Bura – the strongest wind in Croatia


Since it is pretty windy today in Split, Croatia, you should know something more about Bura – nothern strong and cool wind characteristic for Dalmatian coast.

The changeable Bura can often be felt all over Dalmatia, Istra, Trieste, and the rest of the Adriatic east coast. It blows in gusts. The Bura is most common during the winter.
It starts 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. As the air grows even colder and thus denser at night, the Bura increases. Its initial temperature is so low that even with the warming occasioned by its descent it reaches the lowlands as a cold wind. The wind takes two different traditional names depending on associated meteorological conditions: the “light bora” (Italian: Bora chiara) is Bura in the presence of clear skies, whereas clouds gathering on the hilltops and moving towards the seaside with rain or snow characterize the “dark bura” (Bora scura).

The area where some of the strongest bora winds occur is the Velebit mountain range in Croatia. This seaside mountain chain, spanning 145 kilometers, represents a huge weather and climatic divide between the sharp continental climate of the interior, characterized by significant day/night temperature differences throughout the year, and the Adriatic coast, with a Mediterranean climate. Bura occurs because these two divided masses tend to equalize. Sailing can be extremely dangerous for an unexperienced navigator in the Velebit channel because the wind can start suddenly on a clear and calm day and result in major problems, frequently also affecting road traffic. 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.
On December 21, 1998 the speed of a gust on the Maslenica Bridge (north of Zadar) was measured at a record speed of 248 kilometres per hour.
During December 22 to 25, 2003 on Kralja Tomislava highway near Sveti Rok Tunnel new record was measured at speed of 304 kilometers per hour.Source: Wikipedia
