WebbPart of the International Union of Theoretical and Applied Mechanics book series (IUTAM) Abstract Waves in a stratified flow are a prominent and dramatic feature in the lee of a mountain range that stands athwart the prevailing winds, such as the Sierra Nevada in California or the Southern Alps in New Zealand. WebbDenudation is the geological processes in which moving water, ice, wind, and waves erode the Earth's surface, leading to a reduction in elevation and in relief of landforms and landscapes. Although the terms erosion and …

In meteorology, lee waves are atmospheric stationary waves. The most common form is mountain waves, which are atmospheric internal gravity waves. These were discovered in 1933 by two German glider pilots, Hans Deutschmann and Wolf Hirth, above the Krkonoše. They are periodic changes of atmospheric pressure, temperature and orthometric height in a current of air caused by vertical … WebbThis paper presents a three-dimensional small-perturbation approach to the problem of waves produced in a statically stable stratified air stream flowing over a mountain.

WebbFigure 5. Mountain waves. Sometimes, these waves propagate long distances in “lee wave trains”, so the effects may also be felt a great distance away. They can be seen oriented in long bands parallel to the mountain range, at regular intervals of several kilometres (Figure 6). On satellite images, they form a streamline pattern. Figure 6. WebbAn automated method producing a diagnostic of the severity of lee waves and their impacts on surface winds as represented in output from a high resolution linear numerical model (3D velocities over mountains (3DVOM)) covering several areas of the U.K. is discussed.
