2023年6月1日辽宁省多龙卷风灾害调查及特征分析
Investigation and characteristic analysis of the multiple tornado disasters in Liaoning province on June 1,2023
摘要
Abstract
Utilizing datasets of field disaster investigations,recorded videos,orthophoto maps,and satellite images,the study analyzed the intensity,path length,visual characteristics,and evolution of multiple tornadoes that occurred on June 1,2023,in Fuxin,Faku,Kangping,and Kaiyuan of Liaoning province.The results indicated that the torna-do in Fuxin is a moderate tornado(EF1)with a path length of approximately 3 km.The color changes of the fun-nel cloud reflect variations in the underlying surface and the tornado evolution.The twin tornadoes in Faku are both classified as weak(EF0)with path lengths of 0.8 km and 0.6 km,respectively.The Kangping tornado is also weak(EF0)with a path length of about 1.0 km,whereas the tornado in Kaiyuan is strong(EF2)with a path length of approximately 11.0 km.Both satellite and orthophoto images show clear evidence of tornado damages,and a nearly circular cycloidal mark is observed.The tornado radar products in Liaoning province only issue an a-lert for the Kaiyuan tornado,while the other tornadoes are lack of clear signatures in radar products.关键词
