Use of Dynamical Adaptation in Research Impact Studies

Successful operational forecasting of strength, occurrence and spatial distribution of strong winds (bura) that frequently disturb traffic along the eastern Adriatic coast encouraged further usage of the dynamical adaptation method in impact studies. These events are so common that high-resolution operational wind speed forecast provided by the dynamical adaptation became the irreplaceable part of the ALADIN-Croatia operational suite. Roads and bridges in the Dinaric Alps region get closed due to very strong winds with gusts of more than 40 m/s. Results from an impact study of severe wind on the Maslenica Bridge and planned highway in the Dinaric Alps region will be shown. The study is based on the dynamical adaptation of wind field to 2-km resolution topography, output from the 8km resolution ALADIN model. Modelled wind filed will be compared to the measured data. The study has shown that wind is expected to be stronger along the road than it is on the Maslenica Bridge. Forecast of wind speed has already proven to be very good for Maslenica Bridge in strong bura situations on a study on MAP IOP 15 case.
