Question

What are dark cumulus clouds called?

Answer 1

Dark cumulus clouds are often referred to as "cumulus congestus" or "cumulonimbus" clouds, depending on their development. Cumulus congestus is a type of cumulus cloud that is taller and denser than typical cumulus clouds and may indicate the potential for rain. If these clouds continue to develop vertically and become more organized, they can evolve into cumulonimbus clouds, which are thunderstorm clouds associated with heavy precipitation, thunderstorms, and severe weather. These clouds typically appear darker due to the thickness of the water droplets they contain.
