The results show that the nonlinear instability of system can appear in certain parameter region 表明了在一定的条件下,系统将出现非线性不稳定,这构成了论文的第二章。
When the atmosphere system occurs nonlinear instability in the subcritical instability region , it will split more wave resolutions than in the supercritical instability region and need more time to occur the subcritical instability , therefore it may have effect on the form and development of some synoptic system . 3 . starting from nonlinear equations on the f - plane containing frictional dissipation under the boussinesq approximation 大气系统在亚临界不稳定区发生非线性不稳定时,会比超临界不稳定区分裂出更多的波动解,而且发生亚临界不稳定需要更长的时间,因此它可能在某些天气系统的形成和发展过程中起到一定的作用。
