Webb1 apr. 2015 · Leaky trapped mountain lee waves are investigated by examining the structure of individual linear modes in multilayer atmospheres. When the static stability and cross-mountain wind speed are constant in the topmost unbounded layer, modes that decay exponentially downstream also grow exponentially with height. 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 …

"Webb1 sep. 2013 · While linear theory is known to severely underestimate the disturbances associated with trapped lee waves for sufficiently high mountains ( Vosper 2004 ), it can provide a benchmark for the behavior of the drag, against which existing numerical simulations may be compared and new ones planned in a more rational way.

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.
