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
NOAA March 2021 ENSO Update: Weakening La Niña Unlikely to Develop into El Niño in Fall This post first appeared on the ENSO Blog and was written by Emily Becker La Niña continues in the tropical Pacific, but it has weakened recently, and forecasters estimate about a 60% chance of a transition to neutral conditions in the late spring. Looking farther out into the fall of 2021, El Niño is unlikely to develop, and the chances […] Weather WeatherBrains | March 11, 2021 0 Comments
How Will Climate Change Affect El Niño and La Niña? This post first appeared on the NOAA Research News website As climate change disrupts weather patterns around the world, one overarching question is the subject of increased scientific focus: how it will affect one of the world’s dominant weather-makers?

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
