摘要 美国国家气象局 (NWS) 于 1991 年 3 月在俄克拉荷马州诺曼开始使用天气监视雷达 1988 多普勒 (WSR-88D) 系统。 WSR-88D 数据已提供给另外五个办事处的预报员：佛罗里达州墨尔本和弗吉尼亚州斯特林（自 1992 年 1 月起）；密苏里州圣路易斯和堪萨斯州道奇城（自 1992 年 3 月起）；和德克萨斯州休斯顿（自 1992 年 4 月起）。对 WSR-88D 投入使用前后六个办事处的严重局部风暴和山洪预警计划的性能进行了定量测量。定量评估中使用的验证程序和统计方法是国家气象局实际使用的程序和统计方法。统计数据显示，WSR-88D 运行时，警告显着改善。具体来说，恶劣天气事件的发现概率增加，误报数量减少。所有严重的当地风暴和山洪的交货时间也显着改善......
Abstract The National Weather Service (NWS) began operational use of the Weather Surveillance Radar-1988 Doppler (WSR-88D) system in March 1991 at Norman, Oklahoma. WSR-88D data have been available to forecasters at five additional offices: Melbourne, Florida, and sterling, Virginia (since January 1992); St. Louis, Missouri, and Dodge City, Kansas (since March 1992); and Houston, Texas (since April 1992). The performance of the severe local storm and flash flood warning programs at the six offices before and after the availability of the WSR-88D was measured quantitatively. The verification procedures and statistical measures used in the quantitative evaluation were those used operationally by the NWS. The statistics show that the warnings improved dramatically when the WSR-88D was in operation. Specifically, the probability of detection of severe weather events increased and the number of false alarms decreased. There was also a marked improvement in the lead time for all severe local storm and flash flo...
