| 摘 要： | 结合太阳活动变化分析,介绍了Morlet小波变换方法在气象时间序列周期分析和突变分析中的应用,对太阳黑子活动得出了一些有意义的结果。分析发现,太阳活动存在14.5 a和106 a的变化周期,其中14.5 a周期最为显著。太阳活动强弱变化存在一定的阶段性,在近258 a发生过6次突变。

| Abstract: | With the analysis of solar activity variation,the Morlet wavelet transform method was introduced to analyze the periods and abrupt change in meteorological time series,and some results about sunspots activity were given out.The sunspot number changed with periods of 14.5 and 106 years,and 14.5-year period was prominent especially.There were strong or weak phases in the change of sun activity, and six abrupt changes occurred in recent 258 years. |
