摘要
研究简单海气耦合模式大气运动方程非线性对ENSO循环的影响,即讨论大气运动方程的纬向非线性、经向非线性、纬向和经向非线性对ENSO循环的影响。同时,讨论了ENSO循环对大气运动方程非线性的敏感性问题。数值实验证明,大气运动方程的非线性对ENSO循环的影响明显,并且ENSO循环对大气运动方程的非线性非常敏感。因此,研究简单海气耦合模式中大气运动方程的非线性对ENSO循环的影响,对进一步理解ENSO循环的物理机制,具有一定的理论意义和实用价值。
Based on a simple coupled ocean atmosphere model, the influences of nonlinear factors on ENSO cycles are investigated when zonal or meridional factors or both of them are considered in governing equations for the atmosphere. At the same time, the sensitivity of ENSO cycles to nonlinear factors of governing equations for the atmosphere is further discussed. It is proved by results of numerical tests, the influences of nonlinear factors of governing equations for the atmosphere on ENSO cycles are obvious, and ENSO cycles are very sensitive for nonlinear factors. Therefore, it has a certain theoretical meaning and practical value to study the influences of nonlinear factors of governing equations for the atmosphere on ENSO cycles for further understanding of the cyclic mechanisms of ENSO.
