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.
Low-level clouds usually form below 2,000 m (6,500 ft) and do not have a prefix. [1] [66] The two genera that are strictly low-level are stratus, and stratocumulus. These clouds are composed of water droplets, except during winter when they are formed of supercooled water droplets or ice crystals if the temperature at cloud level is below ...
Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds formed by rising thermals. The term stratus describes flat, hazy , featureless clouds at low altitudes varying in color from dark gray to nearly white. [ 2 ]
A stratocumulus cloud, occasionally called a cumulostratus, belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower height, usually below 2,000 metres (6,600 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 ...
Stratocumulus volutus is a rare species of stratocumulus cloud, typically forming alone. [1] Volutus is translated from Latin, meaning revolve, being described as a roll cloud . [ 2 ] [ 3 ] Stratocumulus volutus clouds are low-level clouds, forming below 2,000 meters (6,600 feet).
Clouds and high winds hampered efforts by rangers on Thursday to reach two climbers who remained high up on North America's tallest peak two days after first sending a distress signal. Teams on ...
Heights of various cloud genera including high-, mid-, and low-level clouds. Altostratus and altocumulus clouds are the two genera of mid-level clouds that usually form between 2,000 and 6,100 m (6,500 and 20,000 ft). [4] [39] These are given the prefix "alto-". These clouds are formed from ice crystals, supercooled water droplets, or liquid ...
