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.
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.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
The lenticular clouds form at the peak of the waves (B). Over elevated surfaces, heating of the ground exceeds the heating of the surrounding air at the same altitude above sea level, creating an associated thermal low over the terrain and enhancing any lows which would have otherwise existed, [19] [20] and changing the wind circulation of the ...
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.
Cloud chart showing major tropospheric cloud types identified by standard two-letter abbreviations and grouped by altitude and form. See table below for full names and classification. The table that follows is very broad in scope much like the cloud genera template near the bottom of the article and upon which this table is partly based.
Lenticular clouds form when strong northwesterly winds flow up and over the mountain range, creating a standing wave. The air cools as it rises, and the water vapour in the air condenses to form clouds. The Taieri Pet cloud formation can sometimes appear in layers and has been described as a "huge stack of plates" in the sky.
Not typically associated with severe weather but are notable for their unusual, UFO-like appearance. Virga clouds The setting sun illuminates virga falling from clouds over a paddle boarder on ...
