The COrdinated Regional climate Downscaling EXperiment is a framework
devoted to coordinate international efforts on regional climate
simulations. In the first phase of CORDEX, Africa has been selected as
the key region with the aim to improve the knowledge on climate change
impacts in the continent. The results of a kick-off experiment with the
WRF-ARW model are presented. A sensitivity test on different physical
parametrisations for annual simulations of the African continent was
carried out. The domain covers the whole African continent (aprox.
50S-50N, 30W-92E) with a horizontal resolution of 50 km and 26 vertical
levels. The simulation results are validated with surface observations
and TRMM satellite monthly precipitation rates. This study is a first
step toward the selection of physical parameterizations to be run in the
long term to produce CORDEX-compliant simulations for Africa using WRF.
