摘要: 随着我国多普勒天气雷达网建设的深入发展, 雷达气象产品系统开发和资料应用越来越迫切。文章介绍了开放软件系统模型, 分析了新一代天气雷达特点和发展需求。结合新一代天气雷达网和我国气象业务网发展状况, 提出和研究了可供新一代天气雷达使用的开放系统的分布式业务模式, 研究和设计了雷达气象产品开放系统的结构和运行方式。文中的分布式开放型雷达产品系统的结构和模型, 对其他类业务和科研系统的开发和发展具有参考价值。Abstract: China Doppler weather radar (CINRAD) network consisting of 158 radars with S and C bands is being built. Radar meteorological products exploitation and data applications are getting more and more imminent and necessary with the development of CINRAD; meanwhile, NEXRAD open system plan is being implemented. So the CINRAD operational model and product system infrastructure are key and important issues.CINRAD characteristics and development requirements are analyzed, and an open model of operational application system and data distribution for CINRAD is presented. The CINRAD has 6 type radars with S and C band made by 3 factories, so it is needed that very good interfaces for different scan patterns, data formats, and excellent development and test environment for different algorithms, and integrative processing and display system for different wave bands and many kinds of observation data. CINARD has lots of users on weather forecast, weather modification, hydrometeorology and traffic management etc, so it is necessary that software update and continuous developments of algorithms, and it is required that open and distribution structures. In terms of China meteorological operation model and CINRAD status, it is advanced that distribution products operations model and base data transport scheme. And it is also designed that the intrastructure and operating mechanism of open product system for CINARD.The existing NEXRAD ORPG is an open and loosely-coupled system, it supports other systems and algorithms to be operating together by parallel interfaces, and the Linear-Buffer supports separate modules data communication, so that CINRAD Radar Product Generator (CRPG) is designed as a compatible system with ORPG. The OPRG, CRPG and their low-level interface libraries are encapsulated with a new control interface which connected by Radar Data Acquirement (RDA) and Meteorological Information Comprehensive Analysis and Process System (MICAPS). The open and distribution radar product scheme is helpful to other meteorological software systems of China.
