Lightning is one of the most destructive forces of nature, as in 2020 when it sparked the massive California Lightning Complex fires, but it remains hard to predict. A new study led by the University of Washington shows that machine learning — computer algorithms that improve themselves without direct programming by humans — can be used to improve lightning forecasts. Better lightning forecasts could help to prepare for potential wildfires, improve safety warnings for lightning and create more accurate long-range climate models.

In pre-COVID times, a group of students would huddle around a computer practicing their skills to create professional-grade weather graphics like the ones seen on local news channels or practice giving weather reports while standing in front of a green screen in a mini-TV-studio classroom. They are part of The UW DawgCast, a year-long club offered in the Department of Atmospheric Sciences jointly with a broadcast meteorology course that welcomes weather-loving students of all majors to teach them how to read, synthesize, and communicate weather.

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.
