Colin Zarzycki's research is centered around simulating extreme atmospheric phenomena and bridging the gap between weather and climate. In particular, he is focused on cutting-edge, high-resolution modeling techniques. This allows for multiple research directions, including regional weather and climate prediction on timescales ranging from days to decades, the development of dynamical cores and sub-grid physical parameterizations, and software engineering on petascale computing systems. Zarzycki uses these techniques to investigate tropical cyclone dynamics in global climate models and to improve the community's capability to objectively detect weather extremes in "big (climate) data."
