从含ekman摩擦的二层非线性准地转斜压涡度方程出发，提出了一种新的广义能量作为lyapunov函数，导出了非线性斜压亚临界稳定性判据。该判据含有两个不等式： ( 1 ) - Then numerical experiments on forcing dissipation and heating response of dipole ( unipole ) are carried out using global spectral model of quasi - geostrophic barotropic vorticity equation . for every experiment model integration is run for 90 days on the condition of three waves quasi - resonance . the results are given as follows : ( 1 ) under the effects of basic flow intensity and dipole ( unipole ) forcing source , there exist strong interaction among the three planetary waves , and there also exist quasi - two - week and intra - seasonal oscillation of the three planetary waves
然后，用数值试验的方法，应用强迫耗散准地转正压涡度方程的全球谱模式，并在方程中考虑了偶(单)极子的热力强迫作用，在三个行星波准共振的条件下，模式共积分90d ，得出： ( 1 )在基本气流强度和偶(单)极强迫热源的共同作用下，三个行星波之间存在很强的波?波相互作用，且波动振荡呈现准双周和季节内振荡。
