摘要
为掌握称重式降水传感器的液态降水观测性能,推进降水自动化观测进程,按照降水过程强弱,依照北京市观象台2011年春夏季降水观测数据的统计结果,对DSH1型称重式降水传感器与业务用SL3-1型双翻斗雨量传感器进行比较分析。结果表明:以SL3-1型双翻斗雨量传感器为参照,DSH1型称重式降水传感器的观测数据基本可靠,在小雨过程中,两种型号传感器的观测数据有较好一致性;在中雨及大雨过程中,DSH1型称重式传感器与SL3-1型双翻斗雨量传感器还有一定的差异,有待于进一步试验与研究。试验过程中,DSH1型称重式传感器曾有故障出现,仪器可靠性有待提高。
To grasp the observability of weighing gauges for liquid precipitation and promote the automation of precipitation observation, a statistics analysis is carried out on the precipitation processes occurred in the spring and summer of 2011, and a comparison is conducted between DSH1 and SL3 1 sensors at Beijing Weather Observatory on the characteristics of precipitation dada. The results show that the data obtained from DSH1 are basically as reliable as SL3 1，and the differences of data between the two sensors are negligible during light rain processes, but cannot be neglected during moderate and heavy rain processes. Since failures of DSH1 were found out during use, the reliability of the instrument still needs to be improved.
