【摘要】：回复性是动力系统的一个基本性质,用来描述系统的动力学行为.递归图及其回复性量化分析作为研究系统动力学行为的重要工具,受到大量学者的关注.它们被广泛的应用到地球科学,神经科学,气象学等学科中.公海地区的降水数据是东亚夏季风变化行为的重要指标,东亚夏季风的变化对该地区的水文和环境有直接影响.研究公海地区降水数据,不仅对了解典型时段该区气候演化过程具有重要意义,而且对认识华北地区自然环境格局的演变历史提供科学依据.本文利用递归图及其回复性量化分析方法对公海地区的降水数据进行了深入的研究,直观地反映了公海地区东亚夏季风变化行为的重要时期,分析了东亚夏季风的动力学行为.首先,介绍了研究公海地区降水数据的意义,时间序列的概念及其发展,递归图及回复性量化分析.其次,介绍了回复性分析中参数选取的方法.再次,对公海降水时间序列进行回复性分析,揭示了该地区东亚夏季风转变过程中的重要时期及演化规律.最后,对主要研究内容进行了总结,并对回复性分析在时间序列方面的研究进行了展望.
[Abstract]:Reversibility is a basic property of dynamic system, which is used to describe the dynamic behavior of the system.As an important tool to study the dynamic behavior of systems, recursive graphs and their reversibility quantitative analysis have attracted a lot of attention.They are widely used in earth science, neuroscience, meteorology and other disciplines.The precipitation data in the high seas area is an important indicator of the variation of East Asian summer monsoon, and the change of East Asian summer monsoon has a direct impact on the hydrology and environment of this area.The study of precipitation data in the high seas area is of great significance not only to understand the climatic evolution process in typical periods of time, but also to provide scientific basis for understanding the evolution history of natural environment pattern in North China.In this paper, the precipitation data in the high seas area are deeply studied by using the recursive graph and its reversibility quantitative analysis method, which directly reflects the important period of the East Asian summer monsoon variation behavior in the high seas area, and analyzes the dynamic behavior of the East Asian summer monsoon.Firstly, the significance of studying precipitation data in high seas, the concept and development of time series, recursive graph and quantitative analysis of reversibility are introduced.Secondly, the method of parameter selection in reversibility analysis is introduced.Thirdly, the time series of high seas precipitation is analyzed to reveal the important period and evolution law of East Asian summer monsoon transition in this area.Finally, the main research contents are summarized, and the research on time series of reversibility analysis is prospected.
