The spatial-temporal patterns of East Asian climate in response to insolation, CO 2 and ice sheets during MIS-5
Marine Isotope Stage (MIS) 5, between about 130 and 70 ka BP, is characterized by climate oscillations consisting of three interstadials and two stadials. Many climate simulations have been performed for the warmest MIS-5e period, but few has been made to cover the entire MIS-5 to investigate the cl...

Marine Isotope Stage (MIS) 5, between about 130 and 70 ka BP, is characterized by climate oscillations consisting of three interstadials and two stadials.

In this study, two sets of snapshot simulations by a step of 2 ka covering the whole MIS-5 period are performed with the model HadCM3 to investigate the relative impacts of insolation, CO 2 and Northern Hemisphere ice sheets on the East Asian climate variability. Our results show that precipitation and temperature in different subregions in East Asia have different sensitivity to astronomical forcing, CO 2 and ice sheets, in particular when seasonal and mean annual changes are concerned.
