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…

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.

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.
