Low, Medium, High Brings Different Cloud Types

Altocumulus are often spotted on warm and humid mornings, especially during summer. You may also see them out ahead of cold fronts, in which case they signal the onset of cooler temperatures.

10 cloud types

Clouds of the genus cirrostratus consist of mostly continuous, wide sheets of cloud that covers a large area of the sky. It is formed when convectively stable moist air cools to saturation at high altitude, forming ice crystals. Frontal cirrostratus is a precursor to rain or snow if it thickens into mid-level altostratus and eventually nimbostratus as the weather front moves closer to the observer.

Cloud Facts For Kids

But, we regularly refer to them as a type of cloud, so they’re worth discussing in more detail here. As with noctilucent clouds, polar stratospheric clouds form when small amounts of moisture and dust make their way into the stratosphere on very cold nights in the polar regions. They are considered to be quite rare, though, and you are more likely to see them in the Antarctic than in the Arctic. The problem with cumulonimbus clouds is that they can bring severe weather. Damaging straight-line winds, large hail, lightning, and tornadoes are all possible with these clouds.

Cloud families are based on cloud height; high, middle, or low. There are 10 primary cloud types known as the principal cloud types. However, types of software development at sufficiently cold temperatures, ice crystals may be found in all forms of altocumulus, especially the species castellanus and floccus.


If you’d like to learn even more cloud names, check out What’s This Cloud. Multi-level Clouds are clouds that have a large vertical buildup. They are called multi-level clouds because of their ability to spread through the lower, middle, and upper cloud levels. When first learning cloud names it is advised you concentrate on using only the primary names. As you gain experience and become confident in your ability to name the primary cloud types you may add the species and eventually the variety names if you desire.

They are usually made as result of outflow of tropical cyclones or anvil-top of cumulonimbus cloud. The arrival of cirrus signifies the onset of rains but the cloud itself cannot lead to rain.

  • White, feathery cirrus clouds are the most common cloud type at this altitude.
  • Supplementary features and accessory clouds, however, are not necessarily an integral part of the cloud itself.
  • Plus, knowing how clouds form can help you impress your friends when you’re out and about in the mountains.
  • We break this sometimes tricky concept down so it’s easy to understand in our complete guide to dynamic equilibrium.
  • Low clouds are primarily composed of water droplets since their bases generally lie below 6,500 feet .

One of the most common cloud terms you’ll hear in aviation, cumulus clouds are puffy white clouds. On a nice summer day, you may see small, pretty white clouds that look like cotton balls.

What Are Clouds?

Some of the more common optical effects that you might see with altostratus include cloud iridescence and coronas, so keep your eyes peeled if these clouds are in the sky. Orographic clouds get their shape from mountains or hills that force the air to move over or around them. They can also be formed by sea breezes and often appear as lines where two air masses meet.

The cirrus Principle Cloud Type is made of various cirriform cloud elements which are white, delicate filaments, patches, or narrow bands. The ice crystal particles in cirrus are often large enough to have a significant speed of fall giving the cloud elements considerable vertical extent.

So, all tornadoes are funnel clouds, but not all tornadoes are funnel clouds. A new type of cloud that was first added to the International Cloud Atlas in 2017, the asperitas is a stunning cloud with a wavy pattern. When arcus clouds move overhead, it can look like they’re literally rolling over the ground below. This can make them look quite dramatic, especially when the dark skies of a thunderstorm trail closely behind. However, as we’ve mentioned, lenticular clouds can look suspiciously like a spaceship in low light.

Mixing Up The Main Types

It is a dark, thick layer of clouds, capable of completely blotting out the sun. Starting out as a humble cumulus cloud, strong vertical air movement combined with enough humid air allow this type of cloud to develop. Cumulonimbus clouds are seen as your typical storm clouds.

But they are generally not considered clouds since they are human-made. White/gray patches (turreted, lens-shaped, or balls of cotton), sheets, or structured layer with undulations or rolls. They start at a low Software crisis cloud level and can grow and expand up to the highest level. It is within this space, dominated by updrafts and downdrafts, that all the elements necessary for the development of a storm system are formed.

Wind shear (variations in wind direction and/or speed) cause these fibrous trails to be slanted or curved. Stratus Praecipitatio – A form of stratus cloud that comes with precipitation through ice prisms, snow grains or light drizzles. Most clouds can be divided into groups (high/middle/low) based on the height of the cloud’s base above the Earth’s surface.

10 cloud types

Mediocris – Large, puffy clouds with quite a bit of vertical development . Fractus – Featuring ragged, irregular shapes, fractus clouds are normally small and located under the base of other clouds. Nebulosus – A highly uniform cloud with no distinct details, cloud tufts, whisps, or other features. Nebulosus clouds often look like a fine veil over the sun and they are found in the genera stratus and cirrostratus.

Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands. Under the base of this cloud which is often very dark, there are often low ragged clouds that may or may not merge with the base. They produce precipitation, which sometimes is in the form of virga. Because of the lowering base it is often erroneously called a low-level cloud. Both Altostratus and Nimbostratus can extend into the high level of clouds.
