Design and Application of a Weather Forecasting and Early Warning Service System for Yangtze River Shipping

For the visual meteorological support services of Yangtze River shipping, in this paper, the Weather Navigation Grade is designed to represent the influence of weather on shipping, and the algorithm of the Weather Navigation Grade under two service scenarios is given, using the weather monitoring, grid forecast and service warning along the Yangtze River, applied to calculate the shipping dispatching management and ship schedule planning. The method of applying the Weather Navigation Grade to intelligent navigation meteorological service is described. This paper introduces the overall design, main products, system functions and main characteristics of the Yangtze River shipping meteorological forecast and early warning service system based on the Weather Navigation Grade, combined with the development of shipping meteorological service, and the future improvement direction of the system is discussed.
