Scafetta’s curve [red] does not match the auroral record after 1850 [not to speak about before 1700] when we have good climate data.

The SIlverman New England data 1800-1948 consists of 20,000 records from several hundred stations. Multiple records on one day are treated as one.
—————–
Data for New England were taken from a compilation by
S. M. Silverman based on several sources (for a descriptio
of observational systems from the end of the eighteenth cen
tury to 1870, see Fleming [1990]). The primary source used
here was the meteorological registers kept by voluntary ob-
servers in the network established by the Smithsonian Insti-
tution and continued, primarily, by the Army Signal Servic
and the Weather Bureau. Observations were also publishe
in the Monthly Weather Review and in the series, Climato
logical Data of the United States. Some additional data for
individual locations were also used, as, for example, the
observations of Bentley in Jericho, Vermont, from 1881 to
1931 [Silverman and Blanchard, 1983]. Some data were also
taken from the auroral catalogs published by Lovering [ 1866
1871] and Fritz [1873]. The New England data base com-
prised about 20,000 records, from 1741 to 1948. Some scat
tered records prior to 1741 exist but are not utilized here
Altogether several hundred locations are involved. Their geo
graphic coordinates range from about 41 ø to 45 ø , and the
corresponding corrected geomagnetic coordinates from abou
53 ø to 57 ø .
————————
A pretty comprehensive data set I would have thought. That you choose to go with a single observer over a shorter time frame is your prerogative, but hardly a convincing argument.
When the Silverman aurora data is overlaid over the SIDC data the disconnect becomes clearly apparent.

The SIlverman New England data 1800-1948 consists of 20,000 records from several hundred stations.
That is part of the problem. A record from a single observer that observed on every clear day is much to be preferred. This illustrates the problem: http:/www.leif.org/research/Numbers-of-Observers-Influence.png Assume a cycle of constant amplitude [blue curve], but let the number of random observers change with time [or their conditions, e.g increasing city lights] [green curve] then the number of reports [even if multiple are treated as one] will be the product of the two curves [the pink curve], so the envelope is more a reflection of the number of observers. Note how the bottom values follow the same curve and do not go to zero]. This is the problem with the raw data.
When the Silverman aurora data is overlaid over the SIDC data the disconnect becomes clearly apparent.
Yes, it clearly shows the problems with the Silverman data. If you overlay the Faroes data, their disconnect with both Silverman and SIDC becomes even more apparent [yet are an eye-catcher on Scafetta’s Figure 2B, and a major claim for the 60-year period – how well they follolw the red sine curve]. To sum up: collections [no matter of how many] of random observers will always have these problems. There are two remedies: (1) use only a few long-running observers that make observations on a regular schedule, and (2) since we know that the number of mid-latitude aurorae goes to almost zero at solar minimum, we can take that into account and calibrate the counts so that this is fulfilled.
Here you can see how severe the problem is for the Faroe data: http://www.leif.org/research/Faroe-Aurorae-in-Context.png.
As shown in the yellow rectangle the Faroe Islands are about halfway between Iceland and Denmark and Germany. The two records on the left [Vestmannoe and Berufjord] are from Iceland and agree that the aurorae were rare around 1910. The record from Denmark shows also a paucity of aurorae at that time. Yet the Faroes have a strong maximum from 1890 to 1920 showing that the Faroe Island records [used by Scafetta] do not show the true [low] occurrence. The reason likely explained by the effect illustrated by my graph above.
We have a very good, quantitative theory for the aurorae worked out decades ago and confirmed by modern measurements every day. Mid-latitude aurorae follow the sunspot cycle closely [not ‘verbatim’ as you said, because nature is a noisy place] and are clearly present in the geomagnetic record as well. That aurorae tend to occur at the time when sunspot groups pass near the central meridian of the Sun was already noted by Mairan in 1733. It was shown by Carrington, Spoerer and Wolf that the auroral frequency followed the sunspot cycle [‘old, dusty text book’ knowledge] and everything we have observed since with modern, controlled data confirms that. There is no other choice to be had. Aurorae do not behave differently in the past as they do now. The same physics is at work.

You are still not seeing the main point of the divergence between the aurora and sunspot record.
Even if we use your preferred data or accept your point about more observers there is still a 60 year movement in the aurora recorded at solar minimum (that does return to around zero every 60 or so years), this 60 year trend is also observed in the aurora peaks that can go against the trend in the sunspot record. This trend cant be explained away as you have tried to do. Dont try to line up each hump in the aurora/sunspot record, look at the max/min trends in both records.
Basically the mid latitude aurora record has a quasi 60 year trend and does not follow the same trend as the sunspot record.

When the Silverman aurora data is overlaid over the SIDC data
The Ap geomagnetic index is a measure of currents in the mid-latitude ionosphere and generally correlates well with auroral activity. Only the strongest outbreak of currents such as generally found at high solar activity give rise to visible aurorae at mid-latitudes. The high-speed streams often occurring on the declining branch of the cycle are generally not associated with sporadic CME [giving us mid-latitude aurorae], but do increase the Ap-index [at times substantially]. So a combination of SSN and Ap should be a good measure of mid-latitude auroral frequency. I have overlain the Ap-record on your SSN and Silverman overlay: http://www.leif.org/research/SSN-Ap-Aurorae.png
Several things are visible: the effect of number of observers, the occasional impact of high-speed streams, the low activity during the first few cycles of the 20th century. This is in contrast to Scafetta’s Figure 2B on which his claim is built: http://www.leif.org/research/Sharp-Overlay-Faroes-Aurora.png
Scafetta’s sleight of hand slipping the Faroes data was one of my first criticisms and still stands.

Basically the mid latitude aurora record has a quasi 60 year trend and does not follow the same trend as the sunspot record.
As both the sunspot number and the Ap-index [and perhaps best their combination] are the controlling factors of the auroral record, it is of interest to compute the power spectrum of both:
http://www.leif.org/research/FFT-SSN-Ap-1844-2011.png after all, Scafetta claims he is comparing frequencies.
As you can see for periods above 5 years the two power spectra agree, and there is no hint of any 60-yr period. The interval 1844-2011 for which I have geomagnetic data matches well the 1850-2010 span of climate data, that is used in Scafetta’s paper, so it is very appropriate to compare datasets for that interval.
It is well-known that there is ~90-year period in both SSN [the Gleisberg cycle] and auroral data, but no 60-yr. E.g. http://www.leif.org/EOS/JA089iA05p03023.pdf “Eighty-Eight Year Periodicity in Solar-Terrestrial Phenomena Confirmed [Joan Feyman & Paul Fougere].

That is not a reasonable statement and implies that the number of observers must fluctuate on a 60 year period, even if your theory is right which I am not nearly convinced, the observers would merely be amplifying a trend that is already there. The Ap record is also now showing a similar trend that agrees with the mid latitude aurora record, does it also suffer from over counting?

No, as http://www.leif.org/research/Numbers-of-Observers-Influence.png shows varying the number of observers CREATES the trend. The blue curve is a cycle with no trend.
The Ap record is also now showing a similar trend that agrees with the mid latitude aurora record, does it also suffer from over counting?
The real issue is that Ap is a measure of the currents. At sunspot maximum we get more of the flares that push the aurorae down to mid-latitudes, so a combination of Ap and SSN is really the best if one wants to go past 1st order. The point is that neither Ap nor SSN shows any 60-yr period over the time of the climate record considered by Scafetta:
http://www.leif.org/research/FFT-SSN-Ap-1844-2011.png
I am also wary of the Faroes data and wonder if it was necessary to include in the paper.
That data is vital for the paper, see Figure 2B.
“BTW, Scafetta’s 60-yr period ‘predicts’ high solar activity the next 30 years.”
You might need to expand on that one?

Figure 2B: when the red curve has minima, the number of aurorae [i.e. solar activity] is highest. The next minimum is about 2030, so that is when there should be most aurorae and solar activity. Compare with 1850s, 1780s, 1730s. Similarly, solar activity should have been large in the 1910s [the blue Faroe curve is picked to ‘prove’ that].

So much for “A shared frequency set between mid-latitude aurora and global temperature”
The 11-yr solar cycle peak is clearly in the data as we would expect from the TSI variation. The clear peak at exactly one year is due to the fact that the data is an anomaly over an average yearly curve, and there is variation in the yearly curve from year to year.

The SSN record is not important as it diverges from the aurora record. The Ap record needs to be looked at.
That data is vital for the paper, see Figure 2B.
Disagree, I think you need to give a bit of slack here. Nicola has identified a quasi 60 year trend in the mid latitude aurora data. A similar trend is also produced in his Jupiter/Saturn tidal elongations. He has only speculated on the physical link but if correct some of the inner planets may also add and take away from the strict 60 year cycle.
Figure 2B: when the red curve has minima, the number of aurorae [i.e. solar activity] is highest. The next minimum is about 2030, so that is when there should be most aurorae and solar activity. Compare with 1850s, 1780s, 1730s. Similarly, solar activity should have been large in the 1910s
No, still missing the point. The red curve is the influence on the magnetosphere, not necessarily solar output, in my opinion this is the important factor. The Dalton minimum is a good example of this which should be repeated again in the next 30 years. According to the theory the magnetosphere is shaped by planetary influence which is then subject to the solar output of the day. Grand minima obviously will over ride the red curve.

Leif continues with his misinformation and twisting of data and facts.
>BTW, Scafetta’s 60-yr period ‘predicts’ high solar activity the next 30 years.
No, my model predicts a low solar activity the next 30 years.
Leif also continues to mix the American New England auroras to the mid-latitude auroras from Europe as if they correspond to the same angle relative to the north magnetic pole.
Leif does not understand that New England is located far norther than central Europe relative to the magnetic north pole.
For example between 1800 and 1950 the north magnetic pole was located on average at about
latitude 72N ; longitude -99
New England is located at about
latitude 42N ; longitude -73
Germany is located at
latitude 51N ; longitude 10
It is evident from the above that, like Iceland, New England was (and is) far closer to the north magnetic pole than Germany. This is why the 60-year modulation in the two records is negative-correlated: when one increases the other decreases. Try to calculate the angle, Leif!

“BTW, Scafetta’s 60-yr period ‘predicts’ high solar activity the next 30 years.”
No, my model predicts a low solar activity the next 30 years.

In Figure 2B you claim that auroral frequency is largest during the minima of the red sine curve. High auroral frequency is a sign of high solar activity. So since your red curve has a minimum in 2030, that predicts high auroral frequency i.e. high solar activity.
New England is located far norther than central Europe relative to the magnetic north pole.
The northern geomagnetic pole is not at “latitude 72N ; longitude -99”, but at 79N, 80W. [ http://omniweb.gsfc.nasa.gov/vitmo/cgm_vitmo.html ]. I showed you the locations already here: http://www.leif.org/research/Mag-Poles-1900-1990.png [also the pole in 1800]. Check the angles [pink arrows] they are the same Your mistake is to believe that the pole on the ground is the pole seen by the aurora and solar wind. That pole is in Northern Greenland at 79N, 80W. You can see that directly here: http://www.swpc.noaa.gov/pmap/

The magnetosphere reacts directly to solar output of flares, CMEs, and other stuff that creates mid-latitude aurorae.

Here is a bit of education for you: http://www.leif.org/EOS/96EO00237_rga.pdf
“Geomagnetic coordinates are applied universally to organize many types of geophysical data, particularly those for solar-terrestrial and magnetospheric scientists.”
“For the many scientists not working in geomagnetism and for ordinary citizens, the present magnetic pole marking only leads to a confusion as to what is being located at the given positions. The major global cartographers need to become aware of the modern science of geomagnetism and either improve the accuracy of their maps or remove their dubious “Magnetic Pole” locations altogether.” This goes for you as well.

November 23, 2011 11:06 am

Sorry, Leif. You are confusing the topic and still not understending the issue. As I said the next 30 year predicts a low solar activity, low magnetic field shielding that yields more low latitude auroras.
You do not have to think only at he sun, but at the dynamics of the magnetosphere.
Moreover, the location of the North Magnetic pole is here

latitude 72N ; longitude 99W.
Now it is about 82.7° N 114.4° W
the angle between the north magnetic pole and New England was about 32 degree, the angle between North Magnetic pole and Germany was about 48 degree
The angle between north magnetic pole and Iceland was about 29 degree, so it was close to New England

As I said the next 30 year predicts a low solar activity, low magnetic field shielding that yields more low latitude auroras.
So you are saying that more low [perhaps you mean mid-] latitude aurorae occur at low solar activity. This places you on the fringe. All data up to now associates high mid-latitude aurorae frequency with high solar activity [Figure 3 of Silverman shows the very low frequency during the Maunder, Dalton, and 1910 solar activity periods]. I think you have now disqualified your theory permanently and ruined your reputation forever.
You do not have to think only at he sun, but at the dynamics of the magnetosphere.
Which brings me back to my question:
How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?
Which you have evaded, but now must answer.
Moreover, the location of the North Magnetic pole is here
http://academic.greensboroday.org/~regesterj/potl/E&M/Magnetism/popup.north.pole1.gif

You did not take the trouble to study http://www.leif.org/EOS/96EO00237_rga.pdf
“Geomagnetic coordinates are applied universally to organize many types of geophysical data, particularly those for solar-terrestrial and magnetospheric scientists.”
“For the many scientists not working in geomagnetism and for ordinary citizens, the present magnetic pole marking only leads to a confusion as to what is being located at the given positions. The major global cartographers need to become aware of the modern science of geomagnetism and either improve the accuracy of their maps or remove their dubious “Magnetic Pole” locations altogether.”
The ‘magnetic pole’ you show is not the location that organizes the magnetosphere. I could give you many references for this, but since you don’t even read the ones I have given, I think you won’t take the trouble to educate yourself. It is universally recognized that auroral frequency follow lines of corrected geomagnetic latitude [google ‘aurora corrected latitude’ to see more than a million references]

In fact, all north United States are covered by the aurora oval, while most mid-latitude Europe and Asia regions (from Germany to Italy up to Japan) are not.
Moreover, if you look carefully the region around England up to the Faroes, region is colored with a dark blue, while the American New England region is colored almost in white. This means that region around England up to the Faroes behaves more like the Mid-latite aurora fron Europe and Asia.
Finally, note that 100 years ago the aurora oval was even more skewed toward New England and North United States because the north magnetic pole was even closer to central Canada by 10 degree and the patterns were likely clearer in my favor.

It is also flares, CMEs, magnetic field, TSI, mid-latitude aurorae, etc, all of which follow the sunspot number. But regardless of that, your own plot http://www.leif.org/research/High-Low-Switch.png shows how the red curve follow the sunspot number and the number of aurora between 1700 and 1900, but that relationship breaks down thereafter. Is this what you are trying to say? That although before 1900 you would claim that there was some correlation, that is no longer the case.
2) the mid-latitude region in Europe ans Asia (the arc from Germany to Italy to Japan) is out your aurora oval as I said.
Does not make sense, Italy is way to far south. There are VERY few aurorae reported from Italy. The vast majority comes from Germany, England, and France. And all of these are outside of the oval [including the US], anyway. The blue area is not auroral emission, but just quiet background.

Italy and Japan are on the same isochasm [line of equal auroral frequency] as Florida and Cuba, so are not mid-latitude in the auroral sense. E.g. http://www.leif.org/EOS/JZ065i007p01967.pdf
Vestine has constructed isochasm maps that show this very clearly, also how the aurorae matches geomagnetic disturbances: http://www.leif.org/EOS/TE049i002p00077.pdf

Note Italy having a frequency 10-50 times less than Germany and New England. The counts from Italy and Japan make no dent in the total.

Thanks Nicola, one paragraph in particular gives more insight into why you chose the Faroe data set.
“Where the 60-year cycle in the Faroes is negative correlated to the 60 year cycle in the temperature while the 60-year cycle in Iceland is positive correlated to the 60 year cycle in the temperature from 1880 to 1940. The same complementary dynamics exists between the mid-latitude European/Asian auroras (which are explicitly studied in my paper) and the American New England auroras (which occupy a northern region relative to the magnetic north pole despite their geographical latitude) for the 1800-1900 period.”

At higher solar activity the oval expands in all directions and the emission moves south to cover the blue background. The ‘weaker’ magnetosphere is nonsense.

Progress in science happens when complexity is conquered and the essentials extracted and expressed in simple ways. The complexity in auroral, magnetospheric, and solar physics is vast, but we have managed to unravel the simpler physics underlying it all. Speculation is always interesting, but when it leaves the terra firma of valid analysis and solid science it can become counter-productive.

Nicola has outlined why the New England data should not be associated with the European data which I now see I did incorrectly. Your referenced links also support his reasoning that show the two areas are subject to different strengths of the auroral oval. It would be beneficial if auroral data from Europe at a latitude less than 55 deg was available after 1900 to ensure a reliable record. In the absence of such data Nicola has substituted the Faroe data from 62 deg because remarkably it has the same frequency signal compared to the European data prior to 1900. This may not be ideal but it explains the process. I note in Shroders paper that has a limited data range from 1946 to 1964 from Germany that the auroral data does not follow the sunspot record as you may expect. Cycle max of SC18 displays a max reading per year of 41 while the highest sunspot cycle in our history SC19 only recorded 29 aurorae. There is sufficient data including the 23% of aurorae that occur at a Kp value of 4 or less that demonstrate mid latitude aurorae of Europe are not solely dependent on solar output.
At higher solar activity the oval expands in all directions and the emission moves south to cover the blue background. The ‘weaker’ magnetosphere is nonsense. I have asked Nicola to explain what he means by that, but he evades/refuses/has no clue/whatever to provide an answer. Perhaps you could provide one?
So your referenced diagrams support Nicola’s logic.
Nicola does not provide a mechanism for a weaker/stronger magnetosphere, but my understanding is the interaction from planetary bodies on our magnetosphere is one proposal.

On the contrary, the two areas have the same distance from the Corrected Geomagnetic Pole: http://www.leif.org/research/Mag-Poles-1900-1990.png
and the same dependency on magnetospheric conditions (measured by the Kp needed for an overhead aurorae, the area between the yellow and red lines):
http://www.swpc.noaa.gov/Aurora/globeNE.html
http://www.swpc.noaa.gov/Aurora/globeNW.html
It would be beneficial if auroral data from Europe at a latitude less than 55 deg was available after 1900 to ensure a reliable record.
The Danish record is good for this. There is nothing magical about the latitude of 55N [and part of Denmark is south of 55N).
In the absence of such data Nicola has substituted the Faroe data from 62 deg because remarkably it has the same frequency signal compared to the European data prior to 1900.
That is just cherry picking of bad data. The Faroe Islands are halfway between Iceland and Denmark and must show data that is at least between those two areas [e.g. that activity was low from 1900 to 1920, but does not, so is no good: http://www.leif.org/research/Faroe-Aurorae-in-Context.png
Cycle max of SC18 displays a max reading per year of 41 while the highest sunspot cycle in our history SC19 only recorded 29 aurorae
There were 65 aurorae in SC18 and 90 in SC19. Breaking it down by single year does not enough statistical significance.
There is sufficient data including the 23% of aurorae that occur at a Kp value of 4 or less that demonstrate mid latitude aurorae of Europe are not solely dependent on solar output.
An aurora is a measure of magnetospheric output which is powered by the Sun. The distribution of Kp-values for Schroeder’s data http://www.leif.org/research/Kp-Distribution-Schroeder.png shows [each color a different column plus their sum] a broad plateau from Kp=5 to Kp=9 with a median of Kp=7 consistent with http://www.swpc.noaa.gov/Aurora/globeNE.html
The spread is just ordinary counting statistics. As a strong aurora extends ~500 km in height it will be visible more than 2000 km away [or ~20 degrees]. Even if we allow that it will only be noticed if at some altitude in the sky, 1000 km distance is reasonable, so a strong aurora in Norway may still be visible from Germany.
“At higher solar activity the oval expands in all directions and the emission moves south to cover the blue background. The ‘weaker’ magnetosphere is nonsense. I have asked Nicola to explain what he means by that, but he evades/refuses/has no clue/whatever to provide an answer. ”
So your referenced diagrams support Nicola’s logic.

No, as it expands in all directions and if the oval expands to New England it also expands to Germany and vice versa, so you will not get opposite occurrences.
Nicola does not provide a mechanism for a weaker/stronger magnetosphere, but my understanding is the interaction from planetary bodies on our magnetosphere is one proposal.
The notion of weaker/stronger magnetosphere is nonsense. Not even the Sun changes the ‘strength’ of the magnetosphere under any reasonable definition of ‘strength’. Nicola refuses to explain what he means with ‘strength’ so this notion is void until he does. The planetary influence on our magnetosphere would do what? The particles in the magnetosphere where the aurorae come from are transient and comes and goes on a time scale of hours. His discussion involving cosmic rays regulating the ionosphere is incoherent and wrong. The ionosphere is created and maintained by ultraviolet radiation from the Sun. Particles accelerated in the magnetotail can precipitate into the ionosphere and heat it, but that is all.

November 23, 2011 9:58 pm

There were 65 aurorae in SC18 and 90 in SC19. Breaking it down by single year does not enough statistical significance.
Miscounted. There were 79 in SC18 and 92 in SC19. The +/-counting error on random events is about the square root of the number of counts.

The blue dot is at a bit too high latitude. Most data came from Boston, not from Maine. And in any case the difference is so small that to talk about a reversal of behavior is nonsense and grasping for straws. A strong aurora is visible over an area several hundred kilometers across anyway so make your dots much larger. To have opposite behavior the locations must be of the order of a thousand km or more apart, because if not, south of the oval you would see an aurora in the north, but north of the oval [which itself is some hundreds km wide], you would see that same aurora to the south [thus the count will be the same]. So, there is no way one justify that the bahavior would be with different phases. Now, Nicola doesn’t know this [or pretends he doesn’t] as he measures from the wrong pole. But you know better now, right?

“This supplement presented contains corrections and new data about occurrences of north polar aurorae (<55 degrees). New data are based predominantly on the two Catalogues, i.e. of Loomis (LOO) and of Schroder (SC2). In the Catalogue LOO are collected the aurorae which were observed in North America. New data sources with their abbreviations are referenced.”
The data list is here:
ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/AURORAE/aurorae.dat.rev
and contains the total merged lists of 5381 entries of which 2372 are from North America.
Scafetta’s Figure 2B shows for 1850 about 136 aurorae. The list has indeed 136 entries and 87 of those are LOO, i.e. from North America.

Your text does not make sense. Did you just make it up? Following your procedure an aurora only seen in North America [perhaps it was cloudy in Europe] would not be counted. But it doesn’t matter as the ‘text’ is out of thin air.
However, it is worse than we thought:
I have plotted the data separately and compared with Scafetta’s plot:
http://www.leif.org/research/Krivsky-Pejml-Aurorae.png
You can see that Scafetta commits a deadly sin: adding the two records from North America [blue] and Europe+Asia [pink] over the whole of the interval 1700-1900. This is only allowed if both regions had data throughout, but the North America record only begins ~1776. The correct analysis would have to average the two series [gray stippled curve] and not adding them. Another example of invalid analysis.

Your performance here is embarrassing. The peer reviewers of Nicola’s paper are obviously in a different league to yourself. You have failed to be convincing on any single point.
I think you owe Nicola an apology…… if you are man enough?
“The authors adopted the occurrences of aurorae on the basis of the following
criteria: possible recurrence after roughly 27 days, roughly since 1792 (and
partly also before) auroral data were adopted provided there was guarantee
that they were simultaneously observed in a larger geographical region. i.e.
provided they were recorded at a number of stations in Region I or II (i.e.
Europe), or in Region I or II and at the same time in Region IV (i.e.
America). Fritz’s [2] division into regions is as follows: I – south of 46,
II – between 46 and 55 , III – from 55 to the polar circle, IV – America
south of 60 , V – high latitudes. If the source of an auroral observation
given by H. Fritz [2] was also given by another author, the latter has been
mentioned.

If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned.
This is quite different from what you said as the American data just being a backup [the backup idea just made up out of thin air]. And from the “Euro data still the catalyst”. The original list had 3878 entries. If the new data [2372 North America] were just changing a Fritz entry to an American entry, then the number of entries would not have changed. Yet the combined list has 5376 entries. Take the year 1850 for example. It has 136 entries of which 87 were American [LOO] and 46 were Fritz [with 3 more European]. So the combined data for that year was predominantly American and not European.
For the period of the Loomis [North American] data 1776-1872, there are 4175 entries in the combined list of which 2344 were from LOO and thus American and the rest, 1831, Euro+Asia. Soooo, as I said, the list for those crucial ~100 years were predominantly American, and in total the list was a good mixture of both regions. Thus, as I said, Scafetta is not correct in claiming [or is it you who is the originator of that claim: “Nicola had good reason not to use the New England data with the European data] that his data was European, because the North American were ‘different’. And it is still not correct to add the two series for the whole interval. So, there is still the deadly sin. Nothing has changed.
You still need that soap.

The peer reviewers of Nicola’s paper are obviously in a different league to yourself.
Yes, Indeed, they did not catch that elementary error Scafetta made nor his erroneous claim that the data were not American. That certainly places them rather low on the ladder, down there [as you say] in the different league. They did not do a good job and have led the public down.

So the combined data for that year was predominantly American and not European.
Read the explanation text again.
“The authors adopted the occurrences of aurorae on the basis of the following
criteria: possible recurrence after roughly 27 days, roughly since 1792 (and
partly also before) auroral data were adopted provided there was guarantee
that they were simultaneously observed in a larger geographical region. i.e.
provided they were recorded at a number of stations in Region I or II (i.e.
Europe), or in Region I or II and at the same time in Region IV (i.e.
America). Fritz’s [2] division into regions is as follows: I – south of 46,
II – between 46 and 55 , III – from 55 to the polar circle, IV – America
south of 60 , V – high latitudes. If the source of an auroral observation
given by H. Fritz [2] was also given by another author, the latter has been
mentioned.“
The authors are very clear, auroral data is not used unless it is “simultaneously observed in a larger geographical region.” There are no single records from America added to the list. The records are taken from multiple regions of Europe (Region l and ll) OR Europe (Region l and ll) AND at the same time Region lV (America). America is used as a backup reference or qualifier for Europe and thus is the latter record listed in the data. (there is only one label in the table)

Leif,
I think that Geoff may be right
The catalog I used is quite clear, no single American auroras are added to the list. An aurora is added to the list only if it satisfies one of the following condition:
1) it is observed in Region I AND Region II
2) it is observed in Region I AND Region IV
3) it is observed in Region II AND Region IV
where the regions are as following:
I – south of 46N (Europe and Asia),
II – between 46N and 55N (Europe and Asia)
IV – America south of 60N
It is evident that the American catalog cannot be simply added to the mid-latitude aurora record from Asia and Europe because at it is evident in this figure
http://www.landscheidt.info/images/aurora_oval.png
the New England Aurora isochasm zone is far northern than the mid-latitude aurora isochasms in Europe and Asia which correspond to the South of the United Stated of America zone down to Mexico. The isochasm figure above is quite clear.
In fact, from the figure above, the New England Aurora isochasm zone is more compatible with the Arctic zone III – from 55 to the polar circle.
Moreover, as it is clear from your own figure at
http://www.leif.org/research/Krivsky-Pejml-Aurorae.png
your extracted American record from Loomis appears very similar to your extracted record from Europe+Asia. Note the common peaks in 1730, 1790 and 1850, which form three 60-year cycles.
On the contrary, the New England Aurora record peak in 1880 and 1940, exactly like the auroras from Iceland.
Moreover, you need to think that it is very unlikely that the Faroes record is seriously erroneous, as you claim. In fact, for example between 1905-1920 at Faroes were observed an average of 50 auroras per year. During the same time in Iceland were observed less than 5-10 auroras per year, while in New England were observed about 25 auroras per year.
See figures here:
New England
http://www.landscheidt.info/images/newengland.png
Faroes and Iceland
http://pielkeclimatesci.files.wordpress.com/2011/11/pages-from-92rg01571.jpg
In particular, note the period 1910-1915:
New England does not see almost any Auroras, the same in Iceland.
On the contrary, at the Faroes about 30-40 auroras per year were seen.
Do you think that at the Faroes, all people were always drunk and were recording imaginary auroras that nobody in Iceland nor in New England could see?
It is evident that a catalog way be wrong because it is missing aurora events, not because it is recording imaginary auroras!
It is evident that Faroes are an anomalous place that makes those islands more compatible with the mid-latitude auroras in Europe. Perhaps this is due to the ocean currents around Faroes that change the magnetic properties of the zone.

Europe (Region l and ll) AND at the same time Region lV (America).
Apart from the time before 1776 when there were no American data, the criterion for including in the original catalog of 3878 entries was that [because of the AND] only simultaneous observations in Europe [E] and America [A] were included. So if in a months there were E aurorae on say the 1st, 5th, 10th, 17th, 22nd, and 30th, and A aurorae on the 2nd, 5th, 12th, 22nd, 27th, and 30th, only aurorae on the 5th, 22nd, and 30th would be included in the list. This guarantees that the list will contain exactly the same number of E and A observations, making it thoroughly mixed [as I said]. Now this applies only to the original catalog. The new data includes some 1500 new American observations that were added to the original list making the total 5380 entries.
“This[1996] supplement presented contains corrections and new data about occurrences of north polar aurorae (<55 degrees). New data are based <i>predominantly on the two Catalogues, i.e. of Loomis (LOO) and of Schroder (SC2). In the Catalogue Loo are collected the aurorae which were observed in North America.”.
Since in the old list there was an equal mix of E and A, adding 1500 new A means that the final list is now dominated by American observations [as I said]. So, Scafetta’s
If I overlay the New England Data (green line 1800-1948) over the Krivsky Data on Nicola’s graph (black line) there is an obvious divergence after 1850.
http://tinyurl.com/2dg9u22/images/world_silverman.png

The divergence begins ~1875 when the Fritz data ends. And is not between Nicola’s black line, but with his blues Faroe line, showing again that the Faroe data is not to be trusted. The green line follows the sunspot activity nicely, clearly showing the deep minima around 1700, 1760, 1810, 1900. Unfortunately the red curve has the obvious divergence after 1850, showing the breakdown of the correlation.
This is likely because the European data is being verified by the American data with the American data being the latter record that appears in the table.
The other way around: no Fritz data is included unless it verifies an American observation [your ‘AND’]. Bottom line is 1500 more new observations, almost all American [LOO and Ba].

The Faroes are quite opposite to the mid-latitude aurorae in Europe, e.g. the Danish aurora and Scroeder’s. But, you are right they are anomalous and shouldn’t be used. The reason for their strange behavior is simply the varying number of observers. In any case, your data in Figure 2B is dominated by American aurorae as I showed just above.

For this list the American entries are already folded into the list. There are 2345 new LOO entries. If those were just ‘verifications’ of existing Fritz entries then with the LOO there should be exactly the same number of entries if the LOOs have already been counted and ‘not a single new American observation was added. Yet the final list has 5281 entries or 5257-3878 = ~1400 new entries added from LOO, proving that not all the LOOs were just ‘verifications’ of existing entries.

November 25, 2011 9:18 pm

Leif,
you are mistaking the authors.
The purpose of the authors is to produce a record on mid-latitude large auroras observed in a large regions.
The catalog authors knew very well that the american auroras are different from the mid-low European Auroras. There are much more auroras in New England and north US (where the american auroras were collected) than in the mid-low latitude European-Asian auroras.
So, to make a consistent record they used a clear criterion based on multiple cross tests:
“The authors adopted the occurrences of aurorae on the basis of the following
criteria: possible recurrence after roughly 27 days, roughly since 1792 (and
partly also before) auroral data were adopted provided there was guarantee
that they were simultaneously observed in a larger geographical region. i.e.
provided they were recorded at a number of stations in Region I or II (i.e.
Europe), or in Region I or II and at the same time in Region IV (i.e.
America). ”
Note the sentence
“they were recorded at a number of stations in Region I or II ”
This means that if an aurora in a given day was recorded only in “one” or very few stations in Europe that aurora would not have been included in the original catalog. This criterion left out of the catalog a lot of European auroras that did not satisfy the ctiterion because recorded in just one or too few locations.
Once that the American catalog was used as reference, even if an aurora was recorded in just “one” European station, that aurora would have been listed in the catalog under the condition that also the American record had it. This added to the general catalog
2345 new entries which were references as LOO. These were not single american auroras, but auroras already present in the individual European+Asian catalogs which were not previously included in the general catalog because of the criterion requirement that the aurora had to be ” recorded at a number of stations in Region I or II “.
On the contrary all auroras seen in the USA, but not recorded in any mid-latitude European stations were excluded from the catalog because considered compatible with norther European auroras, not with the mid-latitude ones.
Thus, the catalog refers to auroras seen in mid-latitude Europe and Asia which partially overlap with the american one for which we can be sufficiently sure of their real occurrence or because simultaneously recorded in numerous European stations, or because symultaneously recorded somewhere in Europe+Asia AND in the USA.
Indeed, it is Silverman who in his figure 3, by improperly adding the mid-latitude aurora records to the new England ones has mixed apples and oranges. In fact, Silverman did not uses any serious criterion but simply added the two catalogs based on the simplistic claim that the New England Auroras were geografically located at mid-latitudes <55N, which is not the right criterion to follow.
In fact, as it is evident in this figure
http://www.landscheidt.info/images/aurora_oval.png
the New England Aurora isochasm zone is far northern than the mid-latitude aurora isochasms in Europe and Asia which correspond to the South of the United Stated of America zone down to Mexico. The isochasm figure above is quite clear.
"Plot the difference between the black and the green curve [show us] and you shall behold the divergence after ~1875."
The mid-latitude catalog did not stop in 1875, but in 1900. If the records were not reliable any more after 1875, the authors would have stopped in 1875, not in 1900.
Moreover, you still need to explain the patterns in the Faroes record. that show a pattern that is negative-correlation with the New England auroras and with the Iceland Auroras.
Were people in the Faroes always drunk to see a lot of imaginary auroras not seen in Iceland nor in New England? Note the huge difference between 1910 and 1915 during the solar minima.

As you point out only if there is a record from I or II AND an American record is the I,II record included.
This is not clear.
No, the other way around: For a European+Asian record to be used and American record has to exist on the same day
Incorrect as stated above.
The first rule only applies before 1776 where there were no American records. Otherwise the text would make no sense. These rules also only applies to the original list
This is your assumption (living in hope). The rules make perfect sense. European records can be validated by other European records OR by American records.
It does for the last deep dip. The LOO records are not cross checking as that rule only applied to the original list. The original list had 3878 entries [from 1700] and ended with Fritz in 1872. For this list the American entries are already folded into the list. There are 2345 new LOO entries. If those were just ‘verifications’ of existing Fritz entries then with the LOO there should be exactly the same number of entries if the LOOs have already been counted and ‘not a single new American observation was added. Yet the final list has 5281 entries or 5257-3878 = ~1400 new entries added from LOO, proving that not all the LOOs were just ‘verifications’ of existing entries.
Soo, the final list is dominated by American entries, because of the 2345 LOO entries that were added.

That is the most convoluted piece of text and what I can make of it you are making many assumptions.
The new LOO entries are verifying new European entries (1996) and possibly older European entries from the initial list that did not have a verification. The authors have set out clearly the prerequisites for all auroral records along with the naming convention in the table that you are ignoring. The American record if used to verify gets the “LOO” label in the table.

The authors are very clear […] There are no single records from America added to the list.
I have in my hand Fritz’s original list from 1873 covering Europe below 55N. It is instructive to look at an extract. Here are the first three months of 1850: http://www.leif.org/research/Aurorae-1850-Jan-Mar.png T
The columns are
Year, Month, Day, Fritz Cat, Krivsky Final Cat
An ‘F’ in the Fritz column means that there was an entry in Fritz’s list. An ‘F’ in the Krivsky column means that there was an entry marked ‘F’ in Krivsky’s list [and thus confirmed by another American observer than Loomis]. An ‘L’ means that there was a LOO, and an ‘S’ means the entry came from Seydl. As you can see there are 40 entries in the Krivsky list, and 21 of those are LOOs that are new [there are no entries on those days in Fritz’s original list] and thus added to the list.
1850 is not particular special, all the other years show similar behavior. So, the list is dominated by American entries.

The text is very clear that this is not the case. It does not make sense the say at I or II AND IV is required while at the same time I and be verified by II. The I and II only verify each other then there is no IV.
“As you point out only if there is a record from I or II AND an American record is the I,II record included.”
This is not clear.

As you say: “the authors are very clear”
This is your assumption (living in hope). The rules make perfect sense. European records can be validated by other European records OR by American records.
The text says AND.
” If those were just ‘verifications’ of existing Fritz entries then with the LOO there should be exactly the same number of entries if the LOOs have already been counted and ‘not a single new American observation was added.”
That is the most convoluted piece of text and what I can make of it you are making many assumptions.

No, I’m pointing out that under your assumptions there should be exactly the same number of entries. The goal was “auroral data were adopted provided there was guarantee that they were simultaneously observed in a larger geographical region”. You see, that there were many aurorae within the same narrow region does not satisfy the goal.

No, that is not the way it worked. Study the original list here: http://www.leif.org/research/Aurorae-1850-Jan-Mar-Original.png
and note that these were all recorded in to Krivsky catalog: http://www.leif.org/research/Aurorae-1850-Jan-Mar.png
the New England Aurora isochasm zone is far northern than the mid-latitude aurora isochasms in Europe and Asia which correspond to the South of the United Stated of America zone down to Mexico. The isochasm figure above is quite clear.
No, they are at most a few hundred km different and a strong aurora is visible over 1000 km.
“Plot the difference between the black and the green curve [show us] and you shall behold the divergence after ~1875.”
The mid-latitude catalog did not stop in 1875, but in 1900. If the records were not reliable any more after 1875, the authors would have stopped in 1875, not in 1900.
Moreover, you still need to explain the patterns in the Faroes record
I have explained that already: simply due to the number of observers varying with time.

At the most that would multiply all the numbers by a factor, not changing the general behavior of the time variation, such as making a minimum into a maximum.
In addition, I have shown just above that the Krivsky catalog is dominated by American aurorae an way. So your ‘analysis’ is basically done with American data.

Most of the aurorae in the catalog [region II] comes from England [cf. http://www.leif.org/research/Aurorae-1850-Jan-Mar-Original.png ] which as you can see on the isochasm chart http://www.leif.org/research/Isochasms-North-America.png lies in the belt from 5 to 25 aurorae per year where also New York and New England Lie. Mexico is in the 0.1-1 aurorae/year belt, corresponding to ~3 aurorae per solar cycle. As you know that is much lower than the frequency in Fritz’s region II, so you should not be so sloppy to claim that Northern European aurorae have the same frequency as in Mexico and Florida/Texas. If you look at your own Figure 2B you’ll see that the average frequency of [what you call European] aurorae is 27 aurorae per year, or 27 times larger than your ‘south of US’/Mexico isochasm.
Now, in the end, it doesn’t really matter that the catalog is dominated by American aurorae as great aurorae caused by geomagnetic storms are seen over a wide area, and geomagnetic storms are global phenomena.

An aurora is added to the list only if it satisfies one of the following condition:
1) it is observed in Region I AND Region II
2) it is observed in Region I AND Region IV
3) it is observed in Region II AND Region IV

Geoff thinks the authors are very clear. But you obviously misread them, so they wee not so clear.
The statement in the text was: “provided they were recorded at a number of stations in Region I or II (i.e. Europe), or in Region I or II and at the same time in Region IV”
Your first condition is clearly wrong, because the real condition is that the aurora is observed at a number of stations in region I or II. Since there are ten times fewer aurora in region I than in II [check the isochasm map], using the AND condition would reduce the number of accepted aurorae by a factor of ten down to just a handful of records per solar cycle, which clearly is not the case.

November 26, 2011 10:39 am

Leif,
Loomis (LOO) catalog includes a lot of mid-latitude European auroras, not just American one.
Loomis, in fact, did not want to prepare just a local US catalog but a more global one as it is clear in his work.
LOOMIS E.: Comparison of the mean daily range of the magnetic declination and the number of auroras observed each year, with the extent of the black spots on the surface of the sun. Am. Jour,. Sci. Arts, Ser. III, Vol. V, No 28, 1873, 245.
So the series LOO refers mostly to mid-latitude European Auroras. In fact the chosen boundaries are: “as the eastern boundary the meridian of 40 degrees of longitude east from Greenwich; and as the western boundary the meridian of 80 degrees of longitude west from Greenwich”
These boundaries mean from European Russia to Atlantic USA. Indeed, LOO catalog was predominally made using all European catalogs available to Loomis plus a selection of american catalogs for comparison.
http://books.google.com/books?id=Ub8EAAAAYAAJ&pg=PA245&lpg=PA245&dq=Comparison+of+the+mean+daily+range+of+the+magnetic+declination+and+the+number+of+auroras+observed+each+year&source=bl&ots=H8YV6C6dq1&sig=AwV2-ycgWqrJoq3go53VYFZKgFI&hl=en&ei=SyLRTt7WDMqgtweThKG5DQ&sa=X&oi=book_result&ct=result&resnum=2&ved=0CB8Q6AEwAQ#v=onepage&q=Comparison%20of%20the%20mean%20daily%20range%20of%20the%20magnetic%20declination%20and%20the%20number%20of%20auroras%20observed%20each%20year&f=false
So, your claim that the LOO record refers to America auroras alone is blatantly false.
Indeed, LOOMIS excluded a lot of US auroras from his catalog because not consistent with his European catalogs physical properties.
Moreover, the fact is that from 1875 to 1900 we have a lot of additional catalogs from mid-latitude european stations that do not record many auroras such as Mo, S, R, Sc2, Ba, JB, BF. These catalogs agree with the Faroes one, which records few auroras during that period.
And the authors of the catalog were very careful in not mixing the mid-latitude aurora from Europe with auroras from other eegions characterized by different physical properties.
So, atthe conclusion the issue remain the same, Leif.
You may believe that the records that I used are wrong, but the records show what they show.
Of course the records may also be wrong as you claim, but util now you have not proved them to be wrong, and your claims , when not openly rebutted herein, remain to be only your unproved personal opinion.

So, your claim that the LOO record refers to America auroras alone is blatantly false.
It is not my claim, but the claim of the authors that compiled the catalog you used:
“New data are based predominantly on the two Catalogues, i.e. of Loomis (LOO) and of Schroder (SC2). In the Catalogue LOO are collected the aurorae which were observed in North America.”
Loomis included aurorae from Europe, namely the same as Fritz had, as they both drew from the same sources. As you can see here http://www.leif.org/research/Aurorae-1850-Jan-Mar.png there are, indeed, some that correspond. But that is a minority.
Indeed, LOOMIS excluded a lot of US auroras from his catalog because not consistent with his European catalogs physical properties.
Where does it say that? He excluded data from the Western US because of their sparseness.
Loomis says he got his pre-1868 data exclusively from Lovering. Siscoe reports in RG018i003p00647 that “Lovering demonstrated the close similarity between auroral variations recorded in Europe (by others) and in America”
In his memoir, Lovering asks after having described observations in Europe: “It may be interesting to inquire how the case [occurrence of aurorae] stands in the western hemisphere” and proceeds to do just that. He collect the observations of Americans Winthrop, Holyoke, Wigglesworth, Hale, and many others. This shows where Loomis got most of his observations from. Although one can debate forever the details [without having the original sources], it is clear that the data in Krivsky’s catalog that you used is thoroughly mixed between Europe and America, which in a sense is fine as there is no real difference between them [geomagnetic storms causing the aurorae being global phenomena]. What is false is your claims that the catalog is ‘primarily’ European data. It is not.
Nicola Scafetta says:

An aurora is added to the list only if it satisfies one of the following condition:
2) it is observed in Region I AND Region IV
3) it is observed in Region II AND Region IV

Except that of the scant 114 records from 1875-1900 the “Ba” records come from Yerkes in the US…
In http://www.leif.org/EOS/Bentley-Aurorae.pdf Silverman and Blanchards reports on the remarkable 49-yr series 1883-1930 by the dedicated observer William Bentley at Jericho in Vermont of 634 aurorae, showing the dramatic minimum 1900-1920 in accordance with all observations elsewhere, except the faulty Faroes data. http://www.leif.org/research/Bentley-Auroral-Data.png

As I pointed out The Vermont data agrees well with European data from the same geomagnetic latitude [57N], e.g. http://www.leif.org/research/Denmark-Vermont-Aurorae.png as well as Iceland data. Faroes disagree. http://www.leif.org/research/Scafetta-Figure-2B.png

So the series LOO refers mostly to mid-latitude European Auroras.
Although I have shown that this is not the case, there is simpler argument. The isochasm maps show that the frequency of aurorae in mid-latitude Europe is between 1 and 25 aurorae per year [one chart] or between 1 and 10 per year [the older chart]. A reasonable overall rate is a number well less than 10 [because of the non-linear variation], say 5. If the Krivsky catalog is dominantly European entries, then during the 200 years from 1700 to 1900 there should have been 5*200 = 1000 entries. In fact, there are more than 5000, or 5 times as many. This is consistent with the isochasm values for New England [or the 60N for Fritz’s region IV] being 20-30, showing that the catalog is mostly American data. This simple argument is so compelling as to make all the rest of your squirming irrelevant. But, as I said, that is OK, as geomagnetic storms [causing aurorae in mid-latitudes] are global. What that means is that the shape of the variation with time is the same, just the amplitude varying with latitude. This holds as long as you are well equatorwards of the auroral zone. At the oval, there is always an aurora, and well polewards of the oval, the frequency decreases to a minimum at the geomagnetic pole. This has been known for more than a century.

November 26, 2011 4:33 pm

Leif,
I am sorry but about the LOO record you just sunk very deep in the ocean.
In addition, as I explained above the fact is that from 1875 to 1900 we have a lot of additional catalogs from mid-latitude european stations that do not record many auroras such as Mo, S, R, Sc2, Ba, JB, BF. These catalogs agree with the Faroes one, which records few auroras during that period.
On the contrary we have a lot of auroras detected at the Faroes from 1900-1920, while very few auroras were deteted in New England and Iceland.
You have not responded my questions.
1) Do you think that in 1900-1920 at the Faroes all people were always drunk to see a lot of auroras (40 per year) that did not exist?
2) Do you think that everybody was blind or was sleeping in mid-latitude Europe from 1875-1900 so that very few auroras were recorded during that period in that period?
So, where are the catalogs from mid-latitude Europe that show that during the period 1875-1900 a lot of aurora were seen during that period in that region? Do you have them? yes or not?
Moreover, also LOO record apparently excludes the Denmark auroras and those auroras are excluded from the mid-latitude count in general. LOO excluded several US catalogs and other catalogs not because they were just sparse but because the frequency of auroras seen in those regions , during the periods when the data were available, did not match the frequency of the European mid-latitude auroras.

I have in my hand Fritz’s original list from 1873 covering Europe below 55N. It is instructive to look at an extract. Here are the first three months of 1850: http://www.leif.org/research/Aurorae-1850-Jan-Mar.png T
The columns are
Year, Month, Day, Fritz Cat, Krivsky Final Cat
An ‘F’ in the Fritz column means that there was an entry in Fritz’s list. An ‘F’ in the Krivsky column means that there was an entry marked ‘F’ in Krivsky’s list [and thus confirmed by another American observer than Loomis]. An ‘L’ means that there was a LOO, and an ‘S’ means the entry came from Seydl. As you can see there are 40 entries in the Krivsky list, and 21 of those are LOOs that are new [there are no entries on those days in Fritz’s original list] and thus added to the list.

This proves nothing and still shows you do not understand the selection criteria. If the original Fritz entry is confirmed by ANY other entry (being station or different region) the confirming entry is stated in the Krivsky table.
If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned.“
This convention must have been used for other original European entries other than Fritz.
Your table excludes the possibility of non Fritz European entries being the initial entry. Most of the reference material consists of European data. The Fritz data being a compilation is also capable of confirming itself. Can you post a link for the entire Fritz data.

You can’t read? There is not a lot. There are a scant 114 records all together, and the ‘Ba’ you mention contains 28 of those and is from Yerkes in the US.
On the contrary we have a lot of auroras detected at the Faroes from 1900-1920, while very few auroras were deteted in New England and Iceland.
No, you have a lot of aurorae reported, not detected. This is likely due to an increase of the number of observers during that time. Since the Faroes are south of Iceland, they must see fewer aurorae unless the auroral zone has expanded very much, which would have meant that Denmark and New England would have seen an excess which they didn’t. Aurorae are associated with currents in the magnetosphere and geomagnetic activity was at an all-time low, so not many aurorae.
1) Do you think that in 1900-1920 at the Faroes all people were always drunk to see a lot of auroras (40 per year) that did not exist?
No, but I think more were looking and then interest waned or funding ran out..
2) Do you think that everybody was blind or was sleeping in mid-latitude Europe from 1875-1900 so that very few auroras were recorded during that period in that period?
No, but solar activity was declining and and street lighting was increasing.
So, where are the catalogs from mid-latitude Europe that show that during the period 1875-1900 a lot of aurora were seen during that period in that region? Do you have them? yes or not?
I have a catalog from Angot [1895] which lists 323 aurorae for 1875-1890 alone for Europe below 55N. Many more than the 42 that are in the Krivsky compilation for the same interval, so activity was not small at all.
Moreover, also LOO record apparently excludes the Denmark auroras and those auroras are excluded from the mid-latitude count in general.
As are the Faroes aurorae. So if Denmark should not be considered, that would be even more the case for the Faroes on account on their higher latitude [62N].
LOO excluded several US catalogs and other catalogs not because they were just sparse but because the frequency of auroras seen in those regions , during the periods when the data were available, did not match the frequency of the European mid-latitude auroras.
Where does it say that? I don’t think so. LOO excluded some that were at too high latitude as was proper.

That is not what they say. Again: 1) if there were more than aurora for a day in II [‘I’ doesn’t matter as there are so very few of them] for a day, that day is a confirmed entry. 2) If there were only one in II, but that day was also in IV, the entry is confirmed.
This convention must have been used for other original European entries other than Fritz.
Your wishful assumption. Text text says specifically Fritz and no other was mentioned.
Your table excludes the possibility of non Fritz European entries being the initial entry.
The text excludes that as it only talks about Fritz.
Most of the reference material consists of European data.
For the initial 1988 list, but not for the supplementary entries. You can see directly from the sample data below, where every LOO entries are used to validate Fritz entries, but where most LOO entries don’t even have a Fritz entry and thus were not seen in Europe.
The Fritz data being a compilation is also capable of confirming itself.
Of course, if there are several aurorae on a given day.
Take the example I gave you: http://www.leif.org/research/Aurorae-1850-Jan-Mar-Original.png
On Jan. 5 [1850] there was only one sighting (Greenwich) so not confirmed by another entry, but since it is on Krivsky’s list it must have been confirmed by a region IV [American] entry, and sure enough there was a LOO entry for that day. http://www.leif.org/research/Aurorae-1850-Jan-Mar-png
On Jan 19 there was only one sighting [Ship 50N,26W] so not confirmed by another entry but since it is on Krivsky’s list it must have been confirmed by a region IV [American] entry, and sure enough there was a LOO entry for that day.
On Jan 30., same thing
On Jan 31., same thing
On Feb 3., same thing [interesting enough there are two entries for that one day in Krivsky’s list…]
On Feb 6., there are three sightings so the day is confirmed, no region IV needed, and sure enough there was no LOO entry for that day.
On Feb 9-12, 18, there were only one sighting on each day, so the entries cannot be confirmed unless there was a region IV sighting on each day too [which there then must have been, otherwise the day would not have been on the list]
On Feb 23., here were two sightings, one from region II and one [Parma] from region I [this is the only region I – south of 46N in the entire sample] so the day is confirmed.
And so on.
Can you post a link for the entire Fritz data.
I printed it out from Angot’s book. Google ‘angot aurora’. The link you wnat is the first one on the page. The appendix contains the entire Fritz list for regions I and II [only].

De profundis then:
In http://www.leif.org/EOS/JA085iA06p02991.pdf Silverman and Feynman comments:
“The nonlocal nature of the change in auroral occurrence frequency is confirmed by comparing the Swedish data with data from New England, collected by Loomis [1866], who was one of the pioneers of American auroral research in the nineteenth century. His data were culled from published sources such as journal articles and observatory reports. Figure 5 shows the number of auroras reported per year in Boston and New Haven. We note that from about 1792 to about 1836 almost no auroras were seen, but that before and after those times auroral sightings were very frequent. When the data from Sweden and Boston-New Haven are superposed, as in Figure 6, the agreement is remarkable. When auroras were seen predominately in southern Sweden, they were also seen in New England, which is at more southerly geomagnetic latitude. When they were seen more frequently in northern Sweden, they were rarely observed in New England. Since the change in auroral pattern took place simultaneously at two such widely separated locations, the cause must be in the driver of the aurora, the solar wind.”

November 26, 2011 7:53 pm

Hi Leif,
well you say “I have a catalog from Angot [1895] which lists 323 aurorae for 1875-1890 alone for Europe below 55N. ”
Angot ‘s catalog is here
http://books.google.com/books?id=UD4XAAAAYAAJ&pg=PA32&lpg=PA32&dq=Angot+auroras&source=bl&ots=frz-8qzB9d&sig=cWQbn5uwANx_zW6ODJBCg7WPVtI&hl=en&ei=UaPRTv2pBsKatweYwZGtDQ&sa=X&oi=book_result&ct=result&resnum=1&ved=0CCEQ6AEwAA#v=onepage&q=Angot%20auroras&f=false
A lot of those auroras were seen in just one location and would not fit the criterion for being added to the general catalog: an aurora must been see in a number of locations, not just in one place.
So let us not add apples and oranges.
I get these numbers of auroras per year, when at least two locations record the same event
1875 -1
1876 -4
1877 -0
1878 -0
1879 -0
1880 -2
1881 -10
1882 -~20
1883 -6
1884 -4
1885 -7
1886 -2
1887 -3
1888 – 6
1889 -3
1890 -7
It does not seem to be much! just about 75 in 16 years = 5 per year. Like the general catalog that I use.
Moreover, numerous observations were made in the middle of the Atlantic probably on ships. These auroras may not fit the criterion for the auroras seen on the land because the ocean get really dark and even faint light are seen. In any case, the middle Atlantic record needs to be added also to the other catalogs for a proper comparison. So let us not add apples and oranges., OK?

November 26, 2011 8:01 pm

Moreover, the auroras seen on the ships in the Atlantic are problematic because their frequency is directly related to the trafic on the ocean that has significantly increased in time. So, if you want to use a catalog with a lot of ship records there is the need to opportunely normalizing it in function of the traffic intensity. So, there is a bias
On the contrary, the observation on the land are fixed.

November 26, 2011 8:08 pm

Well Leif, you have discovered that
“When auroras were seen predominately in southern Sweden, they were also seen in New England, which is at more southerly geomagnetic latitude. When they were seen more frequently in northern Sweden, they were rarely observed in New England.”
This confirms my results in the paper that Northern and Southern regions act in the opposite way!
When a lot of Auroras are seen in Iceland less aurora are seen at the Faraoes (or mid-latitudes), when less Auroras are seen in Iceland more auroras are seen in Faroes (or mid-latitudes). 🙂

That criterion was only applied to the Fritz list, not to the LOO data. And not to the ‘Ba’ list. And close study throws doubt on the use of the criterion overall. In 1850 all [except 2] of the entries in Argot [which is actually just the original Fritz] ended up on Krivsky’s list even though most of them only had one aurora on the day [two conclusions possible: 1) the criterion was not used, or 2) for every one on Fritz’s European list there was also a matching one on his region IV list). Pick your poison].

“When auroras were seen predominately in southern Sweden, they were also seen in New England, which is at more southerly geomagnetic latitude. When they were seen more frequently in northern Sweden, they were rarely observed in New England.”
This also implies that New England is more compatible with southern Sweden than with the Mid-latitude auroras which are still more south

November 26, 2011 8:25 pm

“Angot’s list is a copy of Fritz’s list until 1872, so Fritz used those same ships too. OK?

No, Leif. The ships from 1875 to 1890 are by far the majority of the records while before 1975 there are very few ships and almost all records are from lands

Leif Svalgaard says:

You are starting to see the format where the European data is being validated by other Euro data OR LOO data, but you are missing another important point I think.
For the initial 1988 list, but not for the supplementary entries. You can see directly from the sample data below, where every LOO entries are used to validate Fritz entries, but where most LOO entries don’t even have a Fritz entry and thus were not seen in Europe.
Here you are assuming that the LOO entries are only validating Fritz entries. The LOO entry is capable of validating ALL European entries.
This convention must have been used for other original European entries other than Fritz.
——————————————————
Your wishful assumption. Text text says specifically Fritz and no other was mentioned.

Not wishful thinking, there is only ever one name in the data table. Are you suggesting that Krivksy adopted another convention for other data sets?

November 26, 2011 8:29 pm

So, you cannot add a ship record to a record that is made mostly of land observations. Do not mix apples with oranges.
In Angot ‘s catalog after 1875 there are every few land observations

When a lot of Auroras are seen in Iceland less aurora are seen at the Faraoes (or mid-latitudes), when less Auroras are seen in Iceland more auroras are seen in Faroes (or mid-latitudes). 🙂
The facts are: when the oval is over Iceland there are many aurora there and few in the Faroers and south thereof [mid-latitudes]. If the oval shifts to the Faroes there will be fewer in Iceland and more in New England and Denmark and South thereof. But in 1900-1920 there were fewer aurora in Denmark and New England. Furthermore 1900-1920 were areas with very low solar activity so the oval if anything would have shifted north of Iceland with meaning fewer aurora over Iceland, Denmark, Southern Sweden, and New England as observed.

Not the polnt. Fritz had no problems using ships. And using ships would in any case give a truer view as European observers were increasingly hampered by street lights.

November 26, 2011 8:46 pm

Leif,
you still do not undestand the logic of my paper. Don’t you?
As I said you many times you need to look at the auroras at the mid-latitudes at the 11-year solar cycle minima. And you will see the 60-year cycle. Look at the peak data in 1845. That peak in mid-latitude auroras during the solar mimimum can be explained only if the auroral oval shifted very south during that period.
The auroral oval shifts for multiple reasons, not just by one reason as you think.

Here you are assuming that the LOO entries are only validating Fritz entries. The LOO entry is capable of validating ALL European entries.
As you can see they were only used to validate Fritz entries. And the LOO entries as I have shown were New England data. As noted earlier:
In http://www.leif.org/EOS/JA085iA06p02991.pdf Silverman and Feynman comments:
“The nonlocal nature of the change in auroral occurrence frequency is confirmed by comparing the Swedish data with data from New England, collected by Loomis [1866], who was one of the pioneers of American auroral research in the nineteenth century. His data were culled from published sources such as journal articles and observatory reports. Figure 5 shows the number of auroras reported per year in Boston and New Haven.
No matter how this is sliced the simple fact remains that the catalog used by Nicola is in no way European data only, but by the very nature of the construction and the validation used, a thorough mix from both regions, and that is the point.
Are you suggesting that Krivksy adopted another convention for other data sets?
I go with what he says. Not with what one might assume.
Nicola Scafetta says:

So, you cannot add a ship record to a record that is made mostly of land observations. Do not mix apples with oranges.
Fritz had no problems doing that, and I don’t have either.

Your paper does not have any logic, just invalid use of bad data.
As I said you many times you need to look at the auroras at the mid-latitudes at the 11-year solar cycle minima. And you will see the 60-year cycle. Look at the peak data in 1845. That peak in mid-latitude auroras during the solar mimimum can be explained only if the auroral oval shifted very south during that period.
The oval does not shift very south during solar minima. The position of the oval is determined by the properties of the solar wind only and the oval contracts during low solar activity. And the data you are plotting are dominated [as I have shown here repeatedly] by New England data. At low solar activity auroral activity decreases everywhere south of the oval. In the oval flows millions of amperes; the magnetic effect from these currents are very easily measured at ground-level [can even induce currents to explode transformers and corrode pipelines] Here is the signature of these currents measured at mid-latitude stations all over the world: http://www.leif.org/research/Ap-Monthly-Averages-1844-Now-png and their power spectrum http://www.leif.org/FFT-SSN-Ap-Temps.png [no hint of 60-yr cycle in either the currents or in the sunspot number, but well in the global temperatures, reflecting the well-known PDO-cycle]
The auroral oval shifts for multiple reasons, not just by one reason as you think.
No, we can quantitatively determine the position of the oval from known physics. There are no other reasons.

What peak? There were only 18 aurorae on Fritz’s European list of which 14 were singletons, so only 4 that should be listed according to the criterion of there being more than one for inclusion in the table. Actually 9 made it [possibly because of some region IV aurorae from New England]. Do you call this a peak? Now, the LOO list added another 41, now we have sort of a peak, but that came from New England, and BTW, minimum was in 1843, not in 1845.

November 26, 2011 11:08 pm

While Leif continues to place his own assumptions on Krivsky’s data, here are some interesting excerpts from Loomis’s book.
“The range of the maxima and minima of auroral displays is considerably greater than that of the solar spots, and the observations of magnetic declination seem to indicate a similar peculiarity. There seems then to be no room for doubt that auroral displays exhibit the ten yearly period of solar spots, but the range of the changes on different years is subject to influences which may be independent of the sun.
“The successive maxima of auroral displays are more variable than those of the solar spots, so that the ten-yearly period might be easily overlooked, and it might be inferred that the maxima only occurred at intervals of about 60 years.”
BTW I attempted to contact Krivsky, but it appears he may have passed away in 2007. It would be good to have a copy of his 1996 supplement.

November 27, 2011 1:07 am

1850 is an interesting year. The Krivsky data tells us 136 aurora for the year. The Fritz data gives us 142 (if I counted correctly) possible aurora. Around 62% of the Krivsky data has LOO listed for 1850. This is an obvious example of the American data only appearing as a reference because it also had auroras on the same day.
The LOO data label is very prevalent around 1850, but as shown earlier the New England data from Silverman which should mirror the Loomis data is very different in most places when comparing the green line (Silverman) and the black line (Krivsky). The New England 1850 record is much lower than the European record (about 90 compared to 136) with the total Loomis count coming in at around 85. This shows a big disconnect between Europe and America. A comparison of Silverman and Loomis would be interesting.

November 27, 2011 2:00 am

Bad use of the bold tag previously.
Leif seems to think the Krivsky record is all about Fritz and Loomis. An example of Krivsky’s procedure is 1850 Feb 26. The Fritz record is blank, but the table records Seydl from the Czech region. The Seydl record must be from the first Kravsky list as the paper is recorded with the 1988 Krivsky record, which means another European record other than Fritz must exist on the same day.

November 27, 2011 8:53 am

Sorry, Leif.
But everything looks more complex than what you believe.
Unfortunately, you continuously improperly mix data from physically non-homogeneous regions (mid-lat Europe, New England, Atlantic, etc) to support your faith and you reject the actual data because they do not fit your faith.
As also Geoff noted above, people expert in these data have many times acknowledged that the aurora records show a complex dynamics that cannot be simply reproduced by the sunspot number record.
Your theory is too simplistic. Accept it, and move on.
As I said above and explained in my paper the auroral oval moves south and north with apparently a 60-year cycle because of additional reasons than just sunspots! This pattern is very clear if you look at the curve connecting the aurora at the sunspot number minima.
Moreover, as explained above, even your German record support my assumption.
These are the recorded aurora during solar minima from 1951 to 1954 in Germany
—————–Kp
01/05/51 —–7
02/05/51 —-7
25/09/51 —–8
07/10/51 —–8
28/10/51 —–9
These are the recorded aurora from 1961 to 1964
——————–Kp
08/01/61 ——4
04/02/61 ——7
17/02/61 ——-6
26/05/61 ——-4
17/07/61 ——-6
11/08/61 ——-5
11/10/61 ——-4
28/10/61 ——-3
10/01/62 ——-6
29/06/62 ——-3
28/07/62 ——-4
24/10/62 ——-5
29/07/63 ——-3
30/07/63 ——-5
03/10/64 ——-4
As you can easily see from the above numbers, the data agree with my expectations, not with yours. In fact, not only in 1961-64 we see much more german aurora than during the period 1951-1954 as my model predicts, but we often see them also with a very low Kp index 3, 4, 5 and 6 and always below Kp=8 which do not fit at all your theory of Kp>=8 for Germany (not even with the several hundred kilometer hypothesis jump, which should be more than 1500 Km to cover the 10 necessary degrees).
It is evident from those data that the auroral oval moved south from 1950 to 1965 for reasons different from Sunspots, so that also weak auroras with a very low Kp index could reach the mid-low latitudes in Germany despite the numerous and strong german street lights.

1850 is an interesting year. The Krivsky data tells us 136 aurora for the year. The Fritz data gives us 142 (if I counted correctly) possible aurora.
It seems you are confusing ‘aurora’ with ‘days with aurora’. Let me explain, if on April 1, 10 aurora were seen at different people or places, and on April 2, 15 were seen, then there were 2 days with aurora, but 25 aurora seen. For 1850 the Fritz list for Europe [cited by Angot] had 60 days with aurorae (most singletons), not 142 days.
Around 62% of the Krivsky data has LOO listed for 1850. This is an obvious example of the American data only appearing as a reference because it also had auroras on the same day.
There were 87 days with aurorae from the LOO list, all of which are from New England. Since Fritz only had 60 days with aurorae, any American data can at most confirm 60 days. Since Krivsky lists 136 days with aurorae for 1850, at most 60 of those can be from Europe, the rest [plus all of those used for confirmation] are from New England, thus confirming that the Krivsky list is dominated by American entries.

Perhaps Seydl recorded two aurora on that day. Or perhaps Krivsky didn’t follow his rule. He apparently didn’t do so for Jan. 31st, either, or Feb. 18, or Mar. 9th, and so on. As these have only one aurora in the Fritz list, and would thus not qualify.

November 27, 2011 11:52 am

@ Leif, “I mix nothing, you are using the catalogs that are mixing data from different regions. ”
the catalogs that I used are made with appropriate criteria that you are not using in your personal mixing. There is a difference in mixing things without criteria and with criteria.
you continuously improperly mix data from physically non-homogeneous regions (mid-lat Europe, New England, Atlantic, etc) to support your faith and reject the data that contradict you. This is not a serious way of acting, Leif.
1) First you appealed to a German aurora record, when I prove to you that it supports me, you have abbandoned it.
2) You continuosly insisted that New England and Germany are equivalent for the Auroras. Then Geoff and I proved to you that New England is compatible with norther regions such as Denmarck and Norway and Sweden.
3) you continuously insisted that Loomis record was made of American auroras alone. Then I proved to you that it is made of mostly European catalogs.
4) You claimed to have found a lot of mid-latitude auroras from 1875 to 1890 in the Angot’s list . Then I proved to you that by far the majority of those auroras come from the middle of the Atlantic and are physically incompatible with the land auroras because the aurora visibility in the open ocean is far superior than on the land, moreover, those auroras frequencies are function of ship traffic patterns and trends, so this record cannot be simply added to the land auroras but needs to be carefully calibrated to take off several biases, before a comparison can be properly made.
It is evident that the things are more complex than what you believe.

2) You continuosly insisted that New England and Germany are equivalent for the Auroras. Then Geoff and I proved to you that New England is compatible with northern regions such as Denmark and Norway and Sweden.
You did not do any such thing. Norway is too far north, southern Sweden and Denmark dip into the less than 55N area and behave just like it.
3) you continuously insisted that Loomis record was made of American auroras alone. Then I proved to you that it is made of mostly European catalogs.
Again, you did not do that. Read his catalog.

His data were culled from published sources such as journal articles and observatory reports.”
From the Sisco review RG018i003p00647: “Lovering demonstrated the close similarity between auroral variations recorded in Europe and in America. Fritz and Elias Loomis [Loomis, 1873] in the United States separately established that the variations in the frequency and intensity of the aurora conform closely to variations in solar spottedness.”
He compared his data with European catalogs from the area he outlined and concluded that his New England data were very similar to the European data. The authors of the catalog you are suing states specifically: ““This supplement presented contains corrections and new data about occurrences of north polar aurorae (<55 degrees). New data are based predominantly on the two Catalogues, i.e. of Loomis (LOO) and of Schroder (SC2). In the Catalogue LOO are collected the aurorae which were observed in North America. So entries in your cataloig marked LOO are from North America.
4) You claimed to have found a lot of mid-latitude auroras from 1875 to 1890 in the Angot’s list . [..] the aurora visibility in the open ocean is far superior than on the land
And thus closer to the REAL number of aurorae. Anyway Fritz had no problems with ships and don’t either.
It is evident that the things are more complex than what you believe.
Bad data and bad logic and deficient knowledge always make things look complex, and even bewildering. In the cold light of valid data and sound physics, things make more sense.

Your graphic conceals more than reveals. Here is a better comparison: http://www.leif.org/research/Auroral-Frequencies-per-Year.png
The blue curve shows all of Silvermans 20602 New England aurorae in bins of one year [simply counting how many anybody saw everywhere in each year]. This shows the combined effect of real effect and varying number of observers, with the typical curve fitting the lower boundary http://www.leif.org/research/Numbers-of-Observers-Influence.png .
The pink curve is counting the days per year when one or more aurorae were seen [also showing, of course, an effect of varying number of observers]. BTW, the Bentley 1883-1931 data were not included but they match the blue curve closely anyway.
The brown curve is the most interesting. It shows the number of days with aurorae in the updated Krivsky & Prejml mixed catalog used by Scafetta. It matches the Silverman New England curve very well until the end of Lovering’s catalog [showing how auroral frequency is a global thing, depending one the same cause: the solar wind as disturbed by solar flares and CMEs]. Loomis used Lovering’s data when available and reported somewhat fewer thereafter. The blue arrow shows the end of the Fritz and Loomis catalog, at which time the ‘bottom fell out’ of the Krivsky data. The conclusion is clear: the Krivsky catalog after 1872 is useless as it is much too low. The Krivsky catalog before that is dominated by the American data [partly because there are more of those on account of New England being at a slightly higher isochasm]. I think we can now put the whole thing to rest with confidence, unless you wish to fight some rearguard action, slowly petering out.

You are still assuming that the LOO records can only confirm Fritz records, They can also confirm the Seydl and other European records of the year.
The LOO record is not clear, you state 87 for 1850 which looks right on the Krivsky data, but according to the Loomis book there are 36 auroras recorded at Boston and New Haven during 1850. I have 19 pages of the book which looks to be the total amount of pages but wonder if there is more, there does not seem to be daily data. I have found a copy of the original book online for $40.00 if anyone is interested.

Counting Lovering for 1850 I get 90 days with aurorae [plus minus a few – these are hard to count], which shows that the LOO records are just Lovering.

I think [from the evidence] that the confirmation business was only done for the original list. And that the LOO records were just dumped in there, overwriting whatever occasional Fritz records there might have been here and there. The number of LOO records seems to match the Lovering counts closely. It is unlikely that there were a matching Fritz or Seydl record for every LOO record, and if there were, it would just prove that the list is thoroughly mixed which has been my point all along. Pick you poison.

November 27, 2011 5:59 pm

See, Leif.
although the mid-latitude aurora record may be incomplete since 1872,
untill you explain the patterns in the Faroes record that starts in 1872 and merges quite well with the other record as shown in the figure your argument may be inconclusive.
New England auroras are located too north and in another place, and the solar activity was increasing since Dalton minima, which may have changed the patterns and may explain the divergence observed in the data since 1850.
Angot’s list after 1880 contains too many Atlantic auroras at latitude norther than 40N , which are also located too north because the mid-latitude European Auroras would correspond to Atlantic latitude lower than 42N in the middle atlantic beteen Europe and USA. Those Atlantic auroras may be more compatible with the New England ones.
So, the issues may be fully resolved only by carefully trying to build an updated aurora catalog.
The fact thatthe aurora oval can expand and contract and other patterns may explain a divergence of the dynamical patterns and negative correlations among the records.
Then there are many other issues that need to be explained at the same time concerning the properties of these cycles in other solar and climatic records and in the records before 1700, etc.
So, the issue needs to be interpreted according to the big picture.

Do you have evidence that there are few European records other than Fritz that occur during 1850. They are available from the original and supplementary data. There may be a lot of European records that were not confirmed in the first past. The explanation text does state that the verification process applied to other records outside of Fritz.

Your graph asks more questions than perhaps giving answers.
The LOO data in Krivsky by eyeballing is stated in around 50-60% of the cases from 1770-1872.
1. If your assumption that the LOO data is adding to the European record why does the Silverman/Krivsky data not diverge greatly before 1850.
2. If your assumption that the LOO data is adding to the European record why does the record between 1850 and 1872 show the Krivsky data much lower than the Silverman New England data. If the LOO data was adding you would expect it to over power the SIlverman Data. (the number of observers is not a strong argument).
3. The Krivsky data between 1872 and 1900 does perhaps look suspect. Angot continues the European record after 1872 (with a fairly high proportion of ocean sightings) that does show a fall after 1872 but also shows a rise after 1880. Maybe the Krivsky record is incomplete from 1872 to 1900. A graph of the Angot complete data might be helpful.

The Faroes record is opposite to all other records.
Angot’s list after 1880 contains too many Atlantic auroras at latitude norther than 40N , which are also located too north because the mid-latitude European Auroras would correspond to Atlantic latitude lower than 42N in the middle atlantic beteen Europe and USA. Those Atlantic auroras may be more compatible with the New England ones.
Nonsense, the Kp=7 line that determines where aurorae can be seen overhead with the same frequency as in Germany and England in the middle Atlantic is well north of 50N: http://www.swpc.noaa.gov/Aurora/globeNW.html
So, the issues may be fully resolved only by carefully trying to build an updated aurora catalog.
One should not draw premature conclusions on a catalog that is in doubt. It will probably be impossible to improve on existing catalogs as there is no new data. But since we know that there are currents associated with aurorae and we know the strengths of those currents back to the 1830s, we can calculate what the auroral record will look like. The existing aurorae catalog are too dependent on number of observers and things not under control to be useful, except in a very general sense.
The fact that the aurora oval can expand and contract and other patterns may explain a divergence of the dynamical patterns and negative correlations among the records.
How the oval expands and contract is well-known and completely understood.
So, the issue needs to be interpreted according to the big picture.
No, the issue must be interpreted in according to the data and the well-known physics.

Do you have evidence that there are few European records other than Fritz that occur during 1850.
Fritz did a very thorough job and it is unlikely that a large number of non-Fritz records exists. But even if every record marked LOO had an unknown European record to match, it would still mean that the catalog is a thorough mix which is what I trying to show. I would gladly assume with you that every LOO record was just a confirmation of an unknown European record, because that would mean a complete mix. Are you ready to agree with that?
The explanation text does state that the verification process applied to other records outside of Fritz.
No, it says “If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned”. No other records than Fritz’s.
I am just reading of the data table in the Loomis book (36). The 87 LOO records from Krivsky is your figure.
No, they are Krivsky’s
We seem to have no verification of the actual LOO data. In his book he states many areas of reference for aurora.
Yes, he used the others to verify that the New England aurorae in his catalog [mostly drawn from Lovering] behave just like the European records.
http://tinyurl.com/2dg9u22/images/loomis1.png
He says: “In the Vierteljahrsschrift, vol 10, p.232 [I have that book and that catalog] is given a very complete catalog of European auroras classified by parallels of latitude, and I have used this as my principal basis in the subsequent comparisons”. He did not, of course, include them in his own list. For once, because the the list in Vierteljahrsschrift [compiled by Rudolf Wolf] gives yearly counts only.
Wolf writes: [my translation from the German]:
“I publish with pleasure the following report that my dear colleague and collaborator, Herr Fritz, has made about the periodic appearance of the aurora:
‘The aurora, the light produce by the Earth, has long been known to be a periodic phenomenon in mid-latitudes of the northern hemisphere, as Mairan, Hansteen, Ritter, Muncke, Olmstedt and others have shown in excellent works […]. For this investigation I had before me the some 5800 days with observed aurorae published by Wolf in number V of his report series [I have that data too]. The result of the investigation was so compelling that it seemed worthwhile to compile a catalog, being as comprehensive and as complete as possible. […] The resulting catalog contains ~9500 days with observed aurorae, from at least 40,000 observations.'”

The LOO data in Krivsky by eyeballing is stated in around 50-60% of the cases from 1770-1872.

The exact counts are 2344 LOO and 4175 Total, or 56%
1. If your assumption that the LOO data is adding to the European record why does the Silverman/Krivsky data not diverge greatly before 1850.
I’m not assuming that. I’m saying that the LOO records are not European, but American. They do not diverge because the Krivsky data is dominated by American counts.
2. If your assumption that the LOO data is adding to the European record why does the record between 1850 and 1872 show the Krivsky data much lower than the Silverman New England data.
See above. Because at the end of the Lovering data in the 1850s, LOO found a smaller number of observations than Silverman eventually was able to produce, so Silverman has more data than LOO
(the number of observers is not a strong argument).
It is the only argument, see just above, as Silverman dug up more observations than Loomis had.
3. The Krivsky data between 1872 and 1900 does perhaps look suspect. Angot continues the European record after 1872 (with a fairly high proportion of ocean sightings) that does show a fall after 1872 but also shows a rise after 1880.
That ‘rise’ is hardly of significance, but could be caused by heavier ship traffic after 1880. Ocean sightings would be expected to better approximate the REAL frequency because of no street lights.
Maybe the Krivsky record is incomplete from 1872 to 1900. A graph of the Angot complete data might be helpful.\
Not ‘maybe’. Definitely. I gave you a link to Angot. Be constructive: Go make a graph.

P.S. I have added the Wolf data:

Eventually Fritz almost doubled the size [9500] of his list compared with the Wolf list [5800].

Not ‘maybe’. Definitely. I gave you a link to Angot. Be constructive: Go make a graph.
The Angot record must be used with care. Since 1881 there are a lot of mid-atlantic auroras that were not present before 1880.
For consistency the atlantic data need to be excluded and only the land data should be used from
Spain, Italy, France, England, Holland, Belgium, Germany, Bavaria, Saxony, Austria, Hungary, Russia.
In any case, in 1872 about 100-150 total land auroras are observed as in the Angot record catalog, and these are all from Europe, for what I could see . However , during the following solar maxima in 1882, about 25 auroras are seen on the land. This is more than in the Krivsky record, but in 1882 it is much much less (5 times less) than in the New England catalog.
At the faroes about 15-23 auroras are seen on average betwen 1881-1883
So, there is a clear divergence between Angot and New England, and before 1872 the data refers to European land auroras and correspond to Hermann Fritz’s catalogue and does not appear to be too different from Krivsky record which uses some criteria that would reduce the number of auroras. The other years after 1872 the number of auroras is much less than the New England one, and it appears that the 1875-1890 was generally low compared to previous decades.
Geoff, if you can plot a figure, it would be nice. Just count all land auroras since 1850, You should get something larger than Krivsky record.

First we should exclude ship data from the Fritz/Krivsky catalog you are using.
But there is no reason the exclude the ships. They are perfect ‘rural’ sites in perfect locations. So give closer to the TRUE activity.
In any case, in 1872 about 100-150 total land auroras are observed as in the Angot record catalog, and these are all from Europe, for what I could see
The Angot record is for Europe and Eastern Atlantic.
This is more than in the Krivsky record
The Krivsky record is severely deficient after 1872.
At the faroes about 15-23 auroras are seen on average betwen 1881-1883
The Faroes are abnormal and no good.
The other years after 1872 the number of auroras is much less than the New England one, and it appears that the 1875-1890 was generally low compared to previous decades.
As I said, the Krivsky record is severely deficient
Just count all land auroras since 1850, You should get something larger than Krivsky record.
Since the Krivsky record includes ships, you would be comparing apples and oranges, right?
Anyway, the Argot number for land only for 1882 is 27, Krivsky is 3. For 1881, Arnot has 10, Krivsky 1; for 1885, Arnot has 12, Krivsky 1; for 1884, Arnot has 9, Krivsky has 0, and so on…

November 27, 2011 9:42 pm

Angot record does not contain ship atlantic records before 1881. All auroras before 1881 are from the European mid-latitude cities and land regions and islands such as Malta in the mediterranium .And this criteria needs to be kept after 1881 too for a proper comparison.
Forget Krivsky for now, his cartalog should contain less auroras than Angot because Angot uses all observations, while Krivsky uses as criteria that an aurora needs to be seen in multiple regions, not just in one city.

No, that is not correct. This was only the case for Fritz records. Krivsky uses the LOO records uncritically without any exclusion criteria. And we can hardly forget Krivsky as your paper is based on his catalog.

I would gladly assume with you that every LOO record was just a confirmation of an unknown European record, because that would mean a complete mix. Are you ready to agree with that?
The Krivsky documentation suggests exactly that. The European records are unknown because Krivsky only used the confirming record in his database. So I completely agree but that means the American records are only used to confirm Euro records which means no bias from the American records.
No, it says “If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned”. No other records than Fritz’s.
I guess it depends on the use of the word “particularly” I read it as in particular as in the most obvious but you could also use the word to mean “only”. He does mention all authors of partial catalogues or sets of observations that fall into the need of confirmation data.
Since phenomena which may but need not have been aurorae were described in the
past centuries, the authors of catalogues must have considerable experience to
be able to distinguish, on the basis of the description, whether a fireball,
meteoric shower, noctilucent clouds, twilight phenomena, etc., had not been
mistaken for an aurora. That is why authors of this catalogue did not adopt
all the occurrences of aurorae, given by the authors of the partial catalogues
or sets of their observations. This applies particularly to H. Fritz’s
catalogue [2], which evidently, as already discussed earlier also by other
authors, contains erroneous records of phenomena other than aurorae especially
in the past three centuries.
We seem to have no verification of the actual LOO data. In his book he states many areas of reference for aurora.
——————————
Yes, he used the others to verify that the New England aurorae in his catalog [mostly drawn from Lovering] behave just like the European records.

This is not really good enough, there are inconsistencies, would much prefer to see the actual Loomis data.
1. If your assumption that the LOO data is adding to the European record why does the Silverman/Krivsky data not diverge greatly before 1850.
————————
I’m not assuming that. I’m saying that the LOO records are not European, but American. They do not diverge because the Krivsky data is dominated by American counts.

So you are saying without the LOO records the Krivsky data would be much lower than the New England data before 1850. We could test that in a rough fashion by plotting the Fritz data against the New England data before 1850.
2. If your assumption that the LOO data is adding to the European record why does the record between 1850 and 1872 show the Krivsky data much lower than the Silverman New England data.
—————————————
See above. Because at the end of the Lovering data in the 1850s, LOO found a smaller number of observations than Silverman eventually was able to produce, so Silverman has more data than LOO.

Without the original Loomis data that might be hard to prove. But in any event if the LOO data was added to the older Krivsky data it should outweigh the New England data. This is a crucial point that is showing your assumption to be incorrect.
I will plot the Angot data using only land sightings as I agree with Nicola. Fritz used very few oceanic records.

November 28, 2011 2:21 am

The Angot data once the ocean data was ignored does not deviate greatly from the Krivsky record. I counted each month in their own bucket to hopefully avoid as many errors as possible. Of note was that there were very few days where an ocean record backed up a land record. I think Nicola is right to avoid the ocean data. Some days post 1873 have many different land locations listed so the pool looks generous.

No, the Krivsky text does not say that. But you then suggest that the Krivsky record is a perfect mix of European and American records, so that it is NOT a pure European record as you maintained earlier. But see below.
So you are saying without the LOO records the Krivsky data would be much lower than the New England data before 1850. We could test that in a rough fashion by plotting the Fritz data against the New England data before 1850.
http://www.leif.org/research/Fritz-vs-New-England-1830-1850.png shows just that.
The Fritz data includes every entry [even for one station only – since you are assuming that they are validated somehow from unknown data…]. The Fritz data is 41% of the total Krivsky list, thus showing [again] that that the Krivsky list is dominated by American data.
Without the original Loomis data that might be hard to prove. But in any event if the LOO data was added to the older Krivsky data it should outweigh the New England data. This is a crucial point that is showing your assumption to be incorrect.
If this is crucial it works both ways. There are 522 original Fritz entries [in 1830-1850]. 153 of those are self-validated because they are based on more than one station. So, the older Krivsky list would have had between 153 and 522 Fritz data. There are 898 LOO data so the result of adding the older Krivsky list to the LOO data would yield a number between 1051 and 1420. There are 1274 New England entries, so you can see that most of the entries in the combined list are just the LOO [New England] data. The smattering of other catalogs included for that time is so small as to be negligible. So, this crucial point shows that the Krivsky list is totally dominated by American data.
I think Nicola is right to avoid the ocean data.
That is just confirmation bias. I think we should defer to the experts at the time [Angot, Fritz] who compiled the lists. If they thought the ship data were good, so should we, unless we have evidence of the contrary.

November 28, 2011 10:24 am

Leif, sorry
Angot does not contain a single mid-atlantic aurora before 1881.
You bias the record if you just add those ocean auroras to a record that until 1881 uses only and exclusively land European auroras.
Moreover, do you know that when in the mid-Atlantic it is night, in half Europe is already day and viceversa? You know that the Earth is not flat and it is spinning, don’t you?
By the way, Angot record from European land only as shown by Geoff from 1872 to 1890 confirms the Faroes record from 1872 to 1890.

Moreover, do you know that when in the mid-Atlantic it is night, in half Europe is already day and viceversa? You know that the Earth is not flat and it is spinning, don’t you?
First of all, those records are not ‘mid-Atlantic’ but East-Atlantic. Europe stretches [by you own admission from Portugal to Russia, spanning more hours of time difference than to the east-Atlantic. Perhaps you didn’t know that, but now you know.
By the way, Angot record from European land only as shown by Geoff from 1872 to 1890 confirms the Faroes record from 1872 to 1890.
It is the Faroes record from 1890 on that is wrongly calibrated, so this is irrelevant. And, BTW, what difference does it make if the aurorae is observed from a ship or from a small island?

A clue to the record may be that the observer changed in 1925 [red line], from located in Thorshavn to located in Hoyvik. http://www.leif.org/research/Faroes-Aurorae.png
The variation is likely correct outside the blue box as it there matches what is observed elsewhere [such as Denmark and New England which are much more mid-latitude than the Faroes’s 62N]

Come to think about it, all Faroes yearly counts must be multiplied [for comparisons] by ~1.6 as they cannot see the aurorae during the summer [roughly May through August] on account of their high latitude. This goes for Iceland and Greenland data too, but with an even larger factor.

November 28, 2011 4:40 pm

Leif, do not change the topic.
We are discussing the period 1872 to 1890.
If, as you say, the Faroes auroras are correct before 1890, then they match my claim and agree with Angot european record (even better with the 1.6 amplification factor). The ocean Auroras were not taken close to Faroes, but in the Atlantic between England and New England. Those were ships that moved between England and north US and Canada.
Angot contains extremely few ocean records beforee 1881. They do not change anything.
Were people in Thorshavn always drunk to see so many imaginary auroras there betwen 1890-1925? or were the people in Hoyvik always sleeping after 1925 to see so few auroras?

The topic is the flaws in your paper; that has not changed at all. In fact, those flaws are becoming increasingly evident.
If, as you say, the Faroes auroras are correct before 1890, then they match my claim and agree with Angot european record (even better with the 1.6 amplification factor).
Since they match all our claims, that does not mean anything. The abnormal bit is 1891-1925.
The ocean Auroras were not taken close to Faroes,
Of course not, as the Faroes are at much too high latitude. That data should not be used by anybody nor by you. As they are not mid-latitude. Using them is one of the major flaws in your paper.
but in the Atlantic between England and New England. Those were ships that moved between England and north US and Canada.
As you can see here, the ships moved close to the 5/yr isochasm http://www.leif.org/research/Angot-Ship-Aurorae-1881-1890.png ; each blue circle is a ship observation. The red squares show varies cities in New England and Europe. The red slanting rectangle contains observations that were take at too high latitude relative to the isochasm. Those should properly not be used. The same goes for the red square marked with a red cross [the Faroes]. Angot was not a moron [as you indirectly suggest] but knew what he was doing. Those ships were perfect platforms for auroral observations at a time where interest was decreasing in mid Europe. Leading up to, during, and some time after the First Polar Years 1881-1884 ships were encouraged to report auroral sightings and Angot made good use of them as you can see. A great aurorae can be observed equally well on land, on a small island, or at sea, and even from space http://www.youtube.com/watch?v=viH18XvTTYw . In fact most of the Danish observations were made from ‘weather-ships’ [remember Denmark is a nation of 500 islands] that were preferred because of the low artificial light level and an unobstructed view of the horizon. So ship observations are great and should not be excluded. If there is a great aurora in the sky you’ll see it from land or from sea equally well.
Were people in Thorshavn always drunk to see so many imaginary auroras there betwen 1890-1925? or were the people in Hoyvik always sleeping after 1925 to see so few auroras?
You don’t seem to know much about observers. They vary greatly in ability and perseverance. Some will look only once a night [especially in winter where it is cold and nasty and their main job is to keep track of other things]. Others are very keen and look several times each night. So there is great opportunity for observer-dependent bias.

That region is like Denmark! On the upper borther of the isochasm.
And they match excatly the New England region, just above the Mid-European upper borther isochasm, as I said.

Leif, am I wrong or most of those ship records are just above the isochasm that corresponds to the Mid-latitude Auroras? That region is like Denmark! On the upper border of the isochasm.
So? Denmark has the same shape variation as a few hundred km south. Apparently, you think that the Faroes are within the mid-latitudes, since you use them…splice them to what you think is mid-latitudes in Fig. 2B. This is a severe flaw, as I have pointed out several times. Speaking about the Faroes and their [assumed] drunken observers, it is probably more likely that the 1900-1925 data is correct and it is the data outside of this interval that are too small. This is because the Faroes lie on a high isochasm [=60 or so]. Either way, the three intervals have different counting properties, making the Faroes unreliable. But you should use the data even if they were reliable as they refer to an area far too north.
What are those red boxes on the right? Are they the data from England?
As I said: “The red squares show varies cities in New England and Europe.” You can read?
Don’t you see that they are below the Mid-European upper border isochasm?
They are various cities: London, Paris, Berlin, Frankfurt, etc And the ones on the continent are indeed below the 5/yr isochasm. Indeed, they are closer to the 1/yr line. This is further proof that the Krivsky catalog is dominated by New England data. For the ~100 years 1770-1872 where we have reasonable data the average number of aurorae per year is 42. Since mid-latitude continental Europe lies below the 5/yr isochasm, we should expect at most 5 aurorae per year, yet we have 42, which is closer to the isochasm for North America [which as you can see lies above the 5/yr line]. The ships are also above, so corresponds well to the New England data. There are 171 ship observations over 10 years, for an average of 17/yr
The point is that the Krivsky catalog is completely dominated by North American data. The mid-latitude continental European region where the isochasm is between 5/yr and 1/yr, cannot supply the 5300 auroral days in the list. That would take several thousand years. This I have pointed out several times, but you have displayed a reading deficiency, so clearly it was necessary to say it again. Pleasure acknowledge that you have 1) read this, and 2) understood this.
But it doesn’t matter if the catalog you use is dominated by North America; because the North American and European counts differ only by a constant factor [of perhaps 5] and the variation over time is [to this factor] the same. In a very real sense this whole, long discussion has all been for naught as there is no qualitative differences between regions sufficiently far from the auroral zone.

The point is that the Krivsky catalog is completely dominated by North American data. .
This is still your opinion and unfortunately it looks like none of us can prove it either way. The important factor is that the baseline Fritz record has the same trends as the Krivsky data (who would have thought?), and the trends are what is important to Nicola’s paper.
They are various cities: London, Paris, Berlin, Frankfurt, etc And the ones on the continent are indeed below the 5/yr isochasm. Indeed, they are closer to the 1/yr line.
And yet the original Fritz record records 179 aurora for 1872 (with Angot’s data to complete the year.) This from a pure European data set.
In a very real sense this whole, long discussion has all been for naught as there is no qualitative differences between regions sufficiently far from the auroral zone.
There is good reason to stay within a region, all is not known about aurora. The data after 1850 is a good example of the divergence in the two regions.

I would say that the data is conclusive that Krivsky is dominated by American records. I don’t know what you mean by ‘trends’. Here is the standard meaning http://en.wikipedia.org/wiki/Trend_estimation
If you simply mean the variation up and down with time, then since all regions away from the auroral zone respond to the same input [the solar wind] they should show the same general variation. So one would expect that Fritz [being just a subset of Krivsky] should show the same variation as Krivsky, but at a more subdued level, corresponding to the somewhat lower geomagnetic latitude and isochasm level. This is clearly shown in the ‘crucial test’ you proposed http://www.leif.org/research/Fritz-vs-New-England-1830-1850.png it is curious [but predictable] that when the ‘crucial test’ doesn’t come out the way you want, it is no longer ‘crucial’.
And yet the original Fritz record records 179 aurora for 1872 (with Angot’s data to complete the year.) This from a pure European data set.
And 1879 has no aurorae at all. You cannot use just a single year as an example as the number of days with aurorae varies strongly with the sunspot cycle. The isochasms are a statistical mean over decades or centuries. BTW, Chapman [Annual Reviews, vol 8, 1970] remarks “Vestine (1944) corrected Fritz’s isochasms near the auroral zone, but the outer isochasms have never been revised, though they are based on rather scanty data, accumulated unsystematically over the centuries”.
There is good reason to stay within a region, all is not known about aurora. The data after 1850 is a good example of the divergence in the two regions.
First: yes all is known as far as this discussion is concerned. That you don’t know this, is something that can be rectified, and which I have worked hard to do. Second: The divergence is due to different observers and compilers, as I have shown. Third: Krivsky mixes regions anyway.

“The point is that the Krivsky catalog is completely dominated by North American data.”
This is still your opinion and unfortunately it looks like none of us can prove it either way.

Krivsky does not claim that this is a European Catalog [as you do]. In fact he says about the final list:
WORLD LIST OF POLAR AURORAE < 55 AND THEIR SECULAR VARIATIONS

I would say that the data is conclusive that Krivsky is dominated by American records. I don’t know what you mean by ‘trends’. Here is the standard meaning http://en.wikipedia.org/wiki/Trend_estimation
If you simply mean the variation up and down with time, then since all regions away from the auroral zone respond to the same input [the solar wind] they should show the same general variation. So one would expect that Fritz [being just a subset of Krivsky] should show the same variation as Krivsky, but at a more subdued level, corresponding to the somewhat lower geomagnetic latitude and isochasm level
.
You can huff and puff as much as you like but the data does not lie. If you mean the Krivsky data is being dominated by the Amercian record (as in has more entries from America that are not verified by European records ie single American records which goes against Krivsky’s guidelines) then the Krivsky data should align with the Silverman New England record which it clearly is not even close after 1850. The dramatic change and difference after 1870 a great example ie the Krivsky record falls to nothing while New England record continues to show significant aurora. This you have no reasonable argument for but no doubt you will come back with something because you REFUSE to admit when you are wrong. I don’t see any point in continuing the conversation, we are going in circles.
You have been shown by many authors that:
The mid latitude aurora do not follow the sunspot cycle.
There is a 60 year period in the mid latitude aurora.
The Nth American (New England) and European zones (>55 deg) display different aurora trends and are not compatible.
Mid latitude European aurora at >55 deg can occur at less than 7 Kp.
Mid latitude European aurora at >55 deg can occur at low Kp without a geomagnetic storm the previous day.

They align nicely up mid 1850s. After that Krivsky is missing a lot of records that Silverman has.
The dramatic change and difference after 1870 a great example ie the Krivsky record falls to nothing while New England record continues to show significant aurora.
Just shows how poor the Krivsky data is.
The mid latitude aurora do not follow the sunspot cycle.
On the contrary every scientist who has studied this agree that there is a strong solar cycle dependence. E.g. Siscoe RG018i003p00647: “Lovering demonstrated the close similarity between auroral variations recorded in Europe and in America. Fritz and Loomis separately established that the variation of the aurorae conform closely to variations in solar spottedness”. Learn more: http://www.leif.org/EOS/Chapman-Auroral-Physics.pdf [from 1970, but fully confirmed by all modern data].
There is a 60 year period in the mid latitude aurora.
In a subset of the data you can find anything you like especially if you splice in cherry-picked, dubious records from way too high latitude. Over the full time span, that ‘cycle’ dwindles to noise.
The Noth American (New England) and European zones (>55 deg) display different aurora trends and are not compatible.
Siscoe RG018i003p00647: “Lovering demonstrated the close similarity between auroral variations recorded in Europe and in America”
Mid latitude European aurora at >55 deg can occur at less than 7 Kp.
It takes Kp=7 to generate an aurora that is seen over a large area. Because aurorae can be seen 1000 km away, you might see some near the horizon at lower Kp.
Mid latitude European aurora at >55 deg can occur at low Kp without a geomagnetic storm the previous day.
If so, they are very rare. A geomagnetic storm last several days and energy is stored in the magnetotail and can be released at any time within or even shortly after the storm. All this has been known for a century.
I don’t see any point in continuing the conversation
You are late with that realization, but I accept your throwing in the towel.

Just shows again how poor the Krivsky data is after he ran out of Fritz data. For 1873 Krivsky has but three records, while the European non-ship Angot record has 20 days with multiple aurorae [thus self-validating according to Krivsky]. In 1874, Krivsky had 3 records, while the European non-ship Angot record has 8 days with multiple aurorae [thus self-validating according to Krivsky]. And so on. What you call ‘trends’ are due to differences between the catalogs and number of observers.

Another example why discussion is pointless. Both the Krivsky and Angot record are bumping along the bottom while the New England record is around 100.

The New England record was carefully maintained by observatories and dedicated individuals [like Benton]. In Denmark, we were keeping accurate records too, matching New Englands: http://www.leif.org/research/Denmark-Vermont-Aurorae.png
Fritz’s record is also ‘bumping along the bottom’ http://www.leif.org/research/Fritz-vs-New-England-1830-1850.png This is as we would expect because the isochasms for mid-latitude Europe is an order of magnitude smaller than for Denmark and for New England. Nothing mysterious or hard to understand here. Your mistake is to assume that every LOO is covering a Fritz record. I showed that was not the case, again http://www.leif.org/research/Fritz-vs-New-England-1830-1850.png .

In essence Fritz as there are very few other ones.

Since the LOO data only really starts in 1776, that should be the start. Anyway, the 1253 records 1830-1850 is a very good sample of the 2829 records 1776-1850, so yes that is a crucial test.

I consulted my medium in Berkeley who got the original data from Krivsky. Here is a comparison:
http://www.leif.org/research/Krivsky-1831.png showing that the LOO records were simply added to the old list and did not cover any Fritz or other European record, not a single one. Other years show the same. So, the LOO records [from America] inflate 1831 from 21 original European [and American] records recorded by Fritz to 56 records. That is: the final list is dominated by American records and is not a pure European record. That puts the discussion to rest.

Actually your medium has made things rather difficult for you. Of the new LOO records on the revised Krivsky list there are 10 corresponding Fritz entries that are singletons that were not able to be used in the first list because there was no verifying record. So this proves the LOO record is just a qualifier. The remaining LOO records that don’t correspond with a Fritz record are obliviously covering single records that appear in the other 35 odd European lists that Krivsky used. Did you ever wonder why there is not a lot of the non Fritz Euro data in the Krivsky list?…simple answer, they needed to be verified.
Keep trying Leif, you will have to do better. Perhaps your medium can find Krivsky’s original work sheets?

You are beginning to sound like Baghdad Bob, http://politicalhumor.about.com/library/jokes/bljoke-iraqinfominister.htm
There were only 5 non-Fritz entries in the Krivsky list, from 3 other lists. The simple answer is that there are no other. BTW, Krivsky also comment on the sudden drop after 1872 and why there are so few records in the list after that: “In an attempt to preserve homogeneity, the aurorae observed towards the end of the whole period, including those from the southern mid-latitudes, were not taken into account”
The data from NOAA that is ‘the final list’ starts out with a note from the editor:
ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/AURORAE/aurorae.dat.rev

Since aurorae that are active enough to be seen below 55N are typically global, it is very likely that the same aurora will be seen both in New England and in Europe. That does not mean that the LOO records are covering entries in the original catalog, they are not coinciding with a single one. In fact, there are, as you point out, still a further 35 LOOs that do not coincide with any other record. Krivsky did not compose the final list, “EDITOR’S NOTES: The digitization of these data were part of a data rescue project funded by the NOAA Earth Systems Data and Information Management (ESDIM) program and the NASA Space Physics Data System (SPDS) Data Set Preservation and Supply program (NASA 01026). Data were key entered using ESDIM funds and processed and quality controlled using NASA SPDS funds.” and “A supplemental list of data found in “Supplement of the Catalogue of Polar Aurorae <55N in the Period 1000-

Take another example: November, 1834:
1834 11 2 LOO
1834 11 03 F
1834 11 5 LOO
1834 11 6 LOO
1834 11 28 LOO
Fritz’s list has only one [and it is a singleton] entry in November, 1834, on Nov. 3 and only observed in England. The case is clear.
And while you are at it perhaps apologize to the scientists you have maligned in this thread.

Of the 2344 LOO records between 1776 and 1872, not a single one replaces any of the 1482 F records in the original 1988 Krivsky list, although, as you and Nicola, so strenuously have maintained “If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned”. But no LOO has ever replaced an F. It is impossible that over ~100 years, it never happened that a LOO record happened on a day that was already validated as an F day. The case, again, is clear.

It is quite amazing what lengths you will go to in an attempt to save face.

Instead you continue with another incorrect statement That does not mean that the LOO records are covering entries in the original catalog, they are not coinciding with a single one
The LOO records in your data provided coincide with 9 Fritz singleton entries that did not make the first list. Is this so hard to conceptualize? Check the Angot record for yourself and come back to me. You can apologize then.
In fact, there are, as you point out, still a further 35 LOOs that do not coincide with any other record
You are all over the place…I said 35 odd European lists (authors) that Krisvksy used. There are 34 LOO entries in your example. There are 9 (I counted one incorrectly) Fritz singleton records that occur on the same day as the LOO entry that were not in the original Krivsky list. So for 9 out of 34 LOO entries we have undeniable proof of Krivsky’s method of confirming Euro records with American records. The rest you will have to contact your medium for. (they will reside in the remaining 35 euro lists)
Krivsky did not compose the final list,
I am very aware of who put together the final list. The Supplementary list is constructed by Krivsky using his rules. So any supplementary record has already had the verification process applied, all NOAA did was add them together. Krivsky talks about this process in his notes. Do you really think Krivsky who was a life long professional would change his method of verification on part two of his project? He is one of the scientists you owe an apology to, the referees to Nicola’s paper are others. All this based on an unproven assumption…shame, shame.

really!
LOO and Fritz were not the only catalogs used, there were others.
The fact that there was an attempt to verify and validate the records with at least two entries is proved by comparing other data in 1834
1834 1 5 LOO Jan. -5, Catterick Bridge (Yorkshire).

where the European record on the right is taken from Fritz.
Note that in Fritz it is listed only one city! So the data needed a validation which was given by LOO.

Does not show. Perhaps you state who you are aware of.
The Supplementary list is constructed by Krivsky using his rules.
This is an unfounded speculation. Krivsky himself states that the LOO entries are predominantly North American.
Do you really think Krivsky who was a life long professional would change his method of verification on part two of his project?
I do not think the supplement was verified, simply because there are not enough other records out there to do that.
He is one of the scientists you owe an apology to
He is not responsible for your mistakes or Nicola’s misuse of the data.
the referees to Nicola’s paper are others.
Not doing due diligence on the Krivsky list and its provenance is bad enough, but letting slip by the splicing together of dominantly New England data and near Auroral Zone Faroes data and calling the whole thing mid-latitude European data is unpardonable. Showing either sloppiness
or core incompetence. Neither deserves any favorable consideration.

No, I don’t think the LOO records are confirming any records at all. Loomis was dead long before Krivsky was born, so did not know about Krivsky’s method [which BTW is not always applied]. The LOO list is what Loomis reported back in the 1870s.

December 1, 2011 7:29 pm

Leif, do not be so naive!
There are a lot of LOO data that are present in the european record of Fritz.
The fact that not all LOO data are present in Fritz was because many other minor catalogs were used as well. It is evident that you need to cross -compare all catalogs to undrstand what Krivsky did.

There are many, many more LOO records than singleton Fritz records. Try your hand on 1844 which has 25 LOO records and 9 Fritz singletons. Even you should be able to understand that.
I am wondering how it is going to take before the penny drops. Let us take it slow, one point at a time.
If you are looking at the Krivsky list there are 8 Fritz entries for 1844. They are not singletons, they are verified Fritz entries probably? from the first list. Only 1 of the 8 has a verifying record within Fritz’s list, so to make the Krivsky list another Euro record must exist, but is hidden because of Krivsky’s method. A singleton in my book is a Fritz entry that does not make either of Krivsky’s lists. If you look at the Fritz (Angot) data you will see a very large proportion of days where only one town or country is listed. This is a singleton if not verified by another record from Europe of America. Later when the Loomis data was used some of these singletons are now added to the 2nd list but have a LOO label on them according to the Krivsky method. Other singleton (non verified records) from the other 35 odd Euro data sets are also dealt with in the same way.
Your earlier state if correct Of the 2344 LOO records between 1776 and 1872, not a single one replaces any of the 1482 F records in the original 1988 Krivsky list, is proof that the LOO records are confirming singletons left over from the old list along with new singletons available in the later Euro data.

Only 1 of the 8 has a verifying record within Fritz’s list, so to make the Krivsky list another Euro record must exist, but is hidden because of Krivsky’s method.
You have this completely backwards. Fritz’s full list [not just the European subset Angot gives] included a lot of aurorae from region IV [America], so these 7 have a matching aurora from region IV if they are not on the region II list [Angot’s], region I has so few that it doesn’t matter. So, again the list shows that the Original list is not a European list, in fact, dominantly an American list when you add the 25 LOO records from North America..
Your earlier state if correct Of the 2344 LOO records between 1776 and 1872, not a single one replaces any of the 1482 F records in the original 1988 Krivsky list, is proof that the LOO records are confirming singletons left over from the old list along with new singletons available in the later Euro data.
There are very few new Euro data and they are after 1872 [SC2]. The LOO record is, as Krivsky tells us, predominantly American data.

for the year 1834, that you like so much, it has 5 auroras each for month from Aug to Dec. However Fritz does not have auroras in Aug and Oct. So, there are two additional auroras which may match two auroras used in LOO.
Ann we can continue for the other ones

Not a single one has been replaced by a LOO entry, so they must be verified by an region IV [North American] entry, making that 7+25=32 American entries vs. only 1 (Dec 29th) verified pure European entry. So, again, the Krivsky list is overwhelming an American list.

There are no singletons in the first list, they were all verified [most by region IV data]. The final list is identical to the 1988 [first list] except for the LOO [and the smattering of SC2 entries]. Doesn’t it strike you that not a single LOO entry matches ANY of the entries in the 1988 list? The reason is [I think] that Krivsky didn’t want to count an auroral day twice [although he actually did on exactly one occasion]. What is important is that according to Krivsky’s own recipe, if a LOO were confirming an F entry, then the F would have been overwritten by the LOO, and there is not a single case of that. I think that the people at NOAA that added the LOO data also did not want to enter the same day twice, so they removed LOO records such as to ensure that they didn’t get any duplicates [and missed one: 1850 2 3].

Weak response. When will you supply some substance?

—————————-
You are forgetting I have the first list from 1988.

So, again, the Krivsky list is overwhelming an American list.

You are still not getting it. You would not expect a LOO entry to replace a Fritz entry from the 1st list. The LOO entries are verifying Euro singletons (non verified) that were left off the first list or verifying the newer Euro entries on the 2nd list. Each list in its own right has to have a verification. NO single records as in 1 aurora seen in only 1 place on the same day are allowed. Every LOO record has a corresponding Euro record behind it. Krivsky clearly points out that only aurora from regions I and II are considered as the initiating records.
The 2nd list is a supplementary list, it is extras found outside of the first list. Then the two are added together. The fact that you cannot find one LOO entry over riding a Fritz entry from the first list is proof of this. You need to acknowledge you understand this point.

The LOO entries are verifying Euro singletons (non verified) that were left off the first list or verifying the newer Euro entries on the 2nd list.
Since there are many more LOO entries than Euro singletons [as per Angot] and almost no Euro entries on the 2nd list [as per Krivsky “predominantly American”], you should be able to see that what you claim doesn’t add up. There are no ‘extras’ found outside the 1st list. The other catalogs as I showed Nicola don’t count as they almost all refer to times outside the LOO data [1776-1872].

There are no singletons in the first list, they were all verified [most by region IV data]
.
Of course there were no singletons in the first list. They cant make it if they are singletons. You also do not know how the Fritz entries that only have one sighting in region I or II are verified, you are guessing, they could be verified by other Euro lists.
The final list is identical to the 1988 [first list] except for the LOO [and the smattering of SC2 entries]. Doesn’t it strike you that not a single LOO entry matches ANY of the entries in the 1988 list?
Of course there are no conflicts, Krivsky did the sorting correctly. Singletons left over from the first list become available for a Loomis verification.
if a LOO were confirming an F entry, then the F would have been overwritten by the LOO, and there is not a single case of that.
Right here is where you lose the plot. The F entries on the first list are already confirmed, so LOO is not needed (they may exist). The LOO entries on the 2nd list are verifying left over Euro singletons.
I think that the people at NOAA that added the LOO data also did not want to enter the same day twice, so they removed LOO records such as to ensure that they didn’t get any duplicates [and missed one: 1850 2 3].
Very big assumption. You are saying Krivsky just dumped the LOO records directly into the 2nd list. This goes against all his principles and guidelines that are clearly laid out. NOAA did not add the LOO data, they merged the two records with Krivsky’s approval. They use the word “combined” Krivsky states in his supplement area:
“The supplement contains corrections and new data of the past observation of
north polar aurorae (<55 degrees)."
Corrections and new data so he has built the supplement with the original database in mind. Why would he trash the original database as you have suggested.

how the Fritz entries that only have one sighting in region I or II are verified, you are guessing, they could be verified by other Euro lists.
No, Krivsky says explicitly: “auroral data were adopted provided there was guarantee that they were simultaneously observed in a larger geographical region. i.e. provided they were recorded at a number of stations in Region I or II (i.e. Europe), or in Region I or II and at the same time in Region IV (i.e. America). Fritz’s [2] division into regions is as follows: I – south of 46,
II – between 46 and 55 , III – from 55 to the polar circle, IV – America south of 60 , V – high latitudes. If the source of an auroral observation given by H. Fritz [2] was also given by another author, the latter has been mentioned.”
Forget region I as there are so few aurorae from there. So, the criteria were: 1) multiple stations in II or 2) at the same time an aurora in II and IV. Not by other Euro lists, except the fewer that ‘were also given by another author’. [349 vs. 1482 by Fritz]
Singletons left over from the first list become available for a Loomis verification.
LOO data were predominantly American
Right here is where you lose the plot. The F entries on the first list are already confirmed, so LOO is not needed (they may exist). The LOO entries on the 2nd list are verifying left over Euro singletons.
1st: the LOO are predominantly American. 2nd: No, there are many more LOO than euro singletons.
You are saying Krivsky just dumped the LOO records directly into the 2nd list.
The second list is just the LOO records. ‘Dumped’ is a silly word. Scientists don’t ‘dump’ data.
This goes against all his principles and guidelines that are clearly laid out.
Big assumption. And there are simply not enough other Euro records for that.
NOAA did not add the LOO data, they merged the two records with Krivsky’s approval.
Assumption.
They use the word “combined”
means “merged”
Krivsky states in his supplement area:
“The supplement contains corrections and new data of the past observation of
north polar aurorae (<55 degrees)."

You left out the important bit: “New data are based predominantly on the two Catalogues, i.e. of Loomis (LOO) and of Schroder (SC2). In the Catalogue LOO are collected the aurorae which were observed in North America.”
Corrections and new data so he has built the supplement with the original database in mind.
No, he notes that the list was a World List of Polar Aurorae < 55N. Not a European list.
Why would he trash the original database as you have suggested.
He didn’t trash the original database. NOAA did, if anybody did. NOAA removed duplicates from the too list, when they were merged.

Which catalog did all the ‘Euro’ singletons that are supposed to sit under every LOO entry come from? Same with all other years. There are not enough ‘other’ Euro records out there. You are suggesting that Fritz did a poor job, while everybody else praises him for his outstanding thoroughness.

The LOO entries are verifying Euro singletons (non verified) that were left off the first list or verifying the newer Euro entries on the 2nd list.
————————————–
Since there are many more LOO entries than Euro singletons

Your example of 1831 shows 9 new Fritz singletons out of 34 LOO records. We have no idea how many non Fritz Euro singletons were at Krivsky’s disposal. You left out the papers that he could use during that time period, and it only takes one to fill in the blanks. Do you know how many Fritz singletons are available during the Loomis time frame?

If one eliminates from your and Nicola’s list of 35 catalogs the ones that are not applicable, one is left with these four:
L3 LINK
Mo MOSSMAN
R RETHLY A., BERKES Z.
S SEYDL O
The Seydl catalog has two entries for 1831 [none corresponding to a LOO record] and no entries for 1834, so we can cross that one out.
This leaves
L3 LINK
Mo MOSSMAN
R RETHLY A., BERKES Z.
There are no L3 or R records mentioned in the Supplement [which the medium has produced] and only one Mo record. For them to supply a thousand+ singletons is not credible.
Do you know how many Fritz singletons are available during the Loomis time frame?
This is your only remaining straw. You must mean non-euro singletons as we both know the euro ones. The Fritz 1873 book is on its way to me, so we shall see.

Furthermore Krivsky has this to say about Seydl: “By analysing Seydl’s catalog of aurorae we arrived at the conclusion that the number of 402 aurorae published in the catalog is relatively small and clearly does not correspond to reality”. So not the source of the thousand+ you need.

NOAA stated that they simply typed in the data and merged them into one list. In the text for the 1996 supplement http://www.leif.org/EOS/Krivsky-Supplement.pdf Krivsky notes about the new data: “Only new data sources with abbreviations are referred”. This means that if there were already an entry in the first catalog, there would not be an entry for that in the Supplement. This explains where there is no overlap [except on one day 1850 2 3] between the two lists.
Geoff Sharp says:
December 1, 2011 at 10:28 pm
Corrections and new data so he has built the supplement with the original database in mind. Why would he trash the original database as you have suggested.
“He didn’t trash the original database. NOAA did, if anybody did. NOAA removed duplicates from the two lists, when they were merged.”
Now that we have the actual text of the supplement we can see that nobody trashed the data [so NOAA did not remove duplicates because there weren’t any], and as you, rightly, surmised Krivsky built the supplement with the original database in mind namely by not including a new entry if there was already an old entry for the day.
It does help to actually get the original sources. So, again, no mysterious ‘extra’ Euro entries from unknown and unnamed hidden catalogs. Result: the final list is completely dominated by North American data and is in no way, shape, and form a European list.

Unfortunately the actual paper does not really give us any more information other than verifying the amount of original LOO entries which we already had as it turns out. I don’t think NOAA has trashed the data at all, unless the two sets were not meant to be merged, but Krivsky was aware of the whole process and devised the supplement to fit in with the original data. But the question still remains how Krivsky added the LOO records. Your dismissal of the European data is way too early, I don’t think you have done a thorough examination and have left out the Russian and Asian data etc…more work to do. I am waiting to here back from a NOAA retiree who may have some more info hopefully.

It is difficult to intelligently discuss the observations (glacial/interglacial cycle, the solar cycles, and the sub climatic cycles) without an outline of the basic mechanisms. The next few comments provides observational evidence in links to papers from different specialty fields to provide an overview and explanation as to how the mechanisms work.
The paleoclimatic record shows evidence of cyclic changes in the climate (Heinrich events, Bond events, and so on. Named after the paleoclimatic researchers that found the climate events.). It has been known for some time that there is concurrent with the past climate change events abrupt changes of cosmogenic isotopes that are deposited on the ice sheets and in sediment on the ocean floor. The cosmogenic isotopes are formed by high speed galactic particles referred to as galactic cosmic rays GCR (mostly protons) that strike the earth’s atmosphere. The strength and extent of the solar heliosphere and the strength of the geomagnetic field both affect the intensity and the statistical velocity/energy distribution of the particles that strike the earth’s atmosphere.
Specialists in the study of the geomagnetic field have found something external (As will be shown by observational evidence the ultimate cause of the geomagnetic field changes is the restarting of the solar magnetic cycle after interruption.) is periodically abruptly changing the inclination the geomagnetic field and the strength of the geomagnetic field. The geomagnetic field changes are too rapid and too large to have been caused by any geophysical process. (The earth’s core cannot suddenly change to causes the observed change.)
The largest events geomagnetic excursions (the non polar component of the geomagnetic field suddenly increases at the geomagnetic excursions and the strength of the geomagnetic field is reduced by a factor of 7 to 10) occur at the glacial/interglacial climate change transitions.
Comment: The geomagnetic field intensity is stronger during the interglacial period.
There are smaller versions of the forcing event that causes the geomagnetic excursions. These are called archeomagnetic jerks (The term archeomagnetic jerk is confused by all with the term geomagnetic jerk which is small and rapid change in the geomagnetic field). During archeomagnetic jerk the inclination of the geomagnetic field abruptly changes 10 to 15 degrees and there is 10 to 20% change in the geomagnetic field intensity.
The geomagnetic specialists took roughly 15 years to agree that there were cyclic archeomagnetic jerks and geomagnetic excursions and that the timing of the archeomagnetic jerks and geomagnetic excursions correlate with the abrupt climate changes. The underlying problem with accepting that the geomagnetic field can suddenly be forced is that the forcing mechanism cannot possibly be geological.
If anyone is interested I can explain in some detail how the different proxy data has analyzed and the technical problems associated with that analysis to explain why it took 15 years to get agreement among the geomagnetic field specialists concerning the existence and timing the archeomagnetic jerks and geomagnetic excursions.
Comment: The term archeomagnetic jerk has selected as a key proxy source to determine the inclination and strength of the geomagnetic field is to study kiln fired pottery (sun dials and fired tiles.) The term archeomagnetic is apt as it is necessary to locate the site of the kiln usign archeo analysis. The hot pottery captures the inclination and strength of the geomagnetic field when it cools. The French have a vast collection of small pottery pieces (such as fired floor tiles and sun dials. The fired tiles and sundials are marked with the name of the manufacturer.) which have been gathered specifically for paleo analysis of the geomagnetic field.

But the question still remains how Krivsky added the LOO records.
Krivsky explains that clearly enough.
Your dismissal of the European data is way too early, I don’t think you have done a thorough examination and have left out the Russian and Asian data etc…more work to do.
I’m not dismissing European data. Simply pointing out that after examining the catalogs that Krivsky used [and that he told us about] it is evident that there are no more European data that he could have used, unless you postulate that he had thousands of reports that he is not telling us about. On what do you base “I don’t think you have done a thorough examination”?. I have examined every single report in the catalogs. And there are no Russian or Asian data in any of the catalogs listed by Krivsky for the period in question, with the exception of Fritz [and those would already be in the 1st list]. For example, the K-catalog listed by Krivsky: K KEIMATSU MITSUO: A Chronology of Aurorae and Sunspots Observed in China, Korea and Japan (VII). Ann. Sci. Kanazawa Univ. 13,1976,1 upon examination gives a list from BC 687 to AD 1600. The catalog by Mossman [Mo in the list] were generally omitted [373 records for London 1707-1895] by Krivsky [‘cancelled’ in the 1st list, as he says] as only the months were given, no dates, so comparison on a date-by-date basis is not possible. I have examined every single catalog and all the data quoted by Krivsky for the period we are discussing 1776-1900, and there are no more data to be had from those sources.
So, at this point, it is up to you to ‘do more work’ be prove your assertion that there are thousands of unknown Euro records that were used by Krivsky. Until then my conclusion stands.
The Hungarian catalog by Rethly & Berkes is interesting because it is derived from a small, well-defined area and because of the great care taken by the authors and of their extensive documentation [also comparing with Fritz]. Here is a plot of their compilation http://www.leif.org/research/Ungarn-Aurorae-1600-1960.png also showing the power spectrum. Needless to say there is no hint of a 60-yr cycle, although the 10-yr solar cycle is evident as well as the well-known 88-yr and 200-yr peaks.

I am an expert specialist in the study of the geomagnetic field and while there are changes, perhaps even waves, on a short time scale of the field, see e.g. http://www.leif.org/research/Geomagnetic-Archeo-Field-Intensity.png there is no evidence [and no agreement] that these changes are external and especially not related to the solar cycle.

Leif, as usual you confuse things.
1) LOO record is in agreement with many European records which were not included in the previous catalog because made of just one entry.
2) even excluding all LOO data, the aurora european record from 1000 to 1900 was already analyzed in
I. CHARVATOVA-JAKUBCOVA, J. STRESTIK, L. KRIVSKY: The periodicity of
aurorae in the years 1001-1900. Studie Geophys. Geod. 32 (1988), 70.
http://www.springerlink.com/content/j23481u8473657q4/
both during the period 1000-1900, and the subperiods 1000-1500 and 1500-1900.
The result they found is in agreement with mine. For example they found two cycles at about 60 and 80-90 years.
For example they write:” Figures 1 and 2 show a certain indication that the 60- i00 year interval probably consits of at least two subintervals.”
That is one cycle around 60 year and another one around 80-100 year
Both cyclicities are found in numerous climate data.
In my paper I clearly state: “Large cycles with periods of about 60, 80–90 years and longer bi-and multi-secular cycles are the most commonly reported.”
Both 60 and 80-90 year cyclicities are found in other solar records, both are related to planetary motion: 60-yr to Jupiter and Saturn; and 80-90yr to Jupiter and Uranus.
So, it is evident that there is more than one cycle which is why you get confused. Essentially you are not able to handle more than one cycle.
Now, let us give a close look at your “high” quality Hungarian record
http://www.leif.org/research/Ungarn-Aurorae-1600-1960.png
You claim that there is no 60-year cycle.
Well let us see:
1) your FFT shows a peak at 60 year together with another at 90 year.
2) Your record of auroras show a clear cycle with maxima located around 1725, 1785 ,1850 and 1910. This make the 60-year cycle.
In particular note the 60-year cycle with a minimum in 1810-1820, maximum in 1840-1850, minimum in 1870-1880, a maximum in 1905-1915 and the following minimum in 1930. The latter pattern from 1880 to 1930 is what we find in the Faroes auroras with a maximum around 1910.
Superimposed to this 60 year cycle we find in those specific data a more irregular pattern with larger peaks that is what produce your FFT peak around 90 year and aroud 180 year (which is anotherr planetary frequency)
In conclusion, your attempts do not prove me wrong, Leif!
You just need to start thinking that there are two major cycles at 60 and 80-90 year, as I write in my papers and other people have found as well, and consider that according the record that one analyzes one cycle may be stressed more than the other for reasons that we do not understand yet although I have some idea of why.

There are no such records as I have demonstrated.
2) even excluding all LOO data, the aurora european record from 1000 to 1900 was already analyzed in…
They use the same original Krivsky record which is not European [remember I have the original list], but heavily dominated by North American records. Example:
1844 has 17 records in the 1988 list, but Fritz’s record only has 12 European records [of which 11 singletons]. The final list [not used by the paper] has 33 records of which 25 are LOOs, thus American. Or 1834: has 6 records in the old 1988 list used by the paper. Fritz’s list has only 11 records of which 10 are singles, but the final list has 28 records of which 24 are LOOs, so again heavily North American.
That is one cycle around 60 year and another one around 80-100 year
Both cyclicities are found in numerous climate data.

Your Figures 4, 5, 8 show no 80-yr cycles in any of the data.
Joan Feynman’s careful study http://www.leif.org/EOS/JA089iA05p03023.pdf concludes:
“we have shown that the long cycle in solar terrestrail relations is real and periodic, that it is present in 1000 years of auroral data, and that the period is 88.4+-0.7 years”
In particular note the 60-year cycle with a minimum in 1810-1820, maximum in 1840-1850, minimum in 1870-1880, a maximum in 1905-1915 and the following minimum in 1930. The latter pattern from 1880 to 1930 is what we find in the Faroes auroras with a maximum around 1910.
The interval 1905-1915 was a period of very low solar and auroral activity.
I have some idea of why
and of many other things as well, it seems. .

‘Prove’ is a strong word. What I have done is comment on the poor quality of your paper. The quality is so low that it is hard to make much sense of it, let alone prove anything.
Let us return to my question that you are evading:
You say “magnetosphere gets stronger”.
How is ‘strength’ measured or defined? and why ‘should aurorae be pushed towards the poles”?

I am familiar with your work and appreciate your expertise. I have some understanding of the development of theory in your field. Regardless, the observational evidence supports the above assertion. As noted below observational evidence is interpreted based on assumed mechanisms. Analysis of the proxy data is complicated. There is a set of linked (in time) anomalous observations concerning these mechanisms. I started looking at the subject from the standpoint of paleoclimatic changes and then moved to geomagnetic changes and the theory/controversy/issues concerning proxy interpretation..
The geomagnetic field forcing is due to the solar magnetic cycle restarting not due to the normal cycle. There are a host of related observational data that can be used to provide support for that assertion and to define the mechanisms.
As I noted above the proxy inferred changes in the geomagnetic field are too rapid and too large to be caused by geological changes. Because the geomagnetic observational evidence requires a physical explanation which requires new mechanism(s) to explain the observation is the reason why there was a 15 year delay in agreement (by agreement I mean that there are published papers and conference discussions, full agreement requires the entire problem to be solved) that the geomagnetic changes did occur.
The interpretation of the geomagnetic proxy data is based on what is believed to be possible. The mantel is conductive. It is physical not possible for a core forcing event to cause the observed very rapid and very large geomagnetic field changes. (The conductive mantel will generate a counter acting emf to resist the changes.) Geomagnetic excursions are assumed to take a couple of thousand years to occur based on an assumed core mechanism. Obviously one cannot directly observe the planet`s core. The core based mechanism is assumed as are aspects of the solar mechanisms. I am appealing to what is believe to be correct as to what is known to be correct by observational evidence to open the door for the possibility that a fundamental assumption could be incorrect.
Those analyzing the ocean floor sediment data assumed the changes in the sediments that indicated geomagnetic field changes caused planetary temperature changes was due to the planetary temperature affecting the proxy data and hence adjusted or corrected the proxy data to make the geomagnetic changes go away (i.e.) to correct for temperature affecting the sediment proxy record. Analysis of different proxy sources (The kiln fired tiles and sundials.) and a special developed sediment analytical technique to find the geomagnetic excursions that correlate with the termination of the interglacial periods was able to determine the magnitude of the geomagnetic field by a method that all agreed was not affected by temperature, has confirmed that the geomagnetic field does change and that there is correlation of the geomagnetic field changes with abrupt climate changes.
Using Svensmark`s mechanism a geomagnetic excursion is capable of terminating an interglacial period. Everyone agrees the glacial/interglacial cycles do occur and that the change from glacial to interglacial and interglacial to glacial does is from the standpoint of climate change and limitations of the known climate forcing mechanisms unexplainable in its rapidity. What is missing is a mechanism to explain why the changes are occurring. A basic quantified analysis indicates Milvankotich’s mechanism cannot explain what is observed. (There are sets of paradoxes associated with Milvankotich’s mechanism.) The forcing mechanism of the geomagnetic field excursions and archeomagnetic jerks are affected by the same parameters that affect insolation at 60N (tilt of the planet and eccentricity of the earth’s orbit and seasonal timing of which hemisphere is pointing at the sun during the perihelion.)
The largest geomagnetic field forcing changes (geomagnetic excursion) such as what caused the Younger Dryas abrupt cooling event cooled the planet for 1300 years. There is concurrent with the Younger Dryas event the largest change in cosmogenic isotopes in the paleo record. The Younger Dryas is a Heinrich event (i.e. The Younger Dryas is one of a cycle of events rather than something unique. There are large cosmogenic isotope changes at the other Heinrich events. I am appealing to the evidence of large cosmogenic isotopes changes at each of the abrupt climate events as smoking gun evidence that there is solar related trigger for what is observed.
A solar cycle is not based analysis of the proxy record, however, directly capable of causing the planet to abruptly cool for 1300 years. The TSI for instance is not reduced for 1300 years. The solar cycle restart causes the abrupt geomagnetic field change. The delay in the core integrating the abrupt geomagnetic field change is the explanation for the duration of the cooling.
Comment:
The old hand waving theory to explain the Younger Dryas was an appeal to changes in ocean circulation as the cause. (Hand waving as there has no explanation as to what could be cyclic changing ocean currents and no quantified of the amount of cooling vs the amount of cooling that would occur due to an abrupt stoppage of the North Atlantic drift current.) An abrupt of thermohaline conveyor is not capable of causing the observed abrupt Younger Dryas climate change. A paper published a couple of years ago shows using GCM that a complete interruption of the North Atlantic drift current will result in cooling that is an order of magnitude too small based on the observations. That analysis is not controversial as simple back of the envelope physical analysis supports that conclusion.
There are concurrent with the Younger Dryas event burn marks throughout the Northern Hemisphere. There is evidence of other large sets of burn marks that occurred at different times. A significant amount of energy is required is required to abruptly change the geomagnetic field. For geological reasons the evidence for the burn marks may not always be preserved. I am appealing that every physical event must have a physical cause. If one accepts that the geomagnetic field is abruptly changing then that abrupt change must have a cause. I am also appealing to the evidence of burn marks that are concurrent with the Younger Dryas abrupt cooling event as a reason to consider the possibility that the assertion may have legs.

The geomagnetic field forcing is due to the solar magnetic cycle restarting not due to the normal cycle.
The solar magnetic cycle has never stopped. Even during the Maunder Minimum the magnetic cycle was continuing. We know this from the fact that the modulation of cosmic rays [caused by the Sun’s magnetic field] during the MM was as strong as today.
The mantel is conductive. It is physical not possible for a core forcing event to cause the observed very rapid and very large geomagnetic field changes. (The conductive mantel will generate a counter acting emf to resist the changes.)
That argument goes the other way to. It is not possible for an external change to penetrate downwards. From spherical harmonic analysis already Gauss [who invented the technique] could show that something like 99.9% of the geomagnetic field [at times when there is not a rare, strong geomagnetic storm] comes from the interior, more precisely the core. BTW, an emf does not mean that a current is flowing, just that there is a voltage difference.

Leif, thank you very much for the file.
About your question, as I have already responded many times above, my statement must be understood in a qualitative term. At the moment I am not referring to a specific and explicit quatitative phenomena that can be directly tested in a direct experiment. And my paper was not focusing in proposing this specific mechanism.
It is more or less when people reason that because humans are wealthier in the summer and less wealthy in the winter, people may say that humans get “stronger” in the summer and “weaker” in the winter.
In the case of auroras, I simply argued that the data that I have analyzed suggest that it is easier to see auroras at the low latitudes every 60 years. At least this is one of the patterns as also the hungarian record show quite well.
For example , in the hungarian record that you plotted
http://www.leif.org/research/Ungarn-Aurorae-1600-1960.png
note the local maxima about in
1610
1670 (missing because the Maunder minimum)
1730
1790
1850
1910
1970 (?) (deduced as a trend from the german record)
In any case, I never claimed in my paper that the 60-year cycle is the only cycle that these data contain, and other longer cycles may overtake it during specific periods.

About your question, as I have already responded many times above, my statement must be understood in a qualitative term.
That is the point: it is qualitatively wrong. And you have clearly not responded in any satisfactory way, otherwise I would not keep asking.
At the moment I am not referring to a specific and explicit quatitative phenomena that can be directly tested in a direct experiment. And my paper was not focusing in proposing this specific mechanism.
The whole premise of your paper is dependent on this mechanism, as you explain: “In this paper, we postulate that the annual frequency occurrence of mid-latitude aurora events is a measure of the level of electrification of the global ionosphere, which is mostly regulated by incoming cosmic ray flux variations (Kirkby, 2007; Svensmark, 2007). When the Earth’s magnetosphere is weaker relative to the surrounding space environment the ionosphere can be highly ionized by cosmic rays, and large auroras would more likely form at the mid-latitudes. This phenomenon would occur because when the upper atmosphere is highly ionized, it would also be electrically quite sensitive to large solar wind particle fluxes and favor the formation of extended mid-latitude auroras. In fact, higher ionization of the atmosphere would mostly occur when the magnetosphere is weaker and cosmic ray as well as solar wind particles can more easily reach the mid-latitudes. Then, the level of atmospheric ionization and of the global electric circuit of the atmosphere should regulate the cloud system (Kirkby, 2007; Svensmark, 2007; Tinsley, 2008). If the above theory is correct, the frequencies of the mid-latitude aurora records should be present in the climate records too.”
There are several errors in that premise:
1) the ionosphere is created and maintained by solar UV. Cosmic rays have nothing to do with this. You are confusing the ionosphere with the lower atmosphere.
2) ” When the Earth’s magnetosphere is weaker relative to the surrounding space environment” is nonsense. Unless you define what ‘weaker’ means, hence my question.
3) ” the global electric circuit of the atmosphere should regulate the cloud system “. It is the other way around: the global circuit is maintained and controlled by thunderstorms. “The earth’s electric current is the accumulated effect of thousands of thunderstorms, mostly in the tropical regions. These storms feed a continuous current from the ground to the ionosphere (a layer in the atmosphere that lies above 100 km (62.5 miles) altitude). The current spreads out around the globe via this layer and returns to earth as the “fair weather current” outside the thunderstorm areas. The whole circuit is referred to as the “global electrical circuit.” From http://www.earthinginstitute.net/commentaries/gaetan_electrical_surface.pdf
4) “If the above theory is correct, the frequencies of the mid-latitude aurora records should be present in the climate records too” but as the theory is not correct the whole premise falls.
I simply argued that the data that I have analyzed suggest that it is easier to see auroras at the low latitudes every 60 years. At least this is one of the patterns as also the hungarian record show quite well.

In any case, I never claimed in my paper that the 60-year cycle is the only cycle that these data contain, and other longer cycles may overtake it during specific periods.
You claim that the 60-yr cycle is the only significant one since 1850, c.f. Figure 2.

As I said above the future will determine whether my results are correct. Please, do not presume to be at the same moment the accuser and the judge. The scientific community will judge my work, not you.
It appears quite clear to me that the Hungarian data confirms the existence of a 60-year cycle, together with other cycles. If you do not see it, I do not know what I can do for you.
You need to decompose the signal of the highest peaks which are unlikely due to the sun spurious to properly see the pattern.

1670 (missing because the Maunder minimum where the sun was quite, so few auroras could be produced)
1730

1970 (?) (hypothetical deduced as a trend from the german record)
There in anothr patterns super imposed to the 60-year cycle that you do not see. The cycle is nevertheless creal to me.
look at the maxima in 1610 and 1730 (after 120 years, this should be easy for you, and the local maxima in 1910, that is 5*60=300 years from 1610.

1) LOO record is in agreement with many European records which were not included in the previous catalog because made of just one entry.
——————————————-
There are no such records as I have demonstrated.

You have demonstrated the reverse. Nicola is saying that that LOO records by acting as a qualifier are making available previous European records (singletons) that were not used in the first Krivsky list. We have already seen a fair chunk of the original unused Fritz record line up with the Loomis data and are now evaluating other European data sets referenced by Krivsky in an attempt to fill in the missing blanks.
To do this evaluation process properly we will need to make available publicly every possible source of European aurora data that Krivsky lists in his references. Are you prepared to do that?
2) even excluding all LOO data, the aurora european record from 1000 to 1900 was already analyzed in…
————————————–
They use the same original Krivsky record which is not European [remember I have the original list], but heavily dominated by North American records. Example:
1844 has 17 records in the 1988 list, but Fritz’s record only has 12 European records [of which 11 singletons]. The final list [not used by the paper] has 33 records of which 25 are LOOs, thus American.

Something not adding up here. There are 8 Fritz entries in the 1996 NOAA (combined Krivsky lists) the rest all have LOO labels. If there was 17 records in 1844 on the 1988 list which records have disappeared? Can you publish a link for the 1988 Krivsky list?
BTW I am in contact with the originator of the NOAA list and working through some of the detail. I am not sure if NOAA is aware of how Krivsky formulated his supplementary list at this stage. More to come.

In reply to Leif Svalgaard,
The emf generated in the mantel resists core changes (emf induces a counter acting current liquid core to resist the change.)
This is a different mechanism.
The surface burn marks that coincide with the timing of the Younger Dryas abrupt climate event are charge discharges from the ionosphere to the surface of the planet. There is a flow of current as the planet attempts to equalize. It is the massive flow of charge that creates the geomagnetic excursion. Depending on the location of the strike the charge flow eventually reinforces or attempts to reverse the geomagnetic field. (As stated above the seasonal timing of perihelion and the tilt of the orbit at the time of the strikes occurring determines the final magnitude of the resultant.)
Remember the smaller version of the event is change the alignment of the geomagnetic field by 10 to 15 degrees.
There are other geological anomalies that support the above assertion. Such as five very large Auckland volcanoes have that have geological separate magma chambers that all erupted simultaneously from a geological standpoint.
The effect is modulated by insulating ice sheets. When the ice sheets melt there is a potential difference in the region of the earth surface that was covered by ice. There are when the ice melts an order of magnitude increase in volcanic activity in that region of the planet when the strikes occur.
It is logical if the geomagnetic excursions and archeomagnetic jerks are real observations there is a physical reason for there occurrence. The burn marks seems to be evidence of the process occurring. There one is set of burn marks that occurred in the North Hemisphere at multiple locations (around 40 if I remember correctly) and the dating of the burn marks coincides with the timing of the Younger Dryas abrupt climate change which is also when a geomagnetic excursion occurred.
If one is looking for a semi periodic solar change that can leave massive burn marks on the earth, the natural next question is what assumption concerning the sun is not correct and what change is required to enable sun to produce the burn marks. I found a entire series of astrophysical papers that basically outlines the jest of the incorrect assumption. The affect is scalable and is observed for larger astrophysical bodies.
There is evidence of restrike in some of the older set of burn marks. That set of burn marks are aligned with the magnetic field at that time. Northwest alignment. The west component is due to the motion of the earth as the massive strikes occur.
At a certain point there is sufficient observational evidence to prove the assertion. The science in each of fields (from an observational standpoint is quite advanced.) The observations from each field and the strawman mechanisms (the astrophysical researchers have a strawman mechanism that is quite useful) fit together like a puzzle.
Is the geodynamo process intrinsically unstable?
http://eprints.whiterose.ac.uk/416/
Recent palaeomagnetic studies suggest that excursions of the geomagnetic field, during which the intensity drops suddenly by a factor of 5^10 and the local direction changes dramatically, are more common than previously expected. The `normal’ state of the geomagnetic field, dominated by an axial dipole, seems to be interrupted every 30 to 100 kyr; it may not therefore be as stable as we thought.
Recent studies suggest that the Earth’s magnetic field has fallen dramatically in magnitude and changed direction repeatedly since the last reversal 700 kyr ago (Langereis et al. 1997; Lund et al. 1998). These important results paint a rather different picture of the long-term behaviour of the field from the conventional one of a steady dipole reversing at random intervals: instead, the field appears to spend up to 20 per cent of its time in a weak, non-dipole state (Lund et al. 1998).
http://geosci.uchicago.edu/~rtp1/BardPapers/responseCourtillotEPSL07.pdf
http://geosci.uchicago.edu/~rtp1/BardPapers/responseCourtillotEPSL07.pdf
Also, we wish to recall that evidence of a correlation between archeomagnetic jerks and
cooling events (in a region extending from the eastern North Atlantic to the Middle East) now covers a period of 5 millenia and involves 10 events (see f.i. Figure 1 of Gallet and Genevey, 2007). The climatic record uses a combination of results from Bond et al (2001), history of Swiss glaciers (Holzhauser et al, 2005) and historical accounts reviewed by Le Roy Ladurie (2004). Recent high-resolution paleomagnetic records (e.g. Snowball and Sandgren, 2004; St-Onge et al., 2003) and global geomagnetic field modeling (Korte and Constable, 2006) support the idea that part of the centennial-scale fluctuations in 14C production may have been influenced by previously unmodeled rapid dipole field variations. In any case, the relationship between climate, the Sun and the geomagnetic field could be more complex than previously imagined. And the previous points allow the possibility for some connection between the geomagnetic field and climate over these time scales.
Point 4: We first reiterate the fact that the “claims” made in our paper regarding correlations between cooling periods and archeomagnetic jerks were actually put forward by Gallet et al (2005, 2006). We do note that the causal relationship between cosmic ray flux and cloud cover suggested by Marsh and Svensmark (2000) would result in a correlation opposite to the one we find if the field geometry were axial and dipolar and this is precisely why we propose a mechanism of dipole tilt or non dipole geometry to interpret our observations. Gallet et al (2005) write: “ Another hypothesis is to assume that the incoming charged particles are deflected towards the poles, where the overall low humidity level due to cold temperatures limits cloud formation. If archeomagnetic jerks indeed correspond to periods of strongly inclined dipole, then the charged particles would interact with more humid air from lower latitude environments, leading to significantly larger cloud production and cooling.” And if this happens, there is no need to “overcome the more direct effect”, as (mis)understood by BD07 (who seem to understand that a growing axial dipole is superimposed on a tilted dipole, which is not the case).
It is therefore not surprising that the tuned curve should reveal the link between solar
activity and 18O. It is moreover interesting to note that this correlation, obtained on an Alpine stalagmite, and therefore evidence of the influence of solar variability on climate, is also found in proxies from other regions around the globe: correlation between times of solar minima and cold episodes in western Europe (Magny, 1993; Holzhauser et al, 2005), modulation of precipitation in the tropics in Northern South America and Yucatan (Haug et al, 2001), in Eastern Africa (Verschuren et al, 2000), and Arabia (Neff et al, 2001); influence on droughts in North America (Yu and Ito, 1999).

Geomagnetic excursion captured by multiple volcanoes in a monogenetic field
Five monogenetic volcanoes within the Quaternary Auckland volcanic field are shown to have recorded a virtually identical but anomalous paleomagnetic direction (mean inclination and declination of 61.7° and 351.0°, respectively), consistent with the capture of a geomagnetic excursion. Based on documented rates of change of paleomagnetic field direction during excursions this implies that the volcanoes may have all formed within a period of only 50–100 years or less. These temporally linked volcanoes are widespread throughout the field and appear not to be structurally related. However, the general paradigm for the reawakening of monogenetic fields is that only a single new volcano or group of closely spaced vents is created, typically at intervals of several hundred years or more. Therefore, the results presented show that for any monogenetic field the impact of renewed eruptive activity may be significantly under-estimated, especially for potentially affected population centres and the siting of sensitive facilities.

Tantamount to saying that I’m not truthful. Bad style. However, I think I have already done that as there was only one catalog with some clout [Hungary]. Remind me of others you would like to see.

There is no link. I have the paper book. A good catch by you. I had counted 1845 as well [hard to count correctly from paper records]. There are 8 F-entries for 1844 on the 1988 list as on the final list. The final list [not used by the paper] has 33 records of which 25 are LOOs, thus American. This still holds even if I screwed up with the 1845.
BTW I am in contact with the originator of the NOAA list and working through some of the detail. I am not sure if NOAA is aware of how Krivsky formulated his supplementary list at this stage. More to come.
I don’t see how they could be aware. They just typed in the lists from Krivsky’s publications. The supplement is clear though: “Only new data sources with abbreviations are referred”. This means that if there were already an entry in the first catalog, there would not be an entry for that in the Supplement. This explains where there is no overlap [except on one day 1850 2 3] between the two lists.

The surface burn marks that coincide with the timing of the Younger Dryas abrupt climate event are charge discharges from the ionosphere to the surface of the planet.
All your long comment may be what it is, but is mostly just a list of stuff with little relevance. for example: there are no charge discharges from the ionosphere to the surface of the planet.
It is the massive flow of charge that creates the geomagnetic excursion
By doing what: magnetizing surface rocks?
The west component is due to the motion of the earth as the massive strikes occur.
There are no ‘massive strikes’. And the earth does not move as a result.
Recent palaeomagnetic studies suggest that excursions of the geomagnetic field, during which the intensity drops suddenly by a factor of 5^10
The current field is 50,000 nT. to drop by a factor of 5^10 [weird number, must be typo?] the field must fall to 0.005 nT which is way below what we can measure.
These important results paint a rather different picture of the long-term behaviour of the field from the conventional one of a steady dipole reversing at random intervals
That is not the conventional view. It is well-known that the field strength changes a lot [factor of 5] all the time.
global geomagnetic field modeling (Korte and Constable, 2006) support the idea that part of the centennial-scale fluctuations in 14C production may have been influenced by previously unmodeled rapid dipole field variations.
This has been known for decades, e.g. http://www.leif.org/research/CosmicRays-GeoDipole.jpg

Leif, let us wait and see.
At the moment I am getting the dynamics of the temperature signal correctly, as the figure above shows. Look in particular at figure 11B above where the decadal and multidecadal variation from 1950 to 2010 is reproduced calibrating the model during the period 1850-1950. So, the model is shown to have forecasting capabilities.
How many presentations did you see that were capable of getting the temperature signal with such a precision? Please refer to just a single published study or Sedona presentation.
At Sedona some people were quite warm, do not worry. You were silent.
As I said, please avoid to be an official referee of my work , because you are not an unbiased and objective person on these topics. Moreover, you have a prejudiced ill-willed disposition against my reseach in general. Thus, you cannot serve as an official referee of my work. Let other people to judge my work, people who are not suggested by you, of course.
Your criticism is not very different from the scientific quality of skepticalscience or realclimate. You can joint them.

It might take a hundred years or more to [dis]prove 60-yr cycles. By that time, we have figured all this out anyway, so nobody is going to care what some 100-yr old flawed papers claimed.

The 30-yr low+30-yr high alternating pattern of PDO is not ‘your’ model. Everybody and his brother claim that, e.g.http://wattsupwiththat.files.wordpress.com/2008/04/la-nina-and-pacific-decadal-oscillation-cool-the-pacific.pdf for recent data
Your ‘model’ is just simplistic curve fitting.
Although you and Easterbrook claim a 60-year cycle for recent data, Bob Tisdale has shown that it does not persist back in time:

Younger Dryas Burn marks

Then, just before the Younger Dryas began, a thin layer of bleached sand was deposited and, in turn, was covered by the dark layer marked “YDB” above. That stratum is called the Usselo Horizon and is composed of fine to medium quartz sands rich in charcoal. The dark Usselo Horizon is stratigraphically equivalent to the YDB layer and contains a similar assemblage of impact markers (magnetic grains, magnetic microspherules, iridium, charcoal, and glass-like carbon). The magnetic grains have a high concentration of Ir (117 ppb), which is the highest value measured for all sites yet analyzed. On the other hand, YDB bulk sediment analyses reveal Ir values below the detection limit of 0.5 ppb, suggesting that the Ir carrier is in the magnetic grain fraction. The abundant charcoal in this black layer suggests widespread biomass burning. A similar layer of charcoal, found at many other sites in Europe, including the Netherlands (3), Great Britain, France, Germany, Denmark, and Poland (4), also dates to the onset of the Younger Dryas (12.9 ka) and, hence, correlates with the YDB layer in North America.
The Younger Dryas paper includes information on the Carolina Bays burn marks. This event occurred prior to the Younger Dryas event. These marks show evidence of restrike. See figure 7.
Carolina Bays. The Carolina Bays are a group of »500,000 highly elliptical and often overlapping depressions scattered throughout the Atlantic Coastal Plain from New Jersey to Alabama (see SI Fig. 7). They range from ≈50 m to ≈10 km in length (10) and are up to ≈15 m deep with their parallel long axes oriented predominately to the northwest. The Bays have poorly stratified, sandy, elevated rims (up to 7 m) that often are higher to the southeast. All of the Bay rims examined were found to have, throughout their entire 1.5- to 5-m sandy rims, a typical assemblage of YDB markers (magnetic grains, magnetic microspherules, Ir, charcoal, soot, glass-like carbon, nanodiamonds, carbon spherules, and fullerenes with 3He). …

“the whole thing is just curve fitting that doesn’t work backwards in time and therefore cannot claim predictive power going forward.”
Leif,
as several readers of this post have already realized, you only show all your bias and/or personal malevolence and luck of objectiveness.
As Lucy summarized above, your comments are nothing but
“Rubbish. Scafetta has already showed six different indices in his paper which all show with stunning clarity the formative presence of a 60-year cycle: PDO, AMO, auroras, monsoons, meteorites, and global temperatures (detrended etc). Thus replication has already succeeded so the claim holds so far. The correlations are highly evocative, I don’t know how to quantify them statistically but visually they shout. Thus the likelihood increases that your apparent non-correlations may have other factors at work, that do not disprove the presence of a 60-year cycle.”
Look at figure 3 of my paper where I show the 60-year cycle since 1700, and numerous other references, where the 60 year cycle and the other cycles have been found up to thousand years uninterrupted.
Again and again, I proved you twrong. However, given the fact that you are not interested in being objective, but you only denigrate and insult, there is no need for me to continue to discuss with you.
As I said, your criticism is not very different from the low scientific quality of skepticalscience or realclimate. You can joint the Team in their propaganda and methods.
About my results the future will tell, Leif, do not worry.

Unfounded utterance on your part

We have just been this process…do we have to do the ground hog day thing?

Nicola is saying that that LOO records by acting as a qualifier are making available previous European records (singletons) that were not used in the first Krivsky list.
——————————-
Nicola has no idea what is going on. He has not examined the providence of the lists.

Rubbish, he has provided his own examples and witnessed others proved here. Please try to refrain from your sophist type behavior.
We have already seen a fair chunk of the original unused Fritz record line up with the Loomis data and are now evaluating other European data sets referenced by Krivsky in an attempt to fill in the missing blanks.
—————
As I said there are no other data sets for the period in question than the ones I have looked at in detail. And no more records.

——————-
To do this evaluation process properly we will need to make available publicly every possible source of European aurora data that Krivsky lists in his references. Are you prepared to do that?
——————————-
Tantamount to saying that I’m not truthful. Bad style. However, I think I have already done that as there was only one catalog with some clout [Hungary]. Remind me of others you would like to see.

It is not bad style to investigate the full data in a proper open manner, taking your word for it is not good enough. Every record referenced by Krivsky must be examined in full. I think if your assumptions are founded NOAA will remove their merging of the data and list the Krivsky lists separately. The first paper to start with should be Loomis, there are discrepancies.
A good catch by you. I had counted 1845 as well [hard to count correctly from paper records]. There are 8 F-entries for 1844 on the 1988 list as on the final list. The final list [not used by the paper] has 33 records of which 25 are LOOs, thus American. This still holds even if I screwed up with the 1845.
So Nicola’s point stands, the 1988 Krivsky list used in the Charvatova paper is not in any doubt of adulteration.

You have no point. Nicola stated the original Krivsky 1988 data used in Charvatova’s paper shows a 60 year period in the aurora data. The aurora data in the 1988 Krivsky data has no doubt of an American bias.

December 4, 2011 6:35 am

Dr. Scafetta
I am a bit disappointed to see that you are still wasting your valuable time on this 60 year periodicity affair; the FFT analysis is not good enough for the purpose. I use different software and what it shows you can see here:
http://www.vukcevic.talktalk.net/Spectra.htm
In general, it agrees what the BEST team presented at the recent Santa Fe conference, they found for the land temperatures 22-24 and 72 year peaks 72=3×24.
You are welcome to ignore it, but if you email me your data file I will check it out.

<"Which examples?"
Nicola and I have both shown you the left over Fritz singletons that coincide with Loomis.
A great aurora is a global phenomenon and will be seen both in Europe and in New England, so if you add New England data, then you’ll see some that coincide with the scattered Euro data.

So, you are saying that Krivsky did a bad job on those. The LOO data is North American, so are hardly relevant for Euro data, but the original Loomis paper is on its way to me, so we’ll soon see.

Please study my papers before criticize them.
Do not imitate Leif that does not understand any more of what he is talking about.
Leif continues to talk about LOO record while results similar to mine have been found by other people also without LOO record using only the European record. And it was documented for centuries even considering aurora data collected before the discovery of America. Thus, Leif continues in his misleading agenda and his poor understanding of data mining thecniques..
In my papers, several power spectra analisis are extensively used together with other thecniques of analisis and with proxy comparisons and a large list of references that further support the claim. Moreover, your way of using FFT is also not appropriate for several mathematical reasons.
The BEST record must be used with great care, because 1) it refers to only land temperature, 2) before 1860 it is made of very few questinable records just from Europe and Atlantic North America which together represent less than 2% of the globe.
Your peak at 72 year is spurious, the peaks in the temperature are around 1880, 1940 and 2000. Which makes 60-year cycles. See figures here
http://wattsupwiththat.com/2010/03/14/dr-nicolas-scaffeta-summarizes-why-the-anthropogenic-theory-proposed-by-the-ipcc-should-be-questioned/

http://wattsupwiththat.com/2011/12/02/hurricanes-and-global-warming-opinion-by-chris-landsea/
where you find this comment about the 60-year cycle
“The remaining data still shows a variation in storm activity that Landsea, like Bill Gray before him, ascribes to the 60 year cycle of the Atlantic Multidecadal Oscillation (AMO). We entered a warm AMO phase in 1995 which coincided with the current period of high storm activity.”

LS: It is the massive flow of charge that creates the geomagnetic excursion
By doing what: magnetizing surface rocks? (William: No. By current flow from the surface of the planet to the core.)
LS: The west component is due to the motion of the earth as the massive strikes occur.
There are no ‘massive strikes’. And the earth does not move as a result.
(William: The electrical discharge from the ionosphere to the surface of the planet occurs over a period of time. Look at the pictures of the Carolina Bays burn marks. There are an estimated 500,000 burn marks. The longest burn marks are 8 km long. There is evidence of restrike. The earth rotates while the event is going on which creates the westward component of the burn marks. Yes, there are currently no discharges from the ionosphere to the surface of the planet. This specific event occurs when the solar magnetic cycle restarts. Provided above is a paper that notes five geological separate Auckland volcanoes erupted geologically simultaneously capturing a geomagnetic excursion – I can provide other papers that provide geological evidence of this event. There would be and is evidence of this event’s affect on the other planets – the massive discharge from the ionosphere to the surface of the planet. The point is this event happens regularly. There is in the geological record correlation with climate events and volcanic eruption in both hemispheres. This event causes the sudden increase in volcanic activity in both hemispheres for regions that are obviously geologically separated. (Think of individual magma chambers feeding volcanoes that located on different faults and completely separated plates.)
As I stated there are published papers and observational data of very large objects, super massive “black holes” that provides a guide to the physics of what is happening. There is an entire set of astronomical anomalies which are explained by this phenomenon. There is a physical reason why this happening. There obviously would be and are dozens of different observational evidence of the phenomenon.)
LS: Recent palaeomagnetic studies suggest that excursions of the geomagnetic field, during which the intensity drops suddenly by a factor of 5^10
The current field is 50,000 nT. to drop by a factor of 5^10 [weird number, must be typo?] the field must fall to 0.005 nT which is way below what we can measure.
(William. Yes that is a typo. The geomagnetic field intensity drops by a factor of 5 to 10.)
Solar cycle 24 is an interruption to the solar magnetic cycle as opposed to a slow down in the cycle. The outcome after an interruption is dependent on the solar cycles prior to the interruption and on orbital factors.
The Heinrich events have a periodicity of roughly 6000 to 10000 years. There was a major event during the Younger Dryas cooling event 12800 year BP and during the 8200 year BP cooling event.
http://sheridan.geog.kent.edu/geog41066/7-Overpeck.pdf
ABRUPT CHANGE IN EARTH’S CLIMATE SYSTEM
“The earliest Holocene abrupt climate changes occurred at 12,800, 8200, 5200, and 4200 B.P. . . .”
The 8200 B.P. event, “lasted four hundred years (6400-6000 B.C.) and, like the Younger Dryas, generated abrupt aridification and cooling in the North Atlantic and North America, Africa, and Asia (Alley et al. 1997; Barber et al. 1999; Hu et al. 1999; Street-Perrot and Perrot 1990).

I use a tailor made software, which doesn’t use the FFT , it produces large output of 4000 data points, regardless of the data-set length, pinpointing frequencies with extreme accuracies.

I show the output for the annual CET from
http://www.metoffice.gov.uk/hadobs/hadcet/cetml1659on.dat
last column
run it through your best software and compare. If you for some reason find it significantly different than spectrum resolution may not be good enough.
My offer still stands to run spectrum, will keep it confidential, email address is on the graph.
I have no reason to doubt the BEST, I get very similar result for the global etc, and the LOD is exactly 72 years as you can see here.

Sorry, Vukcevic
as I said, you need to read my papers first with an open mind, together with their numerous references. And you need to undestand better timeseries analysis. I have already explained you the problems with CET and other local records.
Do not presume to know everything as Leif. Time series analysis is a complex process, it is not only about software, it is about physics, geometry and mathematics as well.

The two remaining singletons are verified by LOO (Hamburg). All “As 1st” type records are either verifying another non Fritz Euro record or are verified by another region in the original Fritz list.

The normalized intensity documents a series of relative paleointensity (RPI) lows recognized in other reference records. Three directional anomalies occurring during RPI lows chronologically correspond to the Laschamp excursion (42 kyr BP),the Blake event (115-122 kyr BP) and the Icelandic basin excursion (190 kyr BP). A fourth directional anomaly recorded at 290 kyr BP during another RPI low defines the ‘Portuguese margin excursion’. Four non-excursional RPI lows are recorded at the ages of the Jamaica/Pringle Falls, Mamaku, Calabrian Ridge 1, and Levantine excursions. The RPI record is characterized by a periodicity of V100 kyr, paleointensity lows often coinciding with the end of interglacial stages. This record sets the basis of the construction of an authigenic 10Be/9Be record from the same sedimentary sequences [Carcaillet et al.,this issue].
Spectral analyses of the RPI record reveal a dominant periodicity at 100 kyr,already reported by other studies (e.g. [41,59,60]). The RPI and N18O records also present a phase shift of 18 kyr: RPI lows often coincide with the end of interglacial or interstadial stages. The geomagnetic moment loss (greater than 30%) over the last two millennia deduced from archeomagnetic results (e.g. [38,39]) might foreshadow the next excursion for the end of our present interglacial, even though this loss started 2200 years ago from an exceptionally high geomagnetic moment value.

>i>1844 is a lean year for Fritz with 12 total entries (Angot). Two of those entries have (?) beside them that Krivsky (one would assume) does not use or (NVR.. no verifying record). The two remaining singletons are verified by LOO (Hamburg). All “As 1st” type records are either verifying another non Fritz Euro record or are verified by another region in the original Fritz list. I do not have the original Fritz list. The remaining LOO entries are yet to be confirmed. I am not sure what your entry Nov 14 represents “LOO As”
I have collected all available data from all catalogs for 1844 and entered them into this spreadsheet: http://www.leif.org/research/Aurorae-1844.xls The format should be self-evident. I get 21 pure North American records and 3 pure Euro records and 5 mixed ones. Try your hand on the file and see what you get. It is clear that many LOO records are validated by there being more than one North American record on the days.

It is clear that many LOO records are validated by there being more than one North American record on the days.
So, it is now established that the latest Krivsky list is dominated [by approx. a factor of three over Euro records] by American entries. This is also clear from the run of the isochasms. In Fritz’s 1881 book ‘Das Polarlicht’ he gives a long list of the isochasm values for all places that have contributed to his catalog. It is instructive to look at a plot of these values [of auroral days per year] as a function of latitude for three regions: America, Europe, and Asia: http://www.leif.org/research/Fritz-Isochasms-vs-Latitude.png
Because of the lopsidedness of the Auroral Oval, the three regions show different tracks, but if you plot against geomagnetic latitude [bottom], they are largely agree. The top plot shows that it is really not a good idea to use the same latitude cutoff [55 degrees] for all regions. If one does that [as Krivsky did], then you end up with about three times as many aurorae in the American sector compared to the European sector [and even more for the Asian sector]. Therefore any compilation or catalog that employs the same cutoff for all regions would end up with many more American entries than Euro entries, just as we find.

“This therefore invalidates Nicola’s claim that his paper is based on European entries.”
Leif,
by any chance, did you read my paper?
Page 2, second column, last paragraph:
“Fig. 2B shows the annual frequencies of mid-latitude auroras obtained from the supplement of the catalogue of mid-latitude auroras <55N from 1700 to 1900. This record contains the historical aurora observations reported MOSTLY in central Europe since 1000AD"
I am not saying that the aurora record is based "only" on European auroras.
This is what you are saying, but that is not what it is written in the paper. 🙂
In any case, even if you are right and some New England "only" auroras are included in the record, this does not justify you to add a huge amount of new England northern auroras inside the record as you want to do, which will definitely bias the record toward norther geomagnetic latitudes and the record will totally lose its character of being a record "mostly" indicative of central Europe and the lower geomagnetic latitudes. In fact, as Silverman and everybody says New England auroras are more likely similar to those in Southern Sweden.
Moreover similar results to mine have been found by using only European Auroras.
Thus, your criticism is totally unjustified and just proves only your biases and prejudices and closed mindness! 🙂

I think nobody has read your paper as carefully as I. It is by this that I have laid bare its flaws.

I have shown that the Krivsky data that you use is MOSTLY North American. The ‘only’ bit comes from Geoff’s (mis)understanding of your paper.
does not justify you to add a huge amount of new England northern auroras inside the record as you want to do, which will definitely bias the record toward northern geomagnetic latitudes and the record will totally lose its character of being a record “mostly” indicative of central Europe and the lower geomagnetic latitudes
I did not add any entries, Krivsky did [most of the LOO records], and you uncritically used what he provided.
In fact, as Silverman and everybody says New England auroras are more likely similar to those in Southern Sweden.
Aurorae are ordered in geomagnetic coordinates and a good part of the data come from England up to the Scottish border at 55N geographic. The geomagnetic latitude of that is such that Denmark and Southern Sweden are in the same geomagnetic latitude range as England. So if you want to exclude Denmark and Southern Sweden, you must exclude England as well. This is even more important in North America, where one should really exclude most records from New England for the same reason. Or, to get better statistics, include New England, England, Denmark, and Southern Sweden on the same footing. After all, the aurora is a global phenomenon and all areas at the same geomagnetic latitude see aurorae with the same frequency.
Thus, your criticism is totally unjustified and just proves only your biases and prejudices and closed mindness! 🙂
Thus, my criticism goes to the core of the flaws in your paper.

…I use independent data of geomagnetic activity, … cosmic ray data, sunspot numbers, and even climate, and show that none of these show any 60-year cycle over long enough time periods [centuries]. Thus replication fails and the claim fails.
Rubbish. Scafetta has already showed six different indices in his paper which all show with stunning clarity the formative presence of a 60-year cycle: PDO, AMO, auroras, monsoons, meteorites, and global temperatures (detrended etc). Thus replication has already succeeded so the claim holds so far. The correlations are highly evocative, I don’t know how to quantify them statistically but visually they shout. Thus the likelihood increases that your apparent non-correlations may have other factors at work, that do not disprove the presence of a 60-year cycle.

The one that should not be in her list is the one we have discussed: aurorae. This is the one I’m concerned with and is the one mentioned prominently in the title of your paper. And is the one that you need to retract based on the results obtained here. Lucy [like you] is hardly a person knowledgeable in the field so invoking her opinion shows how deeply you have sunk to scrape for support.

December 16, 2011 9:25 am

Leif,
the aurora records too presents a 60-year cycle as the solar records and I am not the only person that has said it.
Olmsted, Wolf and Fritz in the 19th century and Charva´tova, Strestnk, Krivsky in more recent times talk about this cycle in their works on the Auroras.
The fact that you do not see it is due to your poor mathematical handling of the data and to the fact that other cycles are present as well such as a 80-90 year cycle and the longer ones, as I say in my paper. Moreover there is the problem with your personal biases and prejudices that makes you blind.

December 16, 2011 9:45 am

… Fritz advocated a 55.5-year period for
the secular variation, a period that Rudolf Wolf had already
inferred from his collection of sunspot data, composed of five
of the 11-year sunspot cycles. The English astronomer John
Herschel, commenting on the importance of the work of Wolf
and Fritz, noted that the secular period of 55 years suits the
auroral observations better than does the period of 65 years
[Herschel, 1864]. Loomis favored a period of around 58 years.

There was indeed in the 1800 century an approximate 60-yr period in aurorae mostly from New England. This period is however not stationary and has disappeared, especially in Mid-latitude European records, e.g. http://www.leif.org/research/Ungarn-Aurorae-1600-1960 to be replaced by the more important 90-yr cycle also conclusively established by Feynman http://www.leif.org/EOS/JA089iA05p03023.pdf
“we have shown that the long cycle in solar terrestrial relations is real and periodic, that it is present in 1000 years of auroral data, and that the period is 88.4 _+0.7 years”
But none of this matters, the flaws in your paper are much more elementary and grave, such as having the physics wrong, claiming to use data from one area when it is really from another one, inappropriate splicing together data from different regions, and so on. It is time to spare yourself further embarrassment and to retract the paper.

Leif, now you are getting very funny.
1) first you denied the existence of a 60-year cycle in the auroras data claiming that I needed to retract my paper based on your non sense.
2) then, forced by my hard evidences taken from your own web-site you have acknowledged that several people expert in aurora data have acknowledged the existence of a 60 year cycle.
3) now, you are claiming that the 60 year cycle does not appear in the solar records during the last century.
Unfortunately for you, that depends on the solar sequence that you use. There are several solar sequences, including your beloved northern New England aurora records that peak in 1880 and 1940. Then you may add the ACRIM TSI that peaks in 2000, and you get two nice 60-year cycles since 1880 in perfect phase with the 60-year cycle of the temperature.
I explain this things in my paper, but you did not read it, don’t you?
The fact, dear Leif, is that your solar models claiming a “flat” solar activity are wrong!

It seems you have been taken in by your own flawed Figure 2B which shows the latest Krivsky data dominated by New England aurorae. The ‘peaks’ in 1880 and 1940 that are shown in the Figure are actually valleys [as you plot the frequency upside down], so unless you claim that ACRIM TSI also was at a minimum in 2000 you are in trouble.

Leif,
your argument is based on the idea that data that do not fit your ideology should be rejected.
So, you are looking at the problem only from one and single point of view, which is the one of the “flat sun” believers who commit the same error of the “flat Earth” believers that do not understand that there are regions of the Earth that present a cold season simultaneously to other regions of the Earth that present a hot season.
Try to understand that there are multiple points of view were the relative patterns may appear to be negative-correlated at times.
The data do not support your understanding of solar/terrestrial interation dynamics, so are the data wrong or is your theory wrong? The issue requires a detailed analysis which cannot be solved in just one paper but requires a detailed study.
So, try to understand that this is “frontier research”. My paper does not contain any factual error that you can objectively criticize. Your criticism is only that my paper does not address and explain every possible issue one might think about. But no paper solves everything at once.
You simply need to learn to respect people who have ideas and opinions that may be different from yours, that is all.

This is not even ‘research’. And you can replace ‘frontier’ by ‘fringe’ with no loss of meaning. I have documented as host of factual errors both regarding the physics and even more glaringly the ‘analysis’ [although what you do can hardly be called that].

I respect peoples opinions or papers. The person does not enter the equation, if only in a negative way by losing reputation by not wishing to learn. To be respected, an idea has to be formulated clearly, has to be backed up by correct analysis, and has to be physically plausible. Yours fail on all those points.

You can download several reconstructions from http://www.leif.org/research/TSI%20(Reconstructions).txt or from an Excel file with same name but extension .xls. The base for the reconstruction is the realization that there is no ‘background’ secular change in the sun’s magnetic field, as for example shown by Schrijver et al http://www.leif.org/EOS/2011GL046658.pdf and by our own work http://www.leif.org/research/2009JA015069.pdf and http://www.leif.org/research/SHINE-2011-The-Forgotten-Sun.pdf

I gave a look at your TSI reconstruction
http://www.leif.org/research/TSI%20(Reconstructions).txt
It appears that according to you the TSI was almost flat from 1700 and 2000. However in 2007.5 it had a huge decrease at 1365.35 W/m^2 that makes your TSI in 2007.5 far the lowest point since the Maunder Minimum in 1700 when TSI was far higher at 1365.47 W/m^2
Are you absolutely sure that your TSI is correct?

Other people, e.g. Schrijver et al. have signed on to that, so I don’t need to do this. My talking point will be that at any solar minimum the Sun relaxes to the same state [ignoring the residual effect of a few sunspots] with the same magnetic field, the same TSI, the same cosmic ray modulation. You can learn more here: http://www.leif.org/research/Historical%20Solar%20Cycle%20Context.pdf or here http://www.leif.org/research/IAUS286-Mendoza-Svalgaard.pdf or here http://www.leif.org/research/GC31B-0351-F2007.pdf [this was the poster just next to yours]

I have no idea what you are talking about. My reconstruction stopped in 2007 with a value only a tenth of a Watt different than in 1700. You are incoherent. ‘Far higher’? A tenth of a Watt…. Huge decrease?

I did not know that you are an expert in solar-climate relations. You have never published anything in the field.
Climate is the average weather over a long interval, say 20-30 years. Back in the 1970s I was co-author of a series of papers in Science, Nature, and other prestigious journals that revived the Sun-Weather-Climate field. The specific effect was called the Vorticity-Area-Index Effect. See e.g. http://www.leif.org/EOS/Nature/255539a0.pdf and http://www.leif.org/EOS/Nature/280845a0.pdf and many others, too numerous to mention. Some papers by others who were inspired by our findings include http://www.leif.org/EOS/Nature/255539a0.pdf and http://www.leif.org/EOS/Nature/275200b0.pdf and many others. Unfortunately, the effect proved spurious as all sun-weather-climate effects eventually do, and the excitement and the numerous conferences flowing from that eventually died. Brian Tinsley still believes the effect is real. Markson had some ideas about influences on atmospheric electricity http://www.leif.org/EOS/Nature/273103a0.pdf and so on. The original discovery papers can be found on ADS: http://adsabs.harvard.edu/abs/1973Sci…180..185W http://adsabs.harvard.edu/abs/1974JAtS…31..581W and http://adsabs.harvard.edu/abs/1979Sci…204…60W
BTW, one of other authors was Walter Orr Roberts, the founder of NCAR. I worked with him at NCAR for a time in 1973-74. I have a background in Meteorology and Atmospheric Physics, having studied and worked at the Danish Meteorological Institute in the 1960s. So, I do know what I’m talking about. More homework you should have done.

Sorry Leif, that is exactly what I said. In 1700 your TSI 1365.47 W/m^2 and in 2007.5 it was 1365.35 W/m^2
The difference was 0.12 W/m^2 with the value in 2007 below the value during the Maunder minimum.
The 0.12 W/m^2 difference cooling in 2007 is a huge change considering that your TSI is practically flat and always above 1365.47 before 2000

Sorry Leif, that is exactly what I said. In 1700 your TSI 1365.47 W/m^2 and in 2007.5 it was 1365.35 W/m^2. The difference was 0.12 W/m^2 with the value in 2007 below the value during the Maunder minimum.
The 0.12 W/m^2 difference cooling in 2007 is a huge change considering that your TSI is practically flat and always above 1365.47 before 2000

Not only should you have done more homework, you also need a course in arithmetic. Firstly, 1700 is coming out of the Maunder Minimum [SSN=5], not in the depth of it [SSN=0]. Secondly, 0.12 W/m2 is less than one tenth of the solar cycle variation, so it is not huge. If the solar cycle variation due to TSI is, say 0.15K [which I think is twice the actual value, but I’ll throw you that bone], then the cooling due to 0.12 W/m2, would be 0.01K, not particularly huge. Thirdly, TSI is not flat, it has a 1.5 W/m2 solar cycle variation. No huge changes anywhere. Fourthly, the uncertainty on any reconstruction is certainly more than 0.1 W/m2 anyway. E.g. even the ‘observed’ ACRIM TSI is wrong by up to 0.5 W/m2 at times. And PMOD is off by 0.25 W/m2 [talking into account the constant difference of 4.5 W/m2] due to the precision aperture not being in the optimal place, and the erroneous assumption that a non-exposed radiometer does not degrade, among other factors.

Yes, I do agree with you. 🙂

You just didn’t know it. Now you do.

December 18, 2011 7:30 pm

See, Leif.
You need to explain the LIA and the MWP and the other climatic patterns. There is no way to get those temperatures with your flat TSI which would imply mumtidecadal and secular temperature changes of the order of 0.01 K, as you say.
So, I would say that your TSI reconstruction is by far the less realistic TSI reconstruction proposed in the scientific litterature.

The Sun has nothing to do with this. That is the obvious conclusion, see: http://www.leif.org/research/Does%20The%20Sun%20Vary%20Enough.pdf
So, I would say that your TSI reconstruction is by far the less realistic TSI reconstruction proposed in the scientific literature.
The literature is full of wrong reconstructions, starting with Hoyt and Schatten’s, then Lean 2000, Wang, Krivova, etc. Note that all of those have slowly ‘flattened’ out with time, see http://www.leif.org/research/TSI-recon3.png culminatin=g with mine and with Preminger’s and Schrijver et al. The usual riposte to this is that people say it is not TSI, but magnetic field, cosmic rays, UV, planets, Unknown unknowns, etc in heir panic and desperation to invoke the sun after all. By saying ‘realistic’ you are assuming what you want to show, thus using a circular argument.

Here is the Abstract I have submitted [I may change it at any time]
Title: ‘The long-term variation of solar activity’
Abstract:
In his famous paper on the Maunder Minimum, Eddy (1976) conclusively demonstrated that the Sun is a variable star on long time scales. Lockwood et al. (1999) provided further insight to the nature of such long-term change by using geomagnetic activity indices to show that the Sun’s open magnetic flux underwent significant – factor of two – changes during the course of the last century. The Lockwood et al. study reinvigorated the field of long-term solar variability and brought space data into play on the topic. After a decade of vigorous research based on cosmic ray and sunspot data as well as the geomagnetic activity however, an emerging consensus reconstruction of solar wind magnetic field strength has been forged for the last century. This is a significant development because, individually, each method has uncertainties introduced by instrument calibration drifts, limited numbers of observatories, and the strength of the correlations
employed. The consensus reconstruction shows reasonable agreement among the various reconstructions of solar wind magnetic field the past100 years. New magnetic indices open further possibilities for the exploitation of historic data. Reassessment of the sunspot series and new reconstructions of solar Total Irradiance also contribute to our improved knowledge (or at least best guess) of the environment of the Earth System, with obvious implications for climate debate and management of space-based technological assets.

It does not appear to be very difficult to add “Svalgaard” to that long list. 🙂
So, you are going to say that the sun does not have any influence on the climate, because its variability according to your “flat-sun” model would imply changes on the secular scale of just 0.01 K. And that the TSI in the minimum in 2007 was at its lowest minimum since 1700 “far” below the minimum in 1700 (during the Maunder minimum) and during the minima of the Dalton minimum. Right?
However, you have missed to make the above important and extraordinary finding explicit in your abstract, although.
I suspect that if your TSI model is correct, the only way to explain climate changes, then, is to stress at the maximum a direct planetary influence about which I also talk in my paper as an extreme hypothesis 🙂

You will have noticed that they all are converging on mine.
And that the TSI in the minimum in 2007 was at its lowest minimum since 1700 “far” below the minimum in 1700 (during the Maunder minimum) and during the minima of the Dalton minimum. Right?
Except that the 1700 values is not far below 2007 [or 2008] and 1700 is not ‘during’ the Maunder minimum. The correct statement is that at all minima, TSI has the same value [subject to minor fluctuations caused by residual sunspots]. The direct observed values since 1978 bears this out, now that PMOD has been shown not to be any lower than during 1996. Your ‘far below’ is just nonsense, not worthy of a serious scientist.
However, you have missed to make the above important and extraordinary finding explicit in your abstract, although.
was implicit in “new reconstructions of solar Total Irradiance”. We have been saying this for years now and the community is taking notice.
I suspect that if your TSI model is correct, the only way to explain climate changes, then, is to stress at the maximum a direct planetary influence about which I also talk in my paper as an extreme hypothesis 🙂
Not at all. Any sufficiently complex system undergoes random, internal fluctuations, see e.g. http://pespmc1.vub.ac.be/Papers/ELIS-complexity.pdf
Note that Judith Lean points out that long-term changes in TSI have not been detected and doubts that they occur. I grant that this is controversial, which is why we are having workshops to address those issues: http://www.leif.org/research/Svalgaard_ISSI_Proposal_Base.pdf
So, why don’t you offer to pay the travel for me so that I can come? Or you may suggest them to invite me
I don’t think you can bring anything of value to the workshop, so it will be hard to justify an invitation. But, you could make an effort yourself [$2000 is a small price to pay] to further your education in Sun-Climate relations.

Question..hmm somewhat related..
What affect do thunder storms have on geomagnetic indices?
See article below
NASA’s Fermi Catches Thunderstorms Hurling Antimatter into Space
01.10.11
..”Even though Fermi couldn’t see the storm, the spacecraft nevertheless was magnetically connected to it,” said Joseph Dwyer at the Florida Institute of Technology in Melbourne, Fla. “The TGF produced high-speed electrons and positrons, which then rode up Earth’s magnetic field to strike the spacecraft.”
The beam continued past Fermi, reached a location, known as a mirror point, where its motion was reversed, and then hit the spacecraft a second time just 23 milliseconds later. Each time, positrons in the beam collided with electrons in the spacecraft. The particles annihilated each other, emitting gamma rays detected by Fermi’s GBM..

“You will have noticed that they all are converging on mine.”
not really, none of them agrees with you. Moreover Shapiro is proposing the opposite of what you claim. See here:
http://wattsupwiththat.com/2011/05/10/new-solar-reconstruction-paper-suggests-6x-tsi-change-than-cited-by-the-ipcc/
Leif, your model does not explain absolutely anything by your own admission. Carla is right: what a mess you are going to say in Japan!
Solving a physical problem with a statement such as “Any sufficiently complex system undergoes random, internal fluctuations” proves only that your model does not explain anything and that you have no clue of what you are saying or of the phenomena under study.
Lean’s model contains a naive error of physics as I pointed out many times. Essentially she claims that the climate responds linearly to the forcings, which is clearly false, so she does not get the appropriate trendings. You need to read my papers to educate yourself. For example
N. Scafetta, “Empirical analysis of the solar contribution to global mean air surface temperature change,” Journal of Atmospheric and Solar-Terrestrial Physics 71 1916–1923 (2009), doi:10.1016/j.jastp.2009.07.007.

Of course one would not expect perfect agreement. What is important is that they are converging to a flatter curve. The Shapiro proposal has not found general acceptance and has many problems as we shall discuss. The biggest being that half of the change has taken place since 1900, and we know that the Sun’s magnetic field and UV emission back then is just what it is today.
Leif, your model does not explain absolutely anything by your own admission.
Because there is nothing to explain. The Sun does not modulate the climate.

The climate response is irrelevant for TSI reconstruction. Using the forcing would be circular reasoning. As you are doing in the papers you cite.

No, as you do not bring anything of value to the discussion.

December 19, 2011 10:19 am

Leif,
as you have clearly stated you think that the sun has “zero” effect on the climate and there is “nothing to explain” in any case. So, your point of view is that workshops like that you will be attending, which would like to address solar-climate influences, are totally useless and just a waste of time and money.
Don’t you think that such your position is quite extremist with so many other people thinking otherwise? Not even the IPCC is so extremist like you.
A discussion implies people with different ideas that compare the alternative theories in their capability of interpreting reality. So, you should promote people with different ideas instead of promoting only yourself and people (very few indeed) who think like you.
Whether or not my contribution will be of value, should be decided by the scientific community, don’t you think?
So, by offering the 2000$ for my trip who will give a very good example of open mind. So that even if your theories will be found to be unlikely, people there might still thank you for having allowed my partecipation. I may update my talk given in Japan last year invited by the Japan Society for the Promotion of Science.
About circular reasoning, please note that your reasoning is based on the assumption that TSI variations are implicit in the solar magnetic field alone, which may not be the case.

No, it is not useless to discuss the issues. And there are people [e.g. Svensmark] with a different opinion.

No, some vetting up front is always done. E.g. by editors and conference organizers. And the scientific community generally takes a rather dim view of what you are peddling.

I do not have an open mind because the data are such a hard constraint that one does not the luxury to disregard them on the pretext of open-mindedness.

We do not need a rehash of old, tired talks. And it is not my decision whom to invite. Anybody is free to register to attend.
About circular reasoning, please note that your reasoning is based on the assumption that TSI variations are implicit in the solar magnetic field alone, which may not be the case.
The 0.1% variation of TSI depends on the magnetic field as evidenced by the very close fit of observed TSI to observed magnetic activity, the remaining 99.9% does not. Since the energy generated in the core takes ~250,000 years to diffuse out through the radiative zone, variations of a time scale much shorter than that are completely washed out. And as I pointed out no variations yet have been observed. To say that in order to explain the climate variations we see, TSI must vary accordingly is the circular reasoning you employ in your papers.

December 19, 2011 1:28 pm

Leif, my papers do not adopt circular reasoning and I do not build the solar models on the temperature data. My papers adopts TSI model proposed by several other people and contain numerous tests to check that the models have reconstructiong and forecasting climatic capabilities. And my models are shown to actually get the data as well as it could be done.
Your models instead do not explain anything, no climate change patterns as known during any time scale can be reproduced by your TSI model because the variation is too small.
“The 0.1% variation of TSI depends on the magnetic field as evidenced by the very close fit of observed TSI to observed magnetic activity”.
Well, it is not so close. It depends on the TSI records that you are using. Remember that PMOD alters some TSI observations to make its composite to fit the decadal trending of the observed magnetic activity. That is true circular reasoning! ACRIM presents a very different pattern.
“Since the energy generated in the core takes ~250,000 years to diffuse out through the radiative zone, variations of a time scale much shorter than that are completely washed out.”
The things may not be so simple, the solar interior may not be in perfect equilibrium 🙂
Who knows why there is a variation in the solar cycle 🙂

You pick the TSI reconstruction [e.g. involving ESS2] that fits the temperature best. This is circular reasoning. The TSI models you cherry pick have been constructed based on a myth, namely that solar activity now is the highest in the last several thousand years and that the group sunspot number is correct plus that there is a background that varies with the envelope of the solar cycle. All of these assumptions are dubious, if not outright wrong.
Your models instead do not explain anything, no climate change patterns as known during any time scale can be reproduced by your TSI model because the variation is too small.
Which simply shows that the sun does not control the climate.
It depends on the TSI records that you are using.
You tend to cherry pick to get a match with the temperature, thus circular reasoning.
Remember that PMOD alters some TSI observations to make its composite to fit the decadal trending of the observed magnetic activity. That is true circular reasoning! ACRIM presents a very different pattern.
TSI comes from the magnetic network so must match that. If it doesn’t it is wrong. ACRIM has recently been recalibrated. ACRIM disagrees with DIARAD and PMOD so must be discarded.
“Since the energy generated in the core takes ~250,000 years to diffuse out through the radiative zone, variations of a time scale much shorter than that are completely washed out.”
The things may not be so simple, the solar interior may not be in perfect equilibrium 🙂

‘may’ not be? The interior does not have to be in ‘perfect equilibrium’ for the diffusion wash-out to work.
Who knows why there is a variation in the solar cycle 🙂
There is a growing body of knowledge on this, e.g. the work by Choudhuri and Nandy. Even Babcock and Leighton had it right: The build up to maximum is deterministic [which is why precursor prediction works], but the movement of flux to the polar regions is a random process which can fluctuate due to contingencies. Only 1/1000 to 1/100 of the erupting flux makes it to the poles. One should not build theories on ignorance: “who knows, so anything goes”.

In your paper you assume that the TSI record is a proxy for climate changes:
“The above equations assume that the TSI record is used as a proxy for the overall climate sensitivity to solar changes”. It is therefore not a surprise that you find it is. That is but one of the several examples of circular reasoning.

As Lean pointed out at Sedona [you were there so should know]:
“Solar Irradiance Decadal Trends: Real Variability (unlikely) or Instrument
Instability (likely)?
Decadal trends in solar irradiance are not yet detectable from uncertainties caused by instrument instabilities in the measurements.
Total Solar Irradiance: – differences between successive solar minimum are smaller than measurement uncertainties”

“These results provide further support for the hypothesis that the quiet Sun is constant over solar cycle time intervals”

ACRIM-gap and total solar irradiance revisited: Is there a secular trend between 1986 and 1996?
N. A. Krivova, S. K. Solanki, T. Wenzler
“A gap in the total solar irradiance (TSI) measurements between ACRIM-1 and ACRIM-2 led to the ongoing debate on the presence or not of a secular trend between the minima preceding cycles 22 (in 1986) and 23 (1996). It was recently proposed to use the SATIRE model of solar irradiance variations to bridge this gap. When doing this, it is important to use the appropriate SATIRE-based reconstruction, which we do here, employing a reconstruction based on magnetograms. The accuracy of this model on months to years timescales is significantly higher than that of a model developed for long-term reconstructions used by the ACRIM team for such an analysis. The constructed ‘mixed’ ACRIM — SATIRE composite shows no increase in the TSI from 1986 to 1996, in contrast to the ACRIM TSI composite.
So much for that. Down the drain goes your argument.

December 20, 2011 6:19 am

Leif, your comments above just prove your numerous biases and personal ostility.
Possible that you are not able to read a paper with fairness and open mind?
1) “You pick the TSI reconstruction [e.g. involving ESS2] that fits the temperature best.” No, I used the TSI reconstruction that was considered sufficiently accurate and represents more or less an average among the proposed TSI reconstructions. My ESS2 and ESS1 curve use the same TSI reconstruction. The difference is in the two detected time constants of the climate system. The final solar signature is given by the sum of ESS1 and ESS2. The free parameters of the model are only calibrated during the period 1980-2000 and the validation of the model goes back to 1600 when the cooling associated to the Maunder minimum and the other major pattern are recovered!
2) “In your paper you assume that the TSI record is a proxy for climate changes”. That is a strarting assumption which is confirmed by the final results which are depicted in this figure
http://pielkeclimatesci.files.wordpress.com/2011/11/figure3.gif
3)”ACRIM disagrees with DIARAD and PMOD so must be discarded. ”
What kind of reasoning is this? PMOD alters the satellite TSI data, while DIARAD uses a naive average among all records which makes its composite different from all available observations.
You may be interested in this paper
http://www.fel.duke.edu/~scafetta/pdf/Scafetta-easterbrook.pdf
read section 3 and look careful at figure 7 around 1989 to understand the error made by PMOD in dealing with the Nimbus record.
4) “Krivova, S. K. Solanki, T. Wenzler”. Their argument is foolish. First they calibrate their SATIRE model on PMOD, and then they claim to have disproven ACRIM.
You need to read our paper N. Scafetta and R. Willson, “ACRIM-gap and Total Solar Irradiance (TSI) trend issue resolved using a surface magnetic flux TSI proxy model”, Geophysical Research Letter 36, L05701, doi:10.1029/2008GL036307 (2009).
http://www.fel.duke.edu/~scafetta/pdf/2008GL036307.pdf
To understand that Krivova, S. K. Solanki, T. Wenzler were not able to disprove our original argument, so they changes their model of reference. We will respond, do not worry.

The free parameters of the model are only calibrated during the period 1980-2000
That is your mistake. You pick a model where there is a large difference between the minima. As Lean, Krivova, Chapman, and Willson agree there is no difference within the uncertainty of the data.
2) “In your paper you assume that the TSI record is a proxy for climate changes”. That is a starting assumption which is confirmed
So circular as I said. Your Figure caption also has an error [try to see if you can spot it]
3)”ACRIM disagrees with DIARAD and PMOD so must be discarded. ”
What kind of reasoning is this? PMOD alters the satellite TSI data

Nobody can alter the data. Everybody adjusts the data to make a composite, as the data has offsets that are different for every satellite. As reported at Sedona, the systematic errors are so large that there is no now evidence for any difference between minima. The null-hypothesis must then be that, indeed, there is no difference. With no difference your arguments are invalid.
4) “Krivova, S. K. Solanki, T. Wenzler”. Their argument is foolish.
Yet you cherry pick a model made by fools then. It is telling that the very people who construct your TSI series say that you misuse their data. But then, you label them fools. But are happy to use their reconstruction even in the face of them telling you is is misuse.
To understand that Krivova, S. K. Solanki, T. Wenzler were not able to disprove our original argument, so they changes their model of reference. We will respond, do not worry.
No need to respond as nobody would care.

In case you are not following the science involved, here is Willson’s presentation at AGU 2011:
ABSTRACT FINAL ID: GC21C-04
TITLE: Revision of ACRIMSAT/ACRIM3 TSI results based on LASP/TRF diagnostic test results for the effects of scattering, diffraction and basic SI scale traceability
SESSION TITLE: GC21C. Climate Change and the Sun: Quantifying Solar Terrestrial Contributions to Global Change Including Updated Total Solar Irradiance Records I
AUTHORS (FIRST NAME, LAST NAME): Richard C Willson
ABSTRACT BODY: The ACRIMSAT/ACRIM3 – SORCE/TIM TSI scale difference was investigated through diagnostic testing of ACRIM3 flight backup instrumentation in the Laboratory for Atmospheric and Space Physics Total Solar Irradiance Radiometer Facility (LASP/TRF). A preliminary downward correction of 5000 ppm was derived to conform ACRIM3 results to the TRF indicated effects of scattering, diffraction and basic radiation scale traceability to the international system of units (SI). Additional testing and analysis is required to reduce the uncertainties of these results which is estimated to be +/- 500 ppm [0.7 W/m2]. The net effect of the TRF corrections places average ACRIM3 TSI results slightly lower than those of SORCE/TIM but within the uncertainty of the TRF comparisons.
Let me repeat: there is no evidence that there is any difference between minima. There is no evidence [as you claim: “Increasing TSI between 1980 and 2000 could have contributed significantly to global warming during the last three decades”] that TSI has increased. On the contrary, there is lots of evidence to the contrary. Of course, such falsifications will always be ignored by true believers of a cause.

In their careful analysis of TSI http://www.leif.org/EOS/2010GL045777.pdf Kopp and Lean conclude:
“[29] In addition to the offsets, published irradiance observations composing the 32‐year TSI database lack coherent temporal structure because of inconsistent trends that indicate the presence of uncorrected instrumental drift and are not explained by known sources of solar irradiance variability. A regression model that determines the relative proportion of sunspot and facular influences directly from the SORCE/TIM data accounts for 92% of observed variance and tracks the observed trends to within TIM’s stability. This close agreement provides further evidence that TSI variations are primarily due to surface magnetic activity. Uncorrected instrumental drifts are the likely reason that none of the irradiance composites show consistency in their trends nor achieve the high level of agreement with the model as the TIM does.
[30] Climate change studies that use published TSI time series to accredit solar responses must be cognizant of the possible errors in the record; otherwise climate variability is incorrectly attributed to solar variations that are in fact instrumental drifts. The current database is too short and imprecise to establish the magnitude of long‐term irradiance changes, or to alleviate conflicting claims of irradiance variations driving significant climate change in recent decades. Achieving 0.01% uncertainties with stabilities <0.001% per year (the future TIM instrument measurement goals) will help discern secular changes in solar irradiance, making the 32‐year TSI climate data record more robust against potential measurement gaps and more reliable for climate change applications."
So, your 'findings' are built on the shifting sands of measurements uncertainty. Pay special attention to Kopp and Lean's admonition: " Climate change studies that use published TSI time series to accredit solar responses must be cognizant of the possible errors in the record; otherwise climate variability is incorrectly attributed to solar variations that are in fact instrumental drifts". You seem to fail in this regard.

“Nobody can alter the data. Everybody adjusts the data to make a composite”
Dear Leif,
Everybody adjust the data moving the entire record up or down for creating a TSI composite. But Frohlich in addition to that has seriously manipulated the Nimbus data to make his PMOD composite.
See figure 6 in
http://www.fel.duke.edu/~scafetta/pdf/Scafetta-easterbrook.pdf
to understand how big is the manipulation of the data made by Frohlich.
Read the statement from Hoyt where he strongly criticize Frohlich for the manipulation. Hoyt says:
“Frohlich’s PMOD TSI composite is not consistent with the internal data or physics of the Nimbus7 cavity radiometer.”
About ACRIM record you are quite confused.
The ACRIM adjustment did not change the TSI composite trending at all. See the figure in
http://acrim.com/TSI%20Monitoring.htm
About Kopp and Lean, I wrote time ago to Kopp explaining him the physical errors in Lean’s model he adopted in his paper with Lean. This was his response (on Nov/01/2011):
Hi Nicola,
your point is valid. In answering your question, I was focused on the 11-year solar cycle frequency only, where allowing for lags in the regression would deal with heat storage. But you’re right, that neglects any possible long-term trend in solar forcing, which would have a greater impact, a different lag, and a different sensitivity because of the different (low) frequency.
Thanks for the question — I’ll keep in mind both the long-term and the 11-year frequencies (and others) next time! Greg
So, learn to be more objective. Yours is nothing but an arrogant and closed mind behavior. Greg said that I am right.
“Since you will not bring anything of value [to wit: your circular reasoning here] I cannot in good conscience do so.”
did you change idea now?

None of this matters as the uncertainties are so great that there is no evidence for any changes.
But you’re right, that neglects any possible long-term trend in solar forcing, which would have a greater impact, a different lag, and a different sensitivity because of the different (low) frequency.
And this does not matter either as all Greg was pointing out was that there is no data for the long-term variation. You calibrated using 1980-2000, so also did not use any long-term data.

Who cares what Frohlich did? I don’t use his data. In fact I have shown that the Virgo data are not correctly calibrated: http://www.leif.org/research/PMOD%20TSI-SOHO%20keyhole%20effect-degradation%20over%20time.pdf
At Sedona, Schmutz admitted that much and at AGU we learned that the keyhole spikes are due to uncompensated thermal changes introduced by turning over the spacecraft.
The fundamental issue is “This close agreement provides further evidence that TSI variations are primarily due to surface magnetic activity. Uncorrected instrumental drifts are the likely reason that none of the irradiance composites show consistency in their trends nor achieve the high level of agreement with the model as the TIM does”. Are you now claiming that Greg is wrong on that.

December 20, 2011 7:55 pm

Leif,
there is not a “close” agreement between TSI and magnetic activity. The agreement is approximate as the agreement among any solar records. You find a vague agreement in the sense that all present an 11-year cycle, for example.
The major difference between PMOd and ACRIM composite is during the ACRIM gap. PMOD alters the NImbus data to make it to fit his models. One major reason for the correction is the claim that at the end of september 1989 Nimbus sensor suddenly increased theirsensitivity by 0.4 W/m^2. As I have proven in my paper this “sudden-one-day- shift did not occur. Thus, PMOD composite is wrong. The huge degradation of Virgo does not have anything to do with this issue.
“which falsifies your claim that “Increasing TSI between 1980 and 2000 could have contributed significantly to global warming during the last three decades” as TSI as per this figure did not increase.”
No, Leif, TSI increased from 1980 to 2000 as I said. Even a small increase of TSI can be magnified by ten times by the climate system through the cloud response.
Don’t you see that you do not know much about these things while my partecipation to the conference woud be much appreciated?

Greg finds for TIM [which is the best we have] that 92% of the variation of TSI matches that of magnetic activity. For RMIB it is 85%, for PMOD 83%, but for ACRIM we are down to a low 66%. So TSI matches magnetic activity very well, except that ACRIM is so poor that it only captures 66%.
Chapman and Ulrich also find that the variation matches the magnetic field extremely well. Here is Chapman’s Sedona abstract:
Modeling TSI Variations from SORCE/TIM
Gary A. Chapman [gary.chapman@csun.edu], A. M. Cookson, and D. G. Preminger, San
Fernando Observatory, California State University, Northridge
Total Solar Irradiance (TSI) measurements have been available from the TIM instrument
on the SORCE spacecraft since 2003. We compare TSI data with photometric indices from red
and K-line images obtained on a daily basis at the San Fernando Observatory (SFO). For 1375
days of data from 2003 March 02 to 2010 May 05 we compare the data in linear multiple
regression analyses. The best results come from using only two photometric indices, the red
and K-line photometric sums, and SORCE TSI 6-hour averages interpolated to the SFO time of
observation. For this case, we obtain a coefficient of multiple correlation, R^2 of 0.94798 and a
quiet-Sun irradiance, S_o = 1360.778 +/- 0.004 W/m^2. These results provide further evidence against hypotheses that link TSI variations to assumed changes in the quiet Sun.

Modeling Total Solar Irradiance Variations Using Automated Classification Software on Mount Wilson Data

Solar Physics, Volume 261, Issue 1, pp.11-34 (2010)
doi: 10.1007/s11207-009-9460-4
“We present the results using the AutoClass analysis application available at NASA/Ames Intelligent Systems Div. (2002) which is a Bayesian, finite mixture model classification system developed by Cheeseman and Stutz (1996). We apply this system to Mount Wilson Solar Observatory (MWO) intensity and magnetogram images and classify individual pixels on the solar surface to calculate daily indices that are then correlated with total solar irradiance (TSI) to yield a set of regression coefficients. This approach allows us to model the TSI with a correlation of better than 0.96 for the period 1996 to 2007. These regression coefficients applied to classified pixels on the observed solar surface allow the construction of images of the Sun as it would be seen by TSI measuring instruments like the Solar Bolometric Imager recently flown by Foukal et al. ( Astrophys. J. 611, L57, 2004). As a consequence of the very high correlation we achieve in reproducing the TSI record, our approach holds out the possibility of creating an on-going, accurate, independent estimate of TSI variations from ground-based observations which could be used to compare, and identify the sources of disagreement among, TSI observations from the various satellite instruments and to fill in gaps in the satellite record. Further, our spatially-resolved images should assist in characterizing the particular solar surface regions associated with TSI variations. Also, since the particular set of MWO data on which this analysis is based is available on a daily basis back to at least 1985, and on an intermittent basis before then, it will be possible to estimate the TSI emission due to identified solar surface features at several solar minima to constrain the role surface magnetic effects have on long-term trends in solar energy output.”
As you can see, you are several years behind the curve on this.
The major difference between PMOd and ACRIM composite is during the ACRIM gap
Since I, Dora Preminger, and Wang don’t use PMOD that straw man is irrelevant. So you should not waste everybody’s time harping on that. Yet ACRIM leaves 34% [=100-66] unexplained, while for PMOD the number is 17%, so PMOD is twice as good as ACRIM. But none is as good as TIM with only 8% unaccounted for [which is within the stated uncertainty of the stability, so might even by 0%].
No, Leif, TSI increased from 1980 to 2000 as I said.
The difference between you and I is that I provide evidence to back up what I say. Here is the ACRIM data: http://www.leif.org/research/ACRIM-TSI.png The pink squares show the old record [the one you worked with] while the blue symbols shows the latest adjustments to the published data. It should be plain that the blue symbols show that 2000 is lower than 1980. The green line is the overall trend which is downwards, in spite of the temperature trend for 1979 to the present which is upwards. But again, that doesn’t matter because ACRIM has severe uncertainty.
Don’t you see that you do not know much about these things while my partecipation to the conference woud be much appreciated?
On the contrary, I have to educate you on even the most trivial points and continuously point out your errors and circular reasonings. Let me tell you that my analysis of TIM showed that their correction for the varying solar distance was incomplete [they fixed the error in going to version 9 of the software] and that I discovered the keyhole problem in PMOD. I don’t think [as I have said repeatedly] that you’ll bring anything worthwhile, but you can try your luck with the organizers.

December 21, 2011 7:07 am

Leif, you use a lot of modelling and refuse to look at the data.
Let us look at your own figure
http://wattsupwiththat.com/2011/11/10/aurora-borealis-and-surface-temperature-cycles-linked/
Don’t you see the increaese in the minima from 1986 to 1996 and the decrease from 1996 to 2008?
Look at your green line. In 1996 it almost coincides with the solar minima, while in 1986 the green line is almost at the middle of the cycle. This means that TSI was on average lower during the period 1980-1990 than during the period 1990-2000, the period 1990-2000 was higher than the period 2000-now, and it appears that the period 1980-1990 was sligtly lower than the period 2000-now.
Possible that you are so blind?
Moreover, you are so confused about ACRIM, PMOD and TIM that you do not even understand the differences. TIM is too short for a multidecadal analysis of the TSI trending, for example. This trendig can only be studied with the ACRIM and PMOD composites and the difference between the two in during the ACRIM gap when PMOD alters the available NImbus data in a wa that I proved to be wrong.
You will mislead the Japanises with your refusal to be honest and objective. The best that you can do is to bring me there.

December 21, 2011 8:18 am

Leif,
you are seriously misleading the scientific community and the society with your unfair, ideological and obtuse understanding of reality.
As I have explained to you again and again your model does not explain anything and runs against the direct TSI measurements. In the history of science models like yours have always being find, before or later, severely misleading and based on naive assumptions.
“Why cherry pick 1980. ACRIM has data for 1979 too.”
First, ACRIM does not have data before 1980.
Those data are from Nimbus and may be partially corrupted because of the early degradation problem.
Second, you need to measure a cycle from, for example, solar maxima to solar maxima, not from where you wish to where you wish.
You just need to read my papers were I discuss both ACRIM and PMOD implications on climate.

They don’t explain anything because there is no effect to explain.
Those data are from Nimbus and may be partially corrupted because of the early degradation problem.
Yet they are part of the ACRIM composite, but I’ll accept that that composite has problems.
Second, you need to measure a cycle from, for example, solar maxima to solar maxima, not from where you wish to where you wish.
You didn’t yourself. And measuring on a faulty data series is not helpful to begin with.
You just need to read my papers were I discuss both ACRIM and PMOD implications on climate.
Those papers are not any good to begin with. The main issue is the errors in ACRIM. Those are clear starting in 1996 and the PMOD composite before that does not enter the equation. There is no difference between the minima in 1996 and 2008, so if ACRIM finds one, ACRIM is wrong. Accept that.

The scientific community is perfectly capable of deciding for itself what is wheat and what is chaff. One way the community expresses its appreciation and acceptance is by asking scientists to deliver keynote, invited, or solicited papers at scientific symposia and meetings [i.e. excluding activist and propaganda meetings, such as Heartland and the like]. Since I started this particular line of research in 2002 I have given 27 such papers [2.7 per year on average] (how many have you been invited to give?).

December 21, 2011 12:06 pm

“There is no difference between the minima in 1996 and 2008, so if ACRIM finds one, ACRIM is wrong. ”
Leif now you are getting quite lunatic again.
Your own TSI reconstruction shows a decreasing trending between the minima in 1996 and 2008.
You get
1995.5 1365.60
1996.5 1365.53
1997.5 1365.62
2007.5 1365.35
with a difference of about 0.2-0.3 W/m^2 between the two minima which is what ACRIM get, more or less.
Or perhaps, your arguing proves that your TSI reconstruction is based on a kind of Mike’s Nature Trick. You were getting with your model a totally flat TSI with no difference between the minima in 1996 and 2008, so in your TSI reconstruction since 1980 you have added not the data from your own model but you have attached to your model since 1980 a combination of the TSI composites to give the impression that your data approximately agree with the observations?
Tell the truth, Leif, are you using the famous Mike’s Nature Trick?

or a difference of 0.18. ACRIM has a difference of 0.383 or more than twice that. So your “what ACRIM get, more or less” must be seen for what it is: a blatant distortion or worse.
My reconstruction is admittedly crude. The much more accurate ones by Kopp and Lean, Chapman, Preminger, Krivova, and Ulrich show no differences. ACRIM is simply not good enough be base any conclusions about climate on, which makes moot all your papers on that.

At the time of my reconstruction [~2007] most scientists thought that the sun’s open flux was a proxy for the ‘background field’ which was also thought to be a proxy [at least in part] of TSI. So my reconstruction was a mixture of sunspot [i.e. facular] data and open flux [on the declining branch], as you can see here:
http://www.leif.org/research/HMF-TSI-Reconstruction.png
Since the HMF went down a lot at the end of SC23, so would TSI. Explaining the too low value for 2007.
This assumption was likely premature [if not wrong]. Improved measurements by SORCE/TIM showed that the open flux has little to do with TSI, rather [as also found by Ulrich and Chapman] the surface magnetic field [sunspots, faculae, network] is the determining factor [explaining 92% of the TSI variation]. This means that at all minima [when solar activity disappears] TSI would be the same. This would also apply to the Maunder Minimum and other Grand Minima.

These questions are actually important. That Nicola just trashes around driven by his agenda does not detract from the impact of resolution of the issues.

December 21, 2011 8:01 pm

Leif, I do not have any agenda.
I simply interpret the data that we have, and in my opinion the data despite their errors point toward a larger secular variability of the TSI and solar activity in general than your model suggest.
I am quite uncomfortable with your TSI model that shows a larger trending variability during the last two decades than during the period 1700-1990. In 2007 your TSI is below the minimum in 1700 and below the minima of the Dalton minima. This is very unlikely.
“At all minima TSI would be the same”. This is a too strong assumption in contraddiction with the Berillium records and numerous other records etc
http://en.wikipedia.org/wiki/File:Solar_Activity_Proxies.png
The data do not show that TSI minima are all the same. Very likely TSI presents a secular trending up to 1 W/m^2 .
You must interpret the MWP and LIA and current Warm period, which your solar model would not be able to interpret.

You are looking at the data set with the worst stability and the largest errors, so no wonder your results are unreliable.
I am quite uncomfortable with your TSI model that shows a larger trending variability during the last two decades than during the period 1700-1990. In 2007 your TSI is below the minimum in 1700 and below the minima of the Dalton minima. This is very unlikely.
I have explained that the 2007 point probably is in error, so that should make you more comfortable. And as you correctly pointed out earlier, but have forgotten now, two decades are two short to determine a trend. And it is really not my model. See e.g. Scrijver et al. http://www.leif.org/EOS/2011GL046658.pdf The issue is whether there are long-term trends over and above solar activity and none have been observed and on theoretical grounds none is expected.
The data do not show that TSI minima are all the same. Very likely TSI presents a secular trending up to 1 W/m^2 .
You do not specify over which time period,but I’ll assume you mean since the Maunder Minimum and are talking about the values at minimum. There is no evidence for such a trend at all. On the contrary, there is good evidence for no change at minima. If we assume that during the Maunder Minimum, TSI was stuck at its minimum value, then the average over the 70 years would be about 1 W/m2 lower than the average over the last 30 years [for which we have actual data]. This is 0.07% and would result in a temperature change of 1/4 of that or 0.02% which of T=289K would mean deltaT=0.05K. Even if you double that [as some would like to do because of unspecified ‘feedback’] you would still have only a 0.1K change. This I can live with.
“At all minima TSI would be the same”. This is a too strong assumption in contradiction with the Berylium records and numerous other records etc
The data leads us to that conclusion. The cosmic ray record has calibration problems which we’ll address at the ISSI workshop. As Webber and Higbie point out http://arxiv.org/ftp/arxiv/papers/1004/1004.2675.pdf “We have made other tests of the correspondence between the 10Be predictions and the ice core measurements which lead to the same conclusion, namely that other influences on the ice core measurements, as large as or larger than the production changes themselves, are occurring. These influences could be climatic or instrumentally based” and “Indeed this implies that more than 50% of the 10Be flux increase around, e.g., 1700 A.D., 1810 A.D. and 1895 A.D. is due to non-production related increases!”
One of the problems in the interpretation of the cosmic ray record is the concept of the ‘modulation potential’. This concept was defined in the 1960s under the assumption that the heliosphere was spherically symmetric, which today we know is invalid for low solar activity.
You must interpret the MWP and LIA and current Warm period, which your solar model would not be able to interpret.
Of course not, because it is a myth that the large changes during these periods are due to solar changes. But some people like to believe in comfortable myths. If you take a good look at slide 20 of http://www.leif.org/research/Does%20The%20Sun%20Vary%20Enough.pdf you can convince yourself that there is no correlation between Loehle’s temperature reconstruction and Steinhilber’s TSI reconstruction over the past 2000 years. You can find wiggles that correspond, but you can find as many that do not.

This may actually be a bad assumption, see e.g.
http://www.leif.org/EOS/2009GL038004-Berggren.pdf
“[16] In conclusion, our 10Be data from NGRIP provides a new archive that is strongly needed for identifying temporal and spatial variability of 10Be deposition over Greenland, thereby enabling more accurate solar activity reconstructions. Comparison over several centuries of our data with earlier data from Dye-3 indicates that despite the existence of local noise and some differences prior to the mid-16th century, the regional nature of the 10Be signal in ice cores is confirmed. The good long-term agreement between 10Be variations in both cores reflects a regional response to production and climate changes, but the disagreements in the earlier parts of the two records suggest that 10Be should be measured in ice cores from locations with non-complex ice flow regimes. 10 Be deposition is anti-correlated to solar activity over the 11-year Schwabe solar cycle, and correlated to neutron monitor data. Periodicity in 10 Be during the Maunder minimum reconfirms that the solar dynamo retains cyclic behavior even during grand solar minima. We observe that although recent 10Be flux in NGRIP is low, there is no indication of unusually high recent solar activity in relation to other parts of the investigated period.”

December 21, 2011 10:14 pm

Webber & Higbie [loc cit] concludes:
“When the first detailed 10Be measurements from polar ice cores were reported (e.g., Beer,
et al., 1990) there was the hope that this ice core data could provide a “monitor” of past solar activity as it effects cosmic ray intensities incident on the Earth, in much the same way as neutron monitors are used to monitor this solar activity in the modern era (Beer, 2000). This “concept” with its 1:1 correspondence between 10Be production and 10Be in ice cores, has since been used extensively to interpret historical 10Be ice core data in terms of changes in heliospheric conditions and their effect on cosmic ray intensities incident on the Earth. Our results show that, given our current understanding (or lack of it) of the correspondence between 10Be production, sunspot numbers and the 10Be observed in ice cores,this is really not a reliable “concept” to use for historical extrapolation. The sunspot number itself remains the best indicator of cyclic (11 year) solar activity after ~1700 A.D.”

Leif,
all your arguments are based on hypotheses that were considered unlikely yesterday and that tomorrow may be rejected as well. All your simplistic theories assume a constant core activity, for example. If the core varies by only 0.1 W/m^2 it would have huge effects on the convective zone.
About the agreemet between the climate record and the solar records you need to study my papers, the papers referenced there and my booklet:
http://scienceandpublicpolicy.org/images/stories/papers/originals/climate_change_cause.pdf
Read section 4 and look at figure 6 for the reconstruction of the climate patterns via all forcings since the MWP. You need also to give a look at page 32, 33, 34 and the other pages as well.
You analysis in your presentation is so so. It does not discuss the error in the proxy and you pick up only those proxy models that may presents problems without discussing the problems that they contain. For example, you do not understand that paleoclimatic reconstructions before 1000AD are very poor and need to be careful discussed. You just point to some disagreement without careful analysis and conclude that innumerable studies pointing toward a strong solar-climate interactions are miths
Your way of arguing is ideological and superficial, it is not a genuine way to study nature.
Your way of arguing is oversemplistic and you are just disregarding a huge litterature more or less as Mann’s Hochey Stick reconstruction disregarded a huge litterature about the existence of MWP and LIA. So, your model is unlikely.
Your model does not explain anything in the same way Mann’s Hochey Stick temperature reconstruction did not explain anything. It just mixed things randomly. It was just a tool for supporting the IPCC AGW theory, and that it is why it was promoted in our days often by abusing the peer review process for not letting alternative theories and models to be published and to develop. And this dishonesty and abuses exist also in solar physics, as you know very well.
Wait, and you will see that the things will change soon. In the history of science, simplistic theories that do not explain anything are always rejected before or later, do not worry.
“This is 0.07% and would result in a temperature change of 1/4 of that or 0.02% which of T=289K would mean deltaT=0.05K. ”
You do not understand how the cloud system work, don’t you? The real effect is 10 times that, at least. Read my paper with an open mind, the calculations are reported and are very clear. Read section 7 with an open mind and with some honesty.

Any variations in the core will be washed out on a time scale less than the diffusion time through the radiative interior.
About the agreemet between the climate record and the solar records you need to study my papers
Since all of those hangs on a flawed TSI, the ‘findings’ will not matter.
It does not discuss the error in the proxy
Nobody knows what the errors in any proxy are, and most people [incl. you] don’t know what the errors in direct measurements are. Only this year did Willson acknowledge some of the problems with ACRIM.
and you pick up only those proxy models that may presents problems without discussing the problems that they contain
My proxy stands on its own and does not rely on or use any other, so the problems other proxies may have are of little concern. I picked up ACRIM [is one on my list], what problems do you advocate ACRIM has, so it shouldn’t be on my list?
conclude that innumerable studies pointing toward a strong solar-climate interactions are myths
especially yours as it builds on problematic data and unfounded assumptions.
just disregarding a huge literature
most of which is junk
Your model does not explain anything
1: it is not my model, it is also that of Kopp, Lean, Chapman, Schrijver, etc
2: there is no need to explain as there is no large effect to be explained.
And this dishonesty and abuses exist also in solar physics, as you know very well.
Rigorous review is always needed to weed out sub-standard papers. The authors of such papers always cry foul, as you know very well.
simplistic theories that do not explain anything are always rejected before or later
As Mark Twain said: “it is not what you know that gets you into trouble, but what you know that ain’t” . And I have no theory on this. Observations show that TSI does not vary between minima, so any reconstruction that assumes that it does must be discarded. This was explained very clearly by Lean. I do not engage in theorizing on this, just in getting the data right.
“deltaT=0.05K. ”
The real effect is 10 times that at least

If so, the solar cycle effect every 11 years should be 1K at least, which is isn’t.
Read my paper with an open mind
No mind, no matter how open, can find the paper of value as it builds on discredited data. Your mind shouldn’t be so open that the brain falls out…

Nice example of curve fitting. You show strong AGW-effect(? or UHI?) after 1990.
The magnetic indices also follow TSI to an accuracy at least as good as your curve fitting,
e.g. http://www.leif.org/research/TSI-vs-HMF.png so you cannot separate the two.

December 22, 2011 11:58 am

Leif,
a scientific discussion requires the honesty of understanding and not twisting the position and the argument of an interlocutor. Unfortunately, you do not seem to have such an intellectual honesty and continuously twist things to mislead the readers of this blog. People who are really interested in understand things will read the relevant papers with an open mind.
Do not worry. Nobody, at the end, will believe your theory that does not explain anything.
You essentially claim that everybody that disagree with your position is wrong. And your position are based on a solar model that you yourself have declared to be simplistic. We will see.
Well, Leif, Merry Christmas!
Vukcevic, please send your paper to a scientific journal!

You use that word a lot. I take offense to being described as dishonest. Perhaps you should wash your mouth out with soap.

Goes both ways, methinks. Since you disagree with me, you must think I’m right, following your logic here.
And your position are based on a solar model that you yourself have declared to be simplistic.
Simple is not the same as simplistic. A simple argument shows the essential point. The simplicity comes from not assuming a secularly varying background for which there is no evidence. Kopp, Lean, Chapman, Schrijver et al seem to agree with me here. Actually, this plot shows the crux of the argument in a nutshell: http://www.leif.org/research/TSI-vs-HMF.png

Even when we see, I have a feeling that you will not change your [open] mind, but rather blame the data or the dishonest scientists that produce said data.

All data, except the CET of course, are from your files, so you should be able to reproduce it easily. The fact that TSI follows GMF indices is not disputed, it is also fact that the TSI and GMF indices (directly or Svensmark) are insufficient to swing the temperatures to excess of 1-1.5 degree C. There is also fact that the temperature on occasions disconnects from GMF as well as precedes it. The 10Be records (GISP, NGRIP & Dye data) are far too unreliable.
Only natural force capable of the effect is the NAP
http://www.vukcevic.talktalk.net/CET-NAP-SSN.htm
Post 1990 isn’t the AGW or the UHI, it is something for you scientists to work out why geomagnetic indices would drop down long before the last minimum.
It isn’t good science to either ignore or dismiss something which is not fully understood; to the contrary all unknowns should be pursued vigorously.

You should spread confusion by called it GMF, when you mean HMF.

any effect along those lines is even smaller than that of TSI, so can be disregarded.

Just shows that your ‘effect’ is spurious.

It is good science to dismiss spurious correlations. Scientists would follow up something that is solid or plausible, otherwise the matter is justifiable ignored.

Dr.S
Yes, meant the HMF not GMF (g&h are next to each other on the keyboard and the alphabet, perhaps not accidentally, Gaea and Helios) that was rather obvious. What is not obvious and what you should know about, but alas escapes you, it is the NAP. It is NOTHING to do with any of the solar or magnetic components (as far as the science understands it) despite degree of apparent correlation. As I said many times before it is the North Atlantic Ocean currents regulator.

You assumption is baseless. We simply do not have enough satellite data for determine it with precision. Is is not “simplicity” but “simplistic”. You are essentialy reconstructing TSI from sunspot number record that for physical reason is constrained in such a way to present the minima all close to a zero level.
In your own figure http://www.leif.org/research/TSI-vs-HMF.png
The only read data are TIM (green points) and do not agree at all with your or Dora’s model. The three green dots between 6 and 8 are clearly below your lines with slope 1. Tim would imply a much lower trend (with slope about 0.5 instead of 1) and/or a non linear relation between TSI and the observed B values that you are not taking into account in your model.
So your own figure disproves your model and Dora’s model at the same time!
A secular varying background is implicit in the ACRIM composite and other data from Be10 and C14 records. The secularly varying background can also be indirectly deduced from MWP, LIA and current warm period.
You need to disprove the existence of a secularly varying background, not start claiming that those people who assume its existence based on argument rooted on the data that we have, are all wrong simply because your model do not show such a secularly varying background for the simple reason that your model is constructed with the assumption that such secularly varying background does not exist. Yours is nothing but circular logic.
Your circular reasoning is based on the following steps:
1) let us first assume that the TSI secularly varying background does not exist.
2) let us build aTSI model based on the assumption #1. The model shows only a 11-year solar cycle almost perfectly equal to the sunspot number record with no significant rending among the minima.
3) The model built as in #2 does not show any significant secularly varying trend in the minima.
4) So, I, the Leif the Great, have proved that those who claim the existence of such a secular variation in TSI must be wrong. Thousands of studies that have shown a correlation between solar proxy and temperature records must be rejected because of Leif’s model.
Don’t you see your circular logic? You are starting with the assumption that the TSI secularly varying background does not exist!
As I said, you are not proving anything, but only stating your initial ssumptions!

The only real data are TIM (green points) and do not agree at all with your or Dora’s model.
Added ACRIM, and all TSI’s agree within their uncertainty. ACRIM is worst [of course], so its agreement could be totally spurious.
Tim would imply a much lower trend (with slope about 0.5 instead of 1) and/or a non linear relation between TSI and the observed B values that you are not taking into account in your model.
TIM is the best we have so a smaller slope [which is a bit dubious considering the small number of points] is just fine.
The secularly varying background can also be indirectly deduced from MWP, LIA and current warm period.
There is your circular reasoning again.
1) let us first assume that the TSI secularly varying background does not exist.
This is not an assumption, but is deduced from the data we have. E.g. http://www.leif.org/research/GC31B-0351-F2007.pdf and http://www.leif.org/EOS/2010GL045777.pdf
2) let us build aTSI model based on the assumption #1.
Building on the data presented above we build a model based on sunspot number only, because the data shows that only the surface magnetic fields contribute to TSI [92%]
3) The model built as in #2 does not show any significant secularly varying trend in the minima.
Because there isn’t any.
4) So, I, the Leif the Great, have proved that those who claim the existence of such a secular variation in TSI must be wrong. Thousands of studies that have shown a correlation between solar proxy and temperature records must be rejected because of Leif’s model.
You got it, finally!
As Hoyt & Schatten in their book ‘The role of the Sun in Climate Change’ has this to say about the thousands of papers: “Unfortunately, none of these studies is definitive in either proving or disproving the sun/climate connection”…”furthermore, many papers demonstrate poor statistical analysis, are too enthusiastic in their conclusions, or are repetitive”. Recognizing yourself here?

December 23, 2011 5:56 am

Leif,
Hoyt and Schatten do not agree with you in anything. They clearly believe in a secular TSI trending.
You are very good in twisting and distorting the work of everybody for your purpose, don’t you?
Hoyt and Schatten were simply saying that the secular trending of the TSI is uncertain, not that it does not exist and that it does not agree with the secular trending of the temperature.
Moreover, Hoyt has several times wrote me and appreciated my work.
In this figure you can see Hoyt and Schatten’s TSI model against the temperature reconstruction
and the matching is good enougth
http://wattsupwiththat.files.wordpress.com/2011/06/sunspot_demise_fig4.png
This is a comparison among all proposed TSI model and your model is by far the flattest one
http://rankexploits.com/musings/wp-content/uploads/2011/06/FancierColors.png
You model is nothing but the sunspot number record linearly recalibrated into TSI irradiance units W/m^2, which is extremely unlikely
You are essentially using a function very similar to the type:
Leif’s TSI= constant_1 * sunspotnumber + constant_2

Hoyt does surely. Schatten not.

Of course, as it must be, because there is no secular trend. Cf. http://www.leif.org/EOS/2011GL046658.pdf “[24] If the 2008–2009 solar magnetic activity is indeed similar to the Maunder Minimum level as we argue here, then it would appear that drivers other than TSI dominate Earth’s long‐term climate change.” You should nor call these ‘models’ as they are ‘reconstructions’.
You model is nothing but the sunspot number record linearly recalibrated into TSI irradiance units W/m^2. You are essentially using a function very similar to the type:
Leif’s TSI= constant_1 * sunspotnumber + constant_2

Precisely, as that follows from the fact that TSI is 92% described by surface magnetic fields [ “The sunspot and faculae model accounts for 92% of the irradiance variance that TIM observes” http://www.leif.org/EOS/2010GL045777.pdf ], of which the sunspot number is a reasonably good proxy: http://www.leif.org/research/TSI-vs-SSN.png
