This hypothesis describes the direction of wind among the mesocyclone / funnel of tornado. I depended only on my observations of the tornadoes videos caught by tornado-chasers heroes. This hypothesis states that the wind in the inside part of the funnel mainly moves from up ‘the cloud’ toward down ‘the ground’. The wind in the inside part of the funnel moves in a spiral way from up to down. Then when the wind reaches the ground it will spread in a rotary plan direction in relation to the ground and it will be reflected back toward upward in a spiral way again. This upward reflection could happen too at any level of the tornado-funnel level so the wind in the outside part of the funnel moves in a spiral way from down to up and this causes the suction power of the tornado.
