本文通过对2025年春季发生在浙江丽水一次冰雹过程的不同波段雷达监测资料分析，Zdr、Kdp等偏振量能够较好地反映出这次过程的风暴内部冰雹的发展过程；这些偏振量的应用能够有效识别冰雹的发生发展过程，有利于及时预警；S波段雷达适合系统整体监测和追踪，X波段雷达在近雷达处和低层的精细结构分析上更有优势，2种雷达具有明显的互补价值。
Abstract：Through the analysis of multi-band radar observations during a hailstorm event in Lishui, Zhejiang Province in spring 2025, polarimetric parameters such as Zdr and Kdp effectively revealed the internal development of hailstones within the storm system. The application of these polarimetric variables significantly improved hail detection and early warning capabilities. S-band radar demonstrated advantages in large-scale monitoring and storm tracking, while X-band radar provided superior resolution for fine-scale structural analysis at lower altitudes and closer ranges. The two radar systems exhibited strong complementary value in hail observation.
