The Effect of Topographic Forcing on the Instability of Inertia Gravitational Waves in Basic Flow of Vertical Shear
-
摘要: 利用分层浅水波方程和小参数(WKB)方法，考虑具有垂直切变的基流和地形的作用，求得惯性重力波的局地频率方程，并根据此方程分析讨论了在多种环境条件下波动的稳定性情况。Abstract: By using the shallow-water wave equation and WKB method (small parameter method), the local frequency equation of the inertia gravitational waves is obtained, which includes the effects of the basic flow with vertical shear and the mountain range with east-west direction. The instability of the waves is discussed through the equation under different environment conditions.
