The beneficial effects of the present invention are: the present invention sets an angle adjustment mechanism for adjusting the angle of the deflector in the simulation device body, and changes the speed direction of the airflow entering the plexiglass cover through the angle adjustment mechanism, thereby changing the vortex ratio of the tornado. The rotation of the angle adjustment mechanism drives the deflector to rotate together, avoiding the complicated steps of adjusting the deflector separately and reducing the error of manual adjustment. The wind speed of the exhaust fan can be measured, the angle scale is set in the arc groove, the inflow angle can be read, and the height of the inflow area is also known, so that the swirl ratio can be calculated, and the replacement of the deflector and the base can also be avoided.
