中文摘要:
      本文在半地转近似[1]下,采用相平面方法[2]讨论了纬向基本气流对线性和非线性地形Rossby波的稳定性及解的性质的影响。结果指出:线性和非线性稳定性判据形式一样,纬向气流及其切变对稳定性有明显影响;在非线性近似下,可形成孤立波槽和孤立波脊。
英文摘要:
      The effects of zonal flow on the stability of linear and nonlinear orographic Rossby waves and their solutions by adopting the phase plane method under the semi-geostrophic approximation are discussed in this paper. It is shown that the criterion of nonlinear stability of the waves is the same as that of linear stability, and the effects of zonal flow and its shear on the wave stability are obvious; under the nonlinear approximation solitary wave troughs and solitary wave ridges are formed.
