Numerical results of the photochemical relaxation of large vertical scale height ozone density perturbations are presented to illustrate the importance of opacity effects. Instabilities generated by opacity changes are shown to occur only for ungeophysically large disturbances. They have a short growth phase before eventually decaying to the unperturbed state. For disturtances with a vertical scale height comparable to the ozone scale height analytic results from the linear perturbation theory in Paper I accurately describe the joint photochemical-radiative relaxation above 35 km.
