NOAA: Double-Dip La Niña Emerges This post was originally published on NOAA.gov A La Nina has developed and will extend through the second winter in a row according to NOAA’s Climate Prediction Center — a division of NOAA’s National Weather Service. La Nina is a natural ocean-atmospheric phenomenon marked by cooler-than-average sea surface temperatures across the central and eastern Pacific Ocean near the equator and […] Weather WeatherBrains | October 15, 2021 0 Comments
NOAA September 2021 ENSO Update: Chance of a La Niña Winter Increased to 70-80% This post first appeared on the climate.gov ENSO blog and was written by Emily Becker. It’s likely that the tropical Pacific is on the verge of getting into the La Niña groove, and forecasters estimate a 70-80% chance of La Niña this winter. NOAA’s forecast discussion says “the ocean-atmosphere system reflected ENSO-neutral [in August], but is edging toward La Niña.” […] Weather WeatherBrains | September 9, 2021 1 Comment
NOAA: Forecasters Increase Likelihood of La Niña Winter to 70% This post first appeared on the climate.gov ENSO blog and was written by Nat Johnson ENSO-neutral conditions continue in the tropics, but ENSO’s next performance may be approaching, as forecasters have increased the likelihood (~70% probability) that La Niña will reemerge by early winter. A La Niña Watch remains in effect. Related: La Niña Explained: July, the ENSO, Winter 21/22 […] Weather WeatherBrains | August 13, 2021 2 Comments
Direct Weather Shares 2021-2022 Winter Forecast Direct Weather issued their 2021-2022 winter forecast this week. Long-range forecasts like these aren’t necessarily gospel and should be taken with a grain of salt, however, teleconnection patterns can sometimes accurately indicate synoptic-scale trends. Summary: The forecast calls for above-average snowfall in the Pacific Northwest, Montana, Wyoming, and most of the East Coast this winter. The forecast calls for a drier […] Weather Clay Malott | August 5, 2021 2 Comments
NOAA: ENSO as a Climate Conductor for Global Crop Yields This is a guest post on the climate.gov ENSO blog by Weston Anderson (@HydroClim) who is an assistant research scientist with the Earth System Science Interdisciplinary Center at the University of Maryland and NASA Goddard Space Flight Center, where he works with the Famine Early Warning System team. A couple of weeks ago, NOAA issued a La Niña Watch based on the possible development of a La […] WeatherBrains | July 23, 2021 0 Comments
La Niña Explained: July, the ENSO, Winter 21/22 and You What do July, the ENSO, and Winter 21/22 all have in common? La Niña, of course! NOAA has just released their prediction for a La Niña winter 20/21. As of July, there is a 55% chance of a La Niña winter, which is great news for the Pacific Northwest and the northern Rockies and not-so-great news for the intermountain region […] Weather Lynn Barlow | July 13, 2021 0 Comments
NOAA July 2021 ENSO Update: La Niña Watch Issued With 55% Chance of Lasting Through Winter As things stand with the El Niño-Southern Oscillation (ENSO), neutral conditions are currently present in the tropical Pacific and favored to last through the North American summer and into the fall. But forecasters at NOAA’s Climate Prediction Center have issued a La Niña Watch, which means they see La Niña likely emerging (~55%) during the September-November period and lasting through […] Weather WeatherBrains | July 8, 2021 3 Comments
NOAA: We Know All About El Niño and La Niña, But What About ‘Pacific Decadal Oscillation’? This post first appeared on the climate.gov ENSO blog and was written by Tom Di Liberto We talk a lot about El Niño and La Niña at the ENSO blog, but there are other phenomena that garner interest among scientists, even if they do not have the same brand recognition as El Niño. So while we wait for a potential […] Weather WeatherBrains | June 3, 2021 0 Comments
