摘要: 通过实验数学方法、元胞自动机模型(并行算法与实际过程的模拟)、大型转盘模拟实验以及计算机数值模拟(用串行算法模拟时间演化的长期行为)来研究大气系统非线性过程与湍流过程中出现的混沌随时间演化的宏观特性、气溶胶粒子凝聚增长机制,湍流的拟序结构,系统状态在临界点的突变和多重平衡态以及台风的孤立子拓扑性质,促进学科新概念新方法的相互交叉与渗透,从分析、综合上升到整体研究(IntegrativeStudy),在非线性动力学层次上认识大气系统复杂性的本质,这些都是大气科学领域中当前迅速发展的前沿课题,具有重要的科学意义和实际应用价值。Abstract: This paper deals with the macro- properties of chaotic cvolution,growing mechanism with condensation and solidarity of aerosol,coherent structureof turbulence,catastrophe and multiple-balanced states of system at criticalpoints,topological characteristic of Typhoon and soliton appearing in the non-linear and turbulent process of atmospheric system by using experimental mathe-matical method, model of cellular automata(parallel algorithm and analogy topractical process),analogy experiment of large scale annu...
