| 摘 要： | 本文利用声雷达探测、80米铁塔观测的风、温资料和探生资料,结合天气图分析,讨论锋后强天气过程的边界层结构。结果表明,冷锋后大风的形成是与高层下沉冷空气有着密切的关系,并与边界层过程也有密切的联系。 资料分析表明,大风天气过程的形成可能是下沉运动引起的边界层动量和热量输送相互作用的结果。

| Abstract: | The structure of the boundary layer for the process of the strong weather after the passage of a cold front is discussed, using the data of the acoustic radar,the temperature and the wind speed obtained from the 80 meters meteorological tower, and the radiosonde sounding and the analyses of the weather maps. It is shown that the formation of the strong wind is closely correlated to the subsidence of the upper cold air, as swell as the process of the boundary layer. The analytical results indicate that the weather process of the strong wind is formed probably by the interaction of the momentum flux with the haat flux due to the subsidence of the cold air in the boundary layer. |
