AI Summary

NASA scientists are monitoring an El Niño event unfolding this fall that they describe as rarer than a solar eclipse and more powerful than any single storm system. The climate pattern, which appears roughly every two to seven years, is characterized by warmer‑than‑normal water temperatures in parts of the equatorial Pacific. As it develops, the event is flipping trade winds, redistributing ocean heat, scrambling regional rain patterns and raising sea‑surface height across portions of the Pacific.
