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 ...
Rotor clouds have ragged leeward edges and are dangerously turbulent. [4] A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee waves. A pileus or cap cloud, similar to a lenticular cloud, may form above the mountain or cumulus cloud generating the wave.
The Met Office said lenticular clouds combined with the sunrise to create the stunning effect. The clouds tend to form "when air blows across a mountain range in certain circumstances" and when ...
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 ...
The peculiar cigar-shaped cloud is called an altocumulus standing lenticular cloud (ASLC) and is created when winds encounter a steep barrier such as a mountain range, Nasa explained in a statement.
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.
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]
