| Research Abstract |
We developed the experimental simulator reproducing the environment of tornado outbreak an demonstrated that various tornadoes were spawn depending on the height and rotation of mesocyclone. This fact will contribute to improvement of the prediction of tornado outbreak. We also showed the detailed structures of tornado-like vortices. We found that 80% of misocyclones observed by radars arose in Tosa Bay. The relationship between Fukuoka tornado and mesocyclone was also shown by radar observation. We demonstrated the developing process of non-supercell tornado with a meteorological model simulation.
