What is the characteristic feature of cumulonimbus clouds?

Arab Weather - The distinctive feature of cumulus clouds is their dense and swollen shape with a dome-like top, and they are often of high altitudes starting from the lower layers of the atmosphere and extending upwards. Cumulus clouds are usually formed as a result of warm, humid air rising to the upper layers of the atmosphere, where it cools and condenses, forming these clouds.

Cumulonimbus clouds are also characterized by their ability to generate strong weather phenomena such as thunderstorms, heavy rain, and lightning, especially when they develop into cumulonimbus clouds.
