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 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. Cumulus ...
Cumulus and cumulonimbus clouds formed by quickly generated ground heat; including forest fires, volcanic eruptions and low level nuclear detonation. Accepted as a WMO genitus cloud with the Latin name flammagenitus , or homogenitus in the case of small cumulus formed by contained human activity.
Cumulus congestus or towering cumulus clouds are a species of cumulus that can be based in the low- to middle-height ranges. They achieve considerable vertical development in areas of deep, moist convection. They are an intermediate stage between cumulus mediocris and cumulonimbus, sometimes producing rainshowers, snow, or ice pellets. [2]
Cloud with limited vertical height with a length much bigger than their height: Cu Lenticularis: len: Lens or almond shaped clouds that are stationary in the sky: Sc, Ac, Cc Mediocris: med: Clouds of moderate height that are around equal height and length, growing upwards: Cu Nebulosus: neb: Featureless sheet of cloud with no structure: St, Cs ...
A flanking line often has a stairstep appearance where the tallest cells are connected to the main cumulonimbus. [1] The bases of the clouds making the flanking line are merged. The forefront area usually has no precipitation. In the picture, it is possible to detect precipitation in the background just above the horizon below the main cloud.
A tornado is a dangerous rotating column of air in contact with both the surface of the Earth and the base of a cumulonimbus cloud (thundercloud), or a cumulus cloud in rare cases. Tornadoes come in many sizes but typically form a visible condensation funnel whose narrowest end reaches the earth and is surrounded by a cloud of debris and dust.
A genus of cloud characterized by thin, wispy, feather-like strands that appear white or light grey in color and form at very high altitudes, usually between 5 and 13.7 km (16,000 and 45,000 ft) above sea level. Cirrus clouds often develop from the outflow of cumulonimbus clouds in advance of fronts or thunderstorms, and therefore may indicate ...
