March 2023 ENSO Update: No More La Niña! This article originally appeared on climate.gov La Niña—the cool phase of the El Niño-Southern Oscillation (ENSO) climate pattern—has left the building! After a year and half of non-stop La Niña, the tropical Pacific ocean-atmosphere system has transitioned to neutral, allowing NOAA to issue its “Final La Niña Advisory”. What can we expect for ENSO through the summer and into next […] Weather WeatherBrains | March 9, 2023 0 Comments
NOAA ENSO Update February 2023: La Niña is Weakening – 85% Chance of Neutral Conditions Feb – Apr La Niña—the cool phase of the El Niño-Southern Oscillation climate pattern—weakened over the past month, and forecasters expect a transition to neutral conditions in the next couple of months. We’ll check in with the tropical Pacific to see how things are going before continuing the journey into understanding winter daily temperature variability that I started in December’s post.

NOAA ENSO Update Jan 2023: 82% Chance La Niña Will End by Springtime Sea surface temperatures in the tropical Pacific Ocean from mid-November 2022 through early January 2023 compared to the long-term average. East of the International Dateline (180˚), waters remained cooler than average, a sign of La Niña. Graphic by Climate.gov, based on data from NOAA’s Environmental Visualization Lab.

NOAA ENSO December 2022 Update: La Niña Will Transition to Neutral in Jan-March As our regular readers will be very aware, La Niña has been rolling along in the tropical Pacific for many months, and our third La Niña winter in a row is underway. La Niña is the cool phase of the El Niño-Southern Oscillation (“ENSO” for short) climate pattern. The current forecast is for La Niña to continue into the winter, […] Weather WeatherBrains | December 9, 2022 0 Comments
NASA: La Niña 3 Times – Looking at This Relatively Weak but Unusually Prolonged Event In December 2022, Earth was in the grips of La Niña—an oceanic phenomenon characterized by the presence of cooler-than-normal sea-surface temperatures in the central and eastern tropical Pacific. The current La Niña, relatively weak but unusually prolonged, began in 2020 and has returned for its third consecutive northern hemisphere winter, making this a rare “triple-dip” event. Other triple-dip La Niña’s […] Weather WeatherBrains | December 8, 2022 0 Comments
NOAA ENSO Update: Another Winter in La Niña’s Grip? – November Update to 2022-23 Winter Outlook While it’s a little intimidating to put on these oversized shoes, I’m forging ahead in an annual ENSO Blog tradition and giving you all the juicy details about NOAA’s Winter Outlook (1). Regular readers may remember that Mike Halpert of the NOAA Climate Prediction Center (CPC) has been the blog’s winter outlook guru for years, but following Mike’s retirement earlier […] Weather WeatherBrains | November 23, 2022 0 Comments
NOAA ENSO November 2022 Update: 76% Chance La Niña Continues Through Winter It’s very likely that La Niña will last through the winter (December–February), with a transition to ENSO-neutral (neither La Niña nor El Niño) expected during February–April. Specifically, there’s a 76% chance of La Niña through the winter and a 57% chance of neutral in the February–April period.

NOAA: Where Does Global Warming Go During La Niña? Here at the ENSO blog, we’ve been talking about La Niña (the cool phase of the El Niño-Southern Oscillation climate pattern) for going on three years now. People have started to tell us they’re bored ask us whether all these La Niñas could offset global warming.The short answer is no, La Niña is no match for global warming.
