摘要
灾害性天气个例库智能分析系统是由基础数据支持子系统(数据层)、气象数据应用中间件子系统(服务层)和个例库综合分析业务子系统(应用层)3部分组成,综合运用HTML5 Canvas技术、数据库技术、GIS技术、高效可视化渲染技术等实现了气象灾害性天气个例的交互式录入、关键词查询与检索以及相关气象资料智能再分析等功能。文章针对系统的组成架构、个例库设计、功能特点等关键技术进行了重点探讨,并详细介绍个例库录入与查询、WebGIS组件、可视化渲染以及气象资料再分析等功能的设计和实现。系统投入业务运行结果表明,页面响应速度快、兼容浏览器性能佳、人机交互体验好,能够满足高效、智能、灵活的业务需求,在为预报员建立正确的预报思路、提升天气过程分析能力等方面发挥了重要作用。
Intelligent analysis system of a case base for disastrous weather includes three parts： basic data support subsystem （data layer）, meteorological data application middleware subsystem （service layer） and integrated analysis service of case base subsystem （application layer）. It can achieve the interactive input of meteorological disaster weather, query and retrieval of keywords, intelligent analysis of related meteorological data and other functions by comprehensively using various technologies in HTML5 Canvas, database, GIS, efficient visual rendering, etc. This paper mainly discusses the key technologies in the system architecture, design of case library and functional features, and instructs in detail the design and implementation of the functions such as data entry and query, WebGIS components, visual rendering, and reanalysis of meteorological data. The result operation application shows that the Web page responds quickly and has a good performance in compatible with browser and good human-computer interaction experience. It can meet the needs of high efficiency, intelligence and flexibility, playing an important role in the establishment of the correct forecast ideas and the ability to improve in the analysis of the weather process.
