英文摘要	Mineral dust exerts great influence on modern climate. Eolian deposits reveal that atmospheric dust concentration is larger during the Last Glacial Maximum, especially over Asia. However, the larger forcing of dust on Asian climate is still not fully explored. In this study, climate model experiments are conducted to evaluate the direct radiative effect on East Asian monsoon. The results show that the radiative forcing of dust, amplified by snow albedo feedback over high-latitude Eurasia, produces a wave-like pattern in westerlies and weakens the monsoon southerly winds over northern China. Dust over expanded Last Glacial Maximum sources (northern Central Asia and northeastern Russia) is responsible for this perturbation of the westerlies; the absence of these dust sources at present explains why such impacts on circulations are not simulated for modern conditions. The dust-induced anomalies in southerly wind speed and precipitation over northern China reach 29% and 41% of the glacial-induced changes, respectively.
