摘要1987年5月25日下午，雷暴，其中一些龙卷风和产生大冰雹，在得克萨斯州狭长地带的干线附近形成。这篇文章讨论了俄克拉荷马州大学风暴拦截小组在德克萨斯州格鲁弗南部发展中的积雨云上升气流中释放的探测。探测结果显示，大气层高度为500 mb时，大气层内的温度超过4°-6 ° C，上升气流速度在6 - 7 km AGL之间为35-40 m s− 1，这与包裹体理论非常吻合。雷达观测到的细线沿着干线出现，然后向西撤退，这也是先前两个案例研究中注意到的。
Abstract During the afternoon of 25 May 1987, thunderstorms, some of which were tornadic and produced large hail, formed near a dryline in the Texas Panhandle. This note discusses a sounding released into the updraft of a developing cumulonimbus south of Gruver, Texas by a University of Oklahoma storn-intercept team. The sounding indicated a nearly pseudo-moist-adiabatic lapse rate, a temperature excess of 4°–6°C over the environment at 500 mb, and updraft speeds of 35–40 m s−1between 6 and 7 km AGL, in good agreement with parcel theory. A radar-observed fine line appeared along the dryline and retreated westward, as was also noted in two earlier case studies.
