在本系列的第二部分中，概述了极化雷达观测的应用。这包括数据质量改进的总结，以及对暖季和冷季降水观测的特征和算法输出的解释。业务产品的示例包括水凝物分类、冰雹检测和分级以及定量降水估算。审查的特征包括在强对流风暴和超级单体中发现的特征，例如微分反射率 (ZDR) 柱、ZDR 弧和龙卷碎片。还讨论了融化层亮带、雪晶识别和生长区域以及冷季风暴中降水类型的转变。重点是我们的知识现状，以及正在进行和未来的研究主题，这些主题为业务气象学带来了有希望的好处。
In this second part of the series, an overview of applications of polarimetric radar observations is given. This includes a summary of improvements to data quality, and interpretation of signatures and output of algorithms for observations made in warmand cold-season precipitation. Examples of operational products include hydrometeor classification, hail detection and sizing, and quantitative precipitation estimation. Signatures reviewed include those found in severe convective storms and supercells such as differential reflectivity (ZDR) columns, ZDR arcs, and tornadic debris. The melting layer bright band, snow crystal identification and growth regions, and transition of precipitation type in cold-season storms also are discussed. The emphasis is on the current state of our knowledge, as well as ongoing and future research topics that offer promising benefits to operational meteorology.
