在混沌动力系统相空间重构的基础上,利用关联维数法和最大Lyapunov指数法,对平潭浪高时间序列进行混沌特性识别,并进行了预测。结果表明,浪高时间序列存在混沌现象,混沌时间序列法可应用于海浪预报的研究。 |
Based on the reconstruction of the chaotic dynamic space, the correlation dimension method and Lyapunov exponent method are applied to identify the chaos of wave amplitude series and predict in Pingtan. Results show that wave amplitude series have chaotic characteristic and chaos time series is feasible to be applied in wave forecast study. |
