Understanding the Enigma of El Niño El Niño is a fascinating climate phenomenon that impacts weather and ecosystems worldwide ...

La Niña is usually associated with drier conditions across the southern part of the U.S. and wetter conditions to the north.

Meteorologists say a weak La Nina weather event has arrived but will bring fewer storms than usual. Here's how the Pacific El Nino and La Nina weather phases can influence extreme weather globally.

By Shanna Hanbury It’s official: a weak La Niña came into fruition in late December and is expected, with significant ...

La Niña, the cold side of the El Niño Southern Oscillation (ENSO), typically results in colder conditions across the U.S. Northern Plains and Canadian Prairies, while it remains warm across the ...

Three recent studies reveal how the interplay between El Niño and long-term global warming drove the record-breaking global ...

After much of the world experienced the hottest year on record in 2024, the U.S. has seen a lot of cold and snow for January. This warmth was partly fueled by a strong El Nino that peaked last year ...

An El Niño weather pattern—La Niña’s counterpart—brought the warmest winter on record last year. La Niña conditions emerged in December and will likely persist through April, though the ...

The La Nina and El Nino patterns are dictated by our ENSO regions in the equatorial Pacific. There are four individual regions that meteorologists and oceanographers monitor annually to determine ...

La Niña is the cool phase of ENSO (El Niño-Southern Oscillation) that is marked by sea-surface water temperatures 0.5ºC below the climatological average in a key area of the eastern Pacific.

Here's what you need to know. La Niña is the opposite phase of the El Niño-Southern Oscillation (ENSO) cycle and often brings distinct weather patterns. During a La Niña event, cooler waters in ...

NOAA says La Nina ocean cooling has finally arrived, but it’s weak and may cause fewer problems Last winter (2023-2024) was an El Niño winter marked by cooler and wetter weather for the ...
