Research
Dr. Gutowski's research concentrates on the role of atmospheric dynamics in climate. Central focuses are the dynamics of the hydrologic cycle and regional climate. Because processes on a wide range of spatial and temporal scales are important for both of these, his research program entails a variety of modeling and data analysis approaches. His work includes regional modeling of African, Arctic and East Asian climates and has significant collaboration with scientists in these regions. Much of his work is through the Regional Climate Modeling Laboratory (PIRCS), which he coordinates with Dr. Eugene Takle and Dr. Ray Arritt (Agronomy Department).
