Short summary

The ozone layer protects the life on the Earth by absorbing the ultraviolet (UV) radiation. Beside the long-term trend, there are strong interannual fluctuations in stratospheric ozone. The quasi-biennial oscillation (QBO) is an important interannual mode in the stratosphere. We show some new zonally asymmetric features of its impacts on stratospheric ozone using satellite data, ERA5 reanalysis, and model simulations, which is helpful for predicting the regional UV radiation at the surface.
