中文摘要: 估计了1975年6月7日山东省栖霞县一次强龙卷风的环流参数:最大风速可达62m·s-1,最大平移风速12m·s-1,最大旋转风速50m·s-1,总压力降为275hPa。对龙卷风产生的极强的瞬时荷载、强烈的旋转扭曲、突然压力降及飞射物造成的破坏力进行了估计。

Abstract:Using the cyclostrophic wind equation of Rankine vortex, the vortex features of a tornado happened in Xixia county of Shandong Province are calculated. The maximum wind speed of a strong tornado, the maximum translatory velocity, the maximum tangential velocity, and the maximum atmospheric pressure drop are 62m·s-1,12m·s-1,50m·s-1 and 27.5hPa, respectively. The assessment of tornado′s destructibility is given.
