About Us


Atmospheric Sciences at UWM began in the late 1960s in the College of Engineering and Applied Sciences and the College of Letters and Science’s Dept. of Geography. The first M.S. and Ph.D. recipients with concentrations in atmospheric sciences graduated in 1968 and 1972, respectively. Noteworthy faculty during this time include world-renowned climate dynamicist Stefan Hastenrath; broadcast legend Walt Lyons; and Werner Baum, who served as UWM’s Chancellor between 1973-79 and as the President of the American Meteorological Society in 1977.

In the late 1970s, UWM’s programs in the atmospheric sciences moved to the College of Letters and Science’s Dept. of Geosciences. Our undergraduate major began in the late 1970s as an option to the Geosciences major and became its own major in 1999. Distinguished Professor Emeritus Anastasios Tsonis joined the faculty in 1985, and under his direction the program steadily grew through the 1990s. Current faculty members Jon Kahl and Paul Roebber were hired in 1990 and 1994, respectively.

In 2000, UWM’s programs in the atmospheric sciences moved to the College of Letters and Science’s Dept. of Mathematical Sciences. It is here in which our Innovative Weather program began in 2007, and the nation’s first faculty-led study-abroad program in the atmospheric sciences, “Air Pollution and Ancient Cultures,” began in 2010. And, after nearly 50 years as options to other programs’ graduate degrees, our standalone Atmospheric Sciences M.S. and Ph.D. programs began in 2017. Affiliated faculty member Vince Larson was hired in 2001, and current faculty members Sergey Kravtsov and Clark Evans were hired in 2005 and 2011, respectively.

Complaints and Reporting Policies

The UWM Atmospheric Sciences Program is committed to supporting students who experience microaggressions, harassment, discrimination, and/or overt racism or sexism by providing clear complaints and reporting policies. In general, we refer students to the university-wide reporting policies for discrimination — the full UWM discriminatory policy is available here. Complaints can be made in-person at UWM’s Office of Equity/Diversity Services or via phone/email. Anonymous reports are permitted, and additional resources available to students include counseling services, student centers, and other university resources. Students are also encouraged to reach out to us — the Atmospheric Sciences faculty are committed to being your advocates.
