The Adriatic Sea wave response to severe bura wind

Bura is a strong wind with severe gusts ; it occurs suddenly and affects safety of life at sea. It has a large spatial variability and depends on an upstream terrain configuration. The quality of surface winds derived from meteorological models is the key issue (and input) in wave modelling. In this study we are addressing question of storm bura wind and effect on wave field response. Increase in the predicted wind field resolution from 8 to 2 km using Aladin model dynamical adaptation enables high resolution wave forecast as well. There is little information about detailed structure of the wave field (significant height and direction) in the Adriatic Sea produced by severe bura wind. Results for wave response of the Adriatic Sea for 13-18 of November 2004 storm are presented and discussed in detail, as well as differences due to forcing of the wave model with 8 km and 2 km ALADIN wind fields. Comparison of modelled wave response is made with in situ ADCP wave measurements.
