Application of Graphic and Image Technology in Strong Convective Weather Monitoring and Early-Warning System

Abstract

In order to improve the capability of monitoring and predicting strong convective weather of Zhaoqing area, monitoring and early-warning system of strong convective weather is developed. Graphic and image technology is applied in the development of the system. The region growing method is used in image segmentation. The map of all towns of Zhaoqing area is drawn by coordinate transformation and graphics technologies. The processed radar image and the map of Zhaoqing area have been overlapped. By using improved arc-length method, the system can judge which areas are affected by strong convective echo.
