| The images and animations shown here are visualizations of the El Niño phenomenon that occurred in 1982 and 1997, two of the strongest El Niño events on record. | ||||

Temperature anomalies represent the departure from normal sea surface temperatures. Red shows regions where the water is warmer than normal and blue shows regions where the water is cooler. El Niño shows up as the large red area off the West coast of South America. |

1982-84 1995-97 These images were created using raytracing to compute shadows and reflections and produce an artistic view of El Niño events.
|
These images show a comparison between two large El Niño events. The first begins in Oct '81 and the second in Oct '96. As the El Niño event in the second animation begins to fade, a La Niña event begins to emerge in the early part of '98.

Also included here is a VRML
representation of a subset of the imagery that provides interactive
navigation through a VRML world. |
