Altocumulus Castellanus is a family B typecloud. // High-level clouds Cirrus Clouds (from above) Abbreviation: Ci Cirrus clouds form above 16,500 feet (5,000 m), in the cold region of the troposphere. ... Cumulonimbus capillatus incus floating over Swifts Creek, Victoria in Australia A cloud is a visible mass of condensed droplets or frozen crystals suspended in the atmosphere above the surface of the Earth or another planetary body. ...
Altocumulus Castellanus is named for its tower-like projections that billow upwards from the base of the cloud. The base of the cloud can form as low as 2,000 metres (6,500 feet), or as high as 6,000 metres (20,000 feet). metre or meter, see meter (disambiguation) The metre is the basic unit of length in the International System of Units. ... A foot (plural: feet) is any of several old units of distance or length, measuring around a quarter to a third of a meter. ...
Castellanus clouds are evidence of mid-atmospheric instability and a high mid-altitude lapse rate. They may be a harbinger of bad weather and, if surface-based convection can connect to the mid-tropospheric unstable layer, continued development of castellanus clouds can produce cumulonimbus clouds and thunderstorms. The lapse rate is the rate at which an atmospheric variable (usually temperature) decreases with altitude. ... A harbinger is a sign of things to come. ... Convection is the transfer of potential energy, for example heat, by currents within liquids and gases. ... The Troposphere is the lowermost portion of Earths atmosphere. ... Cumulonimbus (Cb) is a type of cloud that is tall, dense, and involved in thunderstorms and other bad weather. ... It has been suggested that Squall be merged into this article or section. ...
Altocumulus Castellanus clouds can indicate rough turbulence for aircraft. In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic, stochastic property changes. ...
A group of cumulus congestus clouds viewed from midway from the summit of Mount Kinabalu.
Cumulus congestus clouds are characteristic of unstable areas of the atmosphere which are undergoing convection.
Cumulus congestus clouds are formed by the development of cumulus mediocris generally, though they can also be formed from altocumuluscastellanus or stratocumulus castellanus as well.
A cloud is a visible mass of condensed droplets or ice crystals suspended in the atmosphere above the surface of the Earth or another planetary body.
Cloud droplets tend to scatter light very efficiently, so that the intensity of the solar radiation decreases with depth into the cloud, hence the grey or even sometimes dark appearance of the clouds at their base.
Thin clouds may appear to have acquired the color of their environment or background, and clouds illuminated by non-white light, such as during sunrise or sunset, may be colored accordingly.
