南北半球太阳耀斑与其降水响应的对比分析

Comparative Analysis of the Solar Flare of the Northern and Southern Hemispheres and Its Precipitation Response

根据南、北半球的降水量和太阳耀斑指数数据,采用非参数统计检验Mann-Kendall法和Db16正交小波分析对南、北半球太阳耀斑和降水的变化趋势及其之间的互相关性进行分析.结果发现:北半球降水总体变化比较平稳,南半球降水在1965年以后有减小的趋势;南、北半球太阳耀斑指数具有10年、18年左右的主周期.通过相关性计算发现,南北半球太阳耀斑对其年际尺度降水的影响并不显著.

According to the index date of precipitation and solar flare in the southern and the northern hemisphere, the change trend of precipitation and solar flare and the mutual relationship in the southern and the northern hemisphere nonparametric are analyzed by the statistical test Mann-Kendall method and Dbl6 orthogonal wavelet analysis. The results show that change of precipitation in northern hemisphere is overall smooth, and the percipitation in the southern hemisphere has the trend of decrease after 1965; northern and southern hemispheres solar flare index has the main period of 10 or 18 years. Through the correlation formula, it is found that northern and southern hemisphere solar flares affect on the annual precipitation indistinctively.
