Answer:
El Niño is a meteorological phenomenon that occurs between three and seven years in the intertropical zone in the Pacific Ocean, near the coasts of South America. It is produced by the warming of the Pacific Ocean.
Explanation:
The name of El Niño is due to fishermen in Peru. They observed that the cold waters of the Humboldt stream warmed on Christmas dates, causing the fish to disappear. He was called that because they related him to Christmas. When this phenomenon occurs, storms are much stronger and more frequent. More intense rains occur on the west coast of South America.
During an El Niño, the trade winds weaken in the central and western Pacific. Surface water temperatures off South America warm up, because there is less upwelling of the cold water from below to cool the surface. The clouds and rainstorms associated with warm ocean waters also shift toward the east.
