a Sr/Ca ratio from Datong core (this study), b, c Ri/b from G333 and Xiong’an-334 cores; d Sr/Ca ratio in carbonate nodule from Lingtai section36 - all indicating mid-latitude East Asia hydroclimate; e δ18O from Lop Nur core10 indicating mid-latitude Central Asia hydroclimate; f Smectite/Kaolinite ratio from ODP Site 114652 indicating low-latitude Southeast Asia hydroclimate; g–i Northern Hemisphere ice volume indicators: g global benthic δ18O stack49, h magnetic susceptibility from ODP Site 88247, and i diatom content from IODP Site U134048; j–l Modeled climate anomalies (PI_lgmseaice minus PIcntl): j Summer precipitation and 850-hPa wind field, k 108°E-110°E zonal wind (contours show PIcntl baseline), and (l) vertical velocity anomalies (positive/negative values indicate enhanced downward/upward motion, respectively). Site locations correspond to Fig. 1a annotations.
