It is pointed out that vertical wind shear and its change are closely correlated with the temperature advection.

文中指出垂直风切变及其变化与温度平流的存在是紧密相关的。

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.

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。
