1. RegCM sensitivity simulations: Land use effects in Eastern Europe Group 15 Mladek, Onol, Tomingas

2. Domain Parameters Grid box: 60x45 Resolution: 50x50 km Central point: 44 N, 35 E Nr. of vertical levels: 18 Data type: ECMWF Map projection: Lambert Conformal Convection scheme: Grell Convection scheme: Grell Closure scheme: Fritsch - Chappell Simulation period: May 1994

3. Simulations Control run (no changes) Control run (no changes) 1: Small lakes replaced with crop/mixed farming 2: Black Sea replaced with crop/mixed farming 3: Irrigation project in Turkey (GAP)

5. Control vs. Analysis

6. Control vs. CRU

7. Experiment 1

9. Experiment 2

12. Vert. Profiles EXP1, EXP2

13. Experiment 3

17. Final Remarks  Small change in land use can trigger quite big response in precipitation (noise)  Without Black Sea precipitation increase (May 1994) (May 1994)  1 month run is not enough to capture climate
