degree of turbulence的意思|示意

English words degree of turbulence mentioned in aviation and meteorology. In aviation, degree of turbulence refers to the degree of turbulent air movement which is estimated from visual flight observation and expressed as light, moderate, severe and extreme. In meteorology, it is used to measure the difficulty of atmospheric winds.

In aviation, light turbulence is the lowest degree of turbulence, which lessens the sense of motion in the aircraft and does not require passengers to buckle their seatbelts. Moderate turbulence is more intense than light turbulence and safety belts should be buckled. Severe turbulence is very intense and can cause serious injuries to passengers who are not wearing safety belts. Extreme turbulence is the highest degree and can cause structural damage to the aircraft.

In meteorology, the degree of turbulence is used to evaluate the level of difficulty of the winds in the atmosphere. Generally, degree of turbulence is defined as the ratio of air speed to wind speed in the upper level of a certain range. When the ratio is between 0.1 and 0.2, the degree of turbulence is mild; when the ratio is between 0.2 and 0.3, the degree of turbulence is moderate; when the ratio is between 0.3 and 0.4, the degree of turbulence is strong; when the ratio is higher than 0.4, the degree of turbulence is very strong.

Therefore, degree of turbulence is used to measure the turbulence of air movement in aviation and the difficulty of wind in meteorology. Knowing the degree of turbulence is useful for pilot to take precautionary measures to ensure the safety of passengers, and for meteorologist to make accurate weather forecast.
