一种格点预报数据分布式服务系统的设计与实现
|
摘要
对气象业务中数值预报的数据特点和使用现状进行研究和分析,提出一种数值预报数据在气象业务应用中的分布式数据服务方法。解决在分布式存储环境下,高时效地对种类繁多的海量数值预报科学数据进行存储管理、写入、读取和计算的集中处理问题。详细描述海量数值预报数据的存储组织方式,分布式的数据服务方法,高可用性的实现方式以及各种格点数据的处理方法。业务应用表明,系统在广东区域格点化预报的业务应用中满足高效、稳定和使用便捷的要求。
This paper studied and analyzed the data characteristics and application status of the numerical prediction in meteorological service,and presented a distributed data service method for the application of the numerical prediction data in the meteorological service. The method solved the centralized processing problem of storage management,writing,reading and computing for a wide variety of massive numerical prediction scientific data in a distributed storage environment. This paper described the storage organization,the distributed data service method,the high availability method and the processing methods of various grid data. The application shows that the system meets the requirements of efficient,stable and convenient use in the application of Guangdong regional grid prediction.
