%X Understanding the dry wet changes in northern and central China under the background of global warming is of great scientific significance for in-depth research on historical climate events. We selected 24 climate proxy indicator sequences that were significantly correlated with the warm season (May September) dry wet changes (self calibrated Palmer Drought Index scPDSI) in the study area, and used nested principal component regression (nested PCR) to reconstruct the dry wet climate changes in the central and northern regions of China over the past 530 years (1470-2012),.
