Introduction to Oceanography
Strong trrade winds-
El Niño—large pool of warm surface water in western Pacific
La Niña—so much upwelling of cold water in eastern Pacific that it spreads to west, cooling sea surface temperatures
El Niño and La Niña and the Asian monsoons. When surface temperatures in the eastern equatorial Pacific are warmer than usual (an El Niño event), heavy rains hit East Africa and droughts beset India, Indonesia, and Australia. When ocean conditions flip-flop (a La Niña), so do rainfall patterns across Asia. From http://www.whoi.edu/oceanus/v2/article/images.do?id=53506
