Abstract: 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.

Key words: forecast workstation, data communication, data compression
