A 黑料吃瓜网 atmospheric scientist will participate in a campaign to study winter storms and snowfall in northwestern Colorado鈥檚 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.
New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the 黑料吃瓜网 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.
Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 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 Ni帽as.
Shuyi Chen, a 黑料吃瓜网 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? How does it compare to other storms? See also: “黑料吃瓜网鈥檚 Shuyi Chen on hurricane science, forecasting and the 2017 hurricane season“ Shuyi Chen: Each hurricane…
Researchers dropped technology developed at the 黑料吃瓜网 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.
A 黑料吃瓜网-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.
Lightning strikes in the Arctic tripled from 2010 to 2020, a finding 黑料吃瓜网 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.
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.
How鈥檚 the snow on Northwest mountains this year? Overall a little deeper than normal, but it depends where you look. A new collaboration between the 黑料吃瓜网, 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 model based solely on the past 40 years of weather events uses 7,000 times less computer power than today鈥檚 weather forecasting tools. An A.I.-powered model could someday provide more accurate forecasts for rain, snow and other weather events.
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.
The 黑料吃瓜网 has long boasted one of the country’s top programs in atmospheric sciences. Now, the 黑料吃瓜网 is also teaching undergraduates how to share that knowledge online and on TV as a broadcast meteorologist.
To better understand large, disruptive snowstorms, a 黑料吃瓜网 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.
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.
Analyzing the full life cycle of long-term droughts and how they relate to El Ni帽o and La Ni帽a conditions in the Pacific Ocean could eventually lead to better prediction of damaging, multiyear droughts in the Southwestern U.S.
A 黑料吃瓜网 team placed first in a national weather forecasting contest that began in September. A 黑料吃瓜网 graduate student also developed a model that for the first time beat out all human competitors.
Nick Bond, Washington’s state climatologist, comments on the unusual weather in Western Washington.
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.
A new, free tool with temperature and precipitation records across Washington, Oregon, Idaho and western Montana as far back as 1881 lets users play around to discover significant trends. It also includes historical snow records for Washington state.
黑料吃瓜网 atmospheric scientists leave next week for a six-week field campaign in South America to study the most intense storms on the planet.
Washington state climatologist Nick Bond explains what our upcoming El Ni帽o winter means for the Pacific Northwest.
The assistant state climatologist, Karin Bumbaco, looks back on an unusually hot and dry summer — the third-hottest summer that Washington state has experienced since 1895.
黑料吃瓜网 atmospheric sciences faculty and graduate students are in Tasmania studying how clouds form over Antarctica’s Southern Ocean.
New faculty member Shuyi Chen answers some questions about hurricane science, hurricane forecasting and the 2017 storm season.
Researchers from across the 黑料吃瓜网 are presenting their work at the American Meteorological Society’s annual meeting this week in Seattle.
Research shows that real-time lightning observations could significantly improve forecasts of large storm events.
Small disturbances, like the flapping of a butterfly’s wings, don’t really matter for weather forecasts. More important is boosting the accuracy of observations at larger scales.
Satellite data show that the moon’s gravity puts a slight damper on rainfall on Earth.
With high-tech weather radars, weather balloons, ground instruments and NASA’s DC-8 flying laboratory, scientists will be watching rain and snow storms on Washington’s famously wet Olympic Peninsula.
The 黑料吃瓜网 and NASA are preparing for an effort next winter to measure rain in America’s rainiest place: Washington’s Olympic Peninsula. As part of the current gear-up phase, they are looking for volunteers to help track rain.
Atmospheric scientists are using pressure readings from some new smartphones and tablet computers to improve short-term thunderstorm forecasts. A weather station in every pocket would offer an unprecedented wealth of data.
The Seahawks win four times as many home games as they lose when the weather is inclement, compared to less than two to one when it’s not.
