CUMULIFORM Clouds composed of water droplets that exhibit vertical development. The density of the droplets often blocks sun light, casting shadows on the earth's surface. With increasing vertical height, they are often associated with convection.

crystals or the mixture of both with its base above the surface of the Earth. It can be classified according to the height of its base (low, middle or high) or to the type of development, which can be horizontal ( stratiform) or vertical ( cumuliform).
