At its mature stage,the horizontal size of the squall line system reached the upper limit of meso-β scale,with double bands of strong radar echo inside. The features of cloud and weather phenomena associated with the two bands differed significantly.
对本次飑线系统及伴随的强对流天气现象的分析发现,在系统成熟阶段,地面雷暴高压和飑前阵风锋达到最强且强对流天气现象出现范围最大,飑线系统水平尺度达到β中尺度上限,系统内存在两条对流强回波带,它们之间云的特征及强对流天气现象具有明显差异。

飑线中的狂风雷暴。
飑线的产生经常与不稳定能量和垂直风切变相联系。
The occurrence of squall lines is frequently associated with instability energy and vertical wind shear.
分析指出，该飑线系统是由高空槽前型的上干下湿引起的不稳定强对流天气。
The squall line is a kind of instable and strong convective weather caused by the air with upper-layer dry and lower-layer wet in front of the upper-troposphere trough.
