The El Niño/La Niña event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. Deviations from normal winds speeds and directions were computed using data from the Special Sensor Microwave/Imager (SSMI) on the Tropical Rainfall Measuring Mission (TRMM) satellite.

This animation shows El Niño and La Niña 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.

Color scale for wind speed anomalies. The values range from 0 to 1.5 meters per second. The direction of the wind anomaly in each cell is shown by an arrow.
