NOAA ENSO Blog: Why Making El Niño Forecasts in the Spring Is Especially Anxiety-Inducing Given the relatively high probabilities for El Niño in our team’s April 2023 ENSO update, I decided to team up with some of my scientific colleagues, Antonietta Capotondi (NOAA Physical Sciences Laboratory and University of Colorado, Cooperative Institute for Research in Environmental Sciences) and Aaron Levine (@afzlevine, University of Washington, Cooperative Institute for Climate, Ocean, and Ecosystem Studies), to explain why […] Weather WeatherBrains | May 8, 2023 0 Comments
Is a “Super El Niño” Event Coming? As most of you are probably aware, El Niño and La Niña are sea surface temperature oscillation events over the southern Pacific Ocean that can impact weather patterns worldwide. According to the National Ocean Service, during El Niño, trade winds from the Pacific weaken and warm water is pushed from the east to the west coast of the Americas. A shift […] Weather Zoe Loftin | April 14, 2023 0 Comments
NOAA ENSO April Update: 62% Chance of El Niño Conditions for May–July Well, that was quick! Just two months ago I was writing about La Niña for what seemed like the 97th month in a row, and then by March La Niña had departed. Today we’re hoisting an El Niño Watch, meaning that conditions are favorable for the development of El Niño conditions within the next 6 months. In fact, there’s a […] Weather SnowBrains | April 13, 2023 0 Comments
Atmospheric Rivers: How They Work, and How El Niño and La Niña Affect Them This article was originally published on climate.gov When rivers reach the sky Guest co-author Dr. Kai-Chih Tseng is a postdoctoral research scientist at Princeton University and the NOAA Geophysical Fluid Dynamics Laboratory who is an expert on climate variability and prediction, including the study of atmospheric rivers. In the summer of 2022, Dr. Tseng will begin an assistant professor position in the Department of Atmospheric […] Weather WeatherBrains | January 5, 2023 0 Comments
How Does El Niño-Southern Oscillation (ENSO) Affect Salmon? This article was originally published on climate.gov When we discuss the El Niño-Southern Oscillation (“ENSO” for short) at the blog, we often take a rather human or physics-y view of the climate phenomenon. We’ve published loads of articles discussing the mechanics for how ENSO works in the atmosphere and the ocean, and how ENSO impacts humans from droughts and wildfires […] Weather WeatherBrains | August 11, 2022 0 Comments
NOAA: July 2022 ENSO Update – 66% Chance of a La Niña Winter, ~5% Chance of El Niño Winter I’m in San Diego this week, gazing out across the Pacific toward La Niña’s cool tropical ocean surface. (I’m not here for Comic-Con, but there are a lot of posters around the city that keep that upcoming event in the forefront.) Just over my horizon, La Niña—the cool phase of the El Niño-Southern Oscillation (“ENSO” for short)—remains in force, despite […] Weather WeatherBrains | July 15, 2022 0 Comments
NOAA June 2021 ENSO Update: Too Early to Predict La Niña for 21/22, <10% Chance of El Niño This post first appeared on the climate.gov ENSO blog and was written by Emily Becker ENSO-neutral conditions are present in the tropical Pacific, and NOAA forecasters think they’re likely to continue through the summer. Neutral is slightly favored through the fall, although it’s a close call between continued neutral and re-developing La Niña for the late fall and winter.

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
