Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of
clouds. Clouds are composed of
microscopic droplets of water (warm clouds), tiny crystals of ice, or both (mixed phase clouds). Under suitable conditions, the droplets combine to form precipitation, where they may fall to the earth. The precise
mechanics of how a cloud forms and grows is not completely understood, but scientists have developed theories explaining the structure of clouds by studying the microphysics of individual droplets. Advances in
radar and
satellite technology have also allowed the precise study of clouds on a large scale.
