This paper categorizes the features shown in Doppler radar products both on the echo intensity and on the moving velocity fields of severe convective systems,such as gale,hail,tornado,etc.,which occur within the scanning range of new generation Doppler weather radar of Changde station,and demonstrates by examples that characteristics displayed in Doppler radar products of severe convective weather in America are similar to counterparts in China,moreover,it supplements other elaborate features. According to these,the technique adapted to local forecasting of severe convective weather and based on sigle Doppler radar products is constructed. Furthermore,by using real-time radar volume-scanning data,it practicably discusses the aspects of both the audio and literal auto-warning of severe convective weather and the moving path and speed prediction of storm. Finally,during the exploring and developing stage of the application of Doppler radar products,this technique provides a systematic idea for forecasting severe convective weather in China.
