Sažetak
The paper presents the ability of forecasting severe bura events on the Adriatic coast using the ALADIN model operationally used at the Croatian Meteorological Service. Both versions currently in use, the LACE and the Croatian version, as well as the dynamical adaptation of the surface wind field from the latter are tested on a MAP IOP 15 case. The MAP IOP 15 took place between 5th and 10th November 1999. The strongest bura was recorded around 12 UTC on 7th November. Different versions of the same numerical model are used on different domains and resolutions. The output surface wind fields from the 8-km resolution Croatian domain are dynamically adapted to orography with a 2-km resolution, and both results are compared to the measured data. The latter method proved to be very useful for locations where the bura is the most severe, like the Maslenica bridge. The impact of a better representation of orography on the forecasted wind field in the mountainous parts of the coast is visible in the increased spatial variability of the field.
