Strategy of Meteo. Swiss Domain weather • 3 forecasting centers in Zurich, Geneva & Locarno covering different climatic and linguistic regions • Forecasts for the aviation in Zurich & Geneva • Common forecast matrix covering 10 days (since 2. 9. 08) • initialized with COSMO-7, COSMO-LEPS, IFS • one central guidance (view of the synoptic evolution) • local adaptations in the matrix made by regional centers • used to generate automatically most products (ongoing) • base to compute the global score MOVI • Products for official duty (including official warnings) as well as customer specific ones (commercial) • Model products derived directly to customers Plans of Meteo.

Main achievements last COSMO year • Introduction of the new multilayer soil model (9. 07) • Large success of project MAP D-PHASE • Operational period 6. 07 -11. 07 • Involvement of 26 end users • Preoperational coupling with 4 hydrological models • Platform still running (national platform in development) • COSMO-7 at 6. 6 km with Runge-Kutta & new μ-physic (11. 07) • Operationalisation of COSMO-2 (2. 08) • Start of deliveries in project CN Met (nuclear power plants) • Activation of Latent Heat Nudging (4. 08) • Replacement of Front-end used for pre- & post-processing as well as for R&D (operations: 1. 08, rest 6. 08) Plans of Meteo.

Planned main activities next COSMO year • Consolidation of the COSMO chain • Soil, snow (analysis), vertical levels (thin levels, SLEVE 2) • Nudging of more observations • Investigation of poor forecasts (esp. convection) • More comprehensive information on model performance • in close cooperation with forecasters • Extend the existing post-processing methods • Combined products COSMO-2, -7 and -LEPS • Use COSMO-ART for pollen forecasts (chemistry @ partner) • Development of an on-demand mode (project CN Met) • 6 h forecasts of COSMO-2 each hour (max twice/year) Plans of Meteo.

Contributions to COSMO next COSMO year • SPM function and coordination WG 4 • Priority projects • COLOBOC: PL, soil, snow (analysis), contribution to the external parameters, urban model • KENDA: „non-Gaussianity“, best member selection with conventional measurements (SIR-Filter) • UTCS: 1 -equation model: component testing & comparison • CONSENS: tuned calibration algorithm for COSMO-LEPS • VERSUS 2: requirements, install & test • Test of new COSMO versions • Possible contribution to code maintenance (post-processing) • Nudging of further observations: near surface parameters, ZTD, humidity profiles (GPS tomography) Plans of Meteo.
