Briefly summarize the El Niño Southern Oscillation.
What will be an ideal response?
In anEl Niño Southern Oscillation, winds that usually blow more-or-less constantly from east to west weaken or reverse direction. This allows the warmer waters of the western Pacific to move toward the coast of South America. A horizontal zone of gradual temperature change called a thermocline, separating warm and cold waters, sinks in the eastern Pacific. These changes result in drier weather in some areas and wetter weather in other areas.
