Precipitation - and rain in particular - are important natural phenomena for human life on our planet. We have known for a long time that all water that evaporates from the Earth's surface will eventually return to the surface as precipitation. But which processes or characteristics of the Earth system determine how precipitation gets partitioned between land and ocean? Do fundamental physical laws such as water and energy balance equations constrain this partitioning? How do surface…
Research Interests
I am currently a PhD candidate in the DFG-funded research unit TERSANE II (Temperature related stresses as a unifying principle in ancient extinctions) with the NUC project. My research contributes to the reconstruction of the ocean carbon and nutrient cycles and their interactions with climate during the Permian-Triassic transition. In this context, I am particularly interested in using Earth System Models to bridge the timescales which were present during the…
My research focuses on using next-generation km-scale general circulation models to understand fundamental aspects of various atmospheric circulation systems — ranging from local thunderstorms up to global-scale wind systems. Km-scale models explicitly resolve, rather than parameterize, atmospheric convection and gravity waves, allowing for a much more detailed understanding of these processes and their role in different circulation systems. I’m particularly interested in using my scientific…

Climate system dynamics and climate history are my areas of interest. In particular, I am fascinated by the interaction between the atmosphere and the land surface with its vegetation. What role does this interaction play in the evolution of global and regional climate?
In the early 1990s, I showed that the vegetation-climate system can reach different equilibrium states with…

Under climate change, not all places on Earth warm or cool equally fast, and the pattern of these surface temperature changes controls important aspects of atmospheric circulation and cloudiness ("pattern effect"). Most importantly, the temperature pattern influences the climate feedback parameter and therefore climate sensitivity, i.e., how much Earth changes its temperature in response to radiative perturbations. I research the physical mechanisms of sea surface temperature pattern…

In global storm-resolving models that resolve convection explicitly instead of parameterizing it, microphysical processes are now fundamentally linked to their controlling factors, i.e., the circulation. While in conventional climate models the convective parameterization is one of the main sources of uncertainties (and a popular tuning parameter), this role might be passed on to the microphysical parameterization in global storm-resolving models. In an ongoing project we investigate how…
