The Walker circulation is a major atmospheric phenomenon that encompasses the tropical Pacific Ocean, describing a large-scale pattern of wind and air movement. This circulation system involves the convergence of moist air at the surface and its subsequent ascent over the central Pacific. The pattern’s strength and movement are strongly influenced by temperature gradients and ocean conditions, creating a feedback loop with regional weather. Variations in the intensity and location of this circulation are crucial drivers of global climate variability, influencing the occurrence and severity of major climate phenomena, including drought and excessive rainfall, across the tropical latitudes.
