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 ...

The surprising January heat record coincides with a new study by a climate science heavyweight, former top NASA scientist ...

The last El Niño, the periodic warming of Pacific Ocean waters, finished in June 2024. NOAA forecasters have been expecting La Niña for months. The previous La Niña concluded in 2023 after an ...

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

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.

Forecasters closely monitor La Niña and its counterpart El Niño because they influence global weather in a way that’s largely consistent and predictable well in advance – especially when the ...

However, it is expected to be weaker and shorter than usual. La Niña is the cold phase of a natural climate pattern called the El Niño Southern Oscillation (ENSO) cycle, which is a pattern of ...

During El Nino, warmer Pacific water helps form thunderstorms ... The conditions are opposite during La Nina, when cooler Pacific temperatures result in downdrafts there, and reduced wind shear ...

But forecasters with the National Oceanic and Atmospheric Administration expect this La Niña event to be a weak one, and its chances of lasting through the next hurricane season are low.

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 ...

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.
