摘要In this paper, it is analyzed the statistical characteristics of inter-annual change of floods/droughts in floods season (JJA) and annual precipitation amount in the southern parts of Yangtze River in China for the average of 16 stations during 1982 similar to 2005, and the significance relationship between floods/droughts (JJA) and annual precipitation and northernmost declination of the moon in summer that were discovered. The correlation coefficient (r) and the correlation probability (P) of anomalous between precipitation in summer (JJA) for average of 16 stations in the southern parts of Yangtze River and northernmost declination of the moon in summer during 1982 similar to 2005 that is very high, r = 0.812, P = 100% (24/24), the significance level is over 0.001. This obvious correlation result proves that inter-annual variations of northernmost declination of the moon in summer have important influence on rainfall in southern parts of China. We have also investigated the causality, it shows differential at the chart of summer (JJA) mean 500 hPa for 11 years (1992 similar to 2002) of rainy and floods with northernmost declination of the moon in summer is in southern 25-.5 degrees N, the west Pacific subtropical high (WPSH) is partial wester ten longitude than for 11 years average of 8 years (1984 - 1991) and 3 years (2003 similar to 2005) of dry and droughts with northernmost declination of the moon in summer is in northern 25.5 degrees N, the westerly circulation of first chart is southern than second chart, the longitudinal wave at Eurasia of first chart is stronger than second chart. The circulation pattern of first chart is of benefit to rainfall of the southern parts of China. Contrary, atmospheric circulation situation of second chart without the benefit of precipitation in the southern parts of China. It illuminated that inter-change of northernmost declination of the moon in summer inference to precipitation by atmospheric circulation.
