Ever wondered why the vast expanse of the equatorial Pacific Ocean experiences a significant drop in temperature during a La Niña event? Let's uncover the fascinating atmospheric and oceanic mechanisms behind this global climate phenomenon.

Here's a breakdown of the key factors driving this cooling:
► Stronger easterly trade winds intensify, pushing warm surface water westward across the Pacific basin.
► This westward movement exposes cooler, deeper water to the surface in the eastern equatorial Pacific through a process called upwelling.
► A shallow thermocline in the eastern Pacific means less warm water is available to replace the upwelled cold water.
► Reduced cloud cover and atmospheric convection in the central and eastern Pacific allow for increased heat loss from the ocean surface.
