The principal possibility of tornadoes physical modeling in vitro without use of mechanical twisting devices has been shown. The results of experiments on studying related to opportunities of whirlwinds control are given. The offered and approved method of impact on whirlwinds (tornado), consisting in an arrangement of obstacles in the form of vertical grids in a way of vortex structures distribution, has been described. The method efficiency is verified in vitro by studying of specified
