Research And Implement Of Multi-mode Ensemble Visualization System For Space Weather Forecast

The project Space Weather Quantitative Forecast Technology and Ensemble committed by The National Satellite Meteorological Center is one of the programs from Special Fund for Meteorological Research in the Public Interest. The Center for Space Science and Applied Research Chinese Academy of Sciences participated in the project. The goal of the project is to construct a space weather quantitative operation forecast framework by bringing the intra-industry research potency together and transforming the domestic and overseas mature forecast research achievements into operational forecast technology. Based on the project, the article accomplishes an integrated visualized demonstration of space weather forecast modes and designs a high reusable and extensible multi-mode ensemble visualization software for space weather forecast.After study with the relative techniques such as solar-earth space environment, space weather forecast models, open software architecture and visualization technique, the article will be discuss with three problems: the design and realized method about space environment visualization system, visualization methods of space weather forecast models, implementation of system's human-computer interaction.Study with plug-in technique and make it to resolve the problems about reusability, extensibility, exchangeability, and construction of the ensemble system, our system enable to ensemble the visualization of most of the space weather forecast models. The article proposes a method of dividing the system into platform and plug-ins. The system developed by using Visual C++ programming technology and implemented the platform and plug-in framework of the multi-mode ensemble visualization demo system.After studying the visualization technique and analyzing the space weather elements and forecast models, the article discusses the techniques about utilizing OpenGL library and TeeChart component to fulfill the models visualization, and the techniques used in the visualization such as contouring algorithm and color mapped method in details.Based on the analysis of the mechanism and control method of 3D Scene roaming, a reusable and efficient human-computer interaction method is implemented in the system.According to the research of the project and the achievement of the system, it will provide experiences for future applying research and exploitation of space weather forecast models and space elements'visualization.
