Short summary
We found that the tree-ring earlywood width (EWW) of Pinus tabuliformis from the eastern Qinling Mountains (central China) showed stronger response to May–July scPDSI than the tree-ring total width and latewood width. Therefore, variations in May–July scPDSI were reconstructed back to 1868 CE using the EWW chronology. The reconstruction exhibited a strong in-phase relationship with the East Asian summer monsoon intensity before the 1940s, which was different from that found in recent decades.
