两种不同新型气象雨量观测仪器的一致性对比分析
Comparison and Analysis of the Consistency of Two New Meteorological Rainfall Observation Instruments
摘要: 为验证DSG1型降水现象仪和DZZ4型自动气象站在测量降水方面的一致性，利用鲁南地区枣庄国家气象观测站2017年9月至2020年8月5年降水观测资料，对比分析了这两种新型气象雨量观测仪器测量降水的差异。研究结果表明：1) 这两种新型气象雨量观测仪器观测的降水时间基本相同，但DSG1型降水现象仪分钟、小时和日降水量均比DZZ4型自动气象站偏小；2) 在中等降水强度及以下，这两种新型气象雨量观测仪器观测的降水量大小基本一致，但降水强度较大时，降水量大小不同且分散；3) 这两种新型气象雨量观测仪器在地面降水观测业务中都有着比较良好的表现，由于仪器测量原理不同，DSG1型降水现象仪相对于DZZ4型自动气象站有更高的时间及空间分辨率，对于降水开始和结束时刻记录的更早更准确。
Abstract: In order to verify the consistency of DSG1 precipitation phenomenon instrument and DZZ4 automatic weather station in measuring precipitation, the precipitation observation data of Zaozhuang National Meteorological Observatory in southern Shandong from September 2017 to August 2020 were used to compare and analyze the differences between the two new meteorological precipitation observation instruments in measuring precipitation. The results show that: 1) The precipitation time observed by the two new meteorological rainfall observation instruments is basically the same, but the minute, hour and daily precipitation of the DSG1 precipitation phenomenon instrument is smaller than that of the DZZ4 automatic weather station; 2) At moderate precipitation intensity and below, the precipitation observed by the two new meteorological rainfall observation instruments is basically the same, but when the precipitation intensity is large, the precipitation is different and scattered; 3) The two new meteorological rainfall observation instruments have a relatively good performance in the ground precipitation observation business. Due to the different measuring principles of the instruments, the DSG1 precipitation phenomenon instrument has higher time and spatial resolution than the DZZ4 automatic weather station, and records the beginning and end of precipitation earlier and more accurately.
