Great Lakes Seminar Series: Claire Pettersen

February 7

Winter precipitation (rain and snowfall) has widespread impacts on communities through regional ecology, hydrological planning, and socioeconomic effects. In this presentation, I will feature important findings from winter weather regime-based studies leveraging precipitation observations from a long-term, ground-based instrument suite in the Northern Great Lakes region. Realistic estimates of rain and snowfall in weather forecasting and climate models are challenging due to uncertainties in cloud and precipitation parameterization schemes. Additionally, remote-sensing observations require assumptions about hydrometeor microphysical and radiative properties. High temporal resolution, multi-instrument observations of clouds and precipitation can help better constrain processes in models and refine retrieval assumptions, leading to more accurate quantification of accumulation.
