Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
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]
The list of cloud types groups all genera as high (cirro-, cirrus), middle ... Lower-based convective clouds that can produce thunderstorms. [32] See also. Cloud species;
A low, horizontal, wedge-shaped cloud, usually associated with a thunderstorm gust front. Created by cold air from a thunderstorm downdraft spreading out and lifting warm, moist air.
The wall cloud forms near the downdraft/updraft interface. This "interface" is the area between the precipitation area and the precipitation-free base. Wall clouds form when rain-cooled air from the downdraft is pulled into the updraft.
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning [1] and its acoustic effect on the Earth's atmosphere, known as thunder. [2] Relatively weak thunderstorms are sometimes called thundershowers. [3] Thunderstorms occur in a type of cloud known as a cumulonimbus. [4]
An arcus cloud is a low, horizontal cloud formation, usually appearing as an accessory cloud to a cumulonimbus. Roll clouds and shelf clouds are the two main types of arcus clouds. They most frequently form along the leading edge or gust fronts of thunderstorms ; some of the most dramatic arcus formations mark the gust fronts of derecho ...
If the cold front is highly unstable, cumulonimbus clouds producing thunderstorms commonly form along the front. Anvil cirrus clouds may spread a considerable distance downwind from the thunderstorms. [6] The other cloud types associated with a cold front depend on atmospheric conditions such as airmass stability and wind shear. [7]
