We simulated supercell type tornadoes with our newly designed mesocyclone simulator and a wall jet generator. The fluctuating velocity of the tornado is measured near the floor by using an X-probe and hotwire anemometers. Its spectrum showed that the velocity field at the lower layer of the tornado was highly turbulent. Its peak corresponds to the existence of suction vortices in multiple vortex type tornado.
