Current Research

The incomplete understanding of the local dynamics of the stratocumulus top underlies key uncertainties in climate modeling. My current project aims to investigate this local dynamics. Previous work within the research group “Turbulent Mixing Processes in the Earth System” has considered the role of radiative and evaporative cooling in the vertical structure of the stratocumulus top region, and in the mean entrainment velocity. In my ongoing project, this work is extended by investigating the interactions between steady and unsteady wind shear, droplet sedimentation, radiative cooling, and evaporative cooling. The role of wind shear and droplet sedimentation has often been ignored in the analysis, but recent work has shown that it can be critical. A related newspaper article can be found here.
