The 1997-98 El Niño

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.
