The ncep / ncar global reanalysis data about 55 yean ; ( 1948 - 2002 ) , the observed data about 2 years ( 1999 - 2000 ) , the meiyu data in the mid - lower reaches of the yangtze river and the precipitation data at 160 stations in china duing 1951 to 2000 are used in the paper . we present a preliminary study on the relationship between the precipitation total for meiyu and the summerly precipitation in the eastern side of the northwest china . then using nonhydrostatic version mm5 with one nested grid , the effect of the circulation patterns for meiyu on the summerly precipitation in the eastern side of the northwest china was simulated by numerical simulation of full physics 本文采用1948 2002年ncep再分析資料、 1999 2000年的全球地面、高空觀測資料、 1951 2000年梅雨以及全國降水量資料,初步研究了長江中、下游地區梅雨事件與西北地區東部夏季降水的聯系,并用mm5中尺度非靜力模式模擬了多(少)梅雨環流型對西北東部夏季降水的影響;另外,還分析了梅雨與四川盆地、東南沿海地區夏季降水的聯系。
