El Niño and La Niña are the opposite phases of ENSO, which is short for El Niño-Southern Oscillation. Operating in the tropical Pacific Ocean, ENSO is Earth's singlest most influential natural climate pattern. El Niño and La Niña alternately warm and cool large areas of the tropical Pacific - the world's largest ocean - which significantly influences where and how much it rains there. The primary location of moist, rising air is centered over the central or eastern Pacific during El Niño and over Indonesia and the western Pacific during La Niña. Like a boulder in a stream, this relocation disrupts the atmospheric circulation patterns that connect the tropics with the middle latitudes, which in turn modifies the mid-latitude jet streams. By modifying the jet streams, ENSO can affect temperature and precipitation across the United States and other parts of the world.
