Short summary
Downward wave coupling (DWC) events impact high-latitude stratospheric ozone in two ways: (1) reduced dynamical transport of ozone from low to high latitudes during individual events and (2) enhanced springtime chemical destruction of ozone via the cumulative impact of DWC events on polar stratospheric temperatures. The results presented here broaden the scope of the impact of wave–mean flow interaction on stratospheric ozone by highlighting the key role of wave reflection.
