Short summary

Heatwaves (HWs) paired with higher ozone (O₃) concentration at surface level pose a serious threat to human health. Taking Beijing as an example, three unfavorable synoptic weather patterns were identified to dominate the compound HW and O₃ pollution events. Under the synergistic stress of HWs and O₃ pollution, public mortality risk increased, and synoptic patterns and urbanization enhanced the compound risk of events in Beijing by 33.09 % and 18.95 %, respectively.
