摘要
本文主要研究了斜压基本气流中中尺度对称型扰动发展的问题,旨在揭示中尺度扰动发展的内在本质。文中应用WKB方法,分析了二维动量无辐散近似下的扰动方程。结果是,中尺度扰动波包对称发展的原因是基本场的不均匀热成风偏差和非定常性。
The effects of baroclinic basic flow on a paralleled mesoscale disturbance development are researched. Using WKB method, the two dimensional purturba-tion equations with the non-momentum-divergence approximation are analyzed. The result indicates that the symmetric development of a mesoscale disturbance is due to the non-homogeneous thermal deviations and unstationality of the basic field.
