Short summary
We analyzed a haze front event involving warm–dry downslope flow in December 2015 in Beijing, China. The haze front was formed by the collision between a clean warm–dry air mass flowing from a nearby mountainous region and a polluted cold–wet air mass over an urban area. We found that the polluted air advanced toward the clean air, resulting in a severe air pollution event. Our study highlights the need to further investigate the warm–dry downslope and its impacts on air pollution.

Using near surface atmospheric pollutant reanalysis and remote sensing measurements, a dipole-like spatial pattern of near surface ozone trap across two megacities of the Sichuan Basin is demonstrated during 2013–2019. Unexpectedly, Chongqing has the deeper ozone trap compared to Chengdu despite its lower urbanization level. Results showed the ozone trap pattern aligns more closely with meteorological condition rather than chemical condition.

This study collected 1897 ozonesondes from two Chinese megacities (Beijing and Hong Kong) in 2000–2022 to investigate the climatological vertical heterogeneity of lower-tropospheric ozone distribution with a mixing-layer-height-referenced (h-referenced) vertical coordinate system. This vertical coordinate system highlighted O3 stratification features existing at the mixing layer–free troposphere interface and provided a better understanding of O3 pollution in urban regions.

This study presents the first systematic assessment of observationally constrained UTLS O3 variability over the Northeast Asia region in the framework of upper-level circulation pattern classification. The results indicate that lower-stratospheric O3 exhibits a far stronger sensitivity to upper-level circulation patterns when compared with upper-tropospheric O3. The progression of the East Asian Trough plays a critical role in determining the location and intensity of O3 enhancements.

Short summary
Fog is an important meteorological phenomenon that affects visibility. Aerosols and the planetary boundary layer (PBL) play critical roles in the fog life cycle. In this study, aerosol-induced changes in fog properties become more remarkable in the second fog (Fog2) than in the first fog (Fog1). The reason is that aerosol–cloud interaction (ACI) delays Fog1 dissipation, leading to the PBL meteorological conditions being more conducive to Fog2 formation and to stronger ACI in Fog2.

Short summary
This research examines foehn events in Beijing using weather station data from 2015 to 2020. We found an average of 56.5 foehn days annually, primarily in winter. These winds can raise temperatures significantly and are associated with air pollution levels. Strong foehn winds tend to reduce pollution, while weaker winds may increase it. Our study highlights the impact of foehn events on air quality, providing valuable insights for urban planning and environmental management.
