SST Anomaly Video

Back to science.
I saw this post the other day. Recently I’ve added Bob Tisdale to the blogroll basically because I got tired of having to find his blog another way. TAV does the worst job of maintaining a blogroll of any of the blogs and I need to spend more time on it b/c there are a lot of good climate science blogs not on the list. Anyway, Bob has done a very nice post containing a video of sea surface temperatures. There are some interesting features in the video, including a huge push of warm water into the Arctic during the 07 ice minimum. I’ve reposted with permission from Bob below who will stop by for those who have questions.

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.
The posts referred to in the video are:

And now the video:

It’s worth comparing to the sea ice video’s also I think.
