The question whether climate change is man-made is discussed in public for a long time. To assess this more accurately and to evaluate future consequences more reliably, it is necessary to understand the underlying physical processes in greater detail. Processes that are linked to the formation of clouds and development of precipitation play an important role within the climate system. Global and regional distribution of clouds and precipitation determine which regions are habitable and which are not, where agriculture can be successful and where not. For answering such questions, the overall target of the BMBF project HD(CP)² is improving the general understanding of cloud and precipitation processes and implications for climate projections. This video shows a simulation carried out by researchers of the Max Planck-Institute for Meteorology (MPI-M) and DKRZ in the context of the BMBF-funded Project "HD(CP)² - High Definition Clouds and Precipitation for Advancing Climate Prediction".
The simulations were carried out on DKRZ's supercomputer Mistral with a special cloud resolving version of ICON, a model jointly developed by the German Weather Service DWD and the MPI-M. The visualizations and the video editing were done by DKRZ.
