ENSO Sea Surface Temperature Anomalies: 2009-2010

The El Niño-Southern Oscillation (ENSO) is a quasi-periodic fluctuation of ocean temperatures in the equatorial Pacific. The temperatures generally fluctuate between two states: warmer than normal central and eastern equatorial Pacific (El Niño) and cooler than normal central and eastern equatorial Pacific (La Niña).

This animation illustrates the evolution of sea surface temperature (SST) anomalies (relative to the respective normal state) in the Pacific Ocean associated with the 2009-2010 El Niño, the warm phase ENSO. SST anomalies reflect the heat content in the mixed layer (upper 50 meters). Initial warming appeared in the eastern equatorial Pacific around May 2009 and grew into a moderate El Niño event by the end of the year.
