摘要
太阳活动对黄河流域径流有一定影响。本文引用Morlet小波分析技术,对1919年～1997年黄河流域径流与同期太阳黑子9～11年小波系数的变化进行分析,表明黄河流域年径流与太阳黑子在不同时间段表现出不同的相关关系,在9年时间尺度上,1919年～1931年和1957年～1997年两个时段,它们与太阳黑子呈一定的负相关关系,1931年～1957年则表现为正相关关系。
Sun activities affect natural runoff in the Yellow river basin. In the paper, the Morlet wavelet method is applied to analyze the changes of wavelet coefficients of natural runoff during 9~11 year time scales and these relationships with sunspots. The research shows that there are different correlations between runoff and sunspots during different period of times. For example, in 9 year scale, there are negative correlations during 1919~1931 and 1957~1997,while there is positive correlation during 1931~1957.
