中文摘要: 利用河北省石家庄、张家口、秦皇岛3个GPS站观测资料,通过GAMIT软件处理反演到2005年4
—11月的大气可降水量(PWV)资料,初步分析了河北大气可降水量时空分布特征。结果表明
,GPS反演的大气可降水量具有较高的使用价值,其时空变化明显,反映了河北降水的季节
和地区变化特征。通过与降水之间关系分析发现,降水大多出现在高于大气可降水量基值的
时段,不同影响天气系统, 大气可降水量变化具有不同的变化特征。
Abstract:The space time distribution features of the atmospheric precipitable wa
ter vapor over the Hebei province are preliminarily analyzed using the GPS data
of Shijiazhuang, Zhangjiakou and Qinhuangdao from Apr. to Nov. 2005, which were
processed b
y GAMIT software .It indicates that the precipitable water changes remarkably
with seasons and precipitation mostly occurs in the period when precipitable w
ater is larger than its threshold value. It also suggested that different variat
ion characteristics are correspondent to the different weather systems.
