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.
This will give the altitude of the cloud base in feet above ground level. Put in a simpler way, 400 feet for every 1°C dew point spread. For metric divide the spread in °C by 8 and multiply by 1000 and get the cloud base in meters. Add the results from step (2) to the field elevation to obtain the altitude of the cloud base above mean sea level.
Stratus clouds are low-level clouds characterized by horizontal layering with a ... The ice crystals in these clouds vary depending upon the height in the cloud ...
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 ...
They usually form in the low level of the troposphere except during conditions of very low relative humidity, when the clouds bases can rise into the middle-altitude range. Cumulus mediocris is officially classified as low-level and more informally characterized as having moderate vertical extent that can involve more than one altitude level. [7]
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 ...
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).
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).
