中文摘要	利用巴州加密自动站观测资料对塔克拉玛干沙漠东部边缘测站进行统计分析,查找该地区降雨的日变化特征,得出其东北部边缘和东南部边缘在降水频次与量级以及降水时段上有不同,其东北部边缘地区的降水高值区主要出现在凌晨3∶00、早晨的8∶00~9∶00、午后的17∶00,且午后17∶00达到高峰值;低值区为早上的7∶00和18∶00以后至翌日凌晨1∶00;其东南部边缘地区的降水高值区主要出现在早上8∶00,降水低值区出现在14∶00。各测站降雨量级主导频次均为小雨频次,最小频次均为暴雨频次,降雨的最大贡献者除若羌为中雨量级外,其它测站均为小雨量级,轮台、且末、铁干里克的中雨为最小贡献者,库尔勒最小贡献者为大雨量级,若羌和尉犁为暴雨量级。
英文摘要	Using the meteorological data of Bayingolin Mongol Autonomous Prefecture,Xinjiang,China observed by automatic weather stations on the eastern margin of the Taklimakan Desert,this paper made a statistical analysis to find the daily variation characteristics of the rainfall in this region. Results show that there are differences of precipitation frequency,precipitation magnitude and precipitation period between northeast margin and southeast margin. High precipitation on the northeastern margin of Taklimakan Desert mainly occurred at 3∶00,8∶00-9∶00 and 17∶00,and reached the peak at 17∶00,while low precipitation occurred at 7∶00 and from 18∶00 to 1∶00 of the next day. High precipitation on the southeastern margin of the Taklimakan Desert mainly occurred at 8∶00,and the low precipitation occurred at 14∶00. The rainfall frequency on the eastern margin of the Taklimakan Desert is dominated by light rain,storm had the minimum frequency. According to the contribution rate of rainfall,light rain had the biggest contribution to rainfall in Korla,Luntai,Qiemo and Tieganlike,moderate rain had the biggest contribution to rainfall in Ruoqiang,moderate rain had the minimum contribution to rainfall in Luntai,Qiemo and Tieganlike,heavy rain had the minimum contribution to rainfall in Korla,and rainstorm had the minimum contribution in Ruoqiang and Yuli.
