THIS WORK WILL APPLY THE LAGRANGIAN DIAGNOSIS METHOD USED BY STOHL AND JAMES (2004, 2005) AND USED RECENTLY ALSO BY NIETO ET AL, (2006, 2007) TO IDENTIFY THE MAIN NET UPTAKE OF MOISTURE IN AIR MASSES RESIDING OVER AN EXTENDED MEDITERRANEAN AREA, THE LAGRANGIAN APPROACH USED IN THE NUMERICAL METHODOLOGY WILL CONTRAST WITH THE TRADITIONAL EULERIAN APPROACHES, AND COMPARISONS WILL PROVIDE INTERESTING INFORMATION, IT GIVES A COMPLEMENTARY APPROACH TO THE SIMULATION OF THE ATMOSPHERIC TRANSPORT ON THE MEDITERRANEAN BASIN, BY USING TWO SUPERCOMPUTERS WHERE THE RESEARCH GROUPS HAVE GOOD/PREFERENTIAL ACCESS (MARENOSTRUM/FINISTERRARE) THE ANALYSIS WILL BE EXTENDED TO THE WHOLE ERA REANALYSIS TEMPORAL DOMAIN (1957-2002) WHAT WILL PERMIT TO STUDY ALSO THE INTERANNUAL VARIABILITY AND TRENDS OF THE MOISTURE SOURCES, BOTH IN POSITION AND INTENSITY, BY USING THE STATE OF THE ART WHOLE ATMOSPHERE MODEL WACCM WE WILL ALSO STUDY THE SOURCE OF MOISTURE FOR THE MEDITERRANEAN REGION IN A FUTURE CLIMATE, TWO PERIODS OF INTEGRATION (2021-2050 AND 2071-2100) AND TWO SCENARIOS OF CLIMATE CHANGE (A2 AND B2) WILL BE STUDIED IN THE PROJECT, THE STUDY WILL PERMIT TO ANSWER IMPORTANT QUESTIONS ABOUT THE ATMOSPHERIC BRANCH OF THE HYDROLOGICAL CYCLE IN THE MEDITERRANEAN SUCH AS THE STATIONARITY OF THE SOURCES ALONG THE YEARS, THE EFFECT OF THE INCREMENT OF SURFACE TEMPERATURE IN THE MOISTURE SOURCES, THE ROLE OF MAJOR MODES OF CLIMATE VARIABILITY IN THE POSITION AND INTENSITY OF THE SOURCES OR WHAT IT IS EXPECTED ABOUT THE SOURCES IN A CHANGING CLIMATE,NIETO, R,, L, GIMENO, AND R, M, TRIGO, 2006: A LAGRANGIAN IDENTIFICATION OF MAJOR SOURCES OF SAHEL MOISTURE, GEOPHYSICAL RESEARCH LETTERS 33, L18707, DOI: 10,1029/2006GL027232,NIETO, R,, L, GIMENO, D, GALLEGO AND R, M, TRIGO, 2007: CONTRIBUTIONS TO THE MOISTURE BUDGET OF AIRMASSES OVER ICELAND, METEOROLOGISCHE ZEITSCHRIFT 16, NO, 1, 037-044, DOI: 10,1127/0941-2948/2007/0176STOHL, A,, P, JAMES, 2004: A LAGRANGIAN ANALYSIS OF THE ATMOSPHERIC BRANCH OF THE GLOBAL WATER CYCLE, PART 1: METHOD DESCRIPTION, VALIDATION, AND DEMONSTRATION FOR THE AUGUST 2002 FLOODING IN CENTRAL EUROPE, J, HYDROMETEOR, 5, 656¿ 678,STOHL, A,, P, JAMES, 2005: A LAGRANGIAN ANALYSIS OF THE ATMOSPHERIC BRANCH OF THE GLOBAL WATER CYCLE: 2, EARTH¿S RIVER CATCHMENTS, OCEAN BASINS, AND MOISTURE TRANSPORTS BETWEEN THEM, J, HYDROMETEOR, 6, 961¿984, FUENTES DE HUMEDAD\APROXIMACIONES LAGRANGIANAS\MEDITERRANEO\VARIABILIDAD INTERANUAL
