Job description:

Future changes in cloud properties and extreme precipitation are of great societal importance, particularly in areas affected by the Monsoon circulation. New high resolution models allow the relevant processes to be much better represented than in the past and have been shown to lead to significant improvements in the simulation of precipitation and circulation. Nevertheless, these models need to be carefully evaluated against observational data, in particular regarding small scale processes such as cloud microphysics.

In this PhD project new global storm resolving (sub 4 km) simulations will be analyzed with focus on the upper tropospheric water budget in the current and future climate. Large improvements simulating dynamics and cloud and precipitation processes have been demonstrated in storm resolving simulations while the representation of ice cloud properties remains problematic. You will analyze ice cloud properties in storm resolving (SRM) simulations performed by the DYAMOND project and simulated by ICON-SRM at 2.5 km resolution by the project partners at the MPI for Meteorology and DKRZ in Hamburg and project partners in China. Simulations will be evaluated with observational data from passive and active remote sensing in cooperation with DLR scientists. You will explore the sensitivities of large-scale simulations to the representation of microphysical processes and perform lower resolution sensitivity simulations with ICON-SRM ensuring a best possible representation of ice cloud properties.  Within simulations for a future climate you will analyze the impact of climate change on the upper tropospheric water budget and its possible consequences for precipitation processes.
