Integration of space weather modes is the basis of operational space weather forecasting. The software system of visualization demo in integration of space weather modes is one of the significant research issues. There are a great deal of space weather modes with diverse elements and complex models, and there are differences in modes’ visualization forms and methods. Combined with characters of current space weather modes in China, the article constructs a multi-mode ensemble visualization demo system with good compatibility and high extensibility, which integrates visualization for most of the current space weather modes. A method of spatial data management is proposed. Based on the OpenGL and Visual C++ software platform, the system fundamentally implements the visualization integration of space weather modes by dynamic loading.
