BORA

bora, an italian name for a violent cold northerly and northeasterly 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.
