foehn"(Or föhn.) A warm, dry, downslope wind descending the lee side of the Alps as a result of synoptic-scale, cross-barrier flow over the mountain range.
Foehn Winds: Winds descending downslope from mountains which are characteristically warm and dry due to adiabatic compression.
Foehn
(Similar in pronunciation to 'fern'.) Wind warmed and dried by descent, in general on the lee* side of a mountain. See the explanation and animation in Fig.1 below.
* The side away from the direction the wind is blowing from.
FOEHN
A warm dry wind on the lee side of a mountain range, whose temperature is increased as the wind descends down the slope. It is created when air flows downhill from a high elevation, raising the temperature by adiabatic compression.
Foehn effect
The warming effect of air flowing down the leeward side of a mountain range. The heating and drying of the air is due to adiabatic compression of the air as it flows down the slope.
Foehn Wind- European term for Chinook Wind; or warm, downslope wind.
Flood- a condition that occurs when water overflows the natural or artificial confines of a stream or river; the water also may accumulate by drainage over low-lying areas.
Foehn See Chinook.
Fog A cloud with its base at the earth's surface. It reduces visibility to below 1 km.
Forced convection On a small scale, a form of mechanical stirring taking place when twisting eddies of air are able to mix.
FOEHN - A warm dry wind on the lee side of a mountain range. The heating and drying are due to adiabatic compression as the wind descend downslope.
Foehn Pause
A temporary cessation of the foehn at the ground due to the formation or intrusion of a cold air layer which lifts the foehn off the ground.

Foehn - A warm, dry wind on the ice side of a mountain range that owes its relatively high temperature largely to adiabatic heating during descent down mountain slopes.
Fog - A cloud with its base at or very near Earth's surface.
foehn—A warm, dry downslope wind; the warmness and dryness being due to adiabatic compression upon descent; characteristic of mountainous regions. See adiabatic process, Chinook, Santa Ana.
FOEHN - A drier and warmer downslope wind on the lee side of a mountain range. Marked by air subsidence.
FOEHN GAP - Absence of clouds on the lee side of a mountain range caused by sinking air (subsidence).
Classified as katabatic, it occurs most often during the winter and it is an example of a foehn wind. SARGASSO SEA An area of the North Atlantic Ocean between Bermuda and the Azores.
In the Alps, the wind is called a Foehn.cirrocumulusA cirriform cloud characterized by thin, white patches, each of which is composed of very small granules or ripples. These clouds are of high altitude (20,000-40,000 feet or 6000-12,000 meters).
8 Wind: Chinook: Called (Foehn) downslope speeds of 100 mph. 9 Wind: Cold air move towards warm air. 10 Wind: Eddies. CAT: Clear Air Turbulence. 11 Wind: Fallout form atomic explosions. 12 Wind: Fire Weather Forecast. 13 Wind: Florida.
If warm, it is a foehn. If cold, it may be a fall wind or a gravity wind. Katathermometer A type of cooling-power anemometer based upon the principle that the time constant of a thermometer is a function of its ventilation.
CHINOOK A type of foehn wind. Refers to the warm downslope wind in the Rocky Mountains that may occur after an intense cold spell when the temperature could rise by 20°F to 40°F in a matter of minutes.
Chinook - Warm dry foehn, or Föhn wind downwind from the Rocky Mountains.
Climate - multi-year average temperature, precipitation and other weather conditions for a given region.

Chinook - Also called Foehn Winds, chinooks are warm, dry winds that occur in the lee of high mountain ranges.
Santa Ana Wind A strong, hot, dry foehn-like wind that blows from the north, northeast, or east into southern California.
Local names for Down slope winds or "foehn winds" in the western United States are Chinook Winds, East Winds, North Winds and Mono Winds. Usually associated with little or no clouds.
Katabatic wind Any wind blowing down an incline; the opposite to anabatic wind. If the wind is warm, it is called a foehn; if cold, it may be a fall wind (bora), or a gravity wind (mountain wind).
The local name given a foehn wind in southern California.
Saturation vapor pressure(6) ...
Some regional winds such as the foehn (German and Austrian Alps), Chinook (Rocky Mountains), and Santa Ana (Southern California) are dry, warm katabatic winds.
Chinook wind A warm, dry wind on the eastern side of the Rocky Mountains. In the Alps, this wind is called a foehn.
These may be further subdivided into barrier jets, gap winds, downslope windstorms, and include such local phenomena as the tehuantepecer, Santa Ana, foehn, mistral, and bora.
Canyon WindA foehn wind that is channeled through a canyon as it descends the lee side of a mountain barrier.
occur to the leeward side of mountain ranges around the world are known by many names. In Canada and the northern United States, they are referred to as Chinooks. In the southern states, they are known as Santa Ana and in parts of Europe, foehn winds.
conductivity, or compression, and the cycle repeats itself. (The heating through compression of descending air is what is responsible for such welcome winter phenomena as what is known in Western North America as a chinook or in the Alps as a foehn.) ...
