The results show that the dynamic force and thermal conditions of forming the squall line were the convergence of cold air from Mongolia cold vortex and the warm-humid air current before west trough to form the convectional system at moderate 3 scale; the rapid development and southward shift of MβCSs was caused by a strong unstable stratification and the shear line of suitable vertical wind; a heavy hail occurred after a vertical liquid water content over 65 kg/m^2 was firstly measured by weather radar; a sharp reduction of VIL indicates that a disaster strong wind will occur at soon.

结果表明：蒙古冷涡旋转下甩冷空气与西风槽前的暖湿气流汇合，形成中p尺度的对流系统是飑线形成的前期动力和热力条件；强的不稳定层结和合适的垂直风切变导致了MβCSs的迅速发展和南压；在天气雷达首次观测到垂直液态水含量值超过65kg/平方公尺后2h内出现了大冰雹；垂直液态水含量的突然减小标志着灾害性大风的开始。

The squall line, including surface wind and squall line structure, is simulated well by the WRF model.

3WRF模式对这次飑线过程的主要特征模拟较好，包括地面风场和飑线的结构。

Based on the new generation weather radar data in Guilin, a severe squall line event ahead of a front occurred in Guangxi on 5, May 2005 is analyzed to study the evolution of the squall and its convective cell.

利用位于桂林的新一代天气雷达资料对2005年5月5日影响广西桂林的锋前强飑线过程进行了详细的分析。

According to short term monitoring data, it appears that the new cell echo before the radar echo is advantage for the development and maintenance of the squall line. And the initialization of new cell is associated with boundary-layer convergence line. As a result, mesonet data is useful fur to research on squall line.

从短时监测的资料分析，飑线发展过程中，雷达主回波前方的新生的回波单体对飑线发展和持续十分有利，而它的新生与边界层的辐合线相联系，因此，充分利用中尺度地面观测资料有助于飑线的发展研究。

In order to effectively forecast or forewarn squall lines and verify the effectiveness of the nowcasting system,a squall line occurring on 1 August 2006 in Beijing is analyzed by using conventional weather data,automatic weather station data,Doppler radar data,and the nowcasting system.

为了对飑线这类强天气作有效的预报、预警，同时对临近预报系统的预报效果作初步的检验，利用常规气象资料、自动站资料、多普勒雷达资料，结合临近预报系统分析了2006年8月1日北京地区飑线天气过程。

The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.

结果表明：飑线是在有利的天气形势下发生的，飑线上强风暴的强度大、高度高；飑线速度剖面图中显示有低层辐散、中层辐合、高层辐散的特征；垂直累积液态水含量迅猛增加到比较大的数值对冰雹预报有很好的指示意义；在冰雹指数产品中以强冰雹概率大于30%作为冰雹预警门限则有较好的效果；边界层辐合线起到了触发对流和加强对流的作用。
