We introduce experimental approaches to investigate flow environment generating tornadoes. Non-supercell tornado-like vortices can be realized with the shear line of simulated cold outflow and simulated updraft. On the other hand, the combination of rotating updraft called as mesocyclone and cold outflow can cause various supercell tornado-like vortices. We expect that the experimental conditions realizing tornado-like vortices will be helpful to improve the accuracy of tornado watch.
