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.
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.

Atmospheric internal waves can be visualized by wave clouds: at the wave crests air rises and cools in the relatively lower pressure, which can result in water vapor condensation if the relative humidity is close to 100%. Clouds that reveal internal waves launched by flow over hills are called lenticular clouds because of their lens-like ...
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 ...
Stratocumulus lenticularis is an uncommon cloud type that belongs to the stratocumulus cloud type, its appearance is that of a flat lens or almond.It forms as a result of atmospheric waves [1] caused by wind passing over obstacles; for example, a mountain or a building.
Altocumulus lenticularis (Ac len lenticular cloud) is a lens-shaped middle cloud which can resemble flying saucers and may occasionally be mistaken for "unidentified flying objects". This is formed by uplift usually associated with mountains. but usually with at least some grey shading.
A pileus (/ ˈ p aɪ l i ə s /; Latin for 'cap'), also called scarf cloud or cap cloud, is a small, horizontal, lenticular cloud appearing above a cumulus or cumulonimbus cloud. Pileus clouds are often short-lived, appearing for typically only a few minutes, [ 1 ] with the main cloud beneath them rising through convection to absorb them.
