摘要
高分辨率面雨量雷达测雨系统是应用低空雨量雷达进行区域雨量监测,通过雨滴谱仪进行衰减订正后,获取区域内降雨分布和有效的降雨量。通过2台低空雷达组网的左江上游面雨量雷达测雨系统将左江上游平而河和水口河区域概化分为16个区,每小时自动分析、计算、处理16个区域有效面降雨量后,通过开展与相邻的传统雨量监测站数据对比分析,并与广西洪水预报系统衔接开展预警预报的应用,为今后高分辨率面雨量雷达测雨系统在广西的进一步有效应用打下基础。
The high-resolution areal rainfall radar rain measurement system is to use low altitude rainfall radar for regional precipitation monitoring.Regional rainfall distribution and effective precipitation were acquired after attenuation correction was carried out with raindrop spectrometer.For the upper reach of Zuojiang River,the areal rainfall radar rain measurement system consisting of two sets of low altitude radars are adopted;Pinger River and Shuikou River are divided into 16 zones;hourly automatic analysis,calculation and processing of effective areal rainfall data of 16 zones are conducted.The measuring data are compared with the monitoring data out of adjacent traditional rainfall stations,and are connected to the Guangxi flood forecast center for prediction purpose,which lay foundation for further effective application of high-resolution areal rainfall radar rain measurement system in Guangxi.
