| Abstract: | Through the real-time analysis of Doppler radar PUP data, including Echo Tops （ ET ） , Radar Reflectivity （R19）,and Vertically Integrated Liquid （VIL） water content,ArcGIS Identify tool is programmed, which will get data collection from raster feature generated by radar data.We propose the concepts of warning radius and warning region attached angle θ,design monitoring point sampling algorithm,azimuth algorithm,（θ,α） point selection algorithm and identify algorithm,furthermore,complete the simulations of each algorithm based on C#.Fi-nally,the automatic warning system prototype was accomplished in Visual Studio 2008,which can generate real-time operating parameters of each operating point. The research provides necessary theoretical and technical support for intelligent operation of weather modification. |
