What type of weather conditions are cumulonimbus clouds associated with?

Cumulonimbus clouds are towering clouds often associated with severe weather phenomena. They are typically characterized by their large vertical development and can reach heights of up to 60,000 feet. These clouds are well-known for their ability to produce severe thunderstorms, which can include heavy rain, lightning, strong winds, hail, and even tornadoes.

When conditions are favorable for convective activity, cumulonimbus clouds develop and signify instability in the atmosphere. This instability leads to the rapid upward movement of warm, moist air, which contributes to the intense weather that can accompany these clouds. The structure of cumulonimbus clouds can also lead to phenomena like supercell thunderstorms, which are particularly notorious for their potential to cause devastating weather events.

In contrast, the other options describe weather conditions typically associated with different types of clouds or atmospheric phenomena. For example, clear skies and mild temperatures correspond to other cloud types or high pressure systems, while light rain and overcast conditions are more closely related to stratus or nimbostratus clouds. Fog and humidity are tied to low-lying cloud cover and stagnant air rather than the vigorous updrafts and violent weather patterns associated with cumulonimbus clouds. Thus, the association of cumulonimbus clouds with severe thunderstorms and severe
