For Those Watching the Sea Surface Temperature Anomalies of the Equatorial Pacific and the Decay of the El Niño

Watts Up With That?

Guest Post by Bob Tisdale

Many readers are keeping an eye on the sea surface temperature anomalies of the eastern equatorial Pacific. The latest sea surface temperature anomaly map from the CMC Environment Canada (Figure 1) shows cooler than normal sea surface temperature anomalies along the equatorial Pacific east of about 125W, indicating the tropical Pacific is heading toward La Niña conditions. (Note the odd base years for anomalies used by CMC Environment Canada, 1995 to 2009.)

The following are updates of the two sets of graphs of NINO region sea surface temperature anomalies that have been part of the 2014/15 El Niño series and the 2015/16 El Niño series.
