| 摘 要： | 利用2000-2009年南昌、赣州两个探空站资料,通过计算大气水汽含量和水汽通量,对江西省空中水汽含量变化、分布、水汽输送等特征进行了分析。结果表明,近10年来,江西省平均大气水汽含量为35.04 kg/m2,水汽含量呈下降趋势。水汽含量夏季丰富,冬季匮乏,2-6月是江西大气中水汽含量主要增长期,最大值出现在8月,最小出现在1月或12月;空间上呈现南多北少分布。水汽输送在春、冬季以纬向输送为主,夏、秋季经向和纬向输送量基本相当。

| Abstract: | Using 2000—2009 sounding data of Nanchang and Ganzhou,by calculating the vapor content and vapor flux,the distribution and variation of vapor content and the characteristic of vapor transportation in Jiangxi are analyzed.The results show that the vapor content of Jiangxi decreased during the past 10 years and the average value was 35.04 kg/m2,which was rich in summer and shortage in winter,more in south and less in north.The maximum vapor content appear in August,the minimum occurr in January or December.The vapor transportation is mainly zonal in the spring and winter. |

| Keywords: | Vapor content Vapor transportation Variation Jiangxi |
