BORA  , an

Italian name for a violent cold northerly and north-easterly wind, common in the Adriatic, especially on the Istrian and Dalmatian coasts . There is always a northern tendency in the winds on the north Mediterranean shores in winter owing to the cold air of the mountains sliding down to the sea where the pressure is less . When, therefore, a cyclone is formed over the Mediterranean, the currents in its north-western area draw the air ,from the cold northern regions, and during the passage of the cyclone the bora prevails . The bora also occurs at Novorossiysk on the Black Sea . It is precisely similar in character to the mistral which prevails in Provence and along the French Mediterranean littoral .
