In this medium-range prediction method for the forest fire danger rating, the Forest Fire Danger Rating 801 are used to be the predict and. The historical data for upper 500Hpa and the data for geostrophic vorticity are used to be the predictor. The prediction equations are formulated . The medium-range prediction charts for upper 500Hpa issued by ECMWE are used to be the effective predictands to calculate the 3-6 days forest fire danger rating for the 10 monitor stations over the forest area on the Xin'an Mountains in spring. According to the testing results, the prediction accuracy for this method is over 70% .
