为了测试偏振雷达产品在作战环境中的实用性和附加值，将俄克拉荷马州诺曼（KOUN）偏振天气监测雷达1988多普勒（WSR-88D）的数据作为联合偏振实验（JPOLE）的一部分交付给位于诺曼的美国国家气象局天气预报办公室（WFO）。WFO在强对流、山洪和冬季风暴的决策和预报过程中使用了KOUN极化基础数据和算法。交付包括常规WSR-88D雷达产品、基本极化雷达变量、极化水流星分类算法和实验性极化定量降水估计算法。描述了JPOLE数据的收集、交付和操作演示，并举例说明了几个预测和预警决策的成功。偏光数据帮助世界气象组织预报了几段大雨、大量产生大冰雹的雷电……
Abstract To test the utility and added value of polarimetric radar products in an operational environment, data from the Norman, Oklahoma (KOUN), polarimetric Weather Surveillance Radar-1988 Doppler (WSR-88D) were delivered to the National Weather Service Weather Forecast Office (WFO) in Norman as part of the Joint Polarization Experiment (JPOLE). KOUN polarimetric base data and algorithms were used at the WFO during the decision-making and forecasting processes for severe convection, flash floods, and winter storms. The delivery included conventional WSR-88D radar products, base polarimetric radar variables, a polarimetric hydrometeor classification algorithm, and experimental polarimetric quantitative precipitation estimation algorithms. The JPOLE data collection, delivery, and operational demonstration are described, with examples of several forecast and warning decision-making successes. Polarimetric data aided WFO forecasters during several periods of heavy rain, numerous large-hail-producing thunder...
