Based on the observation data of Binhai and Lvsi stations in the past ten years, this paper analyzes the temporal and spatial distribution characteristics and formation conditions of sea fog along the coast of Jiangsu Province, and obtains some rules, such as: winter and spring are the seasons of frequent sea fog along the coast of Jiangsu Province, when the relative humidity is≥85%, the temperature difference between water and air is within plus or minus 8°C, when the southeast wind is easier to form fog, and the wind speed generally does not exceed 5 levels. In addition, the sea fog in Jiangsu coastal area can be generally divided into inverted trough type, low pressure type, cold air type and high pressure type, and it is easy to form fog when inverted trough. Continuous multi-day sea fog is often the continuous influence of various weather situations. All these provide ideas for the prediction of sea fog in Jiangsu coastal area.
