Solution
The cloud types that would be a visual sign of atmospheric turbulence to a pilot during flight are:
-
Rotor clouds: These are associated with severe turbulence. They form under the crests of standing waves in the atmosphere, often in the lee of mountains, and indicate very turbulent air.
-
Lenticular clouds: These are also associated with atmospheric waves and can indicate turbulence. They are lens-shaped and often form over mountains or in areas of stable, fast-flowing air.
-
Cumulonimbus clouds: These are thunderstorm clouds and are associated with severe weather, including turbulence. They are large, towering clouds that can reach high into the atmosphere.
-
Billow clouds: Also known as Kelvin-Helmholtz clouds, these are associated with instability and turbulence at the boundary between two layers of air of different densities.
Cirrocumulus and stratus clouds are generally not associated with turbulence.
