| 摘 要： | 利用最新云南地基GPS站观测和探空观测资料分析表明:GPS/PWV和探空大气可降水量变化趋势一致,相关性好;云南省GPS/PWV年内干湿季气候特征分明,湿季开始前GPS/PWV月变率小于干季开始前的月变率;全省GPS/PWV年平均日变化峰值和谷值出现时间一致,勐腊、蒙自和昆明具有准双峰型特征;勐腊站干季、湿季日变化明显不同,其余测站干季和湿季的PWV日变化特征与全年平均日变化特征基本一致。GPS/PWV资料能够反应云南雨季开始期时空演变趋势。

| Abstract: | Using newest Yunnan ground GPS-retrieved atmospheric Precipatable Water Vapor(PWV)with the meteorological sounding observation to be analyzed,the results shown that GPS/PWV has the consistent change tendency and good correlation with the radiosonde observation.The GPS/PWV in Yunnan Province has distinct climate characteristics of dry season and rainy season within the year,starts,GPS/PWV monthly variation rate before the beginning of the rainy season is smaller than of the dry season.The peak to volley valu... |
