Noctilucent clouds are known to form near the poles at altitudes similar to or higher than the same type of clouds over Earth. [27] High cirriform Thin scattered wispy cloud resembling cirrus through which the planet's surface can be seen. High stratocumuliform Thin scattered wave-cloud resembling cirrocumulus. Low stratocumuliform
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).
A nimbostratus cloud is a multilevel, amorphous, nearly uniform, and often dark-grey cloud that usually produces continuous rain, snow, or sleet, but no lightning or thunder. [ 1 ] [ 2 ] [ 3 ] Although it is usually a low-based stratiform cloud, it actually forms most commonly in the middle level of the troposphere and then spreads vertically ...
That wave cloud pattern formed over the Île Amsterdam, in the lower left corner at the tip of the triangular formation, in the far southern Indian Ocean. A wave cloud is a cloud form created by atmospheric internal waves. Wave cloud pattern in Tadrart region. Unusual wave clouds over the Aral Sea, seen from NASA's Water satellite on March 12 ...
Added to the International Cloud Atlas as a supplementary feature in March 2017, it is the first cloud formation added since cirrus intortus in 1951. [2] The name translates approximately as "roughness". [3] The clouds are closely related to undulatus clouds. [3] Although they appear dark and storm-like, they almost always dissipate without a ...
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.

the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles
