本文研究了一类具有时滞的厄尔尼诺-南方波涛动模型.得到了该模型在平衡点稳定的充分条件.通过选择时滞η为分岔参数,得到了当时滞η通过一系列的临界值时,Hopf分岔产生,然后,应用中心流形和规范型理论,得到了确定Hopf分岔特性(例如Hopf分岔方向和分岔周期解的稳定性以及Hopf分岔周期解的周期等)的计算公式.最后进行数值模拟验证了所得结果的正确性. In this paper, we study a class of El Ni --Southern Wave Oscillation models with time delay, and obtain the sufficient condition for the model to stabilize at equilibrium. By choosing the time delay η as the bifurcation parameter, , Hopf bifurcation is generated. Then, the calculation of the Hopf bifurcation characteristics (such as the stability of Hopf bifurcation direction and bifurcation period solution, the period of Hopf bifurcation period solution, etc.) is obtained by using the center manifold and the canonical form theory Finally, numerical simulations verify the correctness of the results obtained.
