A lenticular cloud covers the summit crater of Mayon Volcano, Philippines.. As air travels along the surface of the Earth, obstructions are often encountered, including natural features, such as mountains or hills, and artificial structures, such as buildings and other constructions, which disrupt the flow of air into "eddies", or areas of turbulence.
Lens-shaped middle cloud. Includes informal variant altocumulus Kelvin–Helmholtz cloud, lenticular spiral indicative of severe turbulence. Altocumulus volutus (V-27) Elongated, tube shaped, horizontal stratocumuliform cloud. Altocumulus castellanus (V-28) Turreted layer cloud. Altocumulus floccus (V-29) Tufted stratocumuliform clouds with ...
Cirrocumulus lenticularis is a type of cirrocumulus cloud. The name cirrocumulus lenticularis is derived from Latin, meaning "like a lentil". [1] Cirrocumulus lenticularis are smooth clouds that have the appearance of a lens or an almond. They usually form at the crests of atmospheric waves, which would otherwise be invisible.
The cloud base on the leeward side is higher than on the windward side, because precipitation on the windward side removes water from the air. [1] It is possible that simple convection from mountain summits can also form wave clouds. This occurs as the convection forces a wave or lenticular wave cloud into the more stable air above. [2]
If the air is generally stable, nothing more than lenticular cap clouds will form. However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear. [18] Windy evening twilight enhanced by the Sun's angle, can visually mimic a tornado resulting from orographic lift
An Air Force investigation later concluded that what Arnold really saw were disc-shaped wave clouds called lenticular clouds, which are not Lenticular clouds, sometimes mistaken for UFOs, are in a ...
If the air is generally stable, nothing more than lenticular cap clouds form. However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear. [21] Clouds formed by any of these lifting agents are initially seen in the troposphere where these agents are most active.
