Understanding El Niño's Impact on Global Weather

El Niño is a climate phenomenon characterized by the warming of ocean waters in the central and eastern Pacific. This warming influences atmospheric circulation patterns, leading to significant shifts in weather across the globe. During El Niño events, regions may experience above-average temperatures, altered precipitation patterns, and an increased risk of extreme weather events such as heatwaves, droughts, and heavy rainfall.
