Our wind "Bora" and its origin by paoseo
There is peculiarity of Trieste that many people don't love...but I do! I'm speaking about our wind, "Bora". February is the peak month for bora but strong winds associated with the bora can also occur in any month. The other strong bora episodes usually end by April, but milder boras can occur in any month of the year.
The presence of The wind "Bora" , that is a dry, very cold continental wind , on Trieste depends on the geographical shaping of Trieste. The town lies at the extremity of a quite relatively warm sea and a wide and very cold hinterland with an open pass on the gulf of the city. This situation between the two zones, sea and hinterland,causes the possibility of the forming of strong differences of temperature and atmospheric pressure with the result of frequent and intense downflows of air masses from the hinterland towards the sea.
If this difference of pressure is exalted by the transit of a depression (cyclone) on the Adriatic sea, or by the creation of a high pressure zone (anticyclone) on the central- eastern Europe, or by the simultaneously presence of a depression on the sea and a high pressure on the continent, so the descending air flow achieves high speeds and characteristics of violence.
The wind can be ?Chiara? (light) if the sky is clear or ?Scura? (dark): if there are clouds created by the wind "Scirocco".
The bora announces itself with long and threatening hisses called refoli. In the most severe winters, people from Trieste say:
Tre giorni la nassi,Three days to be born
Tre giorni la cressi,Three days to grow,
Tre giorni la crepa , Three days to die
It's a strange situation when wind pushes you..in that case NEVER run...it will make you falling !!
