1. Activities of the new WG7 Chiara Marsigli

2. WP 7.1 - Development of COSMO-LEPS Maintenance and updates of the operational suite at ECMWF (A. Montani) Study, development and implementation of new clustering and member selection techniques (A. Montani) –Mainly for short-range forecast Testing the use of different sources for the initial conditions of soil fields (“soil merge”) (A. Montani, A. Walser) –Completed. Now COSMO-LEPS runs with COSMO-EU soil Generation of calibrated COSMO-LEPS forecasts (T. Diomede) –Formerly part of CONSENS PP –Calibrated QPF will be operationally distributed by the end of the year (only for subdomains!) Tests for the LAM-EPS BC project (A. Montani)

3. WP 7.2 - Development of an ensemble system for the Sochi olympic games Part of CORSO PP

4. WP 7.3 - Perturbation of the surface fields Formerly part of CONSENS PP (HNMS task) A technique for soil-moisture perturbation for COSMO has been developed First tests are on-going The work will continue as part of WG7 activities (ARPA-SIMC)

5. WP 7.4 - Verification of ensemble forecasts Collaboration with WG5 and VERSUS for ensemble forecasting verification

6. WP 7.5 - Development of convection- permitting ensembles Product development and evaluation (MCH, A. Walser, M. Arpagaus) Studying model perturbations for COSMO at 2.8 km over Italy (ARPA- SIMC C. Marsigli, USAM/CNMCA L. Torrisi) Evaluate ECMWF LAM-EPS BC test data-sets for the convection- permitting scale (ARPA-SIMC, MCH)
