| 摘 要： | 采用分层浅水波方程和ＷＫＢ方法，分别讨论了在基流垂直切变和地形的影响下，二维惯性重力波的稳定性及其发展，并根据理论结果试图解释１９９２年６月２１日发生在京津冀的一次飑线演变与惯性重力波之间的关系，这可能为飑线预报提供一种思路

| Abstract: | By using the shallow water equations and WKB methods,the stability and development of the inertia gravitational waves are discussed in effects of the vertical shear of basic flow and the topography with west east direction.According to the conclusions,the relationship between squall line's varying and the wave's development are tried to illustrated,which happened in the area of Beijing Tianjin Hebei on June 21,1992.It may provide a few thinkings for forecast the squall line. |
