摘要
文章参考国家级观测站人工观测降水记录,对两个区域站降水现象仪数据的完整性、准确性、降水现象起止时间等方面进行分析评估。此外,本次还结合了湖州本地的雷达回波图像,大致判断区域站降水的出现情况和起止时间,并对两种比较方法的结果进行对比。两种对比方法的结论出现较大差异,造成差异的主要原因是降水的局地特征非常明显,不能单纯地将附近站点的人工数据作为参考标准,必须引入当地的雷达回波图像作为参考。
Based on the manual observation of precipitation records at the national observatory,this paper analyzes and evaluates the completeness and accuracy of the precipitation data and the start and end of precipitation phenomena of two regional stations.In addition,the local radar echo images in Huzhou is also used as a reference to roughly determine the occurrence of regional precipitation and starting and ending time,as well comparing the results of two comparison methods.The conclusions of the two comparison methods are quite different,because there are obvious differences in the local characteristics of precipitation.So only the reference of data from the nearby sites is not enough,the local radar echo image must also be considered.
