Not so hot – ocean temperatures around the USA are not anywhere near record levels

While there’s wailing and gnashing of teeth over the US CONUS surface temperature being the “hottest ever” a cursory review of the sea surface temperatures in U.S.Coastal waters shows no cause for alarm, as they aren’t even close to record levels. It’s just one more reason to suspect that UHI and thermometer siting issues are a major forcing component of the surface temperature record.  – Anthony

Are July 2012 Sea Surface Temperatures for U.S. Coastal Waters Also At Record Levels?

Guest post by Bob Tisdale

The map in Figure 1 shows the July 2012 sea surface temperature anomalies, based on NOAA’s ERSST.v3b dataset, for the coordinates of 24N-50N, 130W-65W.

Figure 1

We’ll use those coordinates for the sea surface temperatures (not anomalies) of the U.S. Coastal Waters in the following two graphs. Figure 2 illustrates the July sea surface temperatures for those coordinates from 1854 to 2012, and Figure 3 shows the annual (ending in July) sea surface temperatures for U.S. Coastal Waters from 1855 to 2012. I’ve also plotted the July 2012 value in Figure 2 and the value for the period ending in July 2012 in Figure 3 to simplify your task of comparing the most recent temperatures to the earlier values.

Figure 2

HHHHHHHHHHH

Figure 3

The sea surface temperatures of U.S. Coastal Waters are nowhere close to being at record levels for the month of July 2012 or the 12-month period ending in July 2012. I’ll let you decide (speculate about) what that means with respect to the claims of unprecedented U.S. land surface temperatures in July 2012.

My priority is finishing my book about ENSO and its multiyear aftereffects. I’ve only got a few more chapters to write and then I’m done with the first draft of Who Turned on the Heat? The Unsuspected Global Warming Culprit, El Niño Southern Oscillation. Then I have to go back and read the 500+ pages to see what I wrote.

Anthony, Bob,
I can’t help but think that the “unprecedented” temperatures and “record breaking” drought are related, but not in the sense that the alarmists would have us believe. Because of the drought, the actual heat content of the air is likely to be low despite the “unprecedented” temperatures. This report on the coastal SST’s seems to corroborate that we aren’t seeing much heat build up despite the temperature “extremes”.

Well, one might expect water and land temps to have some correlation? The mid west coast seems cooler in general this summer, though perhaps more variable – some very hot days (not by mid west coast standards that is – easterners and southerners put down your coffee cup before I say that hereabouts 30C is a hot day ;-).
OTOH, the oceanography center on the coast of OR told us that the ocean water nearby is colder in summer than

Mr, Watts,
Up with that is the NASA folks now, just saw on yahoo’s open page a new NWS photo put together of a huge low center storm up in the artic just now. Ya, they seem to be going to use that storm as a “sea ice killer”. A quote from a NWS guy,,”Very strong storm” it may cause damage to the ice up there due to the “current thin condition of the ice” this could be a problem.
You might see what they are up to, as when they do this they use things like yahoo and google main pages to make it look like real news.

How can we have any confidence with temperature data points over 30 years old? There would have been very few stations and what depths with what current in the place at that time. Just the California seas change season by season depending on the Japanese current and then the el nino/la nina effects which are not predictable.
No one can convince me that the 1800 and early 1900 have any accuracy during the early days they had the devil of a time just using the Gulf stream to aid shipping . . so How do they address these issues?

Well, obviously the seas are doing their own thing(s) in line with not-always predictable patterns, depending on current and weather but I find it interesting to note that in both graphs 2 and 3 the temp. of your seas at 1895 was exactly the same as 1995. This is the 100 year cycle that I estimated from the maximum temps. (parabolic plot)
So here is an idea for your book: plot the maxima – it seems for reasons that apparently no one can explain I am the only one plotting them.

(I could just stop writing right there, and leave you with a remark no more helpful than your’s, but that’s just not me.)
At decadal time scales natural variability will dominate long term trends. Atmosphere over land will heat up and cool off much faster than sea surface does, and with far greater variability due to the tiny heat capacity of air versus the ocean. Over the long term however, the ocean with a mass 1400 times that of the atmosphere dictates just how far atmospheric temps over land can stray. The ocean is like a large adult dragging a tiny child by one hand through the mall. It is the screaming, crying, and kicking of the child that we notice, but these have little to do with the direction of the child’s motion.

Anthony asked, “Is the Great Lakes data masked out in this analysis?”
Nope. I had the map-making feature at the KNMI Climate Explorer on the “Contour” setting because it produces a nicer looking image. Here’s the same map using the “Grid” setting. Except for a chunk of Lake Michican, ERSST.v3b appears to capture the Great Lakes.
http://i49.tinypic.com/w7kiuv.jpg
Geert Jan van Oldenborgh of KNMI explained the difference between the “contour” and “grid” settings to me a couple of years ago, but I don’t recall the specifics. Based on his email, I use the “grid” setting when I present which grids have data. Phrased another way, I use it whan I want to show how sparse the source data is.

I think there is a back story developing at the ENSO prediction page. I have been following the three combined predictions, dymanical, statistical, and what they call the “consensus” prediction model statistic. The consensus model prediction, over the year, has been getting closer and closer to the statistical model prediction. Have the majority of the dynamical models lost favor with the “consensus group”? Why? It should be noted that the majority of the dynamical ENSO models have a warming CO2-related fudge factor built in, probably ? from the days when scientists felt that CO2 would cause more frequent and more severe El Ninos.

I have wondered, “Is it really ‘warmer’ on CONUS (Continental US), or do we have more reporting sites?”

Think about it a second…
The flow into the Great Lakes as a collective whole comes from U.S. states
not totally within the “2012 Dought” area, but well within the region that’s
had temperatures elevated (not necessarily record highs) since June.
Increased regional land temps with moderate drain-off and increased surface
temps through insolation in shallower bodies of of water like Lake Erie yielding
higher than usual water tems just makes logical sense.
The same applies to the Eastern seaboard where the warmer drain-off from
non-drought states has yet to mix with the Atlantic waters and then head off to
the North.
The real drought and higher temperature region in the U.S. tends to
drain into the Missisppi river, so the reduced but warmer water flow has less
impact when finally mixed with the Gulf of Mexico waters.
See:
http://droughtmonitor.unl.edu/
For the recent (past 10 days) air and near-land ocean current flow around
the Atlantic seaboard see:
http://www.ssec.wisc.edu/data/comp/cmoll/cmoll.html
Things may change a bit for the “cool” waters off the west coast below central
California after the current temperature spike this weekend/next week.
“Not so hot” could be rephrased as “Just about right”.

In the paleoclimate discussion, La Nina (cold eastern Pacific) is believed to be the cause of US drought. Hoerling’s excellent discussion of past droughts (well before current interest) also emphasizes cold Pacific.

August 10, 2012 4:31 pm

Note the warm SSTs over the Atlantic downwind from the large US East conurbations, a reduced aerosol effect.
Not sure why Bob put East and West coast SSTs in the same graph. The oceanic influence will come from West coast (Pacific) waters, with some contribution from Gulf waters. East coast (Atlantic) waters will have no influence.
And West coast waters are unusually cool.

Arno Arrak
August 10, 2012 6:55 pm

Bob – Sea surface temperature in general has very little to do with continental interiors with the exception of the SST in the Eastern Equatorial Pacific. That is because the El Nino wave makes landfall there and spreads out. This warms the air above it, warm air rises, interferes with trade winds, mixes with prevailing westerlies, and thereby raises global air temperature. When that El Nino wave then falls back ocean level behind it drops by half a meter, cold water from below rises up behind it, westerlies are cooled, and a La Nina begins. It is ENSO that is globally a prime mover of temperature and its workings are laid bare in that part of the world.

After gridding the anomalies, bias corrections are applied to remove spurious trends caused by changes in ship deck heights and various unusual operational practices, and the data are smoothed to reduce noise.

Arno, those of us in the interior portions of West coast states, and states just to our East, readily feel the ocean’s influence. Analogue years, years that mimic current oceanic conditions, are used to forecast the next three months for agriculatural purposes. Both temperature and precipitation amounts and type from these analogue years help farmers and ranchers make all kinds of risky decisions, made less risky by the predilection of our zonal climates to follow what the ocean is telling them to do.

HenryP, you have done some excellent research! Measuring regression slopes often reveals underlying trends very clearly. I did something similar for UK rainfall. See http://www.thetruthaboutclimatechange.org/rainfall.html
My first graph simply shows the annual rainfall statistics. You will see that the overall change over the 241 year period is an almost insignificant +2%.
But my second graph plots regression slopes over each successive 50 year interval since 1770. This quite dramatically shows that the rates of change in rainfall (up and down) have reduced significantly in the last 50 years compared with earlier times.
The fact is that temperature, like rainfall and other climate variables, oscillates up and down by a few percent from decade to decade in a natural and un-alarming way. So…
1. Temperature data show a thoroughly un-alarming long term positive trend of 0.41degC per century. See http://www.thetruthaboutclimatechange.org/tempsworld.html
2. Rainfall data show an equally un-alarming long term positive trend of 2% per century, with a recent distinct reduction in extremes. 
Despite these facts, the climate alarmists apparently want to close down Western civilisation without any empirical data at all to back up their theories.

http://polistrasmill.blogspot.com/2012/08/christys-minimum-temp-hypothesis.html
Can’t really blame NCDC for using 1895; that’s when the Weather Bureau set up its telegraph observation network, so it’s the start of regular records for most of America. It’s not a deliberate fudging of timeline. But starting at 1895 skips half of the curve, so most records are heading mainly upward since then.

You need to study a subject, Arno, before you make general statements like that that have no basis in fact.
I believe you’ll find that about 85% of the variations in short-term and long-term land surface temperatures are in response to variations in sea surface temperatures. There are a multitude of observation-based and model-based studies about that subject. I’ve even written posts about it, using data to support my findings.
BTW, your descripton of an El Nino event’s impact on surface temperature fails to consider that the majority of El Nino events are central Pacific, not east Pacific El Nino.

“It would be instructive to actually look at the historical relationship between land temps and SST.”
You can do it by looking at the graph of the first temp plot. Remembering in a general way the warm and cool period of the last century – hot 30s -not so hot sea temps, cold 50s-60s hot sea temps but it seems that the sea lags the land by several years – probably decadal oscillations at work rather than lagging land heat.

During an El Nino, it’s the change in location of the primary place of convection (from the Pacific Warm Pool to the central and sometimes eastern equatorial Pacific) that causes the shift in the jet streams, which in turn cause warming in some places and cooling in others.

You’re not going to find a good correlation of US temperatures to surrounding sea surface temperatures.
One issue is that US temperatures are so variable – they can be +/- 5.0C on a monthly basis while sea surface temperatures never have that kind of variability.
I’ve tried dozens of different sea surface temperature metrics before and have not found any kind of good match. A simple one that is as good as any other is the AMO index covering most of the north Atlantic and it is not good enough in my opinion.
http://s10.postimage.org/o5h5k5iw9/CONUS_and_the_AMO_July2012.png
The prevailing wind patterns means that the North Pacific and the Tropical South Atlantic ocean should be influencing US temperatures but this is nothing to write home about either.

IIRC, the UAH dataset covers 82.5° N to 82.5° S. A fairly good chuck of the globe. Given that the Arctic is likely on the warm side while the Antarctic slightly on the cool side, it might underestimate the temps slightly. However, I don’t think it’s anything meaningful. In addition, Arctic temps in the summer are always consistent so for the June/July numbers it should be very accurate.

going from the end of that statement to the beginning:
On the one side of the arctic it is warming a bit: e.g. if you look at Norway, where a lot of condensation takes place, releasing energy,
but if you look on the other side, e.g. at Anchorage, the amount of cooling is frightening.
Check it up in my tables, http://www.letterdash.com/henryp/global-cooling-is-here
Indeed, as you seem to know and, as, until now, I suspected, in the antarctic I think the cooling down is even worse, but, strangely enough, I cannot find reliable original data showing me maxima, means and minima, from weather stations in the antarctic, to include in my tables….(I am more interested in maxima data then average temp.data)
Someone or some body is trying to hide that data. Help me if you can.
Looking at my own data, I think UAH is out by a bit. We are down by at least o.2K on earth since 2000.

“We now know that such solar minima correlate quite closely with colder-than-normal temperatures on Earth, but science has yet to ascertain exactly why. Solar maximums, on the other hand, have historically had little noteworthy impact on the Earth apart from extra-splendid auroral displays. But thanks to our modern, electrified, interconnected society these previously innocuous events could cause catastrophic economic and social damage in the coming decades.”

Bob – I did ignore the El Nino Modoki in the belief that they were not very common. Your statistics seem to prove that they are more common than I thought but it does not change the basic idea. CP El Nino happens when something blocks the El Nino wave before it has reached South America. The blockage forces the warm water of the El Nino wave to spread out on the surface which warms the atmosphere just as it does when it spreads out near the coast. As to the role of jet streams I have always regarded it as secondary to the main event

That big curve from 1860 down to 1920 and up to present agrees with the record of Armagh, presumably “non-continental” and non-air-conditioned.

The Armagh observatory is downwind (northwest) of Armagh town, where coal and peat (a very smoky fuel) were the main form of domestic heating until the 1970s. You can clearly see the warming trend resulting from phasing out these fuels post 1970s. Reduced aerosols/particulates = increased solar insolation.

Arno: Further to my comment above, your description of El Nino . . .

Arno’s explanation at 6:55 pm seems to implicate warm rising air as ‘interfering” with the trade winds – what that means I’m not sure. Does it mean causing them to weaken? But isn’t warm rising air a characteristic of the ITCZ? Then the ‘prevailing Westerlies’ are invoked to incorporate this warm air – but again, confusingly, the Westerlies would have to be moved from their normal position to do this. So it seems:
http://en.wikipedia.org/wiki/File:Map_prevailing_winds_on_earth.png
I’m not saying that warm surface waters never reach these higher latitudes but that would seem to be a tail on the end of El Nino, and not the primary driver that “raises global air temperature.” Maybe there is another un-invoked (un-named) process in Arno’s explanation that I’m not understanding.
Further:
Pamela Gray’s comment @ 9:19 is a direct reference to eastern Oregon and Washington State including that we have mountains between this region and the Pacific Ocean. “Analogue years” sometimes tell us to expect colder and drier winters, sometimes wetter and warmer ones, and so on. I haven’t a current link to this concept for North America but here is one for Western Australia with page 6 showing “five closest analogue years” for their 9 May 2012 report.

the UAH dataset covers 82.5° N to 82.5° S
With the circumference of Earth being about 40000 km, the distance from 82.5 to 90 would be 7.5/90 x 10000 = 830 km. So the area in the north NOT covered is pir^2 = 2.16 x 10^6 km2. So if we double this for the south, we get 4.32 x 10^6 km2. Dividing this by the area of the earth, 5.1 x 10^8 km2, we get about 0.85% NOT covered and 99.15% covered by UAH.

Jake says:
Because of the drought, the actual heat content of the air is likely to be low despite the “unprecedented” temperatures.

More appropriately, the “unprecidented” temperatures are likely because of the low heat capacity of the dry air. The lower the heat capacity, the higher the temp rise for a given input of heat.
La Nina causes drought in the southwest US. Drought in the southwest causes dry air in the southwest. Dry air in the southwest causes heat waves in the southwest. We are told that ‘global warming’ causes fewerand weaker La Ninas, so drought and heat waves in the southwest US should become less frequent/intense under ‘global warming’.
So, this is not what ‘global warming’ looks like.

Again, here’s ” weary ” of discussing with the people at WUWT but has no problem discussing with mindless trolls who don’t talk any sense.

it’s not that Mosh is not smart enough. He is smart. But he has definitely been stung ever since Anthony wrote the current surface stations record paper. From that time he has gone on a total antagonistic whining, moaning and sniping spree everywhere on the blogosphere about WUWT, totally negatively and with deliberate intention to hurt the reputation of WUWT and Anthony.
In that process, he’s got his head too much up his own a**e to realise that it is he who’s looking like a proper pillock.

Cannot get a rsquared better than 0.98 on the changes in degreesC/annum against time on that. If everyone continuously keeps looking at that, they will miss what is happening to our energy input. The rainfall data also seems a bit noisy to me, but I did find a pattern there from about 50 years.

John, Arno would have to explain his erroneous description and assumptions.
In reality: the trade winds and sea surface temperatures are closely coupled, and it’s a positive feedback loop, known as Bjerknes feedback. Something has to disrupt the positive feedback of the “normal” state in order for there to be an El Niño. Contrary to what Arno wrote, it’s a relaxation of the trade winds in the western tropical Pacific that initiates the El Niño. When the trade winds relax, gravity causes the warm water that was piled up in the west to slosh east. The mechanics of this have been known for decades. The trade winds relax due to weather-related phenomena called Westerly Wind Bursts, and there are a number of causes of those.

Can’t really blame NCDC for using 1895; that’s when the Weather Bureau set up its telegraph observation network, so it’s the start of regular records for most of America. It’s not a deliberate fudging of timeline. But starting at 1895 skips half of the curve, so most records are heading mainly upward since then.
————————————————–
The weather bureau records go back to 1735 and Harvard started a weather observatory in Boston in 1743. The weather bureau even has Arctic records starting in 1881, the first international polar year, when the Greely expedition sailed right up the then ice-free Nares strait and established a weather observatory at the northern end of Ellesmere Island.
http://www.archives.gov/research/guide-fed-records/groups/027.html
The NCDC US temperature records use to start in 1867, then 1880 and now 1895. In 1860, there were 500 individual stations already operating. 1895 is just a convienently low starting point. 1881 average temperatures got to +0.4C and the NCDC could not have that for example. 1878 got to +0.65C.
So, here is the US temperature record back to 1743 (courtesy of Berkeley Earth and the NCDC – note that Berkeley has a 28% higher trend than the NCDC in the overlap period which appears to be the case with all of Berkeley Earth’s data – it has a higher trend than other available records which has not been explained so far – I believe their record splitting algorithm favours splitting break-points that go up over break-points that go down – who knows how that has affected the 1743 temperature record).

Westerly Wind Bursts: ENSO’s Tail Rather than the Dog?
“Westerly wind bursts (WWBs) in the equatorial Pacific occur during the development of most El Niño events and are believed to be a major factor in ENSO’s dynamics. Because of their short time scale, WWBs are normally considered part of a stochastic forcing of ENSO, completely external to the interannual ENSO variability. Recent observational studies, however, suggest that the occurrence and characteristics of WWBs may depend to some extent on the state of ENSO components, implying that WWBs, which force ENSO, are modulated by ENSO itself.”

Bob, I have a question regarding SSTs.
Your graphs (thanx for using actual Temps) suggest near US ocean waters are around 295K, and I guess that globally we can be fairly sure they are greater than 273K.
So some 70% or so, of the earth surface (sans Arctic Ocean) is a pretty good mimic of a black body radiator (well gray anyway) with an emissivity (where it matters) of around 0.97-0.98
So MY BB radiation calculator, says that the largest near BB radiator on the planet, is emitting a roughly black body spectrum with a peak spectral emittance at something between 9.86, and 10.65 microns, with a mean of 10.1 microns at 288K. Some of the hottest desert surfaces must be peaking as low as 8.75 microns, and at nearly double the emittance of the 288K mean earth.
So how in the hell can earth’s external emission spectrum correspond to an equivalent Temperature as low as 255 K , when there doesn’t seem to be ANY global BB like emitter that is at that Temperature ?
We are told that the atmospheric gases do not emit a BB spectrum, since the normal atmospheric gases N2 and O2 don’t radiate, and atmospheric emission can only consist of greenhouse gas molecular line spectra (in bands) which don’t shift fequency with Temperature like BB thermal emission does.
So what gives. Why does earth IR emission not look like a 273-295 K Thermal spectrum, with holes for the main GHG absorption bands. I expect to see holes, since the bands absorbed by GHG such as CO2, O3, and H2O, must get reradiated isotropically, so only about half can directly escape.
So I’m puzzled; earth should not be emitting much in the way of a 255 K spectrum.

tallbloke says: “Westerly Wind Bursts is a phenomenological descriptor which tells us nothing. Please tell us more about the causes you allude to.”
From chapter 4.15 of my soon-to-be-competed (yipeee!) book “Who Turned on the Heat?”
A phenomenon known as a Westerly Wind Burst (WWB), also known as a Westerly Wind Event (WWE), accompanies the relaxed trade winds. So if you wanted to investigate this further, those would be the phrases to use in your searches. There are multiple causes of Westerly Wind Bursts, including:
1. Cross-equatorial tropical cyclones in the western tropical Pacific. This refers to a time when one tropical cyclone exists north of the equator in the western tropical Pacific, while at the same time, another tropical cyclone exists there but south of the equator. These are discussed in Keen (1982) The Role of Cross-Equatorial Tropical Cyclone Pairs in the Southern Oscillation.
2. A single cyclone and series of cyclones in the western tropical Pacific. These are discussed in Hartten (1996) Synoptic settings of westerly wind bursts.
3. Cold surges from mid-latitudes, discussed in Harrison (1984) The appearance of sustained equatorial surface westerlies during the 1982 pacific warm event
4. Convective cloud clusters associated with the Madden–Julian oscillation (MJO). Refer to Zhang (1995) Atmospheric Intraseasonal Variability at the Surface in the Tropical Western Pacific Ocean.
As noted earlier, there are a plethora of other papers that discuss these factors. There is a good overall discussion in Vecchi and Harrison (2000) Tropical Pacific Sea Surface Temperature Anomalies, El Niño, and Equatorial Westerly Wind Events.
tallbloke: And based on your follow-up comment, there’s no need for me to link that paper as well. But the statement you quoted (“…the occurrence and characteristics of WWBs may depend to some extent on the state of ENSO components, implying that WWBs, which force ENSO, are modulated by ENSO itself.”) is not unrealistic. ENSO simply provides feedback to itself.
