Non-vertical genus types including some genus sub-types are sorted into approximate descending order of altitude of the cloud bases. These clouds often do not produce precipitation, but larger systems may produce drizzle.
Thicker forms of these clouds often produce continuous light precipitation and hide the sun or moon, though thinner forms show the sun or moon with a ground glass appearance.
Often several types of cloud will be present at different levels of the atmosphere at the same time. For instance, scattered cumulus clouds showing little vertical growth on an otherwise sunny day used to be termed "cumulus humilis" or "fair weather cumulus," although normally they simply are referred to just as cumulus or flat cumulus.
These thick clouds are listed in approximate descending order of altitude of the cloud tops. The constituent varieties and associated supplementary features and mother clouds for each genus or species are arranged in approximate order of frequency of occurrence.
There is a height classification which are called high, middle, and low altitudes. Low-level clouds are not given a prefix, although their names are derived from "strato-" or "cumulo-", depending on their characteristics.
Cirrocumulus Typically found in a similar altitude range to cirrus, these clouds do not produce precipitation and are usually more broken in appearance than cirrus, with the position of the sun or moon being visible.
Layer of stratus clouds on or near the ground. Mammatus most often are seen hanging from the anvil of a severe thunderstorm, but do not produce severe weather. When people stare at the altocumulus clouds, they usually see a shape of an animal, usually an elephant.
This cloud may be at similar altitudes to cirrus cloud due to the lower height of the tropopause at the poles. Vertical or multi-level genera and genus sub-types can be based in the low or middle levels and are therefore placed between the non-vertical low and mid-level genus types and sub-types.
Mid level clouds typically form at temperatures between 0 and —40C depending on altitude and season, so may consist of warm or supercooled droplets and ice particles. In some cases these clouds are also thick enough to hide the sun. The altocumulus, altostratus, and nimbostratus clouds are found in the middle division.
They also may line up in streets or rows of clouds across the sky denoting localized areas of ascent cloud axes and descent cloud-free channels. Within the troposphere, the cloud levels are listed in descending order of altitude range.The modern classification scheme used by the UK Met Office, with similar schemes used elsewhere, classifies clouds according to the altitude of cloud base, there being three altitude classes: low; mid level and high.
сumulunimbus cloud classification by the types of the weather pattern and results of the statistical analysis of the cloud top height and of the precipitation amounts are presented. Keywords for the year describe only 39 cumulonimbus cloud formations.
4 weather patterns with cumulunimbus clouds have been specified: cold. There is a height classification which are called high, middle, and low altitudes. The different kinds of clouds are found in these three divisions according to the clouds' altitude. First, we have the high clouds that range in altitude from 16, to 45, feet.
Investigating the Climate System CLOUDS And the Earth’s Radiant Energy System cloud formation, cloud classification, and the vapor in a cloud, its composition, and its height all affect the amount of the Sun’s radiation that reaches the Earth’s surface.
CLOUD CLASSIFICATION AND OBSERVED PROPERTIES OF CLOUDS (Supplement to Rogers and Yau, Ch. 5.) • Primary classification uses height of cloud base, and depth of cloud – low clouds (water, and ice in upper part if deep enough) CLOUD CLASSIFICATION AND OBSERVED PROPERTIES OF CLOUDS.
Rope cloud (informal term) – A narrow, long, elongated lines of cumulus cloud formation that develop at the leading edge of an advancing cold front or weather fronts that is often visible in satellite imagery.Download
