Sažetak
Bora wind field is characterised by strong vorticity and divergence. Several numerical experiments, in which oceanographic model was forced with northeasterly winds having climatological alongshore variability, were performed in order to study the influence of spatial variability in the bora wind field on the surface currents in the northern Adriatic. Numerical model results showed that during bora episodes with lower speeds and fast offshore decay surface currents along transect Rovinj – Po River are dominantly in the downwind direction. On the other hand, during bora episodes with strong intensity and slow offshore decay cyclonic gyre due to the pronounced bora alongshore variability is formed in the northernmost part of the Adriatic Sea and the studied transect is influenced by the counter currents. Moreover, bora having high speed and short offshore range produces the same effect in the eastern part of the Rovinj – Po River transect as low-speed bora characterised by slow offshore decay. Eulerian current measurements performed in the northern Adriatic during bora episodes characterised by different synoptic conditions supported the numerical model findings. Surface currents during the bora episode of 8– 11 February 1984 were directed downwind, whereas during the episode of 12– 19 February 1984 they were directed upwind. The first episode was characterised by deep bora layer with cyclonic activity over the western Mediterranean and Genoa Bay, whereas the second one was accompanied by temperature inversion and southwesterly tropospheric wind above shallow bora layer. According to hydraulic theory developed by Smith (1985), observed descend of isentropes during the second bora episode led to the stronger acceleration in the bora layer and its larger offshore extent. Different offshore bora decays during studied events were confirmed by comparison of the wind data originating from the meteorological stations positioned on the opposite Adriatic coasts.
