Description :
This study concerns 2 sites in the desert-loess transition belt of Central China. High-resolution paleomonsoon proxy records from peat and eolian sand-paleosol sequences at the desert-loess transition zone in China denote a rapid oscillation from cold-dry conditions to cool-humid conditions, followed by a return to cold-dry climate. The inferred precipitation variations were likely caused by variations in the strength of the Siberian high, which influenced the pressure gradient between land and ocean and therefore influenced the position of the East Asian monsoon front.
