The Hadley circulation is a key atmospheric circulation pattern in the tropics. It helps even out the temperature between the equator and the poles by moving energy and momentum toward higher latitudes. However, recent studies indicate that the Hadley circulation cells have expanded toward the poles in the 21st century, increasing by several degrees each year. This expansion can have a substantial impact on the global weather and climate, resulting in adverse events like heat waves, droughts, and tropical cyclones
