The La Niņa is the climatic antithesis of El Niņo. Whereas El Niņo created equatorial Pacific warming due to weak surface winds, La Niņa arises from very strong easterly winds that promote the upwelling of deep, cold waters to the surface of the ocean. These colder than average waters are visible in the animation as blue and purple colors. Like El Niņo, the La Niņa also alters global precipitations, ocean and atmospheric circulation. These climatic changes differ depending on the region examined.
