【 摘 要 】

The relationship between total annual precipitation and solar activity (sunspot number) were studied based on annual precipitation data from 25 weather stations in Poland that were gathered from 1966 to 2016. The correlation between a yearly sunspot number and a total annual precipitation were analysed by sinusoidal repression analysis. The 5-year smoothest sunspot number and a total annual precipitation for each weather station were taken for final analysis. The parameters of sin curve were calculated by the least square fit method. It is assumed that the frequency is 10.87 years which is a mean spring tidal period of Jupiter and Saturn. The cross correlation between solar activity and total annual precipitation was shown. The difference in year between a minimum yearly sunspot number and a maximum total annual precipitation is assumed as the level of correlation. It is also assumed that high correlation occurs if the difference in question is smaller than 1.5 years, moderate if the difference is higher than 1.5 and smaller than 2.5 years and weak if the difference is higher than 2.5 years. The southern and southwestern regions of Poland give high correlation, central and northern-moderate, and eastern-weak correlations. The presented analysis may be treated as the first step for a more accurate multi-scale harmonic analysis.
