Cumulus arcus clouds have a gust front, [26] and cumulus tuba clouds have funnel clouds or tornadoes. [27] Cumulus pileus clouds refer to cumulus clouds that have grown so rapidly as to force the formation of pileus over the top of the cloud. [28] Cumulus velum clouds have an ice crystal veil over the growing top of the cloud. [19]
Thin scattered wave-cloud resembling cirrocumulus. Low stratocumuliform Wave-cloud resembling stratocumulus, especially as a polar cap cloud over the winter pole which is mostly composed of suspended frozen carbon dioxide. [25] [26] Surface-based Morning fog of water and/or carbon dioxide commonly forms in low areas of the planet.
Trade wind cumulus (or trade cumulus) clouds are formed by cooling and moisture absorption of the dry trade winds over the relatively cold sea surface in the eastern parts of the oceans. [ 2 ] [ 3 ] These are clouds , typically Cumulus humilis or Cumulus mediocris , which are considered as fair weather clouds.
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 ...

Cumulus clouds have a significant impact on transport of energy and water vapor, and then influence precipitation and climate. In large scale models, cumulus clouds need to be parameterized. Entrainment rate is a key parameter in cumulus parameterization. Henry Stommel was the first to study entrainment rate in cumulus clouds. [4]
Cirrocumulus undulatus is a variety of cirrocumulus cloud. The name cirrocumulus undulatus is derived from Latin, meaning "diversified as with waves". [1] They have a rippled appearance due to wind shear and usually cover only a small portion of the sky. They appear in bands as small patches or layers.
Although horizontal convective rolls, also known as cloud streets, have been clearly seen in satellite photographs for the last 30 years, their development is poorly understood, due to a lack of observational data. From the ground, they appear as rows of cumulus or cumulus-type clouds aligned parallel to the low-level wind.
