摘　　要：2021年7月11日,河北省邢台市临西县发生强风灾害,根据现场灾害调查情况,结合多普勒天气雷达探测资料,确认此次强风灾害为龙卷所致。主要结果如下:19:36—20:00(北京时)龙卷自南向北行进约5.4 km,持续时间<30 min,致灾宽度为20~120 m;龙卷强度在生命期的中期经过卢庄村时达到最强,为EF2级强龙卷;砖混结构的民房或墙体、彩钢板简易房等在龙卷袭击后损毁明显。On 11 July 2021,Linxi County of Xingtai City,Hebei Province experienced severe wind damage.The on-site damage survey,combined with the observation data from Doppler radar,proves that the wind damage was caused by a tornado.The results suggest that the tornado moved in the south-to-north direction during 19:36-20:00 BT,with a damage swath of 20-120 m wide and 5.4 km long.The intensity of the tornado reached its strongest level of EF2 in the intermediate phase of its life history when passing by Luzhuang Village.Civil buildings or walls with brick and concrete structures,as well as temporary buildings made of colored steel plates,were significantly damaged after the tornado attack.
