| 摘 要： | 对首都机场寒潮强风极值出现条件进行了初步分析：当低层到中高层的槽线上下位置呈垂直或前倾的条件下，强风的风速大小与锋区强度和层结曲线平行于干绝热线的厚度成正相关。

| Abstract: | The conditions for the strong wind extreme value of the cold wave in Beijing Capital Airport are analyzed. The result shows that when the trough position from the low level to the middle and upper level is vertical or forward tilting, the values of the strong wind speed have a positive correlation with the intensity of frontal zone and the parallel depth between stratification curve and dry adiabat. |

| Keywords: | cold wave with strong wind forward tilting trough momentum downwash |
