NOAA has declared that a La Niña is underway. This cool weather event is likely to be shorter and weaker than usual, but will still affect global weather and climate.
A long-awaited La Nina has finally appeared, but the periodic cooling of Pacific Ocean waters is weak and unlikely to cause as many weather problems as usual, meteorologists said Thursday. La Nina, the flip side of the better-known El Nino,
La Niña is finally here. The National Oceanic and Atmospheric Administration announced that conditions have officially formed to declare the weather event. The post NOAA: La Niña Conditions Have Officially Emerged first appeared on The Inertia.
Weather patterns across the U.S. and the world from October through December resembled patterns from previous La Niña events. 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,
The Pacific Northwest, Midwest and Northeast are expected to face above-average precipitation, according to NOAA. States with a higher chance of increased precipitation between November and January include Washington, Oregon, Idaho, Montana, Wisconsin, Michigan, Illinois, Indiana, Ohio, Pennsylvania and New York.
It's not great news for the Gulf Coast and other storm-prone regions: La Niña is associated with more tropical activity in the Atlantic Ocean. But this event might not make it to hurricane season.
NOAA: La Niña has officially arrived, though late, and is expected to remain weak, with a 59% chance of persisting through February-April
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.
The latest El Nino-Southern Oscillation (ENSO) update by the National Oceanic and Atmospheric Administration on Jan. 9 announced La Nina's arrival.
La Niña Definition La Niña is one half of the El Niño–Southern Oscillation (ENSO) cycle—when the east-central tropical Pacific turns cooler than average and the Walker circulation (the prevailing atmospheric pattern over the Pacific) strengthens.
A long-awaited La Niña has finally appeared, but meteorologists say the periodic cooling of Pacific Ocean waters is weak and unlikely to cause as many weather problems as usual.
