起伏运动

小扰动理论指出风切变对短周期运动和阻尼起伏运动至半振幅的时间无影响，但起伏频率和阻尼率随风切变而相应地变化。

According to the micro-fluctuation theory the windshear has no influence on the short-period motion and the damped rise-fall motion of the half-amplitude time while the frequency of the rise-fall motion and damping changes in accordance with the windshear .
