Buildings in several towns and villages in Slovenia and the Province of Trieste (Italy) have stones on their roofs to prevent the tiles from being blown off. A set of nested surveys occupied after a strong Bora event captured the counter-rotating gyres and upwind extension of the Po River plume (Fig. flowing westward to follow the bathymetry (forming the Mid-Adriatic Filament (MAF)), with the remainder continuing north along the Croatian coast. The winds blow into different directions. Bora usually emerges due to the difference between the temperature of the air above the land and the sea surface temperature. The edges of these clouds are sharp while their lower surfaces are horizontal. Typical meteorological condition producing a Bora That said, a skipper in the Adriatic should check isobaric weather charts and look out for a rapid moving low-pressure system passing Central Europe situated somewhere near the Black Sea. Shorter Sunny Season. Bora - Adriatic Sea develops in the winter when cold polar air builds over the Balkans and flows katabatically through the valleys of the Dinaric Alps and into the Adriatic Sea. Near the towns of Senj, Stara Novalja, Karlobag and the southern portal of the Sveti Rok Tunnel in Croatia, it can reach speeds of up to 220 kilometers per hour. A. Bajić, B. Peroš, V. Vučetić, Z.

The sirocco is a SE wind, which brings warm, humid air to the Adriatic area. In the summer the bora blows as a local wind and lasts only a few days. It is a dry and cold wind blowing from the north-eastern quadrant. The period of bora is usually followed by a long period of pleasant weather. [13], The wind is also an integral feature of Slovenia's Vipava Valley and, to a lesser extent, the Karst Plateau (known as Carso in Italian), an area of limestone heights over the Gulf of Trieste stretching towards the Istrian peninsula. It is accompanied by heavy clouds and rain. As a result, we have a landscape of unique beauty that offers a relatively mild climate, despite having a typical mountain terrain. It blows hardest when a polar high-pressure area sits over the snow-covered mountains of the interior plateau behind the Dinaric coastal mountain range and a calm low-pressure area lies further south over the warmer Adriatic. Due to being a dry wind it reduces the relative humidity of the air and therefore increases visibility. The jugo is a warm, humid east-southeast wind.

The winds blowing in the Velebit Canal rush down the extremely steep slopes from the peaks which reach the height of 1000 m or more. In the winter the temperature ranges from 12 to 14 °C (54 to 57 °F). In the winter it may continue for up to two weeks. BORA is a numerical weather and marine forecast service for the Adriatic Sea. Bora - Adriatic Sea may be associated with stormy weather, with winds reaching 100 knots or more. The cyclonic bora is often accompanied by a sudden barometric pressure fall and the appearance of the clouds on the southwestern horizon. Short, high waves with white crests are its characteristics, making the navigation difficult. [2005] showed that limited‐area meteo-rological models (with scales of 4 and 7 km) can represent the distinct jets that characterize the Bora response, while Chains and ropes are occasionally stretched along the sidewalks in downtown Trieste, Italy, to facilitate pedestrian traffic — gusts in the city are usually above 120 km/h reaching to maxima of near 200 km/h. 3) anticipated from numerical results Orlic et al., 1994.
