2. A.Montani; Eurorisk-Preview COSMO meeting, Zurich, 20-23 September 2005 Provision of probabilistic forecasts and warnings of strong wind events at all time ranges up to 10 days ahead. Windstorms Workpackage (DWD, ARPA-SIM) Ensemble Forecast inputs: –Medium-Range (3-10 days) ECMWF ARPA-SIM (COSMO-LEPS) (Days 3-5) –Short-Range (1-2 days) – multi-model ensemble consisting of contributions from: Meteo-France - PEACE DWD - SRNWP-PEPS Met.no - TEPS/LAM EPS Met Office - LAMEPS/EPS Post-processing…

3. A.Montani; The COSMO-LEPS system: recent developments and plans 2nd Workshop on Short-Range EPS, Bologna, 7-8 April 2005 Clone of COSMO-LEPS suite over NW Europe  Generation of a new limited-area ensemble forecast system for the prediction of wind and wind gusts over North-Western Europe.  Aim: provision of site-specific wind forecasts to be post-processed and combined with other products by UK Met. Office.  Same configuration as the operational COSMO- LEPS (red), but both clustering and integration domain are shifted northwards (blue). Experimental suite will start on June 2006. Computer time provided by an ECMWF special project between ARPA-SIM and UK Met Office.

4. A.Montani; The COSMO-LEPS system: recent developments and plans 2nd Workshop on Short-Range EPS, Bologna, 7-8 April 2005 Provision of probabilistic forecasts so as to generate ensemble flood forecasts to be compared with the deterministic approach for ranges between 3 and 10 days.  The upper-Danube river basin has been selected as pilot river basin and the test period will include the large floods of August 2002. Medium-range plain flood Workpackage (DWD, ARPA-SIM) Very short-range high-resolution flash-flood Workpackage (ARPA-Piedmont, Meteoswiss) Prepare the use of next-generation NWP models for hydrological applications in flash-flood forecasting over medium basins. Establish the know-how for developing hydrometeorological coupled model systems for flash-flood forecasting.
