Explain the science behind how El Niño and La Niña are able to influence weather patterns worldwide?. Geography

Natural climate cycles; During an El Niño a giant pool of warm water that normally sits in the central Pacific

surges east all the way to South America; during a La Niña it shrinks and retreats into the western Pacific. Heat

and water vapor coming off the warm pool generate powerful thunderstorms. El Niño tends to push drenching

storms over the southern U.S. and Peru while visiting drought and fire on Australia
