Definition

The Pacific Warm Pool (PWP) is defined as the area in the Western Tropical Pacific enclosed by the 28.5 deg C isotherm.

This body of water, which spans the western waters of the equatorial Pacific to the eastern Indian Ocean, holds the warmest seawaters in the world. Scientists found that, over a period of roughly two decades, the warm pool’s average annual temperatures and dimensions increase and then decrease like a slowly pulsating beacon.

Discussion

Because these waters are hot enough to drive heat and moisture high into the atmosphere, the warm pool has a large effect on the climate of surrounding lands. In fact, the slow fluctuations of size and intensity of the warm pool may be linked with the intensity of El Niño.
