【摘要】：在正壓流體中,從完整Coriolis力作用下的準地轉位渦方程出發(fā),采用多時空尺度和攝動方法,導出Rossby波振幅演變滿足帶有地形和外源強迫的非線性(2+1)維的Zakharov-Kuznetsov方程.通過分析Rossby波振幅的演變,指出Coriolis力的水平分量、β效應、地形效應及外源是誘導(2+1)維Rossby波產(chǎn)生的重要因素.
[Abstract]:In barotropic fluid, based on the quasi-geostrophic vorticity equation under the action of complete Coriolis force, the method of multiple space-time scales and perturbation is used. The Zakharov-Kuznetsov equation of amplitude evolution of Rossby wave satisfying the nonlinear dimension of 21) with topography and exogenous forcing is derived. By analyzing the evolution of amplitude of Rossby wave, the horizontal component and 尾 effect of Coriolis force are pointed out. Topographic effects and exogenous factors are important factors in inducing the formation of Rossby waves.
