The Design of Typhoon Meteorological Information System and its Implementation Based on WebGIS

This paper aims to introduce a marine and typhoon meteorological information system based on WebGIS and rich internet application(RIA), which integrate many kinds of data of typhoon and weather information according to a spatio-temporal model. The application based on such a system has been launched on the web with the URL http://typhoon.weather.com.cn/. This paper discusses the targets and design framework of the system, and analyzes the key problem of spatio-temporal model application in the system. Based on this typhoon information system, users can search every typhoon's information in Pacific costal region from 1949, such as monitoring data, forecast, satellite images, radar images, weather alerts, typhoon tracks, etc. The system has a lot of advantages compares to other similar systems, and it is fit for promotion as practical applications in other fields.
