气象综合指挥平台建设与应用北大核心CSCD

在重大活动、突发气象灾害以及汛期会商服务等特定时空气象保障过程中,采用各单位逐一汇报及展示专业产品或系统等传统方式,形成的产品及系统深度专业,但无法互动且运行协同不足,影响实时保障服务效益。气象综合指挥平台充分利用现有气象业务数字化成果,面向气象保障服务的时空及可视化需求,采用混合存储、接口服务以及图层组件发布等技术,实现多源数据的标准化处理、功能集约建设以及图层渲染等组件松耦合发布,首次在气象保障服务中接入空间天气、风云四号气象卫星高分辨率数据、秒级观测以及百米融合实况等数据及产品,实现气象产品全在线服务与中国气象局电视会商、云会商系统音视频信号的同步实时调度,为实时气象保障调度指挥提供服务支撑。该平台集成113种气象产品,发布1106个图层服务,成功完成2022年北京冬奥会和冬残奥会等国家重大气象保障工作,未来可为各类气象保障系统开发及专题气象保障服务提供支撑应用。

Construction and Application of Meteorological Integrated Command Platform

Meteorological support is demanded during major events, sudden meteorological disasters and flood season consultation services. In traditional way, each department reports and displays the products one by one, which limits operational coordination, interaction and the benefits of real-time support. To improve the service, an integrated command platform for meteorology is built by adopting technologies such as hybrid storage, interface service and layer component release. The platform couples standardized processing of multi-source data, integrated construction of functions, layer rendering and other components loosely. It is based on the meteorological big data cloud platform of China Meteorological Administration, releasing meteorological products such as satellite, radar measurements, real-time and intelligent forecasts. A hybrid integrated application framework is developed for traditional structured data storage, geographic information spatial storage, index storage (Elasticsearch) and page cache storage (Redis), and provides efficient retrieval services. At the same time, the transmission component integrates high and low 8-bit compression and concurrent transmission technology of multiple domain name to improve efficiency. In the aspect of page interaction and visualization, based on NPM (package management tool of JavaScript language), Vue components, WebGL visualization and other front-end technologies, a component-based encapsulation and application service mode is constructed, which gives full play to the high collaboration between cloud computing and edge computing of server and client (browser), supports fast data switching and navigation between different meteorological elements at any geographic location, and provides support for unified access, dispatching and command of multi-source data in various meteorological support services. At present, the platform integrates 113 meteorological products and 1106 layer services, effectively supporting major national meteorological support services such as 2022 Beijing Winter Olympic Games and Winter Paralympic Games.
