半干旱地区大气水汽含量反演分析

Retrieval Analysis of Atmospheric Water Vapor in Semiarid Region

利用SACOL站2006年7月至2007年4月的CE-318型太阳光度计晴空日观测资料及同期降水资料,研究了半干旱地区大气水汽含量及降水转化率,结果表明:半干旱地区大气水汽含量夏季最高,秋季次之,冬春季最小;四季典型晴空日大气水汽含量变化为夏季最剧烈,秋季次之,冬、春季最小;夏、冬季具有人工增雨(雪)的潜力,7月、8月、12月、2月进行人工增雨(雪)最为适宜,合理开发云水资源对后期及次年的农业生产和生活有很大影响。

Based on the clear sky observation data and precipitation data of CE-318 sun photometer between July,2006 and April,2007 ,the atmospheric water vapor content and the precipitation conversion of semiarid region were studied.The results showed that the highest atmospheric water vapor content was in summer ,the second was autumn ,winter and spring were minimal.The day of atmopsheric water vapor content changed in the four seasons：the most violent was summer, the second was autumn, the winter and spring were minimal.The spring and winter had the potential of artificial precipitation （snow） enhancement, the best time of artificial precipitation （snow） enhancement were July, Auguest, December and February, rational development of cloud water resources had great effect on late and the following year agricuhural production and living.
