This research proposed a kind of improved weather radar TITAN algorithm for different seasons,latitude and longitude and underlying surface in China.The weather radar data format conversion system is established in order to convert various Doppler weather radar base data in China to the MDV radar data format.The parameters threshold of radar characteristics of strong storm weather in different areas are counted based on different climate types,latitude and longitude and characteristics of land and sea.We make comparative experimental analysis between two typical weather radar base data of super-cell storm in Yunnan and Hainan regions and the improved weather radar TITAN algorithm.The results indicate that the error of using the improved TITAN algorithm to identify,track and predict strong storm weather after 30 minutes to 1 hour is relatively small,which has a higher credibility and could be conducive to identify disaster weather and commanding operation of weather modification.
