Research Profile

Modeling and solving complex physical systems described by partial differential equations poses many challenges to mathematicians and practitioners. Typically, different parts of the system are modeled by processes that interact on various spacial and temporal scales. Simulations of such systems, e.g., climate simulations, is extremely challenging.

Since every numerical simulation possesses a truncation scale important subgrid processes can not be resolved and must be taken care of by different means, e.g., by so-called parametrizations. The coupling between parametrized processes and the computational model (e.g., the dynamical core) is, however, often just heuristic. For reliable simulations, in particular over long time, coupling strategies to the (main) computational model/scale are essential.
