Climate and water cycle analysis for Bavaria using extremely high-resolution regional earth system modeling
The regional water cycle is mainly determined by vegetation, soil, terrain and the
driving atmospheric circulation. Both its short-term and climate-related long-term changes can only be understood with the aid of complex numerical simulations, which take into account in particular small-scale structures. Such a spatially extremely high-resolution simulation is in the focus of subproject 8. Three carefully interconnected computer models for the atmosphere, the land surface and the soil are being developed, combined into a single regional earth system model and operated in very high spatial resolution. This allows us to dynamically regionalise global climate scenarios by simulating all hydrologically relevant processes on a time- and space scale adapted to the target region of Bavaria.
Regional Earth System Modeling in LandKlif: Fully coupled simulation of the atmospheric and terrestrial water balance.
Through the high-resolution regionalization 1) of a long-term global simulation of the past (serving for validation), and 2) a global climate scenario simulation (describing the expected climate change in the future), for the region of Bavaria a unique data set is developed for climate- and hydrological research and the delineation of adaption measures. This forms a central basis for ecosystem-related climate change impact research in the collaborative project.
