The Western Sichuan Plateau, situated at the southeastern edge of the Tibetan Plateau, serves as a critical transition zone between the plateau and the Sichuan Basin, where alpine ecosystems converge with the eastern monsoon climate system. Its high climate sensitivity and complex variability render it indispensable for climate change research. Understanding historical climate patterns and driving mechanisms here under global warming is vital for predicting global climate trends.

Wu Xu (first author, 2021 graduate now at Dazhou Meteorological Bureau), supervised by Professor Li Jinjian (corresponding author) and Dr. Cui Linlin (co-corresponding author), recently published “A 219-year tree-ring evidence revealing the influence of the Atlantic Multi-decadal Oscillation on annual mean temperature in the northern Western Sichuan Plateau” in Climate Dynamics. This study reconstructed annual mean temperatures (1800-2018) using tree-ring data from the region’s north, analyzing mechanisms through which AMO influences local temperatures.
