摘　　要：本文利用多普勒天气雷达(CINRAD/SA)及常规资料,对2004年5月22日发生在江苏东北部的一次阵风锋天气现象进行了详细分析。阐述了阵风锋的反射率因子和多普勒径向速度特征,如回波强度、宽度、成因及冷锋过境前后的速度场特征等。并且探讨了阵风锋在短时预报中的应用。In the paper a detailed analysis is made by using CINRAD/SA Doppler weather radar and conventional observation data on a gust front process which occurred on 22 May 2004 in the northeast of Jiangsu province. The features of reflectivity and radial velocity of gust front, such as intensity, width, formation mechanism and radial velocity before and after cold front passing through the territory, are analyzed. The application of gust front to nowcasting is also considered.
