区域自动站小时降水量质量控制方法的研究

Quality Control Method for Hourly Rainfall Data of Regional Automatic Weather Station

通过多部雷达拼图经纬度网格点资料,利用雷达Z-R关系对宜春市256个区域自动观测站小时降水量资料进行了计算和统计分析,得出了不同条件下Z-R关系中A和b这两个参数的合理取值,并对256个区域自动观测站小时降水量资料进行了质量控制方法的研究,实现了对256个区域自动站小时降水资料质量控制的实时短信报警工作。

Based on longitude-lantitude grid data of several weather radars with echo mosaic,Z-R relation of radar was used to calculate and statistically analyze the collected hourly rainfall data of 256 regional automatic weather stations in Yichun city. Reasonable values of A and b parameters in Z-R relation under different conditions were obtained. In addition,after investigation of quality control method for hourly rainfall data of the 256 regional automatic weather stations,hourly real-time SMS alarm work with quality control of the rainfall data was realized in these stations.
