Abstract By using the 1100×1100 longitude-latitude grid data of Jiangxi WebGIS radar composition,based on the recursive algorithm,the target on the identification of the powerful echo is achieved,the strong weather area can be judged and the early warning information is extracted. This paper provides the analysis data about strong weather such as position,intensity,area,which is the basis of short-term prediction and early warning service for strong weather.
