The feedback of the radiative forcing caused by the ozone QBO in the tropics on the ozone variation itself is examined with a 2-D model. Simulations show that the effect of the QBO in solar heating on the ozone and meridional circulation oscillations are negligible, which contradicts the proposal of Hasebe (1994). The impact of the ozone variation on the photolysis QBO is also presented and is shown to be important. Its overall effect is to damp the amplitude of ozone oscillation through its modulation of the oxygen photolysis rate. ¿ American Geophysical Union 1996
