Detailed explanation-1: -El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North.
Detailed explanation-2: -Elsewhere over the United States, El Niño impacts are associated with drier conditions in the Ohio Valley, and there is a less-reliable dry signal in the Pacific Northwest and the northern Rockies. Hawaii also often experiences lower-than-average rainfall totals from the late fall through early spring period.
Detailed explanation-3: -El Niño is a warm climate condition that occurs when there is an increase in the amount of water in the equatorial Pacific Ocean. 2. This warm water moves toward the coast of South America, causing dry heat throughout North America and warm water moving toward the coast of South America.
Detailed explanation-4: -An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
