Davide Panosetti is a postdoctoral researcher in the Climate and Water Cycle group at ETH Zurich led by Prof. Dr. Christoph Schär. His research addresses the convergence behavior and resolution sensitivity of convection-resolving models at horizontal grid spacings ranging from 8 km to 500 m. In particular, he compares structural convergence of statistics and scales of individual clouds and updrafts with bulk convergence of domain-averaged and integrated properties related to large ensembles of convective cells. To this aim, he runs v5.0 of the model of the Consortium for Small-Scale Modeling in both idealized and real-case setups. He focuses on the diurnal cycle of convection over land, primarily over mountainous terrain.
In his poster he demonstrates that bulk convergence is systematically observed at convectionresolving scales in idealized simulations, and less rigorously in real-case simulations over mountainous terrain. On the other hand, structural convergence is not yet achieved at the kilometer scale.
