David B Mechem

David B. Mechem is the Chair Professor in the Department of Geography at the University of Kansas, specializing in Atmospheric Science. His research focuses on cloud microphysics, mesoscale organization of cloud systems, and the dynamics of precipitating convection. He teaches courses in dynamic meteorology, physical meteorology, and numerical modeling. His work integrates observational data with large-eddy simulation, cloud-resolving models, and mesoscale models to study cloud processes in marine boundary layers and stratocumulus systems.

Research interests include cloud-system interactions, aerosol effects on precipitation, and the mechanisms governing rapid cloud clearing in subtropical regions. Key projects involve analysis from field campaigns like GoAmazon2014/5 and ACE-ENA, exploring cloud-eroding boundaries and microphysical parameterization uncertainties. He has contributed to understanding mesoscale organization's role in upscale energy transfer and climate feedbacks.

Publications span cloud dynamics, aerosol-cloud interactions, and climate modeling, with a focus on marine stratocumulus and cumulus systems. His research emphasizes bridging observational data with high-resolution simulations to address climate model discrepancies.

Teaching responsibilities include undergraduate and graduate courses in meteorology, emphasizing numerical methods and physical processes. His lab's work has implications for improving climate model accuracy and understanding atmospheric energy transfers.
