利用雨量雷达构建面雨量自动监测系统

雨量雷达是专门适用于气象目标中降雨量定量测量的雷达设备,高分辨区域面雨量自动监测系统则是应用雨量雷达进行区域内雨量监测,监测系统通过雨滴谱仪与模型算法解决衰减订正和雨量数据计算准确度问题,可以方便地获得区域内的降雨分布情况和有效的降雨量,与常规单点雨量定量测量相比,在较大区域内测量雨量,整体上精度高,成本低。经过大理监测区域的验证,面雨量自动监测系统具备较高的测量精确度,具有较好应用前景。

An automatic monitoring system of area rainfall based on rain radar

The rain radar is a kind of specific equipment suitable for rainfall quantity measurement in meteorology subject. The automatic monitoring system for the fine grid precipitation applies the rain radar to area rainfall monitoring . That monitoring system solves attenuation correcting and rainfall data quality control by means of laser drops spectrometer and real-time attenuation model and inversion algorithm. It can obtain area rainfall distribution and effective rainfall data. Compared with regular single rainfall measurement, that monitoring system has the advantage of high entirety accuracy with low cost in large area. The monitoring system has high measurement accuracy and good application future after being proved by field test at Dali,Yunnan.
