| 摘 要： | 本文针对武汉地区GPS气象网资料,进行了GPS对流层延迟直接推算可降水量的研究。在武汉东湖站GPS对流层延迟与无线电探空可降水量的比较中,两者具有很好的相关性,相关系数达到了0.93;推导了对流层延迟直接推算可降水量的模型,对模型结果进行了检验,在武汉东湖站的对流层延迟转换的可降水量与无线电探空可降水量的比较中,均方根为7.8mm,相关性为0.91,这说明了在没有气象数据的地区对流层延迟直接推算的可降水量可以作为气象短期预报的参考。

| Abstract: | With the data of GPS meteorology network in Wuhan region, the article discussed the study of directly calculating precipitable water vapor with GPS zenith tropospheric delay. In the comparison of radiosonde precipitable water vapor and GPS zenith tropospheric delay in Donghu of Wuhan, there is a good relativity and the correlative coefficient is 0.93. It deducted the model of directly calculating precipitable water vapor and proof-tested the model. The root mean square of GPS precipitable water vapor and radiosonde is 7.8mm and the correlative coefficient is 0.91 in the comparison between the precipitable water vapor of zenith tropospheric delay and radiosonde data. It was illuminated that the precipitable water vapor of zenith tropospheric delay can be considered as the reference of short-forecast of meteorology in the none meteorology data region. |
