| Abstract: | Using the gale materials from March to May in 1981--2000, and analyzing the cold air path, the paper divides gale into northeast type and northwest type. Firstly, screen for the forecasting factors by adopting stepwise regression analysis; and then, establish predictive equation by use of the forecasting factors with better effects. |
