>The April 2010 SST data through the NOAA NOMADS website won’t be official until Monday April 10th. Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questions webpage. However, the following are the preliminary Global and NINO3.4 SST anomalies for April 2010 presented by the NOMADS website today, Monday, April 26, 2010. I’ve also included the weekly data through April 21, 2010, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the wiggles are visible.
Based on the preliminary data, monthly NINO3.4 SST anomalies are continuing to drop, and the drop accelerated after the slowdown last month. They’ve dropped ~0.41 deg C over the past month.
Monthly NINO3.4 SST Anomalies
Monthly Global SST anomalies, according to the preliminary data, increased 0.034 deg C since March.
Monthly Global SST Anomalies
The weekly NINO3.4 SST anomaly data, with the most recent value centered on April 21, 2010, shows a continued decline.
Weekly NINO3.4 SST Anomalies
Weekly Global SST Anomalies are still elevated and have not yet begun their lagged drop in response to the decline in NINO3.4 SST anomalies.
Weekly Global SST Anomalies
