摘要: 从Saltzman海气随机气候模式出发,得到了海温脉动θ'的Langevin方程以及对应的Fokker-plank方程。在给定参数条件下求数值解,得到的概率密度曲线p(x,t)具有多个极大值,并在p(x,t)-p(x,t+τ)相空间中呈现Cantor集合图象,表明该随机系统在上述参数条件下出现了混沌行为。Abstract: Usirig the Saltzman sea-air stochastic climate model the Langevin equation for sea-air fluctuation θ' and the related Fokker-plank formulation were derived numerical solutions obtaind in terms of specified parameters, the probability density curve p(x,t) is found to be of a number of maxima and a Cantor set image is shown in the phase space of p (x,t) and p(x,t+τ), suggesting that the stochastic system produces chaos output with the defined parameters.
