Wind turbulence is greater on
A
Rough surface
B
Smooth surface
C
Undulating surface
D
None of the above
Explanation: 

Detailed explanation-1: -The stronger the wind speed (generally, a surface wind of 20 knots or higher is required for significant turbulence), the rougher the terrain and the more unstable the air, the greater will be the turbulence. Of these factors that affect the formation of turbulence, stability is the most important.

Detailed explanation-2: -The clouds with the greatest turbulence are cumulonimbus clouds. Cumulus clouds are often a sign of good weather, but when cumulus clouds are filled with water vapor, they turn from puffy, fluffy white clouds into darkening storm clouds.

Detailed explanation-3: -Although, it may “feel” like we face more turbulence when flying over water bodies, it is not really so. Unless, of course, we are passing through a patch of cyclonic weather. In general, chances of turbulence are highest when we pass over mountains or cities with high-rises.
