摘　　要：A class of recharge–discharge oscillator model for the El Ni？o/Southern Oscillation （ENSO） is considered. A stable limit cycle is obtained by transforming the ENSO model into the van der Pol-Duffing equation. We proved that there exists periodic oscillations in the ENSO recharge–discharge oscillator model.A class of recharge–discharge oscillator model for the El Ni？o/Southern Oscillation （ENSO） is considered.
