Short summary

Using the GEOS-Chem model, the impact of the quasi-biennial oscillation (QBO) on summertime tropospheric O₃ in China is investigated. In the warm phases of sea surface temperature anomalies over the eastern tropical Pacific, the QBO has a significant positive correlation with near-surface O₃ concentrations over central China. The QBO impacts on O₃ pollution in China are mainly a result of changing vertical transport of O₃.
