The suffix 'nimbus,' used in naming clouds, means?

The suffix 'nimbus' in cloud nomenclature specifically denotes a cloud that is associated with precipitation, particularly rain. This term originates from Latin, where 'nimbus' directly translates to "rain." Thus, when you see 'nimbus' in the name of a cloud, it indicates that this cloud type is capable of producing rain.

For example, cumulonimbus clouds are known for their towering vertical development and are often responsible for thunderstorms and heavy rainfall, further validating the association of 'nimbus' with precipitation. Understanding this terminology helps pilots recognize the potential weather patterns and conditions they may encounter while flying.
