Hot Air over Hot Water
El Niņo happens when
weakening trade winds (which
sometimes even reverse
direction) allow the warmer
water from the western Pacific to
flow toward the east. This
flattens out the sea level, builds
up warm surface water off the
coast of South America, and
increases the temperature of the
water in the eastern Pacific.
An El Niņo condition results from weakened trade winds in the western Pacific
Ocean near Indonesia, allowing piled-up warm water to flow toward South
America.
