“…Therefore, we can draw the conclusion that the ORS developed in the warm-humid high sea level stages during the last interglacial period and in the relatively cold-dry low sea level stages during the last glacial period, but not occur in the lowest sea level stages during the LGM, the formation of the ORS was restricted jointly by climate changes of the source area and the distance from the shoreline that resulted from sea level changes. This result is consistent with previous studies that red dunes developed in high sea level stages and in relatively low sea level stages (Giannini et al, 2007;Tamura et al, 2011;Jayangondaperumal et al, 2012;Alappat et al, 2013). During the last interglacial period, under a warm-humid climate, the precipitation increased significantly, rivers transported sufficient sand supply to the coast, the intensified East Asian summer monsoon transported these sand materials and deposited along the coast.…”
