摘　　要：海量高频度的天气雷达资料获取、处理及快速显示分析是短时天气预报中非常重要的环节。该文从系统需求、设计和实现等方面描述开发一个完整的短时预警报服务系统的方法。介绍通信系统设计、图像工作站的开发和数据压缩技术等的应用。通过自主开发的GIS系统,解决了图像动画和对准问题,运用多线程调度满足海量资料的实时分析要求。实际应用表明,系统具有很强的实时性,可以满足业务上的需求。The large-scale weather radar data obtaining, processing and quickly display analysis is very important in nowcasting warning. This paper gives a method to study nowcasting warning system from the system requirement, design and realization. It introduces the design of communication system and workstation, and use of data compression technique. It uses the geographic information system to solve the problem of image animation and registration, and uses multi-threading method to solve real analysis requirement in large-scale process. Experimental results show that the system is very good in real time. It can satisfy the need of business.
