Abstract: This study investigated characteristics of extreme precipitation,atmospheric circulation and its relationship around the Qinghai Lake region in recent 60 years in order to provide evidence to understand variation of water resource in Qinghai-Tibetan plateau.In this paper,spatial and temporal variation of extreme precipitation was analyzed in details based on daily precipitation data from meteorological stations using liner trend analysis method.Precipitation of summer half year,extreme precipitation index increased significantly in recent 60 years around the Qinghai Lake region,especially since 2005.Abrupt change has happened in precipitation in the early 21st century,and most extreme precipitation index in summer half year had abrupt changes in this period.The Antarctic Oscillation Index（AAO） and the Western Pacific Subtropical High Intensity Index（WPSH）led to an obvious abrupt changes on extreme precipitation and significantly positively correlated with extreme precipitation index.There was a short cycle of 6 years and a long cycle about 16 years in summer half year precipitation and extreme precipitation around the Qinghai Lake region.The increasing trends of extreme precipitation and extreme precipitation days in summer half year are more significant in the west than in the east around the Qinghai Lake region.
