Question

Quizplus · Accepted Answer

El Niño is characterized by a weakening or reversal of the trade winds, which causes warm water to migrate eastward across the equatorial Pacific Ocean. This warm water accumulates along the coasts of South and Central America, which leads to atmospheric changes that result in the reversed Walker circulation. However, deepening of the thermocline near Indonesia and Australia is associated with La Niña, the opposite of El Niño.
