The operational platform of weather forecast for Changzhou is devised with Visual Basic 6.0 language along with Microsoft FrontPage, Microsoft Access, Java, Photoshop, etc. It uses the climatic data of Changzhou Station from 1952 to 2003. The synoptic models are revised by the empirical indexes based on the knowledge of wellexperienced forecasters, and the working flow is standardized based on the Project 9210 and available interconnected network systems. The application of the system shows that the platform is very convenient to search, analyze, produce and distribute all kinds of meteorological information, allowing humancomputer interaction.
