Abstract : The numerical model which employs observed stratospheric winds to advect simulated tracers was developed. The model successfully reproduces many qualitative features of the observed fields of both ozone and radioactive debris. As the tracers evolve, the horizontal eddies constitute the principal process modifying the tracer zonal mean. Although the vertical eddies and the zonal mean cell are both an order of magnitude weaker than this process, the latter of these tends to always act in the same sense so that its effect becomes more important over long periods of time.
