I’ve moved to WordPress. This post can now be found at Mid-August 2010 SST Anomaly Update
#########################NOTE: The weekly OI.v2 SST data is available in two periods through the NOAA NOMADS website, from November 1981 to 1989, and from 1990 to present. The mid-month posts now include the full term of the NINO3.4 and Global SST anomalies from 1990 to present and a shorter-term view from 2004 to present to make the recent wiggles easier to see.

NINO3.4
NINO3.4 SST anomalies for the week centered on August 18, 2010 show that central equatorial Pacific SST anomalies have reached an initial plateau. Presently they’re at -1.1 deg C, which is 0.21 deg C higher than the lowest value that occurred three weeks ago.

GLOBAL
Weekly Global SST anomalies are still elevated and are firmly planted in a mid-year stall. They don’t appear to want to rise or fall. Will they make a sizable drop as they had during 2007?

COMPARISON TO PAST LA NIÑA EVENTS
And for those wondering where the present NINO3.4 SST anomalies stack up against prior La Niña events, I’ve provided the following comparison.
