| 摘 要： | 利用美国KOUN雷达的一次强对流天气过程的观测资料，讨论分析了利用双线偏振雷达观测资料识别冰雹区的方法，在此基础上建立了利用模糊逻辑法识别冰雹的识别模式，并对其得到的结果进行分析和讨论，为国内未来的双线偏振雷达业务运行提供参考和帮助。分析结果表明；基于模糊逻辑法利用双线偏振雷达观测资料建立的识别模式，不仅可以反映出实际的冰雹区位置，而且还可以对其分类。其识别的结果比较符合实际的天气过程。

| Abstract: | Based on the KOUN radar measurements, a classification model to identify the hail area and its application in operation are discussed. The results indicate that the model classifying result used dual-linear polarimetric radar observations is reasonable, it could retrieve not only the main shapes of realistic hails distribution but also the different types of hails, and the results have a good consistency with the true process of the terns. It is useful in operational works for the identification of hail areas and cation. convective sysweather modification. |
