What are Clouds? - Types & Facts

Instructor: Jeff Fennell

Jeff has a master's in engineering and has taught Earth science both domestically and internationally.

In this lesson we will go over the different types of clouds and with what type of weather they are associated. You can also test your knowledge after with a quiz.

On almost any given day, you may have noticed that there are several different types of clouds. The clouds on a sunny day look a little different than those on rainy days or those during thunderstorms. The variety of clouds is caused by different conditions in the atmosphere, and they can indicate upcoming weather.

Types

Low Clouds

Stratus

Stratus clouds are white or grey clouds that usually blanket the entire sky. They can also look like fog that does not reach the ground. Stratus clouds usually don't produce much rain, although they can produce light rain occasionally.

Middle Clouds (6,000 - 20,000 ft.)

Altostratus

Higher up are grey, middle-level clouds. Altostratus clouds are composed of water droplets and sometimes look like rolling waves. On warm summer morning, if these clouds are present, it often means thunderstorms may occur by late afternoon, though this isn't as common as it is with Cumulus clouds.

Altocumulus

These clouds align into rows and are caused by convection in the atmosphere. If these clouds are present in the morning, there is a good chance of a thunderstorm in the afternoon.

High Clouds

Cirrus

Cirrus clouds are thin clouds blown by high winds into long streams. Sometimes the clouds can form streams thousands of miles long. They form above 20,000 feet (6,000 mi.). In terms of weather, they tend to occur on pleasant, mild days.
