Altocumulus cloud
Encyclopedia
Altocumulus is a cloud
belonging to a class characterized by globular masses or rolls in layers or patches, the individual elements being larger and darker than those of cirrocumulus and smaller than those of stratocumulus. Like other cumulus clouds, altocumulus signifies convection. It is usually white or gray, and often occurs in sheets or patches with wavy, rounded masses or rolls. Altocumulus often are seen preceding a cold front, and their presence on a warm, humid, summer morning frequently signals the development of thunderstorms later in the day.
One form of altocumulus, altocumulus lenticularis (Lenticular cloud
) can resemble flying saucers and may be occasionally be mistaken for "unidentified flying object
s". Altocumulus generally forms about 6,500 feet to 20,000 feet (1,200 to 6,100 meters) above ground level.

A cloud is a visible mass of liquid droplets or frozen crystals made of water and/or various chemicals suspended in the atmosphere above the surface of a planetary body. They are also known as aerosols. Clouds in Earth's atmosphere are studied in the cloud physics branch of meteorology...
