| 摘 要： | 利用2007年12月成都地基GPS网络观测数据反演的大气可降水量和地面自动气象站网观测资料,分析了对成都市交通和环境造成严重影响的7次大雾天气过程。通过对有雾和无雾时GPS可降水量、地面空气比湿的合成分析,从雾区上空和近地层水汽变化分析了四川盆地辐射雾形成的原因,而GPS可降水量的日变化特征可为大雾天气的短时临近预警预报提供有价值的参考信息。

| Abstract: | In this paper,the precipitable water vapor derived from GPS(GPS PWV) was investigated based on the observation experiment of ground-based GPS network and automatic weather stations in the Chengdu area in December 2007.By using the GPS PWV data,seven fog processes causing serious traffic and environmental impact over the Chengdu area were analyzed.The integrated analysis of diurnal cycles of the GPS PWV and specific humidity were carried out according to coses with and without fog.The causes of the radiation... |
