A validation analysis of the Spanish peninsular seasonal precipitation at a resolution of 25 km (1961-2000 period) simulated by 11 regional climate models forced with ERA40 lateral boundary conditions is presented. The models derive from the ENSEMBLES project. Validation was conducted using MOPREDAS dataset to take advantage of its high spatial density and its long temporal period covered (1946-2005), necessary for the purpose of validation of high-resolution regional climatic simulations. Results suggest that, generally, the multi-model mean performs better in central and western Spain especially during winter season, and worse during summer and along the Mediterranean fringe. The most probable reasons of such a spatial and temporal distribution are discussed. All models are able to reproduce the NAO atmospheric pattern, which is especially influent in the central and western Spain, however they fail to reproduce other important patterns, particularly in the areas where the performance of the models is already low. Finally, some implications of model predictions in areas where accuracy is low are discussed.
