What Vertical cloud that contains a lot of moisture and is associated with thunderstorms?

The vertical cloud that contains a lot of moisture and is commonly associated with thunderstorms is called a cumulonimbus cloud. These towering clouds can reach high altitudes and are characterized by their anvil-shaped tops. Cumulonimbus clouds are capable of producing heavy rainfall, lightning, hail, and severe weather phenomena like tornadoes. They form when warm, moist air rises rapidly, leading to significant atmospheric instability.
