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.

UW students win national weather forecasting contest

Faculty lead Lynn McMurdie, center, and some of the students from the winning UW team pose on the roof of the Atmospheric Sciences-Geophysics Building.

  The University of Washington has won a national competition in which colleges vie to deliver the most accurate daily forecast for cities across the country. A UW student also developed a machine-learning model that for the first time delivered a more accurate forecast than any human competitor. In results announced this week, the UW team placed first among 36 teams in the annual WxChallenge operated by the University of Oklahoma.

Washington’s state climatologist comments on Puget Sound snowstorm

Snow on the UW campus

After many people in the Puget Sound region had dismissed any chance of snowfall in the lowlands this season, the region is now on track for not one, but two, and possibly even more snowstorms this winter. Nick Bond, a University of Washington associate professor of atmospheric sciences who serves as Washington’s official state climatologist, commented Thursday on the upcoming snowstorm – the second to hit the Puget Sound region this week.
