Approximate analytic solution of a class of atmosphere-ocean coupled oscillator mechanism for globe climate

考虑了一个全球气候两半球间气-海热盐循环(THC)的箱域模型.利用同伦映射方法,研究了一类简化型非线性模型.得到了模型的近似解.同伦映射求解方法是一个解析方法,得到的解还能继续进行解析运算.从而可再研究有关物理量的各种定性、定量的性态.

A box model of the interhemispheric thermohaline circulation （THC） in atmosphere-ocean for globe climate is considered. By using the homotopic mapping method, a class of simplified nonlinear model is studied, and the approximate solution is obtained. The homotopic mapping is an analytic method, which gives solutions that can be analytically operated subsequently to show diversified qualitative and quantitative behaviors of corresponding physical quantities.
