>Mid-March 2010 SST Anomaly Update

>NINO3.4 and Global SST anomalies are still stalled at the levels they’ve been at for the last six weeks.

NINO3.4 SST anomalies for the week centered on March 17, 2010 show that central equatorial Pacific SST anomalies have remained relatively level for the past month and a half. Presently they’re at 1.19 deg C.

The delay in the decline is likely the response to another Kelvin wave. Refer to the .gif animation of the subsurface temperature anomalies for the equatorial Pacific.

Weekly Global SST anomalies are still elevated, but they are lower than the peak for this El Nino. Like the NINO3.4 SST anomalies, the Global SST anomalies appear content to cycle where they are now. There’s still no indication that there will be a lagged rise.

OI.v2 SST anomaly data is available through the NOAA NOMADS system:
