>The January 2010 SST data through the NOAA NOMADS website won’t be official until January 8th, according to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questions webpage. But NOMADS as usual has produced preliminary values. The following graphs include the preliminary Global and NINO3.4 SST anomalies for January 2010. I’ve also included the official weekly data through January 27, 2010.
Monthly NINO3.4 SST anomalies appear to have peaked in December. SST anomalies have dropped 0.23 deg C over the past month.
Monthly NINO3.4 SST Anomalies
The downturn is confirmed by the weekly NINO3.4 SST anomaly data, with the most recent value centered on January 27, 2010. It has dropped 0.71 in five weeks.
Weekly NINO3.4 SST Anomalies
Monthly Global SST anomalies have dropped 0.032 deg C since December 2009, but that does not mean they won’t take another swing upwards or remain at the elevated levels for a month or two.
Monthly Global SST Anomalies
Weekly Global SST Anomalies are still elevated and have not yet shown a sign of taking the normal downturn in response to the drop in NINO3.4 SST anomalies.
