Differences and Characteristics

El nino

El Nino begins when an unusual pattern of winds forms over the western Pacific. El Niño causes the surface of the ocean in the eastern Pacific to be unusually warm.

La nina

When the surface waters in the Eastern Pacific are colder than normal, a climate event known as La Nina occurs. A La Nina event is the opposite of an El Nino event. Al Nina events typically bring colder than normal winters and greater precipitation to the Pacific Northwest and the North central United States.
