Here, we report an attempt of quantitative \nclimate reconstruction covering the main part of north-central China, \nby combining historical drought/flood index and tree-ring data. \nThe rigorous verification tests confirm the fidelity of transfer functions \nused in the reconstructions. The precipitation and temperature \nanomalies/intervals were then defined based on the reconstructions. \nFinally, the intensity of several big droughts recorded in historical \ndocuments was re-examined and the dominant and recessive patterns of \nheat/water changes within the study area were identified. We concluded \nthat (1) the droughts, occurred during the years of 1484 AD, 1585-1587 AD, \n1689-1691 AD, 1784-1786 AD and 1876-1878 AD, were the results of rainless \nand torrid combination; (2) the droughts, occurred during the years of \n1560-1561 AD, 1599-1601 AD, 1609 AD, 1615-1617 AD, 1638-1641 AD \nand 1899-1901 AD, were first caused by rainless summer, and then \ncontrolled by low precipitation and/or high temperature; (3) the droughts, \noccurred during the years of 1527-1529 AD, 1720-1722 AD, 1813-1814 AD, \n1856-1857 AD and 1926-1930 AD, were first caused by torrid summer, \nand then controlled by both low precipitation and high temperature; \n(4) the dominant climate pattern within the study area consisted\nof warm-dry and cold-wet alternations, and the recessive pattern \nconsisted of cold-dry and warm-wet alternations. We also showed that \nthe drought/flood index is a valuable climate proxy in quantitative \nreconstructions, especially in places where tree-ring data is not available. \n\n","author":null,"citation":"Yi, L., H.
