Building on previous work by Broyles et al. (2003) and Feuerstein et al. (2005), which address the existence of said local tornado alleys, this work inter-compares different tornado alleys and attempts to explain the reasons for their existence. Using tornado reports from around the world, topographic and geographical mechanisms are shown to influence the likelihood of tornado formation in specific regions. Areas of intense tornadic activity are commonly downstream of higher elevation and in close proximity to a significant body of water. In addition, the meteorological profile of an archetypal mesocyclone tornado is created from composited reanalysis data. Such composites are used to bolster the importance of orography and geography in aiding tornadogenesis, as well as identify specialized meteorological parameters that contribute to severe tornado formation in different regions.
