To investigate 28 the spatial differences and diverging temporal evolution over monsoonal Asia and monsoon marginal 29 regions, we conduct a series of numerical experiments with an atmosphere-ocean-sea ice coupled 30 climate model, the Kiel Climate Model (KCM), for the period of Holocene from 9.5 ka BP to present (0 31 ka BP). The simulations include two time-slice equilibrium experiments for early Holocene (9.5 ka BP) 32 and present-day (0 ka BP), respectively and one transient simulation (HT) using a scheme for model 33 acceleration regarding to the Earth's orbitally driven insolation forcing for the whole period of Holocene 34 (from 9.5 to 0 ka BP).
