El Niño, which occurs when Pacific trade winds die out and ocean temperatures become unusually warm, is the warm phase of an oscillation called the El Niño/Southern Oscillation (ENSO).
Named by fisherman off the coast of South America, El Niño, or “the little one” in Spanish, originates in the tropical Pacific ocean-atmosphere system, and affects weather pattern variability all over the world, according to the National Oceanic and Atmospheric Administration (NOAA).
