| 摘 要： | 利用美国ＮＣＥＰ／ＮＣＡＲ全球网格点再分析资料，从大气环流角度系统地分析了１９７９～１９９５年夏季（６～８月）新疆出现降水偏多或偏少时北半球范围内平流层下部（１００ｈｐａ）和对流层中部（５００ｈｐａ）的平均环流形势。结果表明新疆夏季降水偏多或偏少同期具有各自较为显著的环流特征；最后选取１９９６年夏季和１９９８年夏季两个典型个例加以补充说明。

| Abstract: | The average circulation situations in lower stratosphere(100hPa) and middle troposphere(500hPa) in the Northern Hemisphere are analysed by using reanalysis data on global grids from NCEP/NCAR of USA when rain is more or less than normal one in Xinjiang in summer.It turns out that the departure of summer rain corresponds to a certain of circulation patter.Two examples of summer rain in 1996 and 1998 are given to demostrate. |
