摘要: 应用GPS探测的可降水水汽资料Pwv对上海地区2002~2005年强对流的水汽变化特征进行了分析。分析表明:每30分钟一次的GPS/Pwv资料能直观地、及时地反映大气中水汽的时间变化和空间变化;GPS/Pwv资料随时间的演变特征与降水有较好的对Abstract: Based on the Precipitable Water Vapor(PWV) data from GPS,the water vapor variation characteristics of severe convection in Shanghai from 2002 to 2005 was analyzed.The result showed that the GPS/PWV data of every
