| 摘 要： | 本文利用二维约化摄动方法推导出垂直切变风场中声重波的 KdV 方程。从而进一步证明中尺度 TID 的激发源是声重波这一尚未弄清的问题。另外,本文推导出的方程还可作研究声重波远场处的相互作用、能量交换及不稳定性等特征的出发方程。

| Abstract: | Using the two-dimension reductive perturbation method in this paper,we derive the KdV equation of an acoustic gravity wave in the vertical shear wind,and prove that the AGW is the excited source of the medium scale TID.In addition,starting from the KdV equation,we can also investigate the in- teraction,energy exchange and the instability of an AGW at the far fields. |
