Wind 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. Deviations from normal winds speeds and directions of the were computed using data from the Special Sensor Microwave/Imager (SSMI) on the Tropical Rainfall Measuring Mission (TRMM) satellite.

This animation shows El Nino and La Nina from 1997 through 1998. Each frame is a ten-day average of wind anomalies--that is, of differences from normal wind velocities. The area shown in the animation is the Pacific ocean from -21 to +21 latitude and +120 to +290 East longitude.    This animation shows El Nino and La Nina from 1997 through 1998.
