对龙卷风最大风速的估计是由 理论计算和通过间接手段，如结构 损害 然而，到目前为止，对这些速度的直接验证 稀疏。 通过静态研究， 多普勒雷达，但样本量小，由于雷达地平线 问题是，在地面附近没有测量。 与洛斯阿拉莫斯国家实验室的一位科学家 实验室，主要研究者将使用小型便携式 多普勒雷达接近龙卷风在一个安全的，但近距离， 测量龙卷风及其附近环境的风速。 甚至 虽然龙卷风是罕见的事件，首席研究员，工作 与NOAA的国家严重风暴实验室合作， 在过去成功拦截龙卷风 收集的数据将与各种预测进行比较。 龙卷风形成的理论，并将首次提供， 对某些理论的直接验证或反驳。

Estimates of maximum wind speeds in tornadoes has been made from theoretical calculations and through indirect means such as structural damage. To date, however, direct verification of these speeds has been sparse. Some measurements have been made by stationary research Doppler radars, but the sample size is small and due to radar horizon problems, no measurements are available near the ground. In conjunction with a scientist from the Los Alamos National Laboratory, the Principal Investigator will use a small portable Doppler radar to approach tornadoes at a safe, but close, range and measure wind velocities in the tornado and its near environment. Even though tornadoes are rare events, the Principal Investigator, working with NOAA's National Severe Storms Laboratory, has been very successful in the past in intercepting tornadic storms. The collected data will be compared with predictions from various theories of tornadic formation and will provide, for the first time, direct verification or refutation of some of these theories.
