中文摘要	利用最靠近库姆塔格沙漠的4个气象站点1960-2014年的逐日降水数据和2008-2014年中国自动气象站与CMORPH融合逐时降水量0.1°网格数据集,对库姆塔格沙漠年降水、年大降水和月降水、月大降水的年际变化分别做了对比分析,在此基础上运用中国自动气象站与CMORPH融合逐时降水量0.1°网格数据集对库姆塔格沙漠平均月降水和大降水的空间分布进行了分析.结果表明,库姆塔格沙漠大降水主要集中在夏季,夏季大降水量占年总大降水量的80%.库姆塔格沙漠各月降水类型以午后型为主,大降水类型以凌晨型和黄昏型为主.库姆塔格沙漠及周边地区平均月降水量和大降水量的空间分布一致,一年中平均月降水量和大降水量最大值均出现在6月.春季、秋季和冬季,库姆塔格沙漠南缘阿尔金山存在一条呈东西向分布的降水量大值带;夏季,阿尔金山降水量大值带基本消失.
英文摘要	Based on daily precipitation data from 1960 to 2014 and the Chinese automatic meteorological station and CMORPH- fusioned hourly rainfall of 0.1° grid data set from 2008 to 2014,the inter-annual and monthly variability of precipitation and heavy precipitation in the Kumtag Desert were analyzed. The mean monthly precipitation and heavy precipitation were analyzed on account of the Chinese automatic meteorological station and CMORPH- fusioned hourly rainfall of 0.1° grid data set, with the results that heavy precipitation in the Kumtag Desert were mainly concentrated in summer, and the percentage of heavy precipitation in summer to annual total heavy precipitation was 80%. The pattern of monthly precipitation thereof was ’the afternoon’, while the patterns of monthly heavy precipitation were ’the early morning’ and ’the afternoon’. The distribution of precipitation in the Kumtag Desert and its surrounding areas was in agreement with the distribution of heavy precipitation; the maximum and heavy precipitation occurred in June. A belt of precipitation existed in the south of the Kumtag Desert around the Altun Mountains in spring, autumn and winter while, in summer, the belt almost disappeared.
