El Nino - What is it Anyway?

El Nino is an unusual warming of surface ocean waters in the eastern tropical Pacific. It is the pattern of reversing surface air pressure between the eastern and western tropical Pacific. When the surface pressure is high in the eastern tropical Pacific it is low in the western tropical Pacific.

The ocean warming and pressure reversals happen at the same time. The name came from South American fisherman.  El Nino is Spanish for "The Christ Child". This weather pattern comes about the time of the celebration of the birth of the Christ Child Christmas.
