Short summary
Multiscale signals were decomposed from Chinese loess and speleothem records over the last 260 kyr. We found great glacial and orbital impacts on the loess grain size changes and dominant precession forcing in the speleothem δ18O variability. The millennial components are evident in the loess and speleothem proxies with variances of 13 and 17%. Close matches of millennial monsoon events between these two proxies indicate similar driving force linked to high-latitude Northern Hemisphere climate.
