| 摘 要： | 对塔里木盆地夏季降水过程和复杂的大气水分循环结构进行了分析，采用常规气象观测、探空及其不同网格NCEP等再分析数据，通过塔里木盆地视热源、水汽汇、涡度、散度三维动力结构以及相关小波周期分析、水汽输送通道相关矢量场及其Fluxpart轨迹模型等各类方法，综合剖析该区域大气热源与夏季降水过程及其水分循环结构特征。计算分析结果表明塔里木盆地沙漠边界层辐射强日变化叠加上周边C型大地形“山谷风”效应，导致高山环抱盆地及沙漠区的独特水、热过程与局地环流特征。

| Abstract: | Surrounded with the Tibetan Plateau and Tianshan Mountains, the Taklimakan desert, known as the ＆quot;sea of death＆quot;, is located in the Tarim basin, one of the largest inland basins in China. In the Taklimakan desert, precipitation plays a critical role in formation, maintenance and recovery of ecosystems. Under the impact of westerlies and monsoon, there is a unique water cycle over the Tarim Basin of arid region in northwest China. By using the data of surface and sounding observations and NCEP-reanalysis data, this paper comprehensively analyzed the processes of summertime precipitation and water cycle over the Tarim Basin with apparent heat source and moisture sink, vorticity, divergence, wavelet cycle, correlation vector of vapor transport flux and Fluxpart trajectory model. The analysis found that the integrated influences of distinct diurnal variation of surface radiation in the Taklimakan desert and forcing of＆quot;mountain valley breeze＆quot; built by the large terrain background in the surroundings of Tarim Basin lead to the unique water and heat cycles and diurnal change of local circulation in the atmosphere over the desert basin. |
