Perturbation method of studying the EI Niño oscillation with two parameters using delay sea–air oscillator model

doi:10.1088/1674-1056/21/9/090201

Abstract The EI Niño-southern oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific ocean-atmosphere interactions. In this paper, we develop an asymptotic method of solving the nonlinear equation using the ENSO model. Based on a class of oscillator of the ENSO model, a approximate solution of the corresponding problem is studied employing the perturbation method.
