长江三角洲气象数据实时共享技术研究与实现

Real-Time Sharing Technology of Meteorological Data in Yangtze-River Area and Its Implementation

通过基于数据超市理念的气象数据实时共享技术研究,首次建成上海、浙江、江苏、安徽三省一市间互联互通的长江三角洲(长三角)气象数据实时共享平台。该平台设计并使用标准规范体系,建立基于分布式的数据管理模式,采用多层系统架构,实现物理上分布、逻辑上统一的长三角区域气象数据资源组织与共享。能有效支持短临天气预报对实时数据的高时效要求,支持灾害性天气移动观测、加密观测业务的数据共享,提高气象数据实时共享效率,降低数据更新分发的难度。

Based on the researches on the real-time sharing technology of meteorological data,which uses the concept of data market,a meteorological data sharing platform for Yangtze-river area between Shanghai,Zhejiang,Jiangsu and Anhui provinces is first built.The platform is designed by the standard system and distributed data management model,which makes use of the multi-layer system architecture. The sharing and organization of meteorological data show unification in both physical distribution and logical inference.The platform can effectively support weather nowcasting for real-time data and mobile observation.It also can improve the efficiency of meteorological data sharing in real time and reduce the difficulty of data transfer.
