Research Abstract

On 6 May 2012, a F3 tornado, which was one of the most destructive tornadoes ever in Japan, hit Tsukuba City in eastern Japan. To clarify the structure of a tornado-producing storm and mechanisms of tornadogenesis, detailed analyses were conducted using polarimetric radar data and high-resolution simulation results. The storm, which spawned the tornado, exhibited characteristics of a typical supercell storm as often observed in midwestern United States. The tornadogenesis was preceded by "Tornado Cyclone" with a diameter of about 1 km. The rear-flank downdraft associated with heavy precipitation was crucial for vorticity generation of the tornado.
