That’s because these events will become less connected with what happens halfway around the world in the Atlantic, researchers report online August 21 in Science Advances.
In today’s climate, cooling in the waters of the equatorial Atlantic, called an Atlantic Niña, can lead to especially warm water in the equatorial Pacific, or El Niño (SN: 5/28/16, p. 13). Meanwhile, warmer Atlantic Niño waters tend to give rise to the cooler waters of La Niña in the Pacific. That call-and-response relationship, which involves air being swept into the atmosphere from over the Atlantic and settling down over the Pacific, can give forecasters an edge in anticipating destructive El Niño and La Niña events.
