The impacts of abnormal solar activities on precipitation and temperature in summer and winter in China are analyzed based on the 10.7 cm solar radio flux data and the precipitation and temperature data of 160 weather stations across China from 1951 to 2000.The results show:(1) In high solar activity years,there occurs more precipitation in summer in the upper and middle reaches of the Yellow River and the Changjiang River,as well as over the Huanghuai region,but there occurs less precipitation in summer in South China and Northeast China.At the same time,there is more precipitation in winter across China.There is higher temperature in winter in North China,especially in Northeast China and Xinjiang,and lower temperature in summer.(2) In low solar activity years,there is more precipitation in summer in South China and the regions north of the Yellow River,while there is less precipitation in summer over the Changjiang River basin and the upper and middle reaches of the Yellow River.In winter,there is less precipitation across China and lower temperature in North China.The close relation of summer precipitation in Northeast China and solar activities is further discussed.
