Dr. Sulia's work within ice microphysics focuses on crystal growth theory as a means to improve microphysical parameterizations within numerical models. Ice particles grow in interesting and complex fashions, and the mechanisms of vapor diffusional growth are highly dependent on the myriad of ice crystal shapes that occur within the atmosphere. Ice crystal shape can have important impacts on mixed-phase cloud evolution and lifetime, precipitation rates, and surface radiative and energy budgets which can affect surface temperatures, and when in the Arctic, sea-ice extent. Ice particle shape also impacts collection processes, such as riming and aggregation, which enhance surface precipitation. Improving the representation of these processes is critical for accurate predictions of precipitation, especially in winter storms. Recent and continuing upgrades of North American radars to dual-polarization provides.
