The type of cloud commonly associated with thunderstorms is cumulonimbus. These towering, dense clouds are capable of producing severe weather events, including heavy rainfall, strong winds, and lightning. Cumulonimbus clouds can develop rapidly, reaching heights of several kilometers in the atmosphere. They are characterized by their anvil-shaped tops and can extend into the stratosphere. As they develop, they undergo different stages, forming the basis for severe storms and sometimes leading to phenomena such as hail and even tornadoes. Meteorologically, they are crucial for understanding and predicting storm patterns.
