I’ve moved to WordPress. This post can now be found at Mid-September 2009 SST Anomaly Update
###############A GIF animation of the OI.v2 SST anomaly maps for the Weeks Centered On August 19 and September 16, 2009 shows that the elevated SST anomalies in the mid and high latitudes of the Northern Hemisphere have reduced in magnitude. The tropical Pacific SST anomalies are still elevated, but there are no apparent indications of a strengthening El Nino. The tropical Atlantic is still not showing any areas of exceptionally warm SST anomalies.

Global SST anomalies are still elevated, but they have dropped 0.08 deg C in the last 3 weeks.

NINO3.4 SST anomalies for the week centered on September 16, 2009 are still well into El Nino territory, but they have been cycling near the same value for a few months.

And the SST anomalies in both the Southern and Northern Hemispheres are decreasing.
