They're sometimes called "UFO" clouds because of their rounded, saucer-like shapes and hovering behavior. They've been around as long as any other kind of clouds, and were "officially" described/catalogged in the mid 1800s - long before HAARP or even use of electricity by humans. Much earlier records (paintings, text, etc.) no doubt exist as well. In the scientific world, they're known as Lenticular clouds (Altostratus lenticularis), or "standing wave" clouds, and generally form over, downwind of, or sometimes upwind of mountain ranges. This event occured in the afternoon and evening of March 9th, 2010 and provided some spectacular skies around sunset. The cause is interesting... Fluid dynamics also apply to air, since wind moves much like water; it flows over the surface of the earth and when it encounters surface features (like mountains) it flows up and over them, like boulders in a river, generating ripples/rapids in the airstream above and downwind. Unlike water, these air currents are normally invisible, unless clouds exist to make them visible. Lenticular clouds form when moist air from lower altitude is forced up into colder, lower pressure layers of the atmosphere where it condenses, usually at the peaks of the air rapids and waves. As the air descends down from the peaks, it warms and evaporates. The result is a cloud that remains mostly stationary while any <b>...</b>
