Short summary
Using reconstructed extreme drought/flood chronologies and grain harvest series derived from historical documents, it is found that the frequency of reporting of extreme droughts in any subregion of eastern China was significantly associated with lower reconstructed harvests during 801–1910. The association was weak during the warm epoch of 920–1300 but strong during the cold epoch of 1310–1880, which indicates that a warm climate might weaken the impact of extreme drought on poor harvests.
