Here we present, to date, the highest-resolved (~5 years) and most precisely-dated Holocene monsoon climate reconstruction for the western Chinese Loess Plateau (CLP) based on five replicated stalagmite δ18O records from Wuya Cave, eastern Gansu, China. Our record suggests the wettest period occurred between 10500 and 6600 a BP in this region. After this period, the amplitude of Asian summer monsoon (ASM) decadal-scale variability progressively increased likely in response to increasing ENSO frequency since the middle Holocene. Our study reveals similar asymmetric centennial-scale double-plunging structures of the 8.2 ka, 5.5 ka, and 2.8 ka events in the western CLP, suggesting a possible role of solar activity whose impact was amplified around 8.2 ka BP by the meltwater flood. In contrast, the 4.2 ka event exhibit gradually declining monsoon rainfall with centennial- to decadal-scale fluctuations.
