【摘要】：为了研究太阳高纬度和低纬度活动现象在南北半球的混沌与分形特征,结合递归分析方法与Grassberger-Procaccia算法两种技术对1952年2月至1998年6月的极区光斑和黑子数目两种太阳磁活动指标进行了详细分析和比较.主要结论如下:1)由于太阳活动现象与磁场的时空演化密切相关,导致太阳活动在南半球和北半球的混沌与分形特征具有不对称性,太阳高纬度和低纬度活动现象的混沌与分形特征具有差异性;2)太阳高纬度活动现象比低纬度活动现象具有更强的混沌程度和更复杂的分形结构,其中太阳高纬度活动现象在北半球具有最强的混沌程度和最复杂的分形结构.
[Abstract]:In order to study the chaos and fractal characteristics of solar high and low latitudes in the northern and southern hemispheres, Combined with recursive analysis method and Grassberger-Procaccia algorithm, two kinds of solar magnetic activity indexes of polar spot and number of sunspots from February 1952 to June 1998 are analyzed and compared in detail. The main conclusions are as follows: (1) because the solar activity is closely related to the evolution of the magnetic field, the chaos and fractal characteristics of the solar activity in the southern and northern hemispheres are asymmetric. The chaos and fractal characteristics of solar high latitude and low latitudes are different. 2) the solar high latitude activity has more chaotic degree and more complex fractal structure than the low latitude active phenomenon. The high latitude solar activity has the strongest degree of chaos and the most complex fractal structure in the Northern Hemisphere.
