We study an early stage of a bora event over the northern Adriatic that occurred on 7 November 1999 during the Mesoscale Alpine Program (MAP) Intensive Observation Period 15. We use the aircraft data measured along the lee side of the Dinaric Alps over the Adriatic by the NCAR Electra aircraft flying two vertically separated flight legs (lower at ~ 370 m, higher at ~ 680 m). Measurements from six dropsondes released from 4200 m along the legs are used as well.
Using these data, main features of turbulence along the northern Adriatic are derived (spatial distribution of TKE and its dissipation rate). The question of the origin of this turbulence naturally arises; is it a local phenomenon or maybe advection plays a significant role? Since the answer is difficult to obtain only from the measurements, we have simulated this event using WRF-ARW model with five different PBL parameterization schemes. It seems that one of them agrees particularly well in comparison with the measurements.
