Such winds are sometimes also called fall winds. Anabatic winds can be useful for gliding and sailplanes.

Local Winds

Katabatic winds are usually cool.

Katabatic winds short definition. Almost a week into the challenge Sion Morgan checks his progress. Katabatic wind also called downslope wind or gravity wind wind that blows down a slope because of gravity. Copyright HarperCollins Publishers.

The surface cools a vertical column of the atmospherestarting at the slope surface and reaching perhaps 10100 m deep. It therefore begins to flow downhill. This flow known as a katabatic wind extends out a considerable distance from the Derwent River mouth typically 10 to 20 kilometres.

A microburst is a small concentrated downburst that produces an outward burst of strong winds at or near the surface. A cold flow of air travelling down an orographic slope eg. The nocturnal component of the along-slope wind systems.

You can either type in the word you are looking for in the box below or browse by letter. Katabatic wind Most widely used in mountain meteorology to denote a downslope flow driven by cooling at the slope surface during periods of light larger-scale winds. The air in contact with these highlands is thus also cooled and it becomes denser than the air at the same elevation but away from the slope.

Of a wind caused by local downward motion of cool air. The spelling catabatic winds is also used. Katabatic wind Noun A drainage wind fall wind.

Descending cold dense bodies of air are sometimes termed katabatic flows or katabatic winds at the ground level and ascending heated air constitutes the anabatic winds Such density differences cause lateral pressure gradients which produce horizontal motion with cold air moving over the ground into a warmer air mass. Katabatic Winds Katabatic winds are also occasionally referred to as gravity-driven winds a moniker that concisely explains their nature. Definition of katabatic.

Of or relating to the downward flow of cold dense air. Nouns denoting natural phenomena. Air becomes denser with decreasing temperature and thus succumbs to.

Katabatic synonyms katabatic pronunciation katabatic translation English dictionary definition of katabatic. Katabatic a polar katabatic wind adj. Wind air moving sometimes with considerable force from an area of high pressure to an area of low pressure.

American Heritage Dictionary of the English. Relating to or being a wind produced by the flow of cold dense air down a slope as of a mountain or glacier in an area subject to radiational cooling. Relating to wind currents that blow down a gradient especially down the slopes of a mountain or glacier.

A wind such as the bora or Böhmwind which moves high density air from a higher elevation down an incline due to the force of gravity. The opposite of an anabatic wind is a katabatic wind which blows down the slope of a mountain. When air comes in contact with the cool surface of a glacier or the upper regions of a mountain or slope the air cools becomes dense and blows downward.

Additionally katabatic winds blow at night and are caused by reversed temperature differences between the air column and the mountain slope. 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. Hypernyms katabatic wind is a kind of.

A wind caused by the downward motion of cold air. Katabatic Wind A wind that is created by air flowing downhill. Katabatic in British English.

Microbursts are small less than 4 km across and short-lived lasting only five to 10 minutes with maximum windspeeds sometimes exceeding 100 mph. Of winds blowing downhill through having become denser with cooling esp at night when heat is lost from the earths surface. It occurs at night when the highlands radiate heat and are cooled.

They form as cold air over snowy uplands spills downward into adjacent lowlands. Katabatic - definition of katabatic by The Free Dictionary.
