In recent years, the demand for mobile meteorological services has grown rapidly, and the auxiliary decisionmaking function of meteorological information has become more and more prominent in modern meteorological service systems. How to quickly establish a reliable, easy-to-expand, autonomous, and controllable mobile weather service system has become the core concern of meteorological departments at all levels. This paper introduces the overall design of building a refined mobile meteorological service system based on the Hybrid mode and realizes the display and interaction of meteorological information on mobile terminals through Hybrid, component-based development, MVC framework, HTML5 fusion and other key technologies. It embodies the technical advantages of the Hybrid development mode in the aspects of high function reuse and convenient iteration and upgrades. After iteratively upgrading for nearly five years, the system products have been widely applied in the meteorological departments, governments, and key industries at all levels in Shandong Province. It has played an essential role in meteorological services for social disaster prevention, mitigation and relief.
