Abstract: Aimed at the problems of serious jam for the network transmission of large-scale global high-resolution meteorological grid data and front-end real-time rendering visualization, a meteorological grid data visualization system based on CUDA is designed. The system was based on the uni-app framework. Through the integration of data slicing, CUDA data parallel processing, data compression, multi-threaded data transmission between Web and server, front-end color mapping visualization and other technologies, it could better realize the super fast visualization of high-resolution meteorological data in the front-end, as well as the cross platform one-click migration and deployment of the system.
