Approximate solution of sea-air oscillator for El Ni?o-southern oscillation model
海-气振子厄尔尼诺-南方涛动模型的近似解

A class of time delayed coupled system of the El Ni o-southern oscillation (ENSO) model is considered. By using the homotopic mapping method, the approximate expansion of the solution for the ENSO model is obtained and the asymptotic behavior of solution of corresponding problem is studied.
