Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds. The cumulonimbus base may extend several kilometres (miles) across, or be as small as several tens of metres (yards) across, and occupy low to upper altitudes within the troposphere - formed at altitude from approximately 200 to 4,000 m (700 to 10,000 ft).
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]
Cumulus fractus (WMO genus and species) – ragged detached portions of cumulus cloud. Cumulus humilis (WMO genus and species) – small, low, flattened cumulus, early development. Cumulus mediocris (WMO genus and species) – medium-sized cumulus with bulges at the top. Cumulus pileus (WMO genus and accessory cloud) – capped, hood-shaped ...

Alternate spellings and abbreviations for cumulonimbus flammagenitus that may be found in the literature include Cb-Fg, pyrocumulonimbus, pyro-cumulonimbus, pyroCb, pyro-Cb, pyrocb, and volcanic cb, having developed amongst different specialist groups [8] [20] In the media and in public communications, fire-driven examples are often referred to as fires 'making their own weather'.
A cumulonimbus incus is a mature thunderstorm cloud generating many dangerous elements. Lightning: this storm cloud is capable of producing bursts of cloud-to-ground lightning. Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft).
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.
According to a recent study published in Nature Communications Earth & Environment, researchers found that shallow cumulus clouds will dissipate when only a portion of the sun is obscured during ...
