The Periodic Solution Problem of the 11-yr Solar Cycle Forced El Ni(n)o and Southern Oscillation(ENSO) System with Generalized Nonlinear Damping Term
摘要
Abstract
The periodic solution problem of an El Ni(n)o and southern oscillation (ENSO) is investigated.Firstly,the 11-yr solar cycle forced ENSO system with generalized nonlinear damping term is established.Secondly,the exact solution of the corresponding undamped system is obtained,and the result about the nonexistence of periodic solution of the corresponding autonomous system is obtained.Thirdly,the result about the existence of periodic solution of the system is obtained by using Mawhin's continuation theorem.The significance is that we generalize the existing results of the literature.Finally,an example is given to illustrate that our results are right.关键词
