Earth Science. Cloud formation can be classified as low, medium, high and vertical. How well do you know the different types of clouds? The aim of this article is to help you learn the 4 different types of clouds, as well as the 10 major cloud systems that fall under each category. The cirrocumulus appears to be above a lower layer of much smoother cirrus.

The formation of different types of clouds depends on the speed of the ascending air current.

Cirrostratus clouds indicate upper atmosphere moisture and turbulence, often indicating a change in weather. These clouds are usually no numerous that they are often indistinguishable from one another, thus forming a sheet called cirrostratus. They appear almost like ripples over a small portion of the sky. Clouds may be altocumulus or cirrocumulus if they form at higher altitudes, while those that form near the ground and remain small are cumulus humilis, or fair-weather cumulus clouds. This indicates different wind characteristics in the two layers (probably turbulent at the higher level and much smoother at the lower level). They are the same size or smaller than the width of your littlest finger when you hold up your hand at arm's length. Cirrocumulus are usually white, but sometimes appear gray. A characteristic of this cloud is Coronae - one or more coloured rings around the sun or moon when viewed from below the cloud. Altocumulus clouds exhibit "cumulo" type characteristics (see below) in mid levels, i.e., heap-like clouds with convective elements. The term "mackerel sky" is often used to describe these clouds because of their likeness to fish scales.

Cirrocumulus cloud Characteristics Because of the high altitude, and therefore low temperature, cirrocumulus clouds are composed of ice crystals rather than water particles. Characteristics. Characteristics. By elevation in lee waves or other atmospheric waves.

If these clouds cover a lot of the sky, it is called a "mackerel sky" because the sky looks like the scales of a fish.

Cirrus clouds are those pleasant thin, feather like, wispy like strands, comprised together with multiple tufts, that you see on a cool day.

Cirrocumulus clouds exhibit features from both cumulus and cirrus clouds. Origin: By convection within thin unstable layers. The WMO International Cloud Atlas is the reference for the classification of clouds and meteorological meteors. There are three main types of higher level clouds: cirrus, cirrostratus and cirrocumulus. The clouds are primarily made up of ice crystals, which makes the water in the cloud rapidly freeze, forming cirrostratus clouds and therefore these clouds do not last long.

Cloud Atlas-> Cirrocumulus. Cirrocumulus (Cc) Description: Fleecy cloud; Cloud banks of small, white flakes. Cirrocumulus clouds are small rounded puffs that usually appear in long rows high in the sky.
