A class of delayed oscillators of El Ni?o-southern oscillation (ENSO) models is considered. Using the delayed theory, the perturbed theory and other methods, the asymptotic expansions of the solutions for ENSO models are obtained and the asymptotic behaviour of solution of corresponding problem is studied. 相似文献

A sea-air oscillator model is studied using the time delay theory.The aim is to find an asymptotic solving method for the El Nio -southern oscillation (ENSO) model.Employing the perturbed method,an asymptotic solution of the corresponding problem is obtained.Thus we can obtain the prognoses of the sea surface temperature (SST) anomaly and the related physical quantities. 相似文献

The EI Ni\~{n}o/La Ni\~{n}a--Southern Oscillation (ENSO) is an
interannual phenomenon involved in the tropical Pacific
ocean--atmosphere interactions. In this paper, a class of coupled
system of the ENSO mechanism is considered. Based on a class of
oscillator of ENSO model, the asymptotic solution of a corresponding
problem is studied by employing the approximate method. It is proved
from the results that the perturbation method can be used for
analysing the sea surface temperature anomaly in the equatorial
eastern Pacific and the thermocline depth anomaly of the
atmosphere--ocean oscillation for the ENSO model. 相似文献

A class of perturbed mechanisms for the western boundary
undercurrents in the Pacific is considered. The model of generalized
governing equations is studied. Employing the method of variational
iteration, an approximate solution of corresponding model is
obtained. It is proved from the results that the solution for the
variational iteration method can be used for analysing operation of
the perturbed mechanism of western boundary undercurrents in the
Pacific. 相似文献
