How are La Niña, El Niño seen in Pacific Ocean Sea Surface Temperature
deviations from normal average values?

Sea surface temperature anomalies  during La Nina, normal and El Nino conditions in the Pacific Ocean

 

 

Sea Surface Temperature Anomaly is the deviation of observed Sea Surface Temperature from the average value usually seen for the month. These are graphics of temperature deviations for major El Niño / La Niña events in the mid-1990's, shown for the entire Pacific Ocean (70N to 70S).

  • La Niña is a a colder-than-normal event, and is indicated by blue colors in the plot.

  • Normal conditions are indicated by green color in the plots.

  • El Niño is a warmer-than-normal event, and is indicated by red colors in the plot.

The data are from the Reynolds Sea Surface Temperature (SST) analysis obtained from the National Center for Environmental Prediction (NCEP).

Graphics are provided by the TAO project and created by Dai McClurg.
