UW atmospheric scientist participating in field campaign to improve Western snowfall, drought forecasts
A UW atmospheric scientist will participate in a campaign to study winter storms and snowfall in northwestern Colorado’s Rocky Mountains. Like Seattle, this area depends on winter snow for its summer water supplies, so improving mountain snow forecasts will improve projections for summer drought and wildfire risks.

Strongest Arctic cyclone on record led to surprising loss of sea ice
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the University of Washington shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest how forecast models for a changing Arctic Ocean could improve.

Study suggests La Niña winters could keep on coming
Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Niñas.

UW expert on tropical storms discusses Hurricane Ian
Shuyi Chen, a UW professor of atmospheric sciences, was traveling to a conference in Boston as Hurricane Ian approached the Gulf of Mexico. During breaks at the conference, she provided her thoughts on the closely watched catastrophic storm system that made landfall in Florida on Sept. 28. Q: What are your thoughts on Hurricane Ian?…
UW-developed wave sensors deployed to improve hurricane forecasts
Researchers dropped technology developed at the University of Washington off the coast of Florida this week to measure ocean waves in the path of Hurricane Ian. The test is one part of a broad effort to improve forecasts for these fast-moving and deadly systems.

Remotely-piloted sailboats monitor ‘cold pools’ in tropical environments
A UW-led study uses data from remotely-piloted sailboats to better understand cold air pools — pockets of cooler air that form when rain evaporates below tropical storm clouds. These fleeting weather phenomena are thought to influence tropical weather patterns.

Warming temperatures tripled Arctic lightning strikes over the past decade
Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes.

Rating tornado warnings charts a path to improve forecasts
A new method to rate tornado warnings shows that nighttime tornadoes in the U.S. have a lower probability of detection and a higher false-alarm rate than other events. Summertime tornadoes, occurring in June, July or August, also are more likely to evade warning.

Online tool displays Pacific Northwest mountain snow depth
How’s the snow on Northwest mountains this year? Overall a little deeper than normal, but it depends where you look. A new collaboration between the University of Washington, the Northwest Avalanche Center lets you see how the current snow depth compares to past years for nine sites in Washington and two in Oregon.

A.I. model shows promise to generate faster, more accurate weather forecasts
A model based solely on the past 40 years of weather events uses 7,000 times less computer power than today’s weather forecasting tools. An A.I.-powered model could someday provide more accurate forecasts for rain, snow and other weather events.

Are climate scientists being too cautious when linking extreme weather to climate change?
Climate science has focused on avoiding false alarms when linking extreme weather to climate change. But when meteorologists warn of hazardous weather, they include a second key measure of success — the probability of detection.

UW scientist to lead NASA field study of East Coast snowstorms
To better understand large, disruptive snowstorms, a University of Washington atmospheric scientist will lead a NASA field campaign this winter to fly through major snowstorms along the East Coast. The multi-institutional team will observe snow as it forms in clouds to help with satellite monitoring of snowfall and ultimately improve forecasts.

Lightning ‘superbolts’ form over oceans from November to February
A study of superbolts, which release a thousand times more electrical energy in the low-frequency range than regular lightning bolts, finds they occur at very different times and places than regular lightning. Superbolts tend to strike over particular parts of the oceans, while regular lightning strikes over land.

How the Pacific Ocean influences long-term drought in the Southwestern U.S.
Analyzing the full life cycle of long-term droughts and how they relate to El Niño and La Niña conditions in the Pacific Ocean could eventually lead to better prediction of damaging, multiyear droughts in the Southwestern U.S.

For 35 years, the Pacific Ocean has largely spared West’s mountain snow from effects of global warming
A new study has found that since the early 1980s, a pattern of ocean temperatures and atmospheric circulation has offset most of the impact of warming on the West’s mountain snowpack.
