RegCM sensitivity simulations: Land use effects in Eastern Europe Group 15 Mladek, Onol, Tomingas
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
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)
Control vs. Analysis
Control vs. CRU
Experiment 1
Experiment 2
Vert. Profiles EXP1, EXP2
Experiment 3
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
