Rating tornado warnings charts a path to improve forecasts

Tornado in Colorado

The United States experiences more tornadoes than any other country, with a season that peaks in spring or summer depending on the region. Tornadoes are often deadly, especially in places where buildings can’t withstand high winds. Accurate advanced warnings can save lives. A study from the University of Washington and the National Oceanic and Atmospheric Administration describes a new way to rate and possibly improve tornado warnings.

Ask a scientist: Nick Bond

Washington State Climatologist Nick Bond

El Niño and La Niña… we hear these two terms a lot when discussing weather but what do they really mean? We asked Washington State Climatologist and weather enthusiast Nick Bond. Keep reading for more El Niño/La Niña questions that didn’t make it into the video (but are just as interesting!).   View this post on Instagram   A post shared by UW College of the Environment (@uwenvironment) Q: Does El Niño or La Niña really affect our weather?

A stormy disturbance that occurs several times a year in the tropics, the MJO is similar to the El Nino Southern Oscillation, which is notorious for generating extreme winter weather in the Pacific Northwest.

How do we know so much about ancient climates?

Isolab grad student Lindsey Davidge

Scientists know a lot about the Earth’s climate. Over the past sixty years, they have collected temperature and precipitation information, measured the amount of carbon dioxide in Earth’s atmosphere, and charted the changing weather. But what if we want to compare today’s climate to past climates—say, a million years ago or more? Traces of those past climates—referred to as paleoclimates—remain in rocks and ice as particles that once made up the ancient atmosphere, rain and soil.

Atmospheric scientist Chris Bretherton elected to National Academy of Sciences

Chris Bretherton

Chris Bretherton, a University of Washington professor jointly appointed in the departments of Atmospheric Sciences and Applied Mathematics, has been elected to the National Academy of Sciences. He is one of 100 new members elected for their “distinguished and continuing achievements in original research” who were announced April 30 by the academy. Chris studies how clouds form and change over time and how to better represent these processes in global climate and weather-forecasting models.
