双线偏振雷达识别冰雹的数值研究

A Numeric Study of Hail Identification Using Dual-Polarization Radar

利用中国科学院大气物理研究所的三维冰雹云模式，详细地讨论了云雨衰减作用和云中各粒子共存于同一空间给双线偏振雷达识别冰雹带来的影响。在实际工作中，分析双线偏振雷达的回波时，这些讨论结果对分析和理解云降水过程有帮助。另外，本工作能为改装双线偏振雷达提供有益的理论参考。

Based on a 3D hailstorm model developes by the Institute of Atmospheric Physics, Chinese Academy of Sciences, how cloud attenuation and all particles coexist in the same space affect hail-iden- tification by using dual-polarization radar is discussed in detail. The results can help analyse echo of dual-polarization radar and understand process of cloud precipitation correctly. Furthermore, this work can give essentially theoretic references for remodeling dual-polarization radar.
