全新世亚洲季风区和季风边缘区降水/有效湿度的古气候代用记录显示出时空不均匀性。利用基尔气候模式（KCM）对全新世9.5 ka BP至今（0 ka BP）的亚洲季风区和季风边缘区进行了一系列数值试验，研究了亚洲季风区和季风边缘区的空间差异和时间演变。模拟包括两个时间片的平衡实验，全新世早期（9.5 ka BP）和今天（0 ka BP），分别和一个瞬态模拟（HT）使用的方案，模型加速地球的轨道驱动的太阳辐射强迫的整个全新世时期（从9.5到0 ka BP）。在平衡试验中，模拟的夏季降水在季风亚洲地区表现出一种三极型，如H 0 K和H9 K的经验正交函数（EOF 1）的第一模态所描述的。瞬变模拟结果表明，亚洲夏季风系统对全新世轨道强迫太阳辐射变化的响应，使亚洲夏季风区夏季降水呈现出一种波列模式，并伴随着亚洲夏季风强度的逐渐减弱。多代用资料的综合和模式试验都证实了全新世东亚夏季风区、季风边缘区和西风主导区最佳降水/有效湿度的区域差异，表明区域气候系统对全新世太阳辐射变化的复杂响应与气候系统内部的反馈有关，如全新世亚洲夏季风演变中与厄尔尼诺/南方涛动（ENSO）和热带辐合带（ITCZ）移动有关的海气相互作用。
Paleoclimate proxy records of precipitation/effective moisture show spatial–temporal inhomogeneous over Asian monsoon and monsoon marginal regions during the Holocene. To investigate the spatial differences and diverging temporal evolution over monsoonal Asia and monsoon marginal regions, we conduct a series of numerical experiments with an atmosphere–ocean–sea ice coupled climate model, the Kiel Climate Model (KCM), for the period of Holocene from 9.5 ka BP to present (0 ka BP). The simulations include two time-slice equilibrium experiments for early Holocene (9.5 ka BP) and present-day (0 ka BP), respectively and one transient simulation (HT) using a scheme for model acceleration regarding to the Earth's orbitally driven insolation forcing for the whole period of Holocene (from 9.5 to 0 ka BP). The simulated summer precipitation in the equilibrium experiments shows a tripole pattern over monsoonal Asia as depicted by the first modes of empirical orthogonal function (EOF1) of H0K and H9K. The transient simulation HT exhibits a wave train pattern in the summer precipitation across the Asian monsoon region associated with a gradually decreased trend in the strength of Asian summer monsoon, as a result of the response of Asian summer monsoon system to the Holocene orbitally-forced insolation change. Both the synthesis of multi-proxy records and model experiments confirm the regional dissimilarity of the Holocene optimum precipitation/effective moisture over the East Asian summer monsoon region, monsoon marginal region, and the westerly-dominated areas, suggesting the complex response of the regional climate systems to Holocene insolation change in association with the internal feedbacks within climate system, such as the air-sea interactions associated with the El Nino/Southern Oscillation (ENSO) and shift of the Intertropical Convergence Zone (ITCZ) in the evolution of Asian summer monsoon during the Holocene.
