1 Trieste, October 2008, Lorenzo Tomassini, MPI-M Research directions in regional climate modeling of the Mediterranean at MPI-M Daniela Jacob, Alberto Elizalde, and Lorenzo Tomassini Max Planck Institute for Meteorology, Hamburg

2 Trieste, October 2008, Lorenzo Tomassini, MPI-M Overview 1. Hydrological cycle including extremes 2. Atmospheric circulation 3. Regional feedbacks Three major research areas:

3 Trieste, October 2008, Lorenzo Tomassini, MPI-M Overview Hydrological cycle in the Mediterranean: A coupled atmosphere-ocean regional climate model Droughts Extreme precipitation events

4 Trieste, October 2008, Lorenzo Tomassini, MPI-M Coupled regional model Ph.D. project of Alberto Elizalde: Working model for Mediterranean climate Assessment of hydrological cycle Better understanding of processes involved Reproduce ocean-atmosphere feedbacks Analyze the impact of the coupled system on climate simulations Perform climate change simulations

5 Trieste, October 2008, Lorenzo Tomassini, MPI-M Coupled regional model Atmosphere Model (REMO) Hydrological Model (HD model) Coupler (OASIS 3) Ocean Model (MPI-OM)

6 Trieste, October 2008, Lorenzo Tomassini, MPI-M Droughts Max no. of cdd

7 Trieste, October 2008, Lorenzo Tomassini, MPI-M Droughts No. of dry periods (cdd > 5 days)

8 Trieste, October 2008, Lorenzo Tomassini, MPI-M Droughts Drought index dsi3 for A1B scenario and (two arbitrary grid boxes: nord and south)

9 Trieste, October 2008, Lorenzo Tomassini, MPI-M Extreme precipitation events Increase in heavy rainfall for a) Observations b) REMO control I c) REMO control II d) REMO B1 scenario e) REMO A1B scenario f) REMO A2 scenario

10 Trieste, October 2008, Lorenzo Tomassini, MPI-M Extreme precipitation events Result of t-test for: a) Observations b) REMO control I c) REMO control II d) REMO B1 scenario e) REMO A1B scenario f) REMO A2 scenario
