Regarding clouds, which statement is accurate?

Cumulonimbus clouds are indeed associated with thunderstorms, making the statement accurate. These clouds are known for their towering height and are capable of producing severe weather conditions, such as heavy rain, lightning, and even tornadoes. The vertical development of cumulonimbus clouds allows them to reach into the higher altitudes of the atmosphere, where they can generate significant weather phenomena.

Understanding the characteristics of cumulonimbus clouds is critical for pilots and weather observers, as their presence signals the potential for turbulent weather. This contrasts with other cloud types, which may not have the same severe implications.
