厄尔尼诺/拉尼娜-南方涛动是涉及赤道太平洋中的一个海-气交互的年际现象.本文的目的是建立一类海-气振子模型的非线性奇摄动问题的渐近求解方法.并在一类海-气振子模型的基础上,借用奇摄动方法研究了对应问题的近似解.由奇摄动方法得到的结果分析厄尔尼诺/拉尼娜-南方涛动海-气振子模型的赤道太平洋的海表温度异常和气-海振子的温度深度异常.
The El Niño / La Niña-Southern Oscillation is an interannual event involving a sea-air interaction in the equatorial Pacific.The purpose of this paper is to establish an asymptotic solution to a class of nonlinear singularly perturbed problems in the sea-gas oscillator model, Based on a kind of sea-gas oscillator model, the approximate solution of the corresponding problem is studied by the singularly perturbed method.The results from the singularly perturbed method are used to analyze the sea of the El Niño / La Niña-Southern Oscillation sea-gas oscillator model over the equatorial Pacific Table temperature anomalies and gas - sea oscillator temperature anomalies.
