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).

Mteor 404/504 - Global Change Recent changes in global biogeochemical cycles and climate; models of future changes in the climate system; impacts of global change on agriculture, water resources and human health; ethical issues of global environmental change. (Cross-listed with Agron, Env S, EnSci, online version of 404 offered alternate years)

Mteor 452/552 - Physics of Climate Exploration of the fundamental physical principles that govern climate systems of the earth and other planets. Emphasis on coupled, nonlinear-system interactions of physical processes, starting with fairly simple 0- and 1-dimensional analytical and numerical models. Virtual classroom environment for linking with students at other universities, in part through lab sessions on climate modeling. Further sessions on the observed, seasonally evolving weather patterns that form climates, to complement theory development.

Mteor 454 - Dynamic Meteorology II Planetary boundary layer, linear perturbation theory, atmospheric wave motions, baroclinic and convective instability, mesoscale circulations.
