中文摘要	利用美国宇航局(NASA)发布的2003年1月~ 2015年12月的AIRS Standard Physical Retrieval Edition 6. 0中的level2的反演数据,对新疆及其周边地区特别是三大山区近13 a的可降水量的时空分布特征进行了研究。结果表明,从空间分布看,可降水量高值区主要集中在盆地地区,尤其在塔里木盆地、准噶尔盆地及吐鲁番盆地。低值区主要分布在新疆南部的昆仑山脉和北部的阿尔泰山脉。最高值达14. 74 mm,最低值达1. 92 mm;新疆及其周边地区可降水量所有格点13 a平均值来看,总体上,夏季最高,冬季最低。从时间分布看,对新疆及其周边地区、天山、昆仑山和阿尔泰山4个研究区域分别进行区域平均,发现以上4个区域年变化呈单峰型,从1 ~ 7月的可降水量逐渐增加,8 ~ 12月份的可降水量逐月减少;可降水量的整体年际变化趋势是一致的,2003 2010年呈上升趋势,20102015年呈下降趋势。
英文摘要	Xinjiang is located in a arid region of northwest China,with dry climate, strong evaporation,and an overall shortage of water resources. Therefore,water resources play a decisive role in the sustainable development in Xinjiang. The total precipitable water vapor (TPWV in short) is the material basis for the formation of clouds and precipitation and an important part of water resources. Although previous studies on the spatial and temporal distribution of TPWV have yielded a lot of results, the research using AIRS data for water resources utilization and precipitation predicting in Xinjiang is still insufficient. In this study, the temporal and spatial characteristics of TPWV in Xinjiang were analyzed using the AIRS Standard Physical Retrieval Edition 6. 0, level 2 inversion data from January 2003 to December 2015 released by NASA. The results are as follows: (1) The amount of TPWV was decreased from the basins to the mountains. The high value areas were located mainly in Junggar Basin,Turpan Basin and Tarim Basin. The maximum of TPWV occurred in Turpan Basin, reaching 14. 74 mm. The low value areas were located mainly in Kunlun Mountains,Tianshan Mountains and Altay Mountains. The minimum of TPWV occurred in Kunlun Mountains, reaching 1. 92 mm. The distribution of TPWV in Turpan Basin and Junggar Basin showed a decreasing trend from west to east with four levels. The distribution of TPWV in Tarim Basin showed a decreasing trend from west to east with three levels. The spatial distribution of TPWV in the above three mountains was gradually decreased from the piedmont fringes to the top of the mountain,and the areas in the mountains near basins had a relatively higher values of TPWV compared with other areas of the mountains. The maximum of TPWV in Xinjiang occurred in summer, followed by autumn and spring. And in winter, there was the minimum TPWV. The maximums of TPWV in summer and autumn appeared in Turpan Basin,which were 26. 4 mm and 14. 11 mm respectively. The maximums of TPWV in winter and spring appeared in Tarim Basin and Junggar Basin,which were 6. 75 mm and 13. 69 mm respectively. The difference in the amount of TPWV in each area was the smallest in winter, followed by spring and autumn,and the largest in summer. (2) The annual variation of TPWV in Xinjiang and its surrounding areas,Tianshan Mountains,Kunlun Mountains and Altay Mountains was of a single peak type. From January to July, the amount of TPWV was gradually increased,and the amount of TPWV from August to December was decreased month by month. Xinjiang and its surrounding areas,Tianshan Mountains,and Altay Mountains had their peaks in July,which were 16. 45 mm, 19. 09 mm and 16. 27 mm respectively,while Kunlun Mountains had its peak in August, reaching 13. 24 mm. The minimums of TPWV appeared in Xinjiang and its surrounding areas,Tianshan Mountains,Altay Mountains and Kunlun Mountains in January,which were 2. 84 mm,3 . 06 mm,2 . 37 mm and 2. 16 mm respectively. (3) The inter-annual variations of TPWV in Xinjiang and its surrounding areas,Tianshan Mountains,Kunlun Mountains,and Altay Mountains were consistent, showing an upward trend from 2003 to 2010 and a downward trend from 2010 to 2015. Xinjiang and its surrounding areas,Tianshan Mountains and Kunlun Mountains had their peaks in 2010,which were 8. 92 mm,10. 47 mm,and 7. 07 mm respectively,while Altay Mountains had its peak in 2008, reaching 8. 26 mm. The minimums of TPWV appeared in Xinjiang and its surrounding areas,Tianshan Mountains,Kunlun Mountains and Altay Mountains in 2015,which were 7. 37 mm,8. 81 mm, 5. 13 mm and 6. 81 mm respectively.
