The residual chronology of tree-ring width was constructed using collected from the low-altitude valley in the Chayu County, southeastern Tibetan Plateau of China. Pearson correlation analysis was carried out between the residual chronology of tree-ring width and climatic factors. The changes of Palmer drought severity index (PDSI) from April to May between 1812 and 2016 in the southeastern Tibetan Plateau were reconstructed by linear regression method (the variance interpretation was 47%).

- The study utilized tree-ring cores from southeast Shanxi Province to create a tree-ring width chronology to analyze the link between precipitation and tree-ring width.
- Findings indicated a strong correlation (0.636) between the chronology and January-June precipitation, allowing reconstruction of historical precipitation from 1724 to 2019.
- Results showed alternating dry and wet periods over the centuries, with significant cycles in precipitation patterns hinting at relationships with larger climate phenomena like ENSO.
