Research Abstract |
Reconstructed provenances of eolian dust in Japan Sea sediments exhibit millennial-scale variations during MIS 1 and 5, which we interpret to reflect changes in the timing of the seasonal northward movement of the westerly jet axis. The westerly jet changes probably cause millennial-scale changes for the latitudinal distribution of the East Asian Summer Monsoon precipitation. The coupled changes represent climate instability in East Asia during past warm periods.
