| 摘 要： | 该文分析了1988年5月初出现于苏皖东部地区的一次飑线。下部深厚的辐合层与上部强烈的辐散层迭置为其存在空间；低层低空急流轴与θs e场高值轴几乎重合，使该空间不仅有丰富的能量贮存，而且有利于扰动动能释放；沿低空急流的重力波传播与高压后部回流冷空气前缘的重力波“相交处”，冲击力可能很大，飑线正在此处出现。

| Abstract: | A squall line weather process on 2 May 1998 was analysed over the eastern Anhui-Jiangsu provinces. The analysed result shows that there was a deep convergence layer on the low level, and severe divergence layer on the upper; the axis of low stream let stream on the low level was almost coincident with the axis of high value of the θse field. So that the space of the squall line not only had abundant energy storage, but also was favourable to the release of disturbance kinetic energy. In the crossing site of the gravity wave along the low jet stream and that of forward sector of backflow, the impulsive force might be very strong, and a squall line just appeared there. |
