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. Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel ...
The list of cloud types groups all genera as high (cirro-, cirrus), middle (alto-), multi-level (nimbo-, cumulo-, cumulus), and low (strato-, stratus). These groupings are determined by the altitude level or levels in the troposphere at which each of the various cloud types is normally found. Small cumulus are commonly grouped with the low ...
Cumulus clouds are clouds that have flat bases and are often described as puffy, cotton-like, or fluffy in appearance. Their name derives from the Latin cumulus, meaning "heap" or "pile". [1] Cumulus clouds are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form.
Cumulonimbus incus. A cumulonimbus incus (from Latin incus 'anvil'), also called an anvil cloud, is a cumulonimbus cloud that has reached the level of stratospheric stability and has formed the characteristic flat, anvil -shaped top. [ 1] It signifies a thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage. [ 2]
Nimbostratus ( rain, layered) Altitude. 500–5,500 m. (2,000–18,000 ft) Appearance. Dark and featureless layer cloud full of water vapor; responsible for rain and snow. Precipitation. Yes: rain, ice pellets, or snow; sometimes virga. A nimbostratus cloud is a multilevel, amorphous, nearly uniform, and often dark-grey cloud that usually ...
Cumulonimbus and aviation. Numerous accidents have occurred in the vicinity of thunderstorms due to the density of clouds. It is often said that the turbulence can be extreme enough inside a cumulonimbus to tear an aircraft into pieces, and even strong enough to hold a skydiver. However, this kind of accident is relatively rare.
The cumulonimbus flammagenitus cloud ( CbFg ), also known as the pyrocumulonimbus cloud, is a type of cumulonimbus cloud that forms above a source of heat, such as a wildfire, nuclear explosion, or volcanic eruption, [5] and may sometimes even extinguish the fire that formed it. [6] It is the most extreme manifestation of a flammagenitus cloud.
"Buddy, I’ve been around the world many times when I was a young cumulus nimbus cloud. It’s a wonderful place, filled with wondrous creatures—except dogs. Oh, by the way, don’t eat the ...
