| 摘要: |
| 从适于研究深对流运动的柱坐标系非弹性近似(anelastic apptoximation)方程组出发,利用WKBJ方法导出了包含径向辐合辐散及垂直运动的、非梯度风平衡、非静力平衡、非轴对称三维非均匀时变涡旋基流上扰动的波作用量方程,并对中尺度扰动的发展作了定性讨论。 |

| Abstract: |
| In this article, starting from the anelastic equations describing deep convection in cylindrical coordinates, the WKBJ method is used to discuss the stability of asymmetric three-dimensional nonhomogeneous vortex under the conditions of nonhydrostatic and non-equilibruim gradient wind. From the equation of wave action, the development of disturbance is qualitatively analysed. |
