| Abstract: | Based on numerical forecast products （MM5）, a fog forecast model is established with the statistical method for highways and the nearby 460 weather stations in North China. The results of the verification for more than 2 years show that CSI （Critical Success Index） for visibility being less than 5 km for 24 hours forecast is 0.61 at Beijing and 0.68 at 7 stations along the Jing Jin Tang highway, respectively.The mean fog or not forecast accuracy rates are both 0.81. Two events of low visibility weather in 2007 are discussed and forecasted successfully, which indicates the method is applicable for fog forecasting. |
