The_Global_Warmer Posted October 28, 2011 Share Posted October 28, 2011 That is -15 to +15 anomalies for surface air temps. To bet a better perspective of how wide they were. Almost all of Antarctica is normal of above. With a good 30 percent 5C+ above. There is those two areas with -5C or colder but that is much smaller than the warm anomalies. Africa, Australies, and South America are all below normal, combined just looking at the map around -1C maybe a bit colder. North America looks 2-4C above normal with almost no minus anomalies. When you really look at the CA as well....it adds to it. Asia is very warm as well in the 2-4C range. Europe is pretty split with warm anomalies west and north, normal in the central, and cool south. the Oceans are even for the most part but the arctic is boiling in comparison and definitely tilts air temps over the ocean to above normal. Greenland is colder and will cut into the global deficit. 2010: 2009: 1996: Huge difference. Can anyone explain to me how accurate this is.

The_Global_Warmer Posted October 28, 2011 Author Share Posted October 28, 2011 Damn I basically was showing how October 2011 is torching at the poles. And I know the total land/ocean anomaly won't be over .5 even with it looking so warm over do much of the earth. I guess the oceans make it up Link to comment Share on other sites More sharing options...

There's probably a good chance that GISS will be above .5C for the month on a 1951-1980 baseline. But the primary reason the maps usually look so warm is what you said.. that the poles where the warmth usually is are a very small % of the surface area of the earth. Smaller than you might think.

Smaller than you might think. http://www.esrl.noaa.gov/psd/data/composites/nssl/day/ 1968-1996 So probably a bit warmer than the GISS anomalies. I read on these boards that the 50s were warm. Take a look the entire NH is warm except for Greenland and a couple small areas. Antartica is also torching. Link to comment Share on other sites More sharing options...

The 1968-1996 baseline is a much warmer base than the GISS base. I just checked.. .11C difference. Link to comment Share on other sites More sharing options...

Snow_Miser Posted November 8, 2011 Share Posted November 8, 2011 October could be very very warm Looks like October came in significantly cooler on UAH than it was in September. Nearly two tenths colder. Link to comment Share on other sites More sharing options...

kylemacr Posted November 21, 2011 Share Posted November 21, 2011 That NOAA site (ESRL/PSD) uses 30 year climatology for "normals". Just take your month, say October. Add up the temps each day for each October from 1981-2010 and divide by the total number of days (930). That's all they do. In general, data from well populated places are more accurate than data from sparsely populated places (like Antarctica). That site uses NCEP reanalysis data for its fields. The data are put through a computer model and the analysis (time = 0) fields are what you see there. This means that the data are assimilated and forced to be consistent with the known equations which govern the atmosphere (better than simple statistical interpolation). Edit: oh, hey! someone showed that the base period is not actually 1981-2010, sorry! Most of the maps at ESRL/PSD are 1981-2010 though. Link to comment Share on other sites More sharing options...
skierinvermont Posted November 21, 2011 Share Posted November 21, 2011 GISS came out for the month. Slightly warmer than September at .53.. the YTD is about .51 or .52. Link to comment Share on other sites More sharing options...
kylemacr Posted November 21, 2011 Share Posted November 21, 2011 This might make things a little clearer... as someone pointed out above, the Mercator projection can enhance the poles. This is for NH only though... Link to comment Share on other sites More sharing options...

kylemacr Posted November 21, 2011 Share Posted November 21, 2011 Here's an SST (NOAA OI) map of the same period, with the same color scale... I'd say the results are comparable... Link to comment Share on other sites More sharing options...

I don't know how to run a map for the whole month, but take a look at these maps. EDIT: I guess a lot of it probably just has to do with color shading, as 0 to -1 is white on the map you posted, while all below normal is blue on my maps. Makes the below normal area look smaller.

kylemacr Posted November 21, 2011 Share Posted November 21, 2011 Ah, you must be talking about the SSTs on/near the Equator. I think it has a lot to do with color scale. I made a tropical SST map with a color scale that is similar to yours. They look much more alike now. Link to comment Share on other sites More sharing options...
