VERY, VERY Preliminary July 2009 SST Anomalies

I’ve moved to WordPress.  This post can now be found at VERY, VERY Preliminary July 2009 SST Anomalies
####################
A quick check of the NOAA NOMADS system for the OI.v2 SST data revealed that the preliminary July 2009 data had been posted yesterday. Based on the schedule listed in the following FAQ page, the data will not be finalized until July 10.

So here’s a brief early look at the direction the global and NINO3.4 SST anomaly data are headed. Preliminary July 2009 Global SST anomaly data is showing a very slight drop, -0.02 deg C, since June 2009, while NINO3.4 SST anomalies are continuing their rise. Preliminary July 2009 NINO3.4 SST anomalies are 0.93 deg C, up 0.32 deg C since June. The graphs follow.

But first, here’s the preliminary map. It’s still showing the unusual pattern in the North Pacific, though it’s becoming less defined. Refer to my post “The Unusual SST Anomaly Pattern in the Pacific.”

And comparing the July and June maps in an animated gif, the unusual warm area in the Northeastern tropical Pacific appears to be ebbing as the waters along the equator are warming. Is this a result of the increased convection over the equator as SST there rises? This would cause an inflow of winds and, in turn, probably lower the SST in the adjacent tropics as the surface waters are drawn toward the equator.

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.
