Abstract:The high quality of meteorological graphic products is important for the public meteorological service (PMS) in the time of media convergence. Based on the techniques of parallel computing and big data, message-driven making system of meteorological graphic products was developed, namely WeatherStudio. After analyzing the common problems of making graphical products for PMS, this paper discussed the advantages of the message-driven product making system, and then focused on the overall structure and main functions of WeatherStudio based on the message and timing driven techniques. Finally, the application of WeatherStudio in the expressway meteorological disaster risk early warning service shows its potential prospect.
