Abstract: The presented research is a part of the PMIP project (Palaeoclimate Modelling Intercomparison Project) concerning the comparison between the observatory evidence and modelling experiments. The simulated objective is the global moisture condition at 6 000 yr. BP The purpose of the simulation is to verify the changes in insulation exerting the influences on the large-scale climatic systems. The observations we used are lake status records which were reconst ructed from the vario us geologic evidence. In fact, the lake level change reflects the variation of moisture conditions, particularly the effective precipitation (precipitation minus evaporation) within the lake basin. The results show that all the experiments can reproduce the wetter conditions in African and Asian monsoon areas, therefore, confirming the hypothesis of that the enhancement of Afro-Asian monsoon were induced by the seasonal change of solar radiation. But all experiments are fail to produce a broader and moreintense monsoon enhancement compared with the geologic records. The cause maybe associated with the "modern" treatment of surface coverage and thermal properties. Most experiments are incapable to model the shifts of westerlies in mid-latitudes induced by the change of insulation. Most experiments also fail to reproduce the moisture conditions from the areas where are profoundly influenced by the oceanic currents and sea surface temperature, which is likely to be related with the absence of oceanic function in the models.
