Both of these cycles have longstanding climate patterns. Scientists stunned after satellite data unveils new information ...

Early signs of a possible La Niña fall and winter are emerging in some climate models, federal forecasters announced Thursday ...

El Niño occurs more often than La Niña. El Niño takes place when trade winds weaken and unusually warm sea surface water is pushed east, forcing the Pacific jet stream further south than usual.

The current El Niño is now one of the strongest on record, new data shows, catapulting it into rare “super El Niño” territory, but forecasters believe that La Niña is likely to develop in ...

El Niño and La Niña sometimes don’t follow the expected patterns. And strength matters: A strong El Niño, for instance (as measured by how high sea-surface temperatures are above normal) ...

After three consecutive years of an unusually stubborn pattern, La Niña has officially ended and El Niño is on the way, the National Oceanic and Atmospheric Administration said Thursday.

“The old La Niña playbook and the old El Niño playbook don’t seem to be as reliable as they used to be,” said Jan Null, an adjunct professor of meteorology at San Jose State University.

La Niña can often last for longer than El Niño. During La Niña, there was increased drought in the southern U.S. along with heavy rains and flooding in Canada and the Pacific Northwest.

El Niño helped drive global average temperatures to new records over the last year. Forecasters say it's waning, but that 2024 may still be one for the record books.

Rippey says just like the impacts of El Niño are still being felt four months after its peak, the claws of La Niña may not come until fall. “Even if we make that transition into La Niña by ...

La Niña essentially gets its name from being the opposite of El Niño. It has also been called “El Viejo, anti-El Niño, or simply a ‘cold event,'” NOAA says.
