摘要
利用2001年1月至2010年12月内蒙古地区12个探空站的资料,求算全区空中水汽含量,对其时空分布特征及变化趋势进行分析。分析结果表明,近10a来,1月份内蒙古地区月平均空中水汽含量最低只有0.303cm;7月份月平均空中水汽含量最大达到3.106cm;空中水汽含量高值区在河套地区有西凸的倾向;空中水汽含量和降水量分布有正相关关系;逐年平均空中水汽含量处于缓慢的减少过程中。
Using the data of 12 sounding stations from Janury,2001 to December,2010 in Inner Mongolia,the atmospheric moisture content was calculated,and the spatial and temporal distribution characteristics and variation trend were analyzed,The results showed that the July monthly mean atmospheric moisture content reached the max value in last 10 years,which was 3.106 cm.The January monthly mean atmospheric moisture content reached the min value in last 10 years,which was 0.303 cm.The values of atmospheric moisture content over Hetao area were becoming higher.The correlation between atmospheric moisture content and precipitation was positive.It was also shown that the annual mean atmospheric moisture content was in a decrease variation trend.
