    Indicates that the air below the cloud is dry; can also signify the downdraft region of a storm. Wall clouds. A supercell forms and a wall cloud pushes north of Beardstown, Ill. Friday, March 31 ...

    en.wikipedia.org/wiki/Cumulonimbus_capillatus

    A cumulonimbus capillatus is a cumulonimbus cloud with dense cirrus clouds above it, making the cloud top appear to contain hair-like structures. The name comes from the Latin word capillatus, meaning "with hair". [1] It is an intermediate stage between cumulonimbus calvus and cumulonimbus incus.

    en.wikipedia.org/wiki/Cumulonimbus_incus

    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).

    Landspout; Cumulonimbus calvus clouds can, on rare occasions, produce a unique type of tornado known as a landspout. Landspouts are formed when strong ground level rotation is caught in the updraft of the storm, pulling it upwards and connecting it to the clouds above resulting in the rotation becoming a true tornado.

  6. Cumulonimbus cloud - Wikipedia

    en.wikipedia.org/wiki/Cumulonimbus_cloud

    Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.

  7. Arcus cloud - Wikipedia

    en.wikipedia.org/wiki/Arcus_cloud

    A shelf cloud is a low, horizontal, wedge-shaped arcus cloud attached to the base of the parent cloud, which is usually a thunderstorm cumulonimbus, but could form on any type of convective clouds. Rising air motion can often be seen in the leading (outer) part of the shelf cloud, while the underside can often appear as turbulent and wind-torn.

  8. Thunderstorm - Wikipedia

    en.wikipedia.org/wiki/Thunderstorm

    A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning [1] and its acoustic effect on the Earth's atmosphere, known as thunder. [2] Relatively weak thunderstorms are sometimes called thundershowers. [3] Thunderstorms occur in a type of cloud known as a cumulonimbus. [4]

  9. Wall cloud - Wikipedia

    en.wikipedia.org/wiki/Wall_cloud

    Attached to many wall clouds, especially in moist environments, is a cauda [1] (tail cloud), a tail-like band of cloud extending from the wall cloud toward the precipitation core. [6] It can be thought of as an extension of the wall cloud in that the tail cloud is connected to the wall cloud and condensation forms for a similar reason.
