超过250个龙卷风近距离探测已被仔细研究。重点是详细检查风廓线和水深的稳定性。审查了严重风暴报告和相对于移动风暴的邻近数据定位所固有的不确定性。结果发现，小规模的风暴环境不能解决的平均接近数据。在天气尺度上，一个非常大范围的风和稳定性被发现与确认的龙卷风有关。只有轻微的差异，平均龙卷风接近探测，平均探测与破坏性的龙卷风爆发，平均探测与非龙卷风严重雷暴爆发。风暴相对风场被发现是相似的所有类型的龙卷风探测研究。在给定的环境条件下，雷暴流场随雷暴速度的变化而变化。
Abstract Over 250 tornado proximity soundings have been closely studied. Emphasis was given to a detailed examination of the wind profiles and stabilities of the soundings. The uncertainties inherent in severe storm reports, and in the positioning of proximity data relative to moving storms, were examined. It was found that the small-scale storm environment cannot be resolved with mean proximity data. On the synoptic scale a very large range of winds and stabilities was found to be associated with confirmed tornadoes. Only slight differences were found between mean tornado proximity soundings, mean soundings associated with destructive tornado outbreaks, and mean soundings associated with outbreaks of non-tornadic severe thunderstorms. Storm relative wind fields were found to be similar for all types of tornado soundings studied. The storm relative flow fields vary dramatically as thunderstorm velocity changes within a given environment.
