Based on the daily precipitation data of 122 stations in Northeast China(NEC),the NCEP/NCAR reanalysis data and the monthly temperature data of 160 stations from NCC(National Climate Center) during 1961-2010,this paper reveals the rainfall patterns of NEC in June,July and August and analyzes the characteristics of abnormal atmospheric circulation.Results indicate that the precipitation of NEC can be divided into the consistent rainfall pattern(more rainfall pattern or less rainfall pattern) and the south-north anti-phase rainfall pattern(southern rainfall pattern or northern rainfall pattern) in June and August,and the consistent rainfall pattern(more rainfall pattern or less rainfall pattern) and the east-west anti-phase rainfall pattern(eastern rainfall pattern or western rainfall pattern) in July.In addition,the precipitation of NEC in June is related to Northeast cold vortex(the stronger cold vortex,the more rainfall),and the south-north anti-phase rainfall pattern is affected by the abnormal Okhotsk blocking high.The precipitation of NEC in July and August is related to East Asian summer monsoon,and the consistent rainfall pattern is affected by both the location of western Pacific subtropical high and the the wave train propagating eastward along the upper westerly jet stream,while the south-north(east-west) anti-phase rainfall pattern is affected by the intensity of western Pacific subtropical high.
