摘要
作者应用动力学分析方法,结合观测飞机颠簸的事实,对高空急流区飞机颠簸的一种形成机理进行了理论探讨。结果表明,高空急流区温度平流分布的不均匀性,会在急流附近等温线密集区边缘激发出空气垂直运动和湍流,引起飞机颠簸。
By using dynamical analysis technique and combining with observational facts of airplane turbulence,a formation mechanism on airplane turbulence in upper jet stream is studied.The results show that the inhomogeneous distribution of temperature advection in upper jet stream trigger vertical currents in the marginal area of upper jet stream and cause airplane turbulence.
