Cumulonimbus (from Latin cumulus 'swell' and nimbus 'cloud') is a dense, towering, vertical cloud, [1] typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents.
Cumulus congestus clouds compared against a cumulonimbus cloud in the background. Due to reflectivity, clouds cool the earth by around 12 °C (22 °F), an effect largely caused by stratocumulus clouds. However, at the same time, they heat the earth by around 7 °C (13 °F) by reflecting emitted radiation, an effect largely caused by cirrus clouds.
Turkey tower is a slang term for a narrow, tall, individual towering cloud from a small cumulus cloud which develops and suddenly falls apart. [7] Sudden development of turkey towers could signify the breaking or weakening of a capping inversion , [ 8 ] and an area where these consistently form is an "agitated area", a term that applies to ...
Towering vertical clouds have the greatest ability to produce intense precipitation events, but these tend to be localized unless organized along fast-moving cold fronts. Showers of moderate to heavy intensity can fall from cumulus congestus clouds. Cumulonimbus, the largest of all cloud genera, has the capacity to produce very heavy showers.
the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles
Cumulonimbus pileus (WMO genus and accessory cloud) – capped, hood-shaped cloud above a cumulonimbus cloud. Cumulonimbus praecipitatio (WMO genus and supplementary feature) – Cb whose precipitation reaches the ground. Cumulonimbus tuba (WMO genus and supplementary feature) – column hanging from the bottom of cumulonimbus. Debris cloud ...
A hot tower is a tropical cumulonimbus cloud that reaches out of the lowest layer of the atmosphere, the troposphere, and into the stratosphere. [1] These formations are called "hot" because of the large amount of latent heat released as water vapor that condenses into liquid and freezes into ice within the cloud.
The transport of heat in the Hadley circulation's ascending branch is accomplished most efficiently by hot towers – cumulonimbus clouds bearing strong updrafts that do not mix in drier air commonly found in the middle troposphere and thus allow the movement of air from the highly moist tropical lower troposphere into the upper troposphere ...
