Short summary

The Tibetan Plateau has been experiencing a rapid warming during the last 40 years, particularly in winter. The warming leads to an increase in the planetary boundary layer height and a decrease in the relative humidity in the Sichuan Basin, causing a reduction of PM_2.5 concentration by 17.5 % (~25.1 μg m⁻³), of which the reduction in secondary aerosols is 19.7 μg m⁻³. These findings indicate that the warming plateau plays an important role in mitigating air quality in downstream.
