| 摘 要： | 在南北向低空急流下,通过简单二层模式讨论地形起伏对重力惯性波的影响,研究指出:(1)存在一个对重力惯性波稳定度无影响的函数和不产生不稳定重力惯性波地形函数;(2)地形起伏越大,不稳定重力惯性波越强;(3)无论南风或北风基流,都是南坡比北坡更有利于产生不稳定重力惯性波。最后,通过实例计算表明,动力分析结果与实况有较好的一致性。

| Abstract: | Using simple two layer model, the influence of terrain to inertia-gravity wave for the lower tropospheric jet stream is studied. The results exhibit that:
( 1 ) There exist an ineffective terrain height for the stability of inertia-gravity wave and a terrain height that does not produce unstable inertia-gravity wave.
( 2 ) The steeper the terrain is, the stronger the unstable inertia-gravity wave becomes. ( 3 ) The south slope side is more favourable in producing the unstable wave in spite of the wind from north or south. Finally, the calculation results show that analysis of dynamics is in good agreament with the observations. |
