PSC's show some variation in structure according to their chemical makeup and atmospheric conditions, but are limited to a single very high range of altitude of about 15,000–25,000 m (49,200–82,000 ft) Accordingly, they are classified as a singular type with no differentiated altitude levels, genus types, species, or varieties.
Clouds in the troposphere, the atmospheric layer closest to Earth, are classified according to the height at which they are found, and their shape or appearance. [31] There are five forms based on physical structure and process of formation. [ 32 ]
These clouds are the highest in the atmosphere and are given the Latin-derived name noctilucent which refers to their illumination during deep twilight rather than their physical forms. They are sub-classified alpha-numerically and with common terms according to specific details of their physical structures.
Cloud with limited vertical height with a length much bigger than their height: Cu Lenticularis: len: Lens or almond shaped clouds that are stationary in the sky: Sc, Ac, Cc Mediocris: med: Clouds of moderate height that are around equal height and length, growing upwards: Cu Nebulosus: neb: Featureless sheet of cloud with no structure: St, Cs ...
This is the category of types of clouds, their microphysical, thermodynamical and morphological properties. Notice that Category:Fog and Category: ...
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
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 ...
Mammatus cloud seen at Puthenpeedika, India Mammatus clouds formation in Coimbatore, India Mammatus clouds over the Nepal Himalayas. Mammatus (also called mamma [1] or mammatocumulus, meaning "mammary cloud") is a cellular pattern of pouches hanging underneath the base of a cloud, typically a cumulonimbus raincloud, although they may be attached to other classes of parent clouds.
