| 摘 要： | 本文推导了等压面坐标系下受周年热源强迫的简单大气超长波动力系统,并用数值求解方法结合非线性分析方法,研究讨论系统中某特定参数值和非绝热强迫型式的变化对系统周期和浑沌行为的影响。其结果指出非绝热强迫型式的不同,系统的行为显著不同;对于一定型式的强迫,在较小的耗散参数下,系统在较大的稳定度参数范围内更易出现分叉和达得混沌状态。

| Abstract: | In this thesis, the simple ultra-long wave system, consisting of ann- ual periodic diabatic forcing, is arrived, and its chaotic and periodic behavior is studied by means of the methods of numerical integratation and nonlinear dynamic analysis. The effection of change of values in some parameters and forcing types on behavior of the simple system are discussed. The results show that the beha- vior of system is different if the types of diabatic forcing are different; In giv- en forcing, the system appears bifurcation and arrives at chaotic state more ea- sier within greater range of stability parameter, when dissipative coefficient is smaller. |
