摘要
针对武汉地区GPS气象网进行了3方面的应用研究。首先为利用武汉地区的无线电探空资料推算了适合武汉地区的大气加权平均温度计算模型,该模型与Bevis模型存在一定的区别;其次为武汉地区GPS气象网的可降水量的可靠性研究,将GPS可降水量与无线电探空数据比较,得到两者差值的均方根为3.9 mm,相关系数为0.933。最后为武汉地区GPS气象网的可降水量序列对武汉地区2005年入秋季节的转换进行了监测,得到武汉地区的入秋转换为2005年262日14时开始,263日11时完成。
There are three applications to the GPS Meteorology Network in Wuhan Region. Firstly it is the computation of the model of the weighted mean temperature of the atmosphere in Wuhan Region with the radiosonde data of Wuhan, which is different from the model of Bevis. Then the article deducts the reliable research of precipitable water vapor of the GPS Meteorology Network in Wuhan Region. With the comparison of GPS precipitable water vapor and the data of radiosonde, the root mean square is 3.9 mm and the correlative coefficient is 0.933. In the end it is the utilization of monitoring the conversion of autumn in Wuhan Region with the GPS precipitable water vapor, which the beginning of the conversion of autumn in Wuhan Region was 14th hour in 262 day and ending in lPh hour, 263 day.
