| 摘 要： | 利用NCEP/NCAR再分析资料和气象中心站点资料对华北地区水汽含量与降水量的分布特征进行了分析.结果表明:华北地区水汽含量和降水量的分布规律一致,即夏季水汽含量高降水量大,冬季水汽含量低降水量小;降水量的分布不仅受水汽含量的影响同时也受到水汽输送的影响;多年来华北地区水汽含量和降水量均呈减少的趋势,水汽含量的减少是降水量减少的主要原因.

| Abstract: | The distribution characteristics of water vapor content and precipitation in North China are analyzed by using NCEP / NCAR reanalysis data and information from China Meteorological Center.The analysis result shows that the water vapor content and precipitation in North China are in the same distribution.The water vapor content is higher in summer than in winter and the precipitation is greater in summer than in winter.Not only the water vapor content but also the water vapor transport affects the distributi... |
