21st Century Climate in Africa: Regional Climate Simulations with COSMO-CLM

Visualization of end of the century climate change signal of the ensemble mean for the RCP8.5 simulations (2070-2099 minus 1971-2000). Left: temperature change in °C, right: precipitation change in mm/year.

The African Continent will be severely hit by climate change. A necessary building brick for counteraction are reliable projections of the African climate of our century. The CORDEX CORE initiative is designed to provide such information for the CORDEX CORE regions, among them CORDEX CORE Africa. IMK-TRO contributed to this with an ensemble of presently ten regional climate simulations performed on the Hazel Hen at HLRS Stuttgart. Results indicate dramatic changes especially in precipitation. The simulations presented here will be part of the IPCC AR6 atlas of regional climate change and the CORDEX data repository. They will be freely available for impact, adaptation and mitigation studies.
