Animation Of Weekly Global SST Anomaly Maps – November 1, 1981 To January 6, 2010

I’ve moved to WordPress.  This post can now be found at Animation Of Weekly Global SST Anomaly Maps – November 1, 1981 To January 6, 2010
#################
The following is the animation of weekly global SST anomaly maps (OI.v2 SST data) from November 1, 1981 To January 6, 2010. The contour intervals were set at 0.2 deg C to bring out the smaller changes in SST anomalies that are caused by the ENSO-induced changes in atmospheric circulation, the teleconnections.

I had prepared the majority of the maps used in the animation back in July, and began work on a video detailing the rise in global Sea Surface Temperature (SST) anomalies since November 1981. The video got put aside. At nearly 30 minutes combined, the 3-part video was too long, and I still had more to say. Many of the graphics have appeared in subsequent posts, so that work wasn’t a waste.

Recently, two visitors have asked me about SST anomaly patterns in specific basins. This video would have been helpful to them and others looking for a means to easily display those patterns. Simply let the video play through to the desired months. Or watch for the pattern and see if an El Nino or La Nina event is taking place.

To explain the added warming in the North Atlantic, I refer to the Atlantic Multidecadal Oscillation, but I use the paleoclimatological reconstruction as a graphic instead of the normal detrended North Atlantic SST anomalies since the 1800s. More on this in a subsequent post.

Dear Mr. Tisdale,

From your latest video, running up until january 2010 I think we can acspect a quiet strong/heavy el nino effect this year.

Elswher on the internet the question has been put up whether the 2009/2010 el nino effect is extremely strong.

What is your opinion?

With kind regards,

Marius: The SST anomalies of the 2009/10 El Nino are presently in strong El Nino range...

...but it is far short of a Super El Nino, like the ones in 1982/83 and 1997/98.

The 2009/10 is large enough to have a multiyear aftereffect. This is why I've added the East Indian and West Pacific dataset...

The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.

Please use the search feature in the upper left-hand corner of the page for posts on specific subjects.

NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me. Thanks.
