La Niña

La Niña is a climate pattern that occurs when ocean temperatures in the central and eastern Pacific Ocean become cooler than usual. This phenomenon affects global weather, typically leading to wetter conditions in some regions, like the western Pacific, and drier conditions in others, such as the southern United States. It is part of a larger cycle known as the El Niño-Southern Oscillation (ENSO) and usually lasts several months to a couple of years. La Niña can influence hurricane activity, agriculture, and water supply in various parts of the world.
