"El Niño is the warm phase of ENSO, a recurring climate pattern in the tropical Pacific that can redirect the jet stream and reshape winter across North America."
"Forecasters need both the ocean signal and the atmospheric response, looking for sustained warming in the Niña-3.4 region of the equatorial Pacific, generally on the order of 0.5°C or more."
"In a neutral setup, easterly trade winds blow along the equator, pushing warm surface water westward toward Indonesia, leaving the eastern Pacific relatively cooler."
"The Southern Oscillation is a basin-scale seesaw in surface pressure between the western and central-eastern tropical Pacific, tracking the strength of the trade winds."
El Niño represents the warm phase of the El Niño-Southern Oscillation, influencing winter weather patterns across North America. It occurs every two to seven years, typically lasting 9 to 12 months. Forecasters monitor ocean temperatures in the Niña-3.4 region and corresponding atmospheric changes. In neutral years, trade winds push warm water west, creating cooler conditions in the eastern Pacific. This setup affects tropical thunderstorms and the distribution of heat, with the Southern Oscillation reflecting changes in surface pressure and trade wind strength.
