Abstract: In order to improve the ability of the hydro-meteorological service, the hydro-meteorological service system of Hanjiang Basin in southern Shaanxi was established based on the refined weather forecast technology and hydro-meteorological model as well as related meteorological observations and hydrological information. The system was designed and developed according to the developing of automatic hydro-meteorological monitoring network, refined hydro-meteorology forecast, as well as the preliminary application of hydro-meteorological service and exploring of 3D simulation. Meanwhile, an ‘ABC’ technology including “artificial intelligence”, “big data” and “cloud computing” had been put into use in the system. As a result, the system could provide the refined forecast and service products and the scientific emergency strategies for the weather monitoring and forecasting, the meteorological service in flood prevention, especially the flood prevention scheduling in Hanjiang Basing in southern Shaanxi.
