结合713型雷达数据，探讨了基于GIS技术和雷达数据的人工降雨预警方法．通过雷达数据分析云系中的含水量、云系强度，通过多幅天气雷达数据判断云的走向和速度，并制定跟踪路线，结合地面炮点位置确定人工降雨作业的最佳时机和用弹量．以MapX作为GIS2次开发工具，实现了可以实时判断人工降雨条件的平台，实施效果良好．

Study on methods for acquisition of radar echoes and judgment on artificial rainfall operating sites based on GIS

Based on the parsing of 713 radar data format, this paper researches the methods of simulated rainfall warning system combining GIS technology and radar data. Cloud water content and cloud intensity are determined through radar data analysis and these data can be used to judge whether it should start warning system or not according to the warning threshold values. It can determine the direction and speed of clouds moving through several radar maps and then obtain a follow-up line indicating the clouds moving direction. Combined with the judgment of rain-making artillery positions, it can determine the best time and amount of shelling for operation. This paper uses MapX5. 0 as GIS secondary development tool to achieve the simulated rainfall warning system which can be used as a platform for making a real-time judgment on the conditions of the artificial rainfall operation with good effect.
