Evolution of the Asian summer monsoon and regional karst ecological environment since the middle ages in Southwest China.

ABSTRACT: The frequent droughts and floods, closely associated with the Asian summer monsoon (ASM), has profoundly affected the ecological environment and economy in East Asia. While changes in the ASM are closely related to precipitation patterns, the specific mechanism still requires further investigation. This study utilized stalagmite records from the Feilong Cave in southwest China to reconstruct the evolution of the ASM since the Medieval Warm Period (MWP). The results indicated that the ASM strengthened during the MWP and weakened during the Little Ice Age (LIA), with changes in monsoon intensity primarily driven by solar activity and variations in tropical ocean-atmosphere circulation.
