A detailed analysis found La Niña began in December 2024 with a weak La Niña favored during the rest of this winter. La Niña is the cool phase of ENSO (El Niño-Southern Oscillation) that is ...
The weak La Niña is forecast to stick around through April before yielding once again to so-called neutral — not La Niña or El Niño — conditions, according to the Climate Prediction Center.
La Niña is considered to be the cool phase of the El Niño-Southern Oscillation (ENSO) and is characterized by lower-than-average sea-surface temperatures, with anomalies of at least -0.5 degrees ...
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 ...
But during La Nina, the trade winds intensify and cold water from the depths of the sea rises up, resulting in cooler than average ocean temperatures in the eastern Pacific. These cold ocean temperatures and changes in the atmosphere affect the position of the jet stream — a narrow band of fast moving air flowing from west to east around the ...
On Thursday, NOAA issued a La Niña watch, explaining that it could replace El Niño before the end of summer. This could have implications for the impending Atlantic hurricane season and beyond.
During La Niña, increased precipitation is diverted into the Pacific Northwest due to a more northerly storm track. [209] During La Niña events, the storm track shifts far enough northward to bring wetter than normal winter conditions (in the form of increased snowfall) to the Midwestern states, as well as hot and dry summers. [210]
The long-promised La Niña climate pattern hasn't yet formed but is still expected to within the next month or so, federal scientists say.. Specifically, the Climate Prediction Center said ...
