El Niño forms when warm water accumulates in the central and eastern Pacific Ocean due to weakened trade winds. This change disrupts normal oceanic and atmospheric patterns, leading to a rise in sea surface temperatures. Specifically, conditions conducive to El Niño include a significant decrease in the strength of the trade winds and a shift in ocean currents, allowing for the displacement of warm water eastward. Additionally, the phenomenon often coincides with changes in atmospheric pressure, known as the Southern Oscillation.
