Based on the daily precipitation data of the 35 meteorology stations in the Haihe River Basin from 1961 to 2018, this study analyzed the spatial-temporal characteristics of the precipitation in different magnitudes in the Haihe River Basin by the methods of innovative trend analysis, the Mann-Kendall nonparametric test and the Pettitt test. The influences of sunspots and anomalous atmospheric circulation factors on the precipitation were explored using the cross wavelet analysis method. The results showed that, from 1961 to 2018, the precipitation in the Haihe River Basin shows a decreasing trend. The decreasing trend of light precipitation is not significant and the change of heavy precipitation shows a decreasing trend of more than 10%. Precipitation in spring and autumn has an increasing trend, while that in summer and winter shows a decreasing trend. The precipitation declines from the south to the north. The spatial-temporal change characteristics of summer and annual precipitation in the Haihe River Basin are similar. Due to topographic factors, it is rainy in front of the mountain, which is bounded by Taihang Mountains and Yanshan Mountains. In spring and autumn, more precipitation is in the south and less precipitation in the middle of the Haihe River Basin. Sunspots and anomalous atmospheric circulation factors have exerted strong influences on the precipitation changes. Sunspot has the most significant effect on the precipitation, followed by AO and ENSO, and PDO has the weakest effect.
