Based on WebGIS, HTTP communication, and database technologies, the drawbacks of the existing weather warning system are studied. A unified communication protocol is designed, and a oneclick integrated management and releasing platform of weather warning information is developed. The platform enables WebGIS map display, weather data overlay, and the oneclick dissemination, publication and distribution of early warning information. The oneclick publishing technology opens a new approach to the enhancement of meteorological service and warning information publishing capabilities.
