| 摘 要： | 太阳活动对黄河流域降水有一定影响.引用Morlet小波分析技术,对黄河流域近50年来的降水与太阳黑子的小波系数变化进行分析,表明在1951～1997年期间,黄河流域年降水与太阳黑子在9年时间尺度上呈一定的负相关关系,且降水有1～2年的滞后现象.

| Abstract: | The solar activities might affect precipitation in the Yellow River Basin. The Morlet wavelet method is applied to analyze the changes of wavelet coefficients of precipitation and sunspots at same time scales. The research shows that there are negative correlations between precipitation and sunspots and they are most obvious in 9-year time scale. Furthermore, the precipitation lagged behind the sunspots by 1-2 years. |
