On-Site Damage Survey and Intensity Rating for Tornado in Linxi County,Hebei Province on 11 July 2021
摘要
Abstract
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.关键词
