Sažetak
The global model reanalysis, forecast or climate data needs to be downscaled to provide information for regional interpretation. This is especially true in complex terrain of Croatia, where weather conditions are governed by the effects of mountains and the Adriatic Sea and the atmosphere. One of the climatological particularities of the region is related to bora winds, severe downslope windstorms. Bora winds are especially frequent in winter and may reach hurricane 5 scale gusts, therefore being a major threat to population safety and coastal infrastructure. Dynamical downscaling of global reanalysis data was performed with the use of ALADIN model at the final grid spacing of 2 km during a 10-year period. Moment-based and spectral verification of wind speed, performed on a number of surface stations in different climate regions of Croatia, suggested that downscaling was successful. The highest modelled wind gust reached ~ 68 m/s near the lee of the southern Velebit Mountain, which is in an excellent agreement with the intensity and location of the highest observed maximal gusts. Results suggest ALADIN wind and wind gust climatology is appropriate for using in studies of air-sea interaction and hydrological cycle over the Adriatic where the observed data is scarce, as well as for a range of other purposes such as infrastructure planning and offshore wind resource potential estimates.
