In meteorology, a
cloud is a
visible mass of liquid droplets or frozen crystals made of water or various chemicals
suspended in the atmosphere above the surface of a planetary body. These
suspended particles are also known as aerosols and are studied in the cloud
physics branch of meteorology. Terrestrial cloud formation is the result of air
in Earth's atmosphere becoming saturated due to either or both of two
processes; cooling of the air and adding water vapor. With sufficient
saturation, precipitation will fall to the surface; an exception is virga,
which evaporates before reaching the surface.
