摘要
将TOMS测量的5°N纬向平均O3总量逐日序列作相空间拓展,使O3层的行为特征可用相轨迹刻划。首先计算O3层系统吸引子的分数维,而后把相点作为动力学系统的离散特解集合,反演出描述系统状态随时间演化的数学模型中的客观控制参数值,建立起反映热带O3层短期演化特征的非线性动力学系统。
n this paper,the daytoday sequence of the total ozone of 5°N zonal average measured by TOMS is opened up in the phase space,so that the characteristics of the ozonosphere can be described by phase locus.First of all,the fractional dimension of system attractor of the ozonosphere is computed.Then regarding the phase points as the set of special discretion solutions to the dynamic system,the realistic controlled parameters retrieving to the mathematical model which is used to describe the state of system evolution with time are inverted,and the nonlinear dynamic system of which reflected the evolution characteristic fo ozonosphere over tropical area in short periods are est up.
