| 摘 要： | 将地面观测的降水划分为10～25、25～50、50～100mm/h3个量级区间,利用2010年5-10月天气雷达组网小时降水量产品和综合气象观测系统运行监控平台(ASOM)中国家级台站自动气象站小时降水量资料,采用3倍标准差法,按上述3个等级逐月分别确立了两类设备降水观测差值的阈值参数,进而建立了天气雷达与地面自动气象站降水观测结果的一致性实时校验技术.采用该技术进一步对2011年5-10月国家级台站自动气象站观测的降水结果进行了检验,结果表明:自动站降水数据正确率可达85％以上,可以有效进行自动站观测降水实时检验.

| Abstract: | The ground precipitation is divided into 3 intervals (10 to 25, 25 to 50, and 50 to 100 mm/h), and with the hourly precipitation measurements from weather radar and national surface observation automatic weather stations from ASOM from May to October in 2010, using three time standard deviation method, the threshold parameters of precipitation observation differences for two kind of equipment are determined month by month, and a real time rainfall calibration technique between weather radar and automatic weather stations is devised. Using this method, the accuracy of rainfall between May and October 2011 is tested. The results show that the correct rate of the rainfall is greater than 85% after using this new method, which means that this method is effectible in testing the surface precipitation measurements from automatic weather stations in real time. |
