Sea-air oscillator model for equatorial eastern Pacific SST
赤道东太平洋SST的海-气振子模型

A sea-air oscillator model of the nonlinear coupling system is studied. Using the variational iteration principle, a series of corresponding functional is constructed. Then the Lagrange operators are selected. Finally, using the generalized variational iteration method, the approximate sequences of a series of solutions for the sea-air oscillator model are obtained.
