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

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 ...

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.

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.

The last three transition years where we went from an El Niño Winter to a La Niña Summer were 2007, 2010, and 2016. Rain amounts during those years were either near normal, or well above normal ...

El Niño and La Niña significantly impact Earth's weather patterns. We explore the events in more detail here and take a look at how they impact Earth's weather.

“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 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.

A strong El Niño pattern has been in place over the Pacific Ocean during the 2023-2024 winter season. This year's winter impacts of warmer weather may vary wildly as the Pacific Northwest ...
