A high, atmospheric detached cloud characterized by thin hairlike strands. The name comes from the Latin word for hair.

Characterized by thin white sheets made of regularly arranged grains or ripples.

Characterized by a smooth, transparent sheet covering part or all of the sky. This cloud type can cause a halo around the sun.

This cloud type has a large vertical length that forms huge mountains. Most of these clouds are flat and spread out at the top, sometimes known as the thunderstorm cloud.

Grey cloud layer associated with rainfall or snowfall. The layer of cloud is normally thick enough to block out the sun.

Characterized by patches and sheets formed from rounded masses, layers or rolls. They can be diffuse or made of fibers.

Greyish or bluish sheets which cover all or part of the sky. Unlike Cirrostratus, this cloud type does not cause a halo to form around the sun.

This cloud type has a large vertical length that forms huge mountains. Most of these clouds are flat and spread out at the top, sometimes known as the thunderstorm cloud.

Detached, fluffy clouds with clearly defined edges. The bases of these clouds are flat and gray, while the top forms brilliant white bulges that can look like cauliflower.

Grey or white patches and layers formed by groups of rounded masses. Stratocumulus clouds are normally non-fibrous.

A low, smooth sheet of grey cloud which is often associated with precipitation. These clouds often block the sun.
