太阳活动的小波分析
Wavelet Analysis of Solar Activity
摘要：
利用小波分析方法，从太阳黑子数的逐日时间序列中分析了太阳活动在几天到几十年时间尺度上的时间变化。一个层次结构的变化复杂的时期仔细检测和相关的周期相比，从最近的类似分析的结果。根据从局部子波功率图中提取的子波振幅分布，提出了主要Schwabe周期长度变化的一般确定方法。
英文摘要：
Using wavelet analysis approach, the temporal variations of solar activity on time scales ranging from days to decades, are examined from the daily time series of sunspot numbers. A hierarchy of changing complex periods are careful detected and related cycles compared with results from recent similar analyses. A general determination of the main Schwabe cycle length variations is also suggested on the basis of the wavelet amplitude distribution extracted from the local wavelet power map.
