The monsoon region of the eastern part of China and the arid region of western part of China are the sensitive areas of global change, which are separately controlled by monsoon and westerly circulation.In the past 50years, due to global warming, the precipitation of the arid region of Northwest China has significantly increased while the precipitation of the monsoon region of the eastern part of China shows no obvious variation.The future trend of two regional precipitations remains uncertain under the conditions of continuous global warming.Based on the speleothem growth rate records from Sanbao Cave, Shennong jia, Hubei, and Kesang Cave, Tekesi County, Xinjiang, we investigate the responses of those records to precipitation and the precipitation variations as well as distinctions of the two regions on glacial-interglacial scale, providing a case for precipitation forecasts from climatic models in future warming in China.It is found that the precipitation of the eastern part of China and the northwestern part of China fluctuate during glaciation-interglaciation, with an abundant precipitation in both two regions during interglacial period, corresponding to higher temperatures.Nevertheless, the precipitation of Northwest China lags behind that of the eastern part of China, implying the correlation between precipitation and temperature of the two regions are probably not completely simultaneous.
