The spatial-temporal patterns of East Asian climate in response to insolation, CO2 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 two stadials. Many simulations have been performed for the warmest MIS-5e period, but few has made to cover entire MIS-5 investigate variability during this long period. In study, sets snapshot a step 2 covering whole period are with model HadCM3 relative impacts insolation, CO2 Northern Hemisphere ice sheets on East Asian variability. Our results show that precipitation temperature in different subregions Asia sensitivity astronomical forcing, sheets, particular when seasonal mean annual changes concerned. The within mainly controlled precession their magnitudes modulated sheets. impact summer vary sensitive sheet configurations background insolation. southern China more than northern China. Moisture budget analysis insolation affect dynamic thermodynamic processes, respectively, through vertical processes which strongly associated sheet-induced wave train at hemisphere scale.
