over the Adriatic Sea low air pressure prevails. It is generally distinguished between the black bora (cyclonic bora) and the white bora (anticyclonic bora) It occurs when cold air reaches the northern Balkan regions, especially the area of the side of the Dinaric Mountains facing away from the sea, and here the air pressure rises, while in southern regions, i.e. Bora or Bura – probably the most feared wind in CroatiaĪmong the most feared wind in the Adriatic, especially in the months of October to April, is the bora. Not only sailors know the problem from the Velebit mountains near Senj, where the bora presses strongly on the sea again and again. In this context, mountains and valleys provide natural obstacles, but if they reach the sea, they also influence the wind strength in a similar way to a funnel. The greater the difference between areas with low air pressures and high air pressures, the stronger the respective wind. Winds such as maestral, jugo, nevera / neverin or bora occur whenever the air tries to escape from an area of higher air pressure to an area of lower air pressure, or, as the fundamentals of thermodynamics define it quite simply, to ensure an even distribution of air particles in the given space, but also in the area of thunderstorm cells.
Winds blow from high to low pressure areas The third wind typical for the region, the maestral, is somewhat more harmless. For this reason, skippers should familiarize themselves with the peculiarities of the particular area in which they are sailing, because anyone who is not familiar with the harbingers and warning signs of Jugo and Bora, as well as the regional hotspots of these weather events, can literally be shipwrecked. The subject of wind, or the Latin term “Ventus”, exerts a not inconsiderable influence on seafaring in the areas of Croatia, Slovenia and northern Italy, depending on the strength measured in Beaufort.
