Insolation and CO2 impacts on the spatial differences of the MISâ€9 and MISâ€11 climate between monsoonal China and central Asia
On the Chinese Loess Plateau, the development of the paleosol S3 that was formed during the MIS-9 interglacial is weaker than some other paleosol units such as the S4 soil that was formed during the MIS-11 interglacial, suggesting relatively drier climate condition during MIS-9. By contrast, in Taji...

On the Chinese Loess Plateau, the development of the paleosol S3 that was formed during the MIS-9 interglacial is weaker than some other paleosol units such as the S4 soil that was formed during the MIS-11 interglacial, suggesting relatively drier climate condition during MIS-9. By contrast, in Tajikistan of southern central Asia, the S3 is the most developed soil over the past 800 ka, indicating relatively warm and humid climate conditions. The difference in the paleosol formation and the MIS-9 climate between monsoonal China and central Asia is intriguing. In this study, we combine loess records from monsoonal China and central Asia as well as climate simulation results to understand the spatial difference of the MIS-9 climate in particular in comparison with the climate of MIS-11. Our results show that under the combined effects of greenhouse gases (GHGs) and insolation, the simulated effective moisture conditions between northern China and southern central Asia are consistent with the loess records.
