What type of cloud is typically associated with thunderstorms?

Cumulonimbus clouds are the type typically associated with thunderstorms. These clouds are large, towering formations that can reach high altitudes and have a characteristic anvil-shaped top. They are capable of producing severe weather phenomena, including heavy rain, strong winds, lightning, hail, and even tornadoes.

The development of cumulonimbus clouds is fueled by warm, moist air rising rapidly in an unstable atmosphere, which contributes to the formation of thunderstorms. As the air rises, it cools, leading to condensation and the development of the cloud structure. Cumulonimbus clouds can also extend through the troposphere, reaching heights where atmospheric conditions can drastically change, enabling powerful storm systems to form.

In contrast, while cumulonimbus clouds are specifically linked to thunderstorms, the other types of clouds listed have different characteristics and are not associated with severe thunderstorm activity. For instance, cumulus clouds are typically puffy and indicate fair weather, cirrus clouds are high-altitude wispy clouds that generally indicate a change in weather but not severe storms, and nimbostratus clouds produce steady, continuous precipitation but lack the violent characteristics associated with thunderstorms.
