A Foehn, or Föhn (UK: / f ɜː n /, US: / f eɪ n / fayn, [2] [3] US also / f ʌ n, f ɜːr n / fu(r)n [4] [5]), is a type of dry, relatively warm downslope wind in the lee of a mountain range. It is a rain shadow wind that results from the subsequent adiabatic warming of air that has dropped most of its moisture on windward slopes (see ...
Foehn winds usually occur when the westerly wind belt moves northwards. [7]The foehn effect on the coastal plains of southeastern Australia is mostly linked with the passage of a deep low pressure system or westerly cold fronts across the Great Australian Bight and southeastern Australia that cause strong winds to reorient virtually perpendicular to some parts of the Great Dividing Range ...
A difference in air pressure causes an air displacement and generates the wind. The Coriolis force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. [1] It is also referred as the geostrophic wind. [2]
Euroclydon (a cyclonic tempestuous northeast wind in the Mediterranean) Föhn or foehn (a warm, dry, southerly wind off the northern side of the Alps and North Italy. The name gave rise to the fén-fēng (焚風 'burning wind') of Taiwan). Gregale (northeasterly from Greece) Halny (in northern Carpathians) Helm (north-easterly wind in Cumbria ...
On the leeward side of the mountain, the air flowing downward is known as a foehn wind. Because some of the moisture that has condensed on the top of the mountain has precipitated, the foehn (or föhn) is drier, and the lower moisture content causes the descending air mass to warm up more than it had cooled down during ascent.
In drier climates, “spotting” can occur, Cobb said, where the wind can pick up embers, causing them to fly and ignite dry grass. “A spot fire can jump a quarter mile from the main embers ...
Diagram showing the Foehn effect creating the Zonda. The Zonda is a dry wind (often carrying dust) which comes from the polar maritime air, warmed by descent from the crest, which is approximately 6,000 m (20,000 ft) above sea level. It may exceed a velocity of 240 km/h (150 mph).
There are four weeks left before the conference championship games, meaning we are inching closer to finding out who will be in the first 12-team College Football Playoff.
