During normal atmospheric conditions in the Pacific Ocean

• Strong winds blow water towards the coast of South America

• Strong winds blow water away from South America

• Cold, nutrient poor water moves towards the surface

• there is a low level of productivity along the coast of South America.

During an El Nino event,

• Upwelling along the South American Coast stops

• Upwelling along the South American Coast is amplified

• prevailing trade winds increase, pushing warm water west towards Australia.

• Productivity increases along South American Coastline.
