WIND ROSES FOR SEVERAL ONSHORE-OFFSHORE PROFILES AT THE EASTERN ADRIATIC COAST

Wind roses for three onshore-offshore profiles at the Eastern Adriatic coast (Croatia) are considered. The profiles are following: 1) the Northeast Senj – Rab – Mali Lošinj, 2) middle Adriatic profile Split Marjan – Hvar – Komiža and 3) the Southern Adriatic profile Dubrovnik – Lastovo – Palagruža. Time series of instantaneous (at 07 h, 14 h and 21 h of local time) wind data for period 1981– 1998 have been used. Wind roses strongly depends on spatial wind pattern i.e. wind type. Thus for the sea breeze conditions the winds form SW quadrant prevails for most considered weather stations, while Ethesians (from NW quadrant) wind prevails at Palagruža and Lastovo islands. During jugo (or sirocco), wind directions are concentrated on SE quadrant. An exception is Senj station where canalising jugo wind is not stressed. During bura (or bora) conditions, concentration of the wind directions is located into NE quadrant. Only one direction is very dominant at coastal locations
