A traffic meteorological service system based on mobile internet is designed. Through combining a series of refined gridded data, the system provides a series of personalized traffic meteorological services based on locations, such as voice navigation services for highimpact weather, meteorological knowledge extraction, integrated Web publishing based on WebGIS, and intelligent navigation based on the refined gridded data. To ensure high bearing capacity and rapid response characteristics, the refined gridded data are transferred in the binary model, and the tiled map resources are generated in the distributed computing environment. The whole process of data processing is managed by the memory management mechanism of Memcached. This system has already been applied as an independent module in the SmartWeather mobile client designed by the Zhejiang Provincial Meteorological Service.
