An annually resolved and absolutely dated ring-width chronology spanning 657yrs was constructed withPinusbungeanazucc.samples from the southernTaihang Mountains,eastern China.On the basis of a significant correlation between the tree-ring width index and observed instrumental data,precipitation in current May was reconstructed since AD 1510 for the region,with predictor variables accounting for 37.9%of the variance in precipitation data.In agreement with other drought reconstructions,notable dry spells occurred in the 1630s-1650s,1680s-1700s,and 1770s-1800s,whereas wet periods prevailed in the 1530s-1570s,1840s-1870s,and 1950s-present.
