On the influence of resolution on wave modelled results in the Mediterranean Sea

We have explored the sensitivity of the wave modelled results in the Mediterranean Sea to the grid and integration time step resolutions. The results show that in areas with a complicated coastal shape an improved grid resolution provides often substantial local differences, mostly associate to the effect of, but not necessarily close to, the coasts. Some smaller differences are associated also to the accuracy of the numerical procedure. The use of different time steps did not provide appreciable differences. We have also explored how the quality of the wind fields in the Mediterranean Sea is going to improve with the shift of the resolution of the ECMWF meteorological model from T511 (40 km) to T799 (25 km).
