From: Ryan N. Maue’s 2010 Global Tropical Cyclone Activity Update
Figure: Global and Northern Hemisphere Accumulated Cyclone Energy: 24 month running sum through July 31, 2010. Note that the year indicated represents the value of ACE through the previous 24-months for the Northern Hemisphere (bottom line/gray boxes) and the entire global (top line/lime green boxes). The area in between represents the Southern Hemisphere total ACE.
Note: Southern Hemisphere tropical cyclone data is spotty prior to the introduction of reliable satellite monitoring, thus the ACE represented at the beginning of the 1980s is likely underestimated due to missing data. Thus, it is possible that the current global collapse in TC ACE is comparable to lows experienced prior to 30-years ago…
Global TC Activity remains at 30-year lows at least — The last 24-months of ACE at 1090 represents a decrease from the previous months and a return to the levels of September 2009.
Since Hurricane Katrina (August 2005) and the publication of high-profile papers in Nature and Science, global tropical cyclone ACE has collapsed in half. This continues the now 4-consecutive years global crash in tropical cyclone activity. While the Atlantic on average makes up about 10% of the global, yearly hurricane activity, the other 90% deserves attention and has been significantly depressed since 2007. See Figure below.
Northern Hemisphere year-to-date ACE is nearing 50% below normal. The Western North Pacific is at 17% of normal (or the past 30-year average).

Steve Goddard writes:
Everyone in the hurricane forecast business predicted a big season this year. NOAA reaffirmed their position this week, as reported on WUWT.
One of the main reasons cited for the forecasts was “record high Atlantic SSTs.” So let’s look at the SST anomalies in the region between the Cape Verde Islands and the US. That is the normal hurricane formation track.
SSTs have plummeted and are now not much above normal. Compare SST anomalies vs those in late May. The hurricane breeding ground has not kept it’s unusual warmth.
Has this affected hurricane formation? Circumstantial evidence suggests yes. Hurricane numbers are average , and ACE is well below average.
http://www.weatherstreet.com/hurricane/2010/named-storms-climatology.gif
That’s going to be embarrassing for NOAA, half their predicted low number! What was Dr. Hansimian’s prediction?
Hurricanes are down and that’s good news. Joe Bastardi still thinks there could be a strong one to come this year.

I think this information, and it’s ramifications for AGW, should be added to the “Our Climate” app.
The William Gray Forecast, recently updated:
http://hurricane.atmos.colostate.edu/Forecasts/
SG: “Everyone in the hurricane forecast business predicted a big season this year. ”
Did they?
“NOAA’s 2010 Eastern Pacific Hurricane Season Outlook indicates a 75% chance of a below-normal season, a 20% chance of a near-normal season, and a 5% chance of an above normal season.”
http://www.cpc.noaa.gov/products/Epac_hurr/Epac_hurricane.html
The change over from El Nino to La Nina are usually reasonably above average years for hurricane activity in the Atlantic basin.
This year, shear still appears to be a problem with the presence of TUTTs (tropical upper tropospheric troughs) but as JB says, they will be lifting out soon, the Azore and Bermuda highs will solidify and the Cape Verde breeding ground will start to produce.
You can follow along with Mark Sudduth at:
http://www.hurricanetrack.com
Don’t forget that following the AGW crowd’s modus operandi of covering all bases NASA did claim that global warming would reduce the number of hurricanes.
Global warming makes hurricanes stronger and weaker. More common and less common. Sometimes global warming makes them unchanged.
People used to revere gods – now they worship CO2 and government scientists. Zeus vs. Hansen.
Has NOAA ever predicted a low hurricane season?
Dr. Mann of Penn State predicted 23 named storms. Dr. Gray of CSU team predicted 18. Through today we have had 3. Much ground to cover in the next 117 days. The problem is one of speed. Cape Verde waves only come off the continent of Africa about once every 3 to 4 days. There will be less than 40 of these waves in the rest of the season. And of these less than 40 waves, only 10% to 15% are normally productive ie grow into tropical cyclones. This engine just doesn’t have the time or band width to get the job done. Its not a travesty, unless you are rooting for heat transfer to the North.
9 August. It is still early.
Also, the SST area that shows below normal per the map Steve shows is not really the tropical cyclone breeding ground for the North Atlantic.
The breeding ground i s further south, between the Lesser Antilles and Cape Verde, and it shows a positively warm anomaly.
The cooler area to the north doesn’t help, of course. But I would like to know how such a cold anomaly could appear so fast? Is it a giant upwelling?
The latest NOAA weekly SST anomaly map (OK the latest I could pull up which is the last week of July), doesn’t show any such cold anomaly, or anything close:
http://www.emc.ncep.noaa.gov/research/cmb/sst_analysis/images/wkanomv2.png
Neither does the map showing the last month:
http://www.emc.ncep.noaa.gov/research/cmb/sst_analysis/images/monanomv2.png
Something ain’t right here. What gives?
What is the good map showing SSTs here?

I didn’t say the SSTs were below normal. Where did you get that from?
So, not too many hurricanes for the media to get excited about, so they are having to fall back on a few other (carefully cherry picked) ClimateNotWeather events. Floods in Pakistan, Moscow Burning, The Monster Ice Cube. The WeatherNotClimate cold events in South America, like the severe European winter 2009/10 and the Mongolian Dzud can be ignored or forgotten.
As Richard North puts it:-
“…..we get plenty of coverage about the Russian heatwave, but got very little about the coldest winter in 130 years … in Russia. Thus, the whole subject is wide open to cherry-picking, which distorts even accurate reports of isolated events. Without an appreciation of the whole picture, and a longer-term perspective, there is nothing that can be properly inferred from these events.
The real news, therefore, is not of climate, but of human tragedy and suffering. That we can do something about, and a fraction of the billions spent on “climate change” would go a long way to reducing the impact.
But as long as we are in the grip of the climate zealots, those being killed by the weather now are less important that the lucrative funding opportunities arising from predicting future disasters. How perverse it is that potential deaths in the future get more money than real deaths now – a sad reflection on human priorities.”
http://eureferendum.blogspot.com/2010/08/perverse-set-of-priorities.html
I have said it before and I’ll say it again;
That is an effect from the timing of the synod conjunctions with the outer planets, Saturn on March the 22nd 2010, brought in a nice load of heavy rain, tornadoes and flash floods globally.
Now with no other outer planet heliocentric conjunction until they are all clumped together August 20th till September 24th, the additional power inducted into the tropical storm engine has been lacking. Leaving us with just the lunar declinational tidal meridional pulses that brought us Bonnie and Colin as pulses of tropical moisture (that formed off of the center of circulation) with out the ion energy content to drive the peak precipitation that drives them into cat 2 – cat 5 storms.
They (the bigger storms) are waiting till the ionic discharge of the global atmosphere that happens post synod conjunctions, expect the stronger storms to start on the 20th of August 2010, and run to 28th of August, 2010, and start up again September 21st and run through end of the month, with some after thoughts due to continued further discharges, coinciding with the lunar declinational culmination angle peaks, both North and South.
The lack of severe Tropical storms is a combination of effects of the slow solar cycle activity, with the descending culmination angle of the lunar declination, and the outer planets Saturn /Mars this last spring, and Neptune, Uranus, Jupiter, and Venus all clumped into the fall this year.
The huge clumps of strong hurricanes seen in 2005 will not be back as long as the outer planets Neptune and Uranus are drifting apart and progressing into the fall, instead we will be experiencing their effects as more East coast and European snow storms of increased intensity.
Given also that there will be no outer planet assisted forced intrusions of warm moist tropical air masses, during the next several Northern winters, expect cold and blustery to be the norm for a while (about 15 to 20 more years.) You will see your breath, but not feel the CO2?
As soon as I can get back to Phoenix, where I have high speed internet, available programmers and tech support, I will be plotting ACE values by lunar declination, and outer planet synod conjunctions to form a visual format in the search for correlations and to assist in formulation of causation mechanisms.

I’m too busy drafting stock exchange announcements and editing the latest AIG News issue to get too involved in this suggestion, but it might be useful for one of the folks reading here to plot sunspot numbers versus cyclone activity re above top graph over the period good data exists.
The physics behind this is based on the idea that cyclones/hurricanes etc could be physical phenomena within the gaseous film coating the earth as a result of electric currents entering in/out of the Earth’s equatorial regions via the Van Allen belts.
If the solar variation, as indicated by the proxy of sunspots, is due to fluctuating electric currents entering into the solar system, then peturbations within the system should show some correlation with the sunspots and a time lag as well.
So low solar activity as proxied by sunspots should show correlation with tropical cyclones/hurricane activity/intensity if the latter are due to, hitherto poorly understood, electro dynamics of the earth system. Both phenomena are effects of a common underling cause.
Just a thought.

There appears to be a trap that everyone is falling into which is pattern matching within the period of our own experience e.g. CAGW’s ‘since records began’ normally means ‘since satellite records began’. Or within the period of historic measurements that apply e.g. hurricane records going back 100 years or so. Even these hurricane recordings are limited prior to satellites and population of the shores of the southern US States.
We may now be moving into a climate shift in the chaotic ocean/atmosphere system and reliance on ‘the Azores and Bermuda highs’ solidifying as they did in the past may be unwise. The jet-stream does not appear to be behaving in a way that imbues confidence in the future weather patterns just repeating what they have done over the last fifty years or even a century.

First Global Connection Between Earth And Space Weather Found
09.12.06 http://www.nasa.gov/centers/goddard/news/topstory/2006/space_weather_link.html
Weather on Earth has a surprising connection to space weather occurring high in the electrically-charged upper atmosphere, known as the ionosphere, according to new results from NASA satellites.
What this means is, the earth acting as a CATHODE it is subjected to a variable current from the Sun, which when strong makes the jet stream get closer to the poles, while when low jet streams will migrate equator ward.

H2O varies by by tens of thousands ppm from one day to the next. Sometimes from one minute to the next.
When ever I read a climate related paper or article that drifts from trying to resolve the intricate relationships of our climate, into trying to predict events in other hugely complex disciplines (like hurricane forecasts, hydrology, or agricultural production) – my interest wanes very quickly.
No one wishes bad things to happen due to tropical storms, but here in W MD, significant late-summer, early-fall precip often comes from such systems (and can save crops & pastures to some extent). Without them developing, it is often bone-dry here during this period — last year was the perfect example.
An easterly QBO reduces hurricane numbers, but not intensity.
Saharan dust storms limit Atlantic cyclone activity;
http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=44758
The big changes from one year to the next, are largely due to whether a given year has warming spurts in the right months, to provide conditions that are condusive to cyclone formation.
This Autumn has some very strong solar triggers for cyclone activity occurring right at peak season around the equinox, so I am expecting some intense events this fall.
My longest look-back period (1831) suggests a large Caribbean hit in September.
Mother Nature has a quirky sense of humor. Even when she’s trending down, she can knock you for a loop on occasion. Low activity vis-a-vis previous years does not mean no activity. Keep yer storm shutters handy and yer gas tank full!

I didn’t say the SSTs were below normal. Where did you get that from?
===============================
I misread. Sorry about that. You did say “not much above normal”. That first map, though, was confusing to look at. It shows a large area which, now that I look at it must be an upwelling from Colin.
Bastardi posts this on his Pro Accuweather blog this AM:
“GLOBAL ACE AT RECORD LOW, BUT IS A RECORD HIGH ATLANTIC ACE ON THE WAY IN SEP OR OCT.”
“Interesting question. The GFS now is seeing what is coming… not in the details, but in the overall pattern with 2, arguably 3 storms on it on day 16. Dont trust the positions, but trust the idea this is going to roar to life. Keep in mind, the southeast Pacific basin, which should be well below normal the rest of the season, had a record high June burst. This was because it warms first and the N American continent was cool enough to focus upward motion there while the water was warmer relative to averages. What do you think is going to happen once cool air gets into the pattern, or the land based normals fall. That is when the MJO will be able to crank well into the octants associated with real trouble bursting and I fully expect that to be the case. You can see the shift in the anomaly pattern about to occur.”
I trust that an independent body names the storms, otherwise it’s Col. Sanders looking after our chickens. I recall in 2006 they were desperately reporting water spouts and light rain.
The earth is a heat engine. Hurricanes are driven by differences in temperature between the equatorial Atlantic and the North Atlantic.
The North Atlantic has well above normal SSTs, so it kinda makes sense that this season might not be quite as intense as the experts are forecasting.

Your excellent article shows that astrology has now a justification, which is invalid if only considered a “flintstones’ universe” where only gravity among “heaven pebbles” works.
For hurricane forecasts, the pre-and post-1975 stats are most important for the AGW hypotheses – those of at least the pre- and post-1988, when we were told of impending doom. Do you have a graph of those?

=========================================
I see what you are driving at.
But I think what Gray, Bastardi, NOAA, FSU and others are driving at is the above normal SST which provide the fuel for the storms.
The cooling in the Pacific, due to the cold PDO and the reversal of El Nino, displaces the area of upward motion to the Atlantic (and westward to the Indian Ocean region, hence the horrific floods there).
So abnormally above normal SSTs for the North Atlantic (from the warm AMO) + upward motion + the removal of the tropical upper tropospheric troughs and voila.
You can certainly see from the North Atlantic Water Vapor Loop the Cape Verde train at least trying to get organized, and a couple of anticyclonic spins above a couple of the waves in lower left hand of picture, hinting of some high pressure in the upper levels and a developing Cape Verde season.

This link is the result of 30 years of my work, so yes and yes, there is other supporting research quoted on the site, the daily forecasts presented on the National and local pages were forecast 30 months ago, and continue till January of 2014.
This is an analog forecast method very similar to what Ulric Lyons and Piers Corbin use with look backs as they call them, but with out the solar activity they have added in. The outer planet influences don’t show up in the daily forecasts, because they are out of phase with the repeating inner planet and lunar declinational patterns. This is a beta product and has been very helpful in the further development of concepts to include the solar and outer planet influences by deriving algorithms, to be added to the program to increase the accuracy of future development releases .

They are all intercorrelated, whether climate or waether, with none of the ASSUMED CAUSAL independent variables known for the future so time series models, estimates and conjectures are used in all cases. I read to learn but have little faith in any of the theories or predictions of what will happen next. It gets interesting when predictions start to come true, which rarely occurs and unless they continue to come true can be considered coincidence.

My understanding is that La Nina in the presence of a warm equatorial Atlantic produces the temperature/pressure differences and wind shear that spawn hurricanes into the Gulf. Otherwise, during El Nino and a warm Atlantic the hurricanes become northeasters, hitting as far north as Main, especially in the case of negative Arctic Oscillations, which throws cold air South, essentially canceling the calming affect of El Nino’s and setting up the necessary wind shear.

Over the years I have spent up to 25% of my hourly wages working as a production CNC machinist on this project, I have had help from my daughter who does the web site for me, and a programmer she works with freelance, did the map generation data automation process, at a reduced rate as a favor.
The link below is one of the better links I use for looking at global SST’s. Still pretty good positive anomalies across the Tropical Atlantic I’m not so sure I agree with the above analysis. Granted SST’s have cooled compared to the record setting April through June, but they are still plenty warm for increased tropical activity. The biggest hindrance so far has been the elevated vertical wind shear that has plagued the season so far. The second half of August through the end of October should be very busy though. Take a year like 2007 (our last La Nina) where there were only 3 named storms through the first week of August. From August 13th through the end of the season and even into December there were 12 more named storms.
Bottom line, there is still plenty of time for an above normal season.

CNC on an Aerology project [defined as a branch of meteorology involving observation and research of the atmosphere by means of balloons, radiosondes, etc] implies Real World [not heat Island] data.
I noticed the reference to NOAA TD3200 cooperative summary data on your “About” page but my fingers are crossed the baseline is more.
PS If the baseline produces an accurate display of past events, can the program identify potentially false readings in other forecast models and, if so, within what level of accuracy?

The maps produced are set to use medium smoothing in the nearest neighbor method of producing the temperature contour maps with 32 data points selected for the averaging, with 10 degree contour line increments.
When I processed the maps with 8 data points, (minimum smoothing) and 1 degree increment contour lines there appears circles of the heat islands, and cooler regions around large lakes. The net effect was way too busy for easy public consumption, so I went to medium smoothing, but could show local temp extremes in the past data as well as the composite. I don’t know about checking other forecast techniques, I am still trying to work the outer planet influence bugs out of this one.
When I look at the cyclone data and do an eyeball Fourier decomposition I get a strong component at about 6 -11 year periodicity. Didn’t anyone else notice this!? Doesn’t this say the sun drives just about everything?
savethesharks says: “Also, the SST area that shows below normal per the map Steve shows is not really the tropical cyclone breeding ground for the North Atlantic.”
The SSTs for the tropical North Atlantic are far from normal on the map that Steve Goddard cropped. Check the scale on it. Unisys uses light blues from -0.5 to +1.0, so they can be misleading. Tropical Atlantic SST anomalies reached a new high this year.

Some of that is from the 2009/10 El Nino.
And some of that high results from the upward shift in the South Atlantic SST anomalies in 2009/10 after almost fifteen years of being flat:

Recall that the heat is transported from the high latitudes to the tropics in the South Atlantic (the only ocean basin that works that way), and then into the North Atlantic.
That shift in the South Atlantic SST anomalies is discussed in this post:

Pete says: “The link below is one of the better links I use for looking at global SST’s.”
The NOAA/NESDIS SST data you linked is prepared by NOAA’s Coral Reef Watch division. It’s biased by the use of only nighttime satellite data.
“Nighttime-only satellite SST observations are used to eliminate diel variation caused by solar heating at the sea surface (primarily at the “skin” interface, 10-20 um) during the day and to avoid contamination from solar glare. Compared with daytime SST and day-night blended SST, nighttime SST provides more conservative and stable estimate of thermal stress conducive to coral bleaching.”
Discussed that here:
http://bobtisdale.blogspot.com/2009/09/note-about-sst-anomaly-maps.html
But yes, as I noted to savethesharks above, tropical Atlantic SST anomalies are well above normal:

So anomalies moved northwards.
The recent near two-degree rise (in 12 months) in tropical Atlantic SST anomalies is interesting. A series of higher highs are plainly visible on Bob’s chart. One would think that the ACE Index would be off the charts now if there was a strong correlation. Instead, one can see a series of lower highs and lower lows (from 1990 until present). Not sure what to make of this.
I apologize. I meant the question Richard Holle, who is funding your research–Exxon or BP? to be tongue-in-cheek. However, in today’s world of nonsensical or irrelevant comments coming from the AGW community, I should have realized that any comment/question, no matter how silly, must be taken seriously by us skeptics because it could have been asked by a warmist.

Reply; I got it, but there are lots of trolls, and newbies coming in here all the time, and I am sure lots of constant lurkers, are the majority of viewers.
I think it best to keep things as clearly stated as possible, and not leave oneself open to partial quote mining, just to keep the clutter down so the message is clearer.

Venison is awful. Elk is a delicacy.

Depends what they graze on—willow buds good, coniferous buds bad. I prefer moose and caribou. Not many around my neighbourhood, tho’.
Depends on if they are shot dead or run two miles as well.

If anyone wins the moose lottery for whatever management unit it is that includes Mt Cardigan in New Hampshire, look me up – we have moose and I don’t hunt.
Well, NorthWest Pacific (NWP) inactivity is the background of this year’s worldwide inactivity. In the case of NWP, exceptionally strong sub-tropical ringe (STR) have hindered the formation of disturbance even in very low latitude ( because around 70-80% of NWP’s tropical cyclone are formed in monsoon trough, and super strong STR have make it inactivated ), resulting only 5 numbered storm ( max wind reached F6 ) by Joint Typhoon Warning Centre, three of them ( max wind reached F8 ) named by Japan Meteorological Agency, and only 2 have been considered reaching a typhoon strength when we are used to see around 5-8 typhoons already at this point of the season, deafening silence in NWP’s history.
One more point should be noted in NWP’s condition, the year following El Nino are supposed to have the STR weak and East of its normal position so more storms can form in Central North Pacific or the Eastern end of the NWP and we may see 01C or 02C, this year, the STR is so strong that there is neither a tropical cyclone formed in Central North Pacific, nor a single tropical cyclone formed East of 145E.
Results followed, NWP tropical cyclone season have been bored to death not because every cyclone end its life on the sea, but simply no cyclone at all thanks to a STR strength unseen in at least 20 years.
One more point to note, NWP is the most important tropical cyclone formation basin in the world, it alone account for 30% of world’s activity, so if this site have been weak in capturing NWP’s condition and mostly focused on the area around USA, I am very much afraid that WUWT might not be global enough in this particular issue.
