Sea Surface Height Anomalies during El Niño/La Niña Event of 1997-1998 (WMS)

Visualizations by Jeff de La Beaujardiere Released on April 1, 2005
The El Niño/La Niña event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. Changes in the normal height of the ocean's surface were observed by the TOPEX/Poseidon altimeter.

This animation shows El Niño and La Niña from 1997 through 1998. Each frame is a ten-day average of sea surface height (SSH) anomalies—that is, of differences from normal SSH values. The area shown in the animation is the Pacific ocean from -20.5 to +20.5 latitude and +120.5 to +289.5 East longitude.
