	Katabatic wind - Wikipedia, the free encyclopedia
		A katabatic wind, from the Greek word katabatikos meaning "going downhill", is a wind that blows down a topographic incline such as a hill, mountain, or glacier.
		A distinction is drawn between winds that are warmer than their surroundings (generally called Föhn or regionally, Chinook, Santa Ana, Bergwind or Diablo) and those that are cooler (for instance the Mistral in the Mediterranean, the Bura (or Bora) in the Adriatic or the Oroshi in Japan).
		Cold katabatic winds are frequently found in the early hours of the night when the solar heating has ceased and the ground cools by emitting infrared radiation.

		Wind is the quasi-horizontal movement of air (as opposed to an air current) caused by a horizontal pressure gradient force.
		Winds can be classified either by their scale, the kinds of forces which cause them (according to the atmospheric equations of motion), or the geographic regions in which they exist.
		The opposite of a katabatic wind is an anabatic wind, or an upward-moving wind.

		Katabatic is a word derived from the Greek Katabasis which means "an army marching through a country down toward the coast".
		Such winds are phenomena that originate with a layer of cold air forming near the ground on a night with clear skies and a low pressure gradient.
		The direction of the wind from either bora is approximately 060° in the entrance channel (30° off the port bow of an incoming vessel) and in Basin 3, the worst affected area of the port.

	Wind as a Factor in Arctic Weather and Climate
		Mountain and valley winds are part of the localized air circulation that develops along mountain slopes heated by solar radiation after winter snows have melted.
		In some places katabatic winds are channeled by mountain valleys, and the wind accelerates to potentially destructive speeds.
		For example, a wind out of the west is reported as a west wind, or wind direction 270 degrees.

	katabatic (Site not responding. Last check: 2007-09-05)
		Katabatic winds exist in many parts of the World and are winds that flow from the high elevations of mountains, plateaus, and hills down their slopes to the valleys or planes below.
		Katabatic winds are mostly synoptically triggered or they are activated by large scale weather features such as a high pressure system over the high elevations.
		Katabatic winds that are cold are heavily high density air related.

	Histoire Antar/FR/Introduction
		Because they belong to a category of winds called katabatic winds (from the Greek 'kata', meaning downwards); these winds are observed at every latitude of the globe as soon as the course of cooled air meets a significant slope, but nowhere are they as strong as they are in Antarctica.
		Under the action of the katabatic force of gravity, the movement of the air intensifies until it reaches its equalised velocity where the acceleration due to gravity is compensated by the air rubbing on the ground and the layers of air higher up.
		The scientists also theorise that katabatic winds could cause the appearance of breaks in the sea ice around the coast: in reaching such speeds and discharging with force on to the ice floes, the winds could push the ice away and thus enable some stretches of coastal water to remain ice-free.

	Southern Hemisphere Winds
		Katabatic winds normally form in the evening, the result of re-radiative cooling of upper slopes lowering the temperature of air in contact with it and the colder, denser air sinking rapidly down-slope.
		Katabatic winds are density or gravity currents and can also occur in the tropics, for example the Atherton tablelands in northern Queensland form a plateau adjacent to the tropical coast.
		In lighter winds the wind shadow of still water at the upwind edge of a small lake or dam is usually apparent.

		The winds from 90° and 150° constitute the main local circulation and have, most of the time, the characteristics of a katabatic flow while the winds blowing from 180°, arising from the surface temperature difference between the sea and the land, are land breezes.
		As the system had to work in the presence of strong winds, in severe weather and temperature conditions, an important point was the choice of a suitable orientation for the antennas in order to minimise the noise due to the presence of strong katabatic winds.
		A typical VNL katabatic wind profile is given as an example in Figure 11a for August 6, 1993 between 10:00 to 11:00 L.T. In Figure 12 the facsimile representation is shown for the same period.

		In the present paper, the katabatic winds are studied by means of numerical simulations using a mesoscale model as described in Heinemann (1997).
		This daily cycle of the katabatic wind system near the surface is reflected by surface station data in the area of southern Greenland, which were measured during the experiment KABEG in April/May 1997 (Heinemann, 1998).
		The daily course of the horizontal wind vector is shown in Fig.2 for a period with weak synoptic forcing for three stations on the ice sheet.

		(By contrast, an anabatic wind is warm and moves up a valley in the early morning.) When the sky is clear, heat escapes rapidly from ground surfaces, and the air above the ground becomes chilled.
		Cold air blown by a katabatic wind may collect in a depression or valley bottom to create a frost hollow.
		Katabatic winds are most likely to occur in the late spring and autumn because of the greater daily temperature differences.

		The wind is responsible for displacing the loose snow and firn to create whiteout conditions and for creating severe wind-chill conditions.
		The katabatic winds on the continent exist due to the airflow from the high pressure, cold, elevated plains down slope to the relatively warmer lower elevations with less pressure.
		The winds are associated with the surface cooling of the slope.

		The regions for the investigation of channelling effects of the katabatic wind were near Ilulissat (West Greenland) and southwest of Ang magssalik (East Greenland), where pronounced valley structures with steep topographic gradients are present.
		In all katabatic flights and from the measurements of the surface stations it was found that the katabatic wind system was well developed at that time.
		As a general result of the katabatic wind flights an acceleration of the wind close to the ice edge was found in the lower layers, which leads to a sharper wind maximum closer to the ice edge.

	The Environmental Literacy Council - The Santa Ana: Katabatic Winds
		While the prevailing winds in California come from the west from the cool Pacific ocean, the Santa Ana, named after the city of Santa Ana near Los Angeles, comes from the high, dry desert plateaus of the mountain ranges east of Los Angeles and San Diego.
		Winds pass over the top of mountains, but, like the eddies that swirl near rocks on a rocky shoreline, some air breaks away from the main wind stream, where it gathers and cools.
		In the case of the Santa Ana wind, these conditions are usually provided by high pressure in the northern Rocky Mountains of the U.S. The clockwise air circulation of this high pressure system forces the winds downwards from the high plateau.

	Weather \| Convection \| Sea Breeze \| Katabatic Wind
		Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high pressure region to the low pressure region.
		This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the northern hemisphere, and left in the southern hemisphere.
		Wind caused by differences in temperature is known as convection or advection.

		The Antarctic is unique in that the elevated plateau of the west Antarctic produces extreme katabatic flows which dominate the circulation of the continent and nearby Southern Ocean.
		Because of the atmospheric jet structure in the along-shore direction, the corresponding curl produced downwelling in the ocean shoreward of approximately 100 km and upwelling from 100-300 km offshore.
		The strong curl in the wind stress produced by the transition from the midlatitude westerlies to the polar easterlies is an important factor in the forcing of the Southern Ocean.
