When a cloud forms in space, it is known as an interstellar cloud, or a nebula. Three components are necessary for clouds to form: water vapor, cool or cold air, and condensation nuclei. A white cloud means that the cloud was formed with warm air. A grey, or a black cloud, means that the cloud contains larger drops of water. There are four main types of clouds:
A large dark cloud charged with electricity and producing thunder and lightning; a cumulonimbus cloud.
a dark cloud of great vertical extent charged with electricity; associated with thunderstorms
