摘要1995年5月16日，一场超级单体风暴在堪萨斯的花园城市附近产生了一场F1级龙卷风。这一事件首次提供了合成由国家大气研究中心开发的称为Electra多普勒雷达的新机载雷达平台收集的数据的机会。一份配套文件介绍了低层和中层中气旋的演变情况。在本文中，事件的序列，触发龙卷风内的中气旋环流。在第一部分中记录的阻塞下沉气流似乎促进了“涡破裂”，导致多个涡度中心的产生。正是这些中心之一，加强成花园城市龙卷风。文中还给出了观测到的壁云与发展中的钩状回波和运动风场的雷达反射率之间的结构关系。尽管墙云看起来是均匀的...
Abstract On 16 May 1995, a supercell storm produced an F1 tornado near Garden City, Kansas, during VORTEX (Verification of the Origins of Rotation in Tornadoes Experiment). This event provided the first opportunity to synthesize data collected by a new airborne radar platform called ELDORA (Electra Doppler radar) developed by the National Center for Atmospheric Research. The evolution of the low- and midlevel mesocyclone was presented in a companion paper. In this paper, the sequence of events that triggered tornadogenesis within the mesocyclone circulation is shown. The occlusion downdraft, documented in Part I, appears to promote “vortex breakdown” resulting in the generation of multiple vorticity centers. It is one of these centers that intensifies into the Garden City tornado. The structural relationship between the observed wall cloud and the radar reflectivity associated with the developing hook echo and the kinematic wind field is also presented. Although the wall cloud appears to be uniform there ...
