Résumé
This paper synthesizes the main results of the EU funded CIRCE project which main objective was the investigation and analysis of the Mediterranean climate under present and future scenario conditions, by means of numerical simulations. A plethora of climate models, ranging from global to regional, participated to CIRCE, with the common feature of an interactive high-resolution module, for the realistic simulation of the Mediterranean Sea dynamics. Model results show a realistic representation of the observed spatial patterns of the 2 meter-temperature and precipitation, despite quite substantial biases. Heat and mass fluxes over the Mediterranean basin are realistically simulated. The CIRCE projections for the twenty-first century suggest that remarkable changes in the climate of the Mediterranean region might occur already in the next few decades, with a tendency toward a warmer and dryer climate.
