What is the term for a cold and very dry wind, occurring in the region of the Adriatic Sea?

The Bora is a cold and very dry and often gusty katabatic wind (fall-wind) from the north-east. Bora winds can occur anytime during the year. However, the peak frequency occurs in November - March. The term Bora derives from the Greek term 'Boreas': the north. In other areas it is used as a generic term for cold squalls moving downhill from uplands.

The Bora is most commonly blowing down from the mountains on the eastern side of the Adriatic Sea where it flows mainly from the northeast through gaps in the Dinaric Alps. On occasion, the Bora can be very localized, extending only a few miles offshore. At other times, the Bora will dominate the entire Adriatic Sea and, when the area of steep pressure gradiant is large enough, the Bora can extend as far south as Malta. The strongest winds occur along the eastern shores of the Adriatic Sea from Trieste to the Albanian border.

The Bora wind is associated with two primary weather patterns; In both cases, the European side has a higher air pressure than the Mediterranean side.

The black Bora is generally a less gusty wind and may result in a substantial amount of rain or snow in the region, accompanied by low clouds, reducing visibility.

The white Bora is typically dry and very gusty as a result of its katabatic nature. Almost cloudless skies, cold weather, and good visibility on the lee side of the coastal mountains, and a thick cloud on the crest of the mountains are its characteristics.
