Biographical Summary

Wolfgang Langhans is a postdoctoral fellow working with David Romps.  His research focuses on the dynamics and thermodynamics of convective clouds.  In particular, he studies the precipitation efficiency of such clouds using cloud-resolving and large-eddy simulations.
He received his Diploma degree in Meteorology and Geophysics from the University of Innsbruck, Austria. During his studies he developed a keen interest in theoretical meteorology, mountain meteorology, and mesoscale numerical weather prediction. His research under the guidance of Alexander Gohm addressed the role of microphysics parameterizations for the numerical prediction of Alpine heavy precipitation events.
Wolfgang obtained his PhD from ETH Zurich, Switzerland, where he worked under the guidance of Christoph Schär on cloud-resolving modeling of orographic convection. During his PhD he published research on the convergence of cloud-resolving simulations, on the impact of explicit numerical diffusion, and on thermally-driven valley-flows. He also developed an interest in large-eddy simulations and their application to atmospheric convection. His current research focus is on the precipitation efficiency of clouds, a key parameter to many convection parameterizations.
