Final answer:
El Niño is a climate cycle that affects weather patterns globally. Under normal conditions, winds push warm surface water from South America to Indonesia, causing colder water to rise. During El Niño, weakened winds cause warm water to accumulate near South America, leading to increased rainfall.
Step-by-step explanation:
El Niño is a climate cycle that occurs in the Pacific Ocean and affects weather patterns globally. Under normal conditions, powerful winds blow warm surface water towards Indonesia, causing colder water to rise to the surface near South America. However, during El Niño conditions, the winds weaken or even blow in the opposite direction, causing warm water to accumulate along the coast of South America. This leads to the formation of clouds and increased rainfall in certain regions.
