Wind Forecast Verification during Various Bora Events at Dubrovnik Airport

Several airports are situated in the lee side of the Dinaric Alps where the bora flow is well-known. Bora reduces air traffic operations especially if its direction is perpendicular to the runway direction as is the case at Dubrovnik airport. Terminal Aerodrome Forecast (TAF) is important in decision making during the flight planning process. TAF wind forecasts are verified compared to observed METAR reports in the period 2009-2014. Climatology shows that the frequency of hours with NE wind greater than 7.5m/s (15KT) is 10-15% in winter time. Bora is dominantly driven by large scale dynamics, hence it is forecasted well. The diagnostic verification results are shown according to lead time, issue time, months. Additionally, profiles from ALADIN model are used to determine the type of flow (shallow, deep or nocturnal downslope flow).
