The anvil or mushroom shape is caused due to the strong wind shear or warm air turbulence when the cloud reaches the troposphere. The moisture rapidly cools down and condenses to form tiny drops of water, forming the rising cumulus clouds. Cumulonimbus is abbreviated Cb. Definition: A species of cumulonimbus cloud whose upper portion appears bald and cauliflower-like.

The ‘calvus’ cloud species is one of only two species that’s associated with cumulonimbus clouds. Through the convection precipitation, the air tends to rise in an updraft, resulting in the creation of a low-pressure zone below the developing thunderstorm.

It is often accompanied by lightning, thunderstorms, and severe tornadoes. Cumulonimbus (from Latin cumulus, "heaped" and nimbus, "rainstorm") is a dense, towering vertical cloud,[1] forming from water vapor carried by powerful upward air currents. The tall, column-like appearance, often with a flat top, can indicate severe lightning, heavy rain and high winds.Storm clouds form from rising warm air that cools and creates ice at higher altitudes, or height above ground, and rain at lower levels. They are very dense clouds that soar up to a height of about 15 – 22 km. Description: Clouds of very tall summits, which lack sharp outlines and are not anvil-shaped.

Cumulus clouds are capable of quickly developing into large cumulonimbus clouds, resulting in powerful thunderstorms and Supercells. Most storm cells die after about 20 minutes, when the precipitation causes more downdraft than updraft, causing the energy to dissipate. Another type of rain cloud is the cumulonimbus.
