ABSTRACTIn the present study the spatial and temporal variability of the Aridity Index (AI) over the Mediterranean, is analyzed per decade, during the 30-year period (1971-2000). Besides, the projected changes in ensemble mean AI between the period 1971-2000 (reference period) and the periods 2031-2060 (near future) and 2071-2100 (far future), based on the simulation results, derived from21 Regional Climatic Models (RCMs), from the CORDEX EU project are presented. The projection of the future climate was done under RCP4.5 and RCP8.5. Additionally for the reference period, daily precipitation totals as well as mean air temperature from the E-OBS gridded climatic data are used. The estimation of the AI was carried out based on the potential evapotranspiration (PET) defined by Thornthwaite (1948). The future projections at the end of twentieth century, based on the ensemble mean simulations from 21 RCMs, show that drier conditions are expected to establish in Spain, Italy, Bulgaria, Greece, Turkey as well as in the North Africa.
