Abstract

The anomalies of summer rainfall (June–August) for the last 500 years in China have been estimated according to the relationship between the instrumentally observed rainfall and the degrees of floods and droughts for the last 25 years. It is shown that calculated anomalies of average rainfall for 10, 20 and 30 year periods have sufficient accuracies. The long-term climatic variations for the last 500 years are discussed based on the estimated anomalies of summer rainfall of 25 stations over the E part of China for the last 500 years. For example, there were prolonged drought in the N of China at about the end of Ming dynasty, but there were extensive floods in China for the early times of Qing dynasty. The anomalies of rainfall for the last 500 years were averaged along latitude zone and their decade running mean were formed. It was found that the long-term variations are very clear. The 80 year cycle is predominating. Besides, an about 200 year cycle is also shown in the charts of 50-year mean rainfall anomalies. It is indicated that both above mentioned cycles relate closely to the solar activity.
