Cluster analysis results of regional climate model simulations in the PIDCAP period

On the basis of an extended cluster analysis algorithm, a new validation method is presented for the quality control of climate model simulation results. To test the method, a comparison of four climate model simulation runs was carried out, comprising on the one hand results of the non-hydrostatic model (LM) of the German Weather Service (DWD) and on the other hand results of a hydrostatic model (REMO) of the Max-Planck-Institute for Meteorology, Hamburg (MPI). The results of the cluster analysis show that the method is suitable to describe the differences between reference and simulation data in space and time.
