摘要
从适于研究深对流运动的柱坐标系非弹性近似（ａｎｅｌａｓｔｉｃａｐｐｔｏｘｉｍａｔｉｏｎ）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．
In this article, starting from the anelastic equations describing deepconvection in cylindrical coordinates, the WKBJ method is used to discuss thestability of asymmetric three-dimensional nonhomogeneous vortex under theconditions of nonhydrostatic and non-equilibruim gradient wind. From theequation of wave action, the development of disturbance is qualitativelyanalysed.
