湖北地基GPS大气可降水量变化特征分析及应用
Analysis and application of ground-based GPS precipitable water vapor characteristics
摘要
Abstract
In order to analyze the spatial and temporal distribution of water vapor in Hubei province,the ground-based GPS atmospheric Precipitable Water Vapor (GPS/PWV) at Enshi,Yichang and Wuhan site were compared with the radiosounde data(RS/PWV) and found that the GPS/PWV has a good consistency with RS/PWV.The three-year GPS/PWV analysis of 17 stations shows that the GPS/PWV has significant monthly and daily variation features,and its distribution diminishes gradually from the south to the north,but increases gradually from the west to the east in Hubei province.A case analysis on heavy precipitation illustrates that the peak value of GPS/PWV appears slighdy earlier than that of precipitation and radar echo intensity.GPS/PWV with high spatial and temporal resolution combined with radar is conducive to the overall analysis of the synoptic situation and precipitation information.关键词
