http://indem.gob.mx/News/pills-for-long-sexually-p3S-active/ WebbIn 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.

WebbThe latter shows waves which decay down-stream and are contained in a strip, the width of the strip being determined by the radius of the mountain. An interesting result is that the circular mountain can give rise to waves which have greater amplitude than those produced by the infinite ridge under the same conditions.

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.

WebbThe well-known cloud phenomena associated with the waves are briefly described in section 6, and in section 7 the effect of isolated mountains rather than long ridges is considered.
