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 (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 ...
Cumulonimbus clouds. September 19, 2023: Cumulonimbus clouds rise behind wind turbines in Big Spring, Texas. Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and ...
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]
Flammagenitus cloud above the 2014 Oregon Gulch Fire in Oregon and California, 2014. Aircraft is an F-15C Eagle. Flammagenitus is often grayish to brown in color because of the ash and smoke associated with the fire. It also tends to expand because the ash involved in the cloud's formation increases the amount of condensation nuclei.
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. The name mammatus is derived from the Latin mamma ...
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 .
