Short summary
This study examines how air pollution affects snowfall during a winter storm in central China. Using a detailed computer model of weather and air pollution, we compared conditions with different pollution levels. We find that pollution can either increase or decrease snowfall, depending on air moisture and whether snow forms mainly as ice or liquid. Pollution mainly changes how often snowfall occurs, rather than where it falls, improving understanding of weather and climate impacts.

The impacts of agricultural fertilization on nitrogen oxide and air quality are becoming more pronounced with continuous reductions in fossil fuel sources in China. We report that atmospheric nitrogen dioxide pulses driven by agricultural fertilization largely complicate air pollution in the North China Plain, highlighting the necessity of agricultural emission control.

This study uses a cloud-resolving model to examine how aerosols influence a mesoscale convective system (MCS) in central China via aerosol–radiation interaction (ARI) and aerosol–cloud interaction (ACI). Without ARIs, added aerosols do not significantly affect precipitation due to cloud competition for moisture. ARIs can stabilize or enhance convection. High aerosol levels lead to a combined ARI and ACI effect that greatly reduces precipitation.

Brown carbon (BrC) is a type of airborne particle produced from various combustion sources which is light absorption. Historically, climate models have categorizing organic particles as either non-absorbing or purely reflective. Our study shows that BrC can reduce the usual cooling effect of organic particles. While BrC is often linked to biomass burning, however, BrC from fossil fuels contributes significantly to atmospheric heating.

This study investigated how cloud–radiation interactions influence ozone formation in a warming climate. Using measurements, reanalysis data, and models, we found that cloud–radiation interactions can worsen O3 pollution, and climate warming will amplify the influence. We highlight that climate change will pose greater challenges for China's O3 pollution prevention and control, and actions such as reducing O3 precursors emissions and mitigating climate change are urgently needed.

Short summary
Due to their lower diffusion capacities and higher conversion capacities, urban areas in Xi’an experienced severe ozone pollution in the summer. In this study, a campaign of comprehensive field observations and VOC grid sampling was conducted in Xi’an from 20 June to 20 July 2019. We found that Xi'an has a strong local emission source of VOCs, and vehicle exhaust was the primary VOC source. In addition, alkenes, aromatics, and oxygenated VOCs played a dominant role in secondary transformations.

Short summary
Air pollution in China has shifted from particles to ozone as a main concern in warm-seasons. We combined ten years of observations with model simulations to explore how ozone and secondary particles change in the Guanzhong Basin. We find that chemical drivers shift during the season, leading to different pollution responses. These insights point to targeted, season-specific strategies that can improve air quality more effectively.
