Lee wave — The wind flows towards a mountain and produces a first oscillation (A) followed by more waves. the following waves will have lower amplitude because of the natural damping. Lenticular clouds stuck on top of the flow (A) and (B) will appear… … Wikipedia
Lee waves — In meteorology, lee waves, are atmospheric standing 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 … Wikipedia
lenticular — Clouds having the shape of a lens or almonds often elongated and usually with well defined outlines. Severe downdrafts, updrafts, and rotor activity are associated with lenticulars, and therefore flying in the vicinity of these clouds should be… … Aviation dictionary
