Sažetak
The article presents a very high-resolution dynamical adaptation of the wind field with the hydrostatic version of the ALADIN model used in the operational suite, including a sensitivity study of a recent case of bura and a MAP IOP 15 case study. Bura is a strong wind with severe gusts ; it occurs suddenly and affects traffic on the eastern Adriatic. It has a large spatial variability and depends on an upstream terrain configuration. The described approach makes it possible to predict the occurrence, strength and spatial variability of the wind field in the mountainous area of the eastern Adriatic coast. Although this area is often affected by severe wind events (bura), measured wind data do not provide adequate coverage and are usually not representative enough. Good performance of the operational wind prediction encouraged its use for estimating the expected extreme wind speeds on the route of a new highway. Two sensitivity tests were carried out to explore the impact of the neglected processes. It was found that the impact is negligible in the case of severe bura event.
