摘要
提出了一种利用常规质量控制方法、空间水平一致性和雷达组合反射率强度与降水强度阈值判定的综合性质量控制方法,对对逐小时降水异常站点进行识别。通过个例分析表明:该分析方法可有效查找出小时降水数据中的异常数据,在提高质量控制、分析系统时效的基础上,缩短了雨量传感器故障发现时限,为降水过程中的设备维护提供了合理的数据证据,增强了装备保障的时效性。
This paper presents an integrated quality control method for hour precipitation data by using threshold detection to conventional meteorological data, analyzes the spatial coherence and the relationship between the weather radar composite reflectivity and the precipitation intensity. By means of individual case analysis, it shows that this method can find out the abnormal hour precipitation data. This combined quality control method not only improve the efficiency of precipitation data quality control,but also shorten the found time for fault sensor. Using this method provides the evidence of reasonable data in precipitation equipment maintenance and strengthens the effectiveness of meteorological equipment maintenance.
