Sažetak
Winds through the Vratnik Pass, a mountain gap in the Dinaric Alps, Croatia, are polarized along the gap axis that extends in the northeast-southwest direction. Although stronger northeasterly wind at the Vratnik Pass is frequently related to the Adriatic bora wind, especially at the downstream town of Senj, there are many cases when wind at Senj is directionally decoupled from wind at the Vratnik Pass. A cluster analysis reveals that this decoupling is sometimes related to lower wind speeds or shallow southeasterly sirocco wind along the Adriatic, but in many cases the bora blows over a wider region, while only Senj has different wind direction. Several mechanisms can be responsible for the latter phenomenon, including the formation of a lee wave rotor. A numerical model simulation corroborates the decoupling caused by a rotor for a single case. The prevalence of northeasterly winds at the Vratnik Pass during southeasterly sirocco episodes is another result that challenges the current understanding. It is shown that at least in one of the episodes, this phenomenon is related to a secondary mesoscale low-pressure center in the eastern lee of the Apennines that forms as a subsystem of a broader Genoa cyclone. Less frequent southwesterly winds through the gap are predominantly related to the thermal sea-breeze and anabatic circulations that are sometimes superimposed on the geostrophic wind.
