El Niño and La Niña affect the global climate and disrupt normal weather patterns, which as a result can lead to intense storms in some places and droughts in others. [6] [7] El Niño events cause short-term (approximately 1 year in length) spikes in global average surface temperature while La Niña events cause short term surface cooling. [8]
The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
The weather impacts of La Niña in the U.S. are often most apparent during the winter, although the climate pattern typically lasts nine months to a year and can occasionally last for years ...
NOAA's Climate Prediction Center (CPC) announced Thursday that water temperatures in critical parts of the Pacific Ocean had finally reached the threshold required for La Niña to emerge in December.
El Niño finally lost its grip on global weather in June, but La Niña’s arrival was delayed repeatedly, leaving an extended period of neutral conditions in place through the summer and fall.
The National Oceanic and Atmospheric Administration’s Climate Prediction Center says there is a 60% chance that a weak La Nina event will develop this autumn and could last until March. La Nina is part of a natural climate cycle that can cause extreme weather across the planet — and its effects vary from place to place.
Meteorologists from the National Weather Service Climate Prediction Center said there's a 60% chance La Nina will emerge between September and November, and persist through January-March 2025.
La Nina, a climate phenomenon marked by cooler-than-usual ocean temperatures in the central and eastern equatorial Pacific, is linked to a mix of extreme weather events, from devastating floods ...
