摘要
描述了一类厄尔尼诺/拉尼娜-南方涛动(ENSO)动力系统。首先求得了退化模型的解,其次对方程的时滞函数作了处理,然后利用摄动方法得到了对应问题的渐近解。最后,研究了模型的参数对振子系统的影响并做出了对应的曲线图形,同时对系统的物理量的变化作了描述。
A class of El Nino/La Nina-Southern Oscillation (ENSO) dynamic system is described. Firstly, the reduced solution to dynamic system was got. Secondly, the time delay function of equation was managed. Then the asymptotic solution to the corresponding problem was obtained by employing the perturbation method. Finally, the parameters of the dynamic system were studied and the curve figures of the solution were obtained. And the physical qua nt ities of the dynamic system were illustrated.
