Southern Oscillation

The Southern Oscillation is a climate pattern that involves fluctuations in air pressure between the western and eastern parts of the tropical Pacific Ocean. It is closely linked to El Niño and La Niña events, which affect global weather. During El Niño, warm water and low pressure build up in the eastern Pacific, leading to wetter conditions there and drier weather in the west. In contrast, La Niña features stronger trade winds and cooler waters in the eastern Pacific, often causing opposite weather effects. This oscillation plays a crucial role in influencing climates around the world.
