A wind that flows down slopes, usually at night. The air at the top of the slope is cooled a greater amount by radiation than the air lower down, becomes heavier, and flows down the slope under the influence of gravity. The opposite of katabatic is anabatic, applied to a wind blowing up a slope, if it is caused by the convection of heated air.
Any wind blowing downslope. It is usually cold.
a wind that blows down a slope which is strongly cooled after sunset. Given the right topography and surface composition, surprisingly high speeds can be achieved in otherwise light-wind situations.
A phenomenon that originates with a layer of cold air forming near the ground on a night with clear skies and a low pressure gradient. If the ground is sloping, the air close to the ground is colder than air at the same level but at some horizontal distance. The result is downslope gravitational flow of the colder, denser air beneath the warmer, lighter air. This occurs on the largest scale as the outflowing winds from Greenland and Antarctica. Contrast with anabatic wind.
Any wind blowing down an incline, often due to cold air drainage.
Local winds a result of cold, dense air flowing downhill.
Any wind blowing down the slope of a mountain.
Any wind blowing down an incline; the opposite of anabatic wind.
a wind caused by the downward motion of cold air
a wind blowing down a gradient caused by buoyancy forces - ie the air is cool
A down slope wind due to density variations caused by cooling. Also called a drainage wind.
Down slope gravitational flow of the colder, denser air beneath the warmer , lighter air results and comprises the katabatic wind. It is also known as the drainage wind or mountain wind.
Air that flows under the influence of gravity from higher toward lower elevations. A air is initially very cold thus it has a high density and is thus negatively buoyant.
Any wind blowing down an incline. If warm, it is a foehn. If cold, it may be a fall wind or a gravity wind.
Downslope gravitational flow of colder, denser air beneath the warmer, lighter air. Also known as 'drainage wind' or 'mountain breeze'. Strength can vary from gentle to extremely violent winds.
The flow of cold dense air downslope under the influence of gravity; the direction of flow is controlled largely by topography.
A wind that is created by air flowing downhill. When this air is warm, it may be called a foehn wind, and regionally it may be known as a Chinook or Santa Ana. When this air is cold or cool, it is called a drainage wind, and regionally it may be known as a mountain breeze or glacier wind. The opposite of an anabatic wind.
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. Such winds, particularly when they occur over a wide area, are sometimes called fall winds.
