Abstract
Abstract A time delay equation for sea-air oscillator model is studied. The aim is to create an asymptotic soling method of nonlinear equation for the ENSO model. And based on a class of oscillators of ENSO model, employing the variational iteration method, the approximate solution of corresponding problem is obtained. It is proven from the results that the method of variational iteration method can be used for analyzing the sea surface temperature anomaly in the equatorial eastern Pacific of the atmosphere-ocean oscillation for ENSO model. *Supported by National Natural Science Foundation of China (Grant Nos. 40576012, 90111011), the National Program on Key Basic Research Project (Grant No. 2004CB418304) and in part by E-Institute of Shangai Municipal Education Commission (Grant No. E03004)
