Sažetak
We describe the two-way coupling between the COSMO limited area meteorological and the WAM wave models. Following the approach first used at the European Centre for Medium-Range Weather Forecasts at the global scale, the coupling is achieved by passing from COSMO to WAM the air density and the 10 m height wind, while in the other direction the flowing info concerns the Charnock coefficient representative of the wave induced surface roughness. The coupling does not affect the original turbulence closure of the COSMO meteorological model. The different decomposition used in the two models, simple for COSMO, more complicated, but computer effective, in the case of WAM, implies special care in the interpolation, especially at the interface between land and sea. COSMO has been kept as the leading model. Still in the development stage, the coupled model system has been applied with 0.25 degree resolution for a two month period, Nov-Dec 2010. The area of interest is the Mediterranean Sea. The results, obtained without data assimilation, but simply driven by the boundary conditions, show the expected reduction of the wind speed and wave height in areas of active generation, together with a more limited deepening of the developing cyclones. The reduction is particularly evident in areas characterised by strong wind and short fetch, typically bora and mistral, where the air- sea interaction processes are extremely active.
