中文摘要:
      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.
英文摘要:
      By using the shallow-water equations and WKB methods,the stability and development of the inertia gravitational waves are discussed in effect of the vertical shear of basic flow and the topo graphy with west-east direction.A ccording 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 thinking s for forecast the squall line.
