在过去的二十年里，通过研究龙卷风后建筑物的破坏，我们学到了很多东西。尽管如此，在确定破坏是由龙卷风还是直线风造成的基本层面上仍然存在问题。过去对风害的研究经常揭示，物体在龙卷风中沿着沿着直线路径移动，在直线风中沿着弯曲轨迹移动。物体的飞行特性和地形的可变性只是造成这种不确定性的许多因素中的两个因素。因此，当使用单点损伤来确定风场类型时，损伤调查人员必须谨慎。
In the past two decades, much has been learned by studying building damage in the wake of tornadoes. Still, there are problems at the basic level in deciding whether the damage was caused by tornadoes or straight-line winds. Past studies of wind damage have frequently revealed that objects were transported along straight paths in tornadoes and followed curved trajectories in straight-line winds. The flight characteristics of objects and the variability of the terrain are only two of the many factors which cause this uncertainty. Thus damage investigators must exercise caution when using a single point of damage to determine the type of wind field.
