中文摘要: 作者介绍了在一次强雹暴系统的雷达探测中发现的阵风锋回波带。讨论了阵风锋回波带的性质、结构及其成因，分析了它对雹暴回波系统的反馈作用，指出了其和经典模式中阵风锋的不同之处。提出了这次雹暴系统维持和传播的自激机制，并且探讨了阵风锋回波带在短时预报中的应用。

Abstract:The band echo of the gust front of a severe hail storm system is found out during radardetection of the hail storm. The properties )structure and causes of the band echo of the gustfront are discussed. The reactions of the band echo of the gust front on the hail storm systemare analyzed. The band echo of the gust front is different from that of the gust in a classicalmodel. The self-trigger mechanism for continuation and conveyance of the hail storm systemis given. Application of the band echo of the gust front to nowcasting is considered tentatively.
