Examples of true katabatic winds include the bora in the Adriatic, the Bohemian Wind or Böhmwind in the Ore Mountains, the Santa Ana in southern California, the piteraq winds of Greenland, and the oroshi in Japan.
What is the Adriatic wind called?
Ostro
Ostro (Croatian: Oštro) is a southerly wind in the Mediterranean Sea, especially the Adriatic. Its name is Italian, derived from the Latin name Auster, which also meant a southerly wind. It is a warm and humid wind that often carries rain, but it is also sometimes identified with libeccio and sirocco.
What is the cold wind of Adriatic Sea coast?
Bura
Bura – a cold Adriatic wind As a cold wind, Bura vertically inclines the slopes of the coastal mountains and moving towards the sea. It produces dust clouds that decrease visibility. Bura is declared by a “cap” of clouds that appear and therefore could be very severe and unexpected.
What is the local nomenclature of katabatic Anabatic wind in Adriatic?
The ‘Bora’ is a katabatic wind occurring in the Adriatic Sea, Black Sea, Southeastern Europe and Turkey. ‘Bora’ winds arises most often in the winter when high density cold air flows towards the sea.
What role do katabatic winds play?
katabatic wind, also called downslope wind, or gravity wind, wind that blows down a slope because of gravity. It occurs at night, when the highlands radiate heat and are cooled. This process is most pronounced in calm air because winds mix the air and prevent cold pockets from forming.
What are katabatic and Anabatic winds?
Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column. Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.
How does katabatic winds develop?
Katabatic winds occur when air is cooled from below over sloping terrain. Such cooling causes a shallow blanket of air adjacent to the surface to become colder and therefore heavier than the atmosphere above, thus forming a thermally distinct layer that exchanges little energy with the overlying air.
What is tramontane wind?
The tramontane [tʁa. mɔ̃. tan] in France is a strong, dry cold wind from the north (on the Mediterranean) or from the northwest (in lower Languedoc, Roussillon, Catalonia and the Balearic Islands). In 1636 the French expression “perdre la tramontane” meant “to be disorientated.”
What is cold wind called?
Mistral A cold, dry wind blowing from the north over the northwest coast of the Mediterranean Sea, particularly over the Gulf of Lions. Also called CIERZO. See also FALL WIND.
What are Anabatic and katabatic winds?
What are the characteristics of katabatic winds?
katabatic wind, also called downslope wind, or gravity wind, wind that blows down a slope because of gravity. It occurs at night, when the highlands radiate heat and are cooled.
What is the meaning of katabatic wind?
A katabatic wind (named from the Greek word κατάβασις katabasis, meaning “descending”) is a drainage wind, a wind that carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds; the spelling catabatic winds is also used.
Are all downslope winds katabatic?
Not all downslope winds are katabatic. For instance, winds such as the föhn and chinook are rain shadow winds where air driven upslope on the windward side of a mountain range drops its moisture and descends leeward drier and warmer.
Why are there so many bora winds in the Adriatic Sea?
Because the region separates the lower Adriatic coast from the Julian Alps range, extreme bora winds often occur there. They have influenced the region’s traditional lifestyle and architecture. Towns on the coast, where the bora frequently occurs, are built densely with narrow streets in part because of the wind.
What is the wind speed in Croatia?
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 21 December 1998 the speed of a gust on the Maslenica Bridge (north of Zadar) was measured at a record speed of 248 kilometres per hour, and wind shields were installed.
