I’m just checking to see if I can upload a 6mb .gif animation through Windows Live Writer to WordPress. The animation is from an upcoming post about short-term and decadal variations in sea level anomalies. It appears I will be able to upload it, so I’ll leave the animation in place until I finish the post.
Animation 1
Bob, a fascinating animation showing the oceans’ heat cycling. I’ll just sit over on the sidelines (as always) awaiting the supporting article.
How much of the sea level variation is wind driven? It would be interesting to have an indication of wind strength and direction during the change of sea level that you show.
Sean: Adding wind speed and vector anomalies to the maps is beyond the mapping features of the KNMI Climate Explorer. Therefore, it is beyond my ability to prepare an animation with them. There’s a NASA Visible Earth Video that includes SSH, SST and wind components in one animation for the 1997/98 El Nino and the 1998/99 portion of the multiyear La Nina that followed:

Quite a fun movie to watch. It makes you see how important the sustained winds are to El Nino / La Nina events. It looks like the warm El Nino result in high sea levels as well as high water temps and the cool La Nina would have low water temps and low sea levels off the coast of South America. There is such a symphony of interactions between the atmosphere and the oceans. Are the slower cycles like the PDO and AMO also ocean-atmosphere coupled phenomena?
Sean: I don’t recall many papers about the AMO that go into great detail about the coupled ocean-atmosphere processes. Lorenz with his studies of the North Pacific Gyre Oscillation (the 2nd PC of detrended North Pacific SST anomalies) has been discussing the interactions between Sea Level Presuure, SST, etc., trying to close the loop.
Hi Bob,
I was just reviewing your old post
http://bobtisdale.blogspot.com/2008/12/nighttime-marine-air-temperature.html
And found it a bit frustrating that the data is only available as anomalies. Where can I find actual absolute temperature readings for night-time marine air temps?
Thanks
Tallbloke: It depends where and when you’re looking for data. For long-term global data and subsets, refer to the “MOHMAT 4.3 Tair” data at the KNMI Climate Explorer, under the heading of “Air Temperature”:
http://climexp.knmi.nl/selectfield_obs.cgi?someone@somewhere
The absolute data is the top graph after you’ve selected the coordinates. You would compare that to HADSST2 data, and of course, you have to check the maps to make sure there’s data where you’re looking since the MOHMAT4.3 and HADSST2 datasets are spatially incomplete.
If you’re looking for tropical Pacific data, there’s the “1980-now: TAO buoys” datasets under the heading of SST. There are two selections there, SST and Sea Air Temperature.
Regards
Thanks Bob.
Very nice animation . . . . if you could do the same thing with the radar information over say a 10 day (moving time frame sorta thing) . . . for both sides of the earth . . . . I would alway cite the site . . . and I bet Anthony would put a link to it . . . too!
http://www.weather.com/weather/map/USFL0231?mapdest=Radar_2100_Mile%3ASE&mapregion=us_se_4regradar_plus_usen&showanimation=yes
does some of it . . . but not enough (limited) time frame . . . and only for my (limited) area . . .
I very much enjoying reading your input in Anthony’s site . . . as well as many others . . . and am very relieved that many others with credibility have stepped up to counter the “grand delusion” that “human’s can control climate or weather” through certain actions or in-actions over any length of time . . .
I know I have asked for a tall order . . . . but, at least it is not “for the moon & the stars”!
Laurie Bowen: I wish I could do more animations. But mine are created from maps that I download (individually) from NOAA, the KNMI Climate Explorer, etc., so they take lots of time. Most of my animations have to do with ENSO events and their aftereffects. Sorry.
Ah . . . Well, no harm in askin’!
