摘    要:利用地基GPS大气可降水量资料、常规气象资料和美国国家环境预报中心(National Cholesterol Education Program.NCEP)资料分析了2005年8月22-24日云南一次暴雨期间的水汽输送过程,分析了云南地基GPS立体布局的重要性.结果表明,GPS遥感的大气可降水量与探空观测结果有高度的一致性;地基GPS探测可以获得大气可降水量高频变化的信息;暴雨期间水汽输送主要集中在850~600 hPa之间的各层;立体布局的地基GPS网是监测西南水汽通道的有力手段.

关 键 词:地基GPS网  暴雨  水汽输送

Abstract:Based on the ground-based GPS Precipitable Water vapor (PW) data, weather stations' ground data and NCEP grid reanalysis dataset during the year 2005, the transfer process of water vapor during a summer rainstorm in Yunnan Province from August 22 to 24 in the year 2005 is studied, and the important role of the 3D distribution of the ground-based GPS net is analyzed. It is shown that the correlation between the PW from GPS and the PW from radiosondes is very good. The rapidly changing information of precipit...
Keywords:ground-based GPS net  rainstorm  transfer of water vapor
