El Niño, a periodic warming of the Eastern Pacific Ocean, is among Earth's most powerful phenomena. Satellite, ship, and buoy observations show the 1997-98 event as the strongest on record. Visualizing how sea-surface height, sea-surface temperature, and sea-surface winds differ from normal conditions reveals the event's magnitude.

Four animations of data sets in the Pacific from January 1997 through July 1998, showing the difference of El Niño conditions from normal. The data sets are sea surface height anomaly, sea surface temperature anomaly, and sea surface wind anomaly.
