Explanation:
Detailed explanation-1: -An analysis of these data has indicated that for the higher altitudes (50, 000 to 75, 000 feet), turbulence is both less frequent and less severe than for the lower altitudes (20, 000 to 50, 000 feet). Turbulence appears to be present at the high altitudes (60, 000 to 75, 000 feet) less than 1 percent of the time.
Detailed explanation-2: -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.
