中文摘要：
利用GPS遥感的可降水量、气象数据、探空数据及降雪资料,分析中国北极黄河站区的可降水量特征,得出可降水量与地面水汽压的转换模型;分析可降水量、露点温度差、水汽压在强降雪天气中的变化特征,研究强降雪天气过程中的探空层结构,有助于利用GPS可降水量预报雨雪天气。
英文摘要：
The precipitable water vapor（PWV） reflects the total amount of water vapor of the atmosphere along the zenith direction, it is closely related to meteorological factors. The change of PWV shows a kind of regularity in the process of snowfall weather. Based on the consideration, a conversion model of PWV and ground water vapor pressure was established to analyze characteristics of PWV in Arctic Yellow River station of China with the data of GPS remote sensing PWV, meteorological data, sounding data and snowfall data. The results show that the PWV from GPS technique can be used to precast snowstorm process.
