Sea Surface Height Anomalies during El Nino/La Nina Event of 1997-1998 (WMS)
The El Nino/La Nina 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 computed from TOPEX/Poseidon altimeter data.
This animation shows El Nino and La Nina 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 -21 to +21 latitude and +120 to +290 East longitude.
