Abstract：High precision rainfall monitoring and forecasting plays a supporting role for flood and drought disaster reduction by forecasting,early warning,rehearsal,and contingency plan.Rainfall radar systems mainly observe liquid water in the atmosphere within a height range of 2 km near the ground.It can achieve seamless and refined monitoring and generate high-precision,real-time and quantitative rainfall products.It has a relatively accurate ability to extrapolate rainfall forecasts for 1～3 hours and can be used as a typical model of new quality productive forces.The development process of rainfall monitoring in China has been systematically reviewed,including five stages of instrument free measurement,budding rain gauges,standardized artificial rain gauges,automatic recording rain gauges,and modern automatic rainfall measurement.According to the above,current status and issues with rainfall monitoring are analyzed.Based on review of development process of rainfall monitoring radar,its technical advantages are analyzed.The system can run stably and efficiently,to generate ultra fine grid rainfall real-time data in real time and achieve fine grid rainfall forecasting.Since the rain monitoring radar adopted in the Daqing River basin in Hebei Province and the Laodao River and Liuyang River basins in Hunan Province achieved good results,it shall be used as a new quality productive forces to empower the ability of forecast,early warning,rehearsal and contingency plan.
