Sea-Surface Temperature Anomalies: El Niño
OceansPhysical EnvironmentA composite of sea-surface temperature anomalies during El Niño from November to March during the following years: 1958, 1966, 1973, 1983, 1987, 1992, 1996, and 1998. When sea-surface temperatures in the tropical eastern Pacific rise well above normal, it is known as an El Niño event.
