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.

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.

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 ...

La Niña is a part of a natural climate cycle officially known as El Niño – Southern Oscillation, called ENSO by scientists. The cycle swings between warmer and cooler seawater in a region ...

La Niña, the flip side of the better-known El Niño, is an irregular rising of unusually cold water in a key part of the central equatorial Pacific that changes weather patterns worldwide.

A weak La Nina event has arrived in the Pacific, bringing colder waters and potentially cooler weather. Despite being delayed and relatively weak, La Nina may bring intense storms and rainfall ...

Last winter (2023-2024) was an El Niño winter marked by cooler and wetter weather for the southern states. The last La Nina ended in 2023 after an unusual three-year stretch. The odds favor ENSO ...

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 ...
