Drops forming on the outside of your drink don’t just make the can slippery. Experiments show that in hot, humid weather, condensation heats a drink more than the surrounding air.
One of the most persistent biases in global climate models is due to poor simulation of cloud cover thousands of miles to the south.
Regional cloud changes may be as important for climate change as the overall amount of cloud cover.
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.
A new international assessment found that soot, or black carbon, is a major contributor to global warming — second only to carbon dioxide.
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.
Microorganisms – 99 percent more kinds than had been reported in findings published just four months ago – are hitching rides in the upper troposphere from Asia.
UW scientists are teaming with the U.S. Coast Guard to study the new frontier in the Arctic Ocean opened up with the melting ice.
A University of Washington scientist has proposed an experiment to test cloud brightening, a geoengineering concept that alters clouds in an effort to counter global warming.
