Explanation:
Detailed explanation-1: -During El Niño Meanwhile, the trade winds (that typically blow along the equator from the east-to-west) weaken because they normally blow from areas of sinking motion to areas of rising motion–now those areas are reduced relative to the normal state. El Niño feedbacks between the ocean and atmosphere.
Detailed explanation-2: -El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms.
