Implementation and Development Plan of MICAPS4
-
摘要: 以精细化预报为标志的现代天气预报业务对高时空分辨率气象数据的应用提出了更高的需求，而传统的预报分析制作系统MICAPS3（Meteorological Information Comprehensive Analysis and Processing System Version 3）无法满足符合大数据特征的实时预报相关的数据应用。同时，模式预报和集合预报应用已在各专业预报领域中发挥越来越重要的作用，网格预报产品正在涵盖全部的预报业务流程，而MICAPS3无法提供便捷高效的支撑。为解决上述问题，国家气象中心启动了MICAPS4建设，一方面建立了基于大数据的气象实时预报应用技术体系，解决了气象大数据处理、存储、分析和显示效率的关键技术难题；另一方面搭建了多个满足不同复杂预报业务需求的专业化版本。MICAPS4将信息化技术与预报技术、预报业务流程紧密结合，解决了现代化预报方法的平台化集成应用与精细化预报制作的关键技术难题，基于MICAPS4基础框架的多个专业版在中央气象台和部分省级气象台进行业务化应用推广。基于CIMISS（China Integrated Meteorological Information Sharing System）-MICAPS4的海量数据存储环境，极大减轻了系统部署和本地化工作量，显著提升了数据解析及数据存储访问效率。

Abstract: Marked by refined weather forecasts, modern weather forecasting demands for higher spatial and temporal resolution of weather data applications. However, the existing forecast analysis system-MICAPS3 (Meteorological Information Comprehensive Analysis and Processing System Version 3) cannot meet needs of using real-time meteorological data with big data characteristics. Besides, MICAPS3 cannot provide sufficient support for numerical weather prediction model, ensemble prediction model and grid forecasting product, which are playing increasingly important role in the professional forecasting fields. Therefore, China National Meteorological Center launches development of MICAPS4, aiming to build an advanced, efficient, intelligent, convenient and open modern weather service forecast platform.Firstly, established a real-time forecasting system based on big data technology to solve the key technical problems of data processing, storage, analysis and display efficiency. Secondly, set up several specialized platforms to meet needs of different complex forecasting business. MICAPS4 combines information technology with forecasting technology and forecasting business processes to solve the key technical problems of the platform integration of modern forecasting methods and the production of refined forecast, many of specialized platforms based on MICAPS4 basic framework have promoted the application of business in China National Meteorological Center and many provinces. CIMISS (China Integrated Meteorological Information Sharing System)-MICAPS4 massive data storage environment has greatly reduced the workload of system deployment and localization, improved data analysis and data storage access efficiency significantly. Besides the utilization of the big data technology, MICAPS4 client is also upgraded in underlying rendering engine using parallel computing framework, and it can display high resolution data in high efficiency including the stream animation as a result. MICAPS4 client follows the OGC (open geospatial consortium) standards, to achieve the standard of geographic information and the intervention of WMTS (Web map tile service). The client of MICAPS4 allows users to customize data display style conveniently and support the forecast product rapid manufacturing. Flat design interface is adopted and users can switch between black theme and white theme quickly, to reduce visual fatigue and support the forecast product rapid manufacturing.MICAPS4 is a modern full-purpose forecaster work station system for processing and displaying meteorological data. The multi-window technology and specialized applications make MICAPS the ideal tool not only for operational weather forecasting, but also for other applications where meteorological information plays a vital role. -
