摘　　要：通过雷达拼图、卫星云图对2017年8月8日发生在华北地区的冰雹天气进行了分析,了解到此次冰雹是在东北冷涡的影响下发生的,华北地区上空有较强的冷平流,天气形势不稳定,有中尺度触发系统即可诱发强对流,雷达拼图中有中尺度辐合系统的充沛能量使零散回波逐渐增强,为冰雹天气创造了良好的条件。卫星云图上,在华北地区的北部有一片高温区域,有一较为强盛的对流云团,这一对流云团为冰雹天气提供了重要的条件。The hail weather in North China on August 8,2017 was analyzed through the radar mosaic and satellite cloud images.Through analysis,it was learned that the hail occurred under the influence of the Northeast Cold Vortex.There was a strong cold advection over North China,and the weather situation was not very stable.A mesoscale trigger system could induce strong convection.The radar mosaic had a mesoscale convergence system,which was full of energy,so that scattered echoes were gradually enhanced,It creates good conditions for hail weather.On the satellite cloud map,there was a hightemperature area in the north of North China,with a relatively strong convective cloud cluster,which provides important conditions for hail weather.
