STANDING LENTICULAR ALTOCUMULUS CLOUDS. In short, energy is produced by air moving over the summit which is then transmitted upward through the . Like ocean waves, these waves of air bouncing over the mountains are anything but stable. As such glider pilots tend to seek them out. Billow clouds form due to KH waves. Destructive turbulence from the rotor rarely exists more than 2,000-3,000 feet above mountaintop level. Aviators are advised to stay well clear. Lenticular clouds can actually be quite dangerous for pilots of powered aircraft due to the turbulence created above them. 60 Best National Geographic Channel Images National Geographic Channel National Geographic Wonders Of The World Answer (1 of 8): No, there doesn't seem to be any connection between the hexagonal clouds and the disappearances of ships and aircraft in the region known as Bermuda Triangle. The formation of lenticular clouds is influenced by orographic factors or elevation. But first: A quick review of stability: . could be dangerous when it erupts, sending thousands of residents to various . Wicked cool wave clouds crash over Boston area. The first is a lenticular cloud, which looks like this: Wikipedia. "Thunderclouds" are known scientifically as cumulonimbus clouds. Like ocean waves, these waves of air bouncing over the mountains are anything but stable. Pilots of aircraft that are powered will try to avoid lenticular as they harbour potentially dangerous turbulence. Lenticular Clouds: Calm in Appearance, Dangerous in Reality.Lenticular clouds indicate great instability in that layer of the atmosphere, and form in areas of mountain waves. However, according to Gadjah Mada University (UGM), lenticularis clouds are dangerous for flight activities because they can cause turbulence.. Their formation may also be associated with severe tropospheric storms. . Rotor clouds are turbulent, ragged-looking clouds that form at low altitude under the crests of mountain waves. Interestingly though, glider pilots use the turbulence to their advantage. How to Read the Clouds at Mt.

Likewise, are lenticular clouds dangerous? Standing lenticular clouds are associated with a phenomenon known as mountain wave turbulence. If enough moisture is present, standing lenticular clouds can form to give a visual indication of the wave action. Lenticular clouds - pretty but dangerous. Since weather systems and associated precipitation usually move in from the south and west, look south (see photo 1) and if it is clear, it indicates dry weather for the next twenty-four hours.
