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: 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
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 ENSO Blog: The Rise of El Niño and La Niña This post first appeared on the climate.gov ENSO blog and was written by Michelle L’Heureux We often get asked how El Niño or La Niña events form and increase in strength. The key is in the ocean-atmosphere coupling across the tropical Pacific Ocean. Without it, ENSO would not exist, and it would be considerably more difficult to predict climate impacts seasons in advance. […] Weather WeatherBrains | October 30, 2020 1 Comment
