Abstract: In recent years, China's marine meteorological numerical prediction has achieved some progress. National-level cities and coastal provinces have established a number of sea-fog, wave, storm-tide-ranging marine meteorological numerical prediction models. Through the investigation of marine meteorological numerical prediction models in China's coastal provinces and their application, this paper summarizes the development status of the Chinese marine meteorological numerical prediction model, analyses the existing marine meteorological numerical prediction problems and challenges, and discusses the future development and suggestion of marine meteorological numerical prediction.
