| 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.

| 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... |
