Sažetak
The subject of this study is a cyclonic vortex genesis in the wind field over the Adriatic Sea. The vortex is an unbalanced - ageostrophic circulation system in which the center of vortex does not coincide with the center of low pressure. It is not formed by the lee-side effects as Alpine lee cyclogenesis, but the orographic influence appears through the special local winds - bora in the northern and jugo in the southern Adriatic. Both winds are relatively shallow and modified by the Dinaric Alps. Bora flow originates in the eastern side of Alps indicating an internal hydraulic mechanism across the mountain barrier. The jugo wind is associated with a cyclonic circulation in the Genoa bay entering the Adriatic area adds a southerly wind, but changing the direction to SE when approaching the coastal mountain barrier of Dinaric Alps. Mesoscale wind analysis emphasises a current through the valley in northern Italy (not the western side of Alps) toward the Genoa bay. An example of such a vortex generation is presented for the case of October 1999 during the MAP IOP 5.
