Perturbation method of studying the EI Niño oscillation with two parameters using delay sea—air oscillator model 下载免费PDF全文
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. 相似文献

Asymptotic solution for a class of sea-air oscillator model for El Nin^~o-southern oscillation 下载免费PDF全文
The El Nifio-Southern Oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific Oceanatmosphere interactions. In this paper, an asymptotic method of solving the nonlinear equation for the ENSO model is used. And based on a class of oscillator of ENSO model, the approximate solution of a corresponding problem is studied by employing the perturbation method. Firstly, an ENSO model of nonlinear time delay equation of equatorial Pacific is introduced, Secondly, by using the perturbed method, the zeroth and first order asymptotic perturbed solutions are constructed. Finally, from the comparison of the values for a figure, it is seen that the first asymptotic perturbed solution using the perturbation method has a good accuracy. And it is proved from the results that the perturbation method can be used as an analytic operation for the sea surface temperature anomaly in the equatorial Pacific of the atmosphere-ocean oscillation for the ENSO model. 相似文献

Homotopic method of solving a class of EI Nino/La Nina-Southern Oscillation sea-air oscillator 下载免费PDF全文
The EI Nino/La Nina-Southern Oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific Ocean-atmosphere interactions. In this paper, an asymptotic method of solving the nonlinear equation for the ENSO model is created. And based on a class of oscillator of the ENSO model, the approximate solution of a corresponding problem is studied by employing the method of homotopic mapping. It is proved from the results that the homotopic 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

In this paper, a coupled system of sea-air oscillator model is studied. The aim is to create an asymptotic solving method of nonlinear equation for the ENSO model. And based on a class of oscillators of ENSO model, employing the method of homotopic mapping, the approximate solution of corresponding problem is studied. It is proven from the results that the homotopic 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 ENSO model. 相似文献

A time delay equation for the sea--air oscillator model is studied. The aim is to
create an asymptotic solving method of nonlinear equation for the El Ni\tilde{\rm
n}o--Southern Oscillation model. And based on a class of oscillators of the
model, employing the method of ENSO singular perturbation, the asymptotic solution
of corresponding problem is obtained. It is proven from the results that the method
of singular perturbation can be used for analysing the sea surface temperature
anomaly in the equatorial eastern Pacific of the atmosphere--ocean oscillation for

In this paper, a class of coupled system for the El Ni no/La Ni na southern oscillation (ENSO) atmospheric physics oscillation model is considered. We propose an ENSO atmospheric physics model using a method from the asymptotic theory. It is indicated from the results that the asymptotic method can be used for analyzing the sea surface temperature anomaly and the thermocline depth anomaly of the atmosphere-ocean oscillation for the ENSO model in the equatorial Pacific. 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

eastern Pacific and the thermocline depth anomaly of the

A sea—air oscillator model is studied using the time delay theory. The aim is to find an asymptotic solving method for the El Ni no-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

Numerical Analysis of the Mixed 4th-Order Runge-Kutta Scheme of Conditional Nonlinear Optimal Perturbation Approach for the EI Niño-Southern Oscillation Model 下载免费PDF全文
Xin Zhao Jian Li Wansuo Duan & Dongqian Xue 《advances in applied mathematics and mechanics.》2016,8(6):1023-1035
In this paper, we propose and analyze the mixed 4th-order Runge-Kutta
scheme of conditional nonlinear perturbation (CNOP) approach for the EI Niño-Southern
Oscillation (ENSO) model. This method consists of solving the ENSO model
by using the mixed 4th-order Runge-Kutta method. Convergence, the local and global
truncation error of this mixed 4th-order Runge-Kutta method are proved. Furthermore,
optimal control problem is developed and the gradient of the cost function is
determined. 相似文献
