Abstract:The development of global ocean forecasting models is closely related to the application of big data and meteorological forecasting models. This article briefly describes the application and characteristics of artificial intelligence technology based on deep learning in meteorological and ocean forecasting. The key report focuses on the research status of various scientific research institutions in China in the field of global ocean forecasting big models. The results indicate that current research in data-driven modeling, ocean big data analysis, and intelligent forecasting of ocean elements has reached a world leading level, with forecasting cycles and key prediction accuracy exceeding the current world"s advanced forecasting systems. Finally, based on the strategy of building a strong maritime nation, the challenges in the development of ocean intelligent forecasting in the field of equipment application were analyzed and discussed, as well as research directions for data processing and equipment application in the context of maritime security
