广西城市空气污染预报业务系统的建立

应用数值预报与动态统计预报相结合的集成预报技术方法，将城市大气污染数值预报(CAPPS)模式、动态统计模式、Sybase数据库、网页技术等有机地结合起来，建立广西城市空气污染预报系统，形成了流畅的集资料传输交换、预报模式运算、预报制作与发布于一体的气象系统和环保系统预报会商的综合业务工作平台，在广西气象台同时对南宁、桂林和北海的城市空气污染做出预报。将近两年的业务实践应用表明，所建立的空气污染预报系统性能稳定、技术成熟、自动化程度和预报准确率高．

Establishment of City Air Pollution Prediction System in Guangxi

The city air pollution prediction system in Guangxi was established by applying component prediction technology of the numerical prediction model and the model of dynamic statistics prediction. Also, the platform for the workers from the departments of meteorology and environment protection to hold consultations on city air pollution prediction was set up. The feature of the air pollution prediction system was that the model operation of air pollution prediction, the data transmission and exchange, the outcome of prediction were integrated with, and the Guangxi Meteorological Observatory could issue air pollution prediction at the same time for the cities of Nanning, Guilin and Beihai. The practice in prediction for two years indicated that the system performed stably, automatically and accurately.
