Which cloud type is characterized by the greatest turbulence?

Cumulus
Cumulonimbus
Stratus
Nimbostratus

The correct answer is: Cumulonimbus

Cumulonimbus clouds are characterized by the greatest turbulence among cloud types. These massive, towering clouds can extend vertically over 40,000 feet and are associated with severe weather phenomena such as thunderstorms, strong winds, and even tornadoes. The intense updrafts and downdrafts within a cumulonimbus cloud create a highly turbulent environment, making them particularly hazardous for pilots. Unlike other cloud types, such as cumulus, stratus, and nimbostratus, which generally produce stable weather conditions and less turbulence, cumulonimbus clouds are dynamic structures filled with convective activity. This turbulence results from the rapid changes in temperature and pressure within the cloud, leading to the potential for significant in-flight disturbances. Understanding the characteristics of these clouds is essential for flight safety and navigation.
