Abstract: A review of the research progress over the past few decades is presented here on the sea fog forecasting technique based upon statistical and numerical prediction. The statistical method is a major tool except the synoptic method on the sea fog forecast at coastal meteorological observatories in China. It improves the forecasts of sea fog but have defects of the empirical statistics. With the rapidly development of computer technology, the numerical simulation and prediction on sea fog events are applied widely and will become the main method. Nowadays, the sea fog numerical prediction models are developed from the one-dimensional to three-dimensional and from the single atmospheric model to coupled air-sea model. The advanced assimilation technique, which assimilates the satellite data to overcome the lack of marine observations, together with the ensemble prediction in the three-dimensional numerical prediction model, which uses a higher resolution, selects the most suitable boundary layer and physical parameterization schemes, will greatly improve the sea fog forecasts.
