With the rapid development of information technology and the rapid advance of meteorological modernization, the public demands for meteorological services are getting higher and higher. Meanwhile, the types and quality of meteorological service products also need to keep pace with the times. Starting from the actual needs of users, this article studies the service phrase algorithm and application of 0 to 1 hour precipitation forecast, which is based on the data fusion of radar inversion, focusing on the implementation of 0 to 1 hour precipitation forecast algorithm design and the algorithm logic of service phrase generation under different precipitation trends. On the basis of the research results, the 0 to 1 hour precipitation forecast service phrase application system is developed, which has been integrated into the smart meteorological APP and the Zhejiang precipitation distribution system client software to carry out mobile services. It not only opens up a new model of networking weather service and helps to improve the quality of meteorological service, but also lays a foundation for the future researches and application of various kinds of meteorological service phrases.
