热带太平洋海区混沌特征分析
Analysis of the Chaotic Characteristics of the Tropical Pacific Ocean
摘要
Abstract
Based on TOGA-TAO data and the methods for studying no nlineardynamical systems-power spectrum, state space reconstruction, calculati on of Lyapunov exponents and fractal dimensions, the ocean chaotic characteristics of the tropical Pacific ocean is extensively studied in this paper. It is found that the underlying system of the eastern and western Pacific is always chaotic and a strong chaotic region exists in the eastern Pacific ocean between 130° W~120°W. The largest Lyapunov exponent is about 9.39618E-04h-1 in the eastern Pacific ocean and 6.561212E-04h-1 in the western Pacific ocean. The Fractal dimension is 4.3414±0.02 in the easern Pacific ocean and 4.3241±0.0 2 in the western Pacific ocean. The difference between the characteristics of chaotic attractors existing in the eastern and western tropical Pacific ocean shows that the reason for the chaos present in the two regions may be different.关键词
