Short summary
Air pollution in the North China Plain is tends to be influenced by El Niño-Southern Oscillation (ENSO) and stratospheric Quasi-Biennial Oscillation (QBO). During El Niño and easterly QBO, pollution rises, while La Niña and easterly QBO improve air quality through changes in atmospheric circulation and weather conditions.

Unlike traditional numerical studies, we apply a high-resolution Earth system model, improving simulations of surface ozone and large-scale circulations such as atmospheric blocking. Besides local heat waves, we quantify the impact of atmospheric blocking on downstream ozone concentrations, which is closely associated with the blocking position. We identify three major pathways of Rossby wave propagation, stressing the critical role of large-scale circulation in regional air quality.

The intraseasonal NAAA usually establishes quickly on day −3 with a life span of 8 days. Further results revealed that the probability of regional PM2.5 pollution related to the NAAA for at least 2 days in the NCP is 80% in NDJ period 2000–2021. Particularly, air quality in the NCP tends to deteriorate on day 2 prior to the peak day of the NAAA and reaches a peak on day −1 with a life cycle of 4 days. The corresponding meteorological conditions support these conclusions.

The Yellow-Bohai Sea region lies downwind of heavily polluted East Asia. Research reveals how land and ship pollution impact coastal air in Qingdao and nearby seas. Ship and coal emissions worsen marine air quality, with summer zinc and arsenic levels exceeding land. Spring carries city pollution seaward, summer pushes ship emissions ashore. Using 81 air samples, the study shows seasonal shifts between dust, industry & combustion sources, highlighting growing human impacts on marine ecosystems.

The effectiveness of this assimilation system and its sensitivity to the ensemble member size and length of the assimilation window are investigated. This study advances our understanding of the selection of basic parameters in the four-dimensional local ensemble transform Kalman filter assimilation system and the performance of ensemble simulation in a particulate-matter-polluted environment.

Aerosol particles from mainland can transport to oceans and deposit, providing soluble Fe and affecting phytoplankton growth. Thus, we studied the dissolution process of aerosol Fe and found that photochemistry played a key role in promoting Fe dissolution in clean conditions. RH-dependent reactions were more influential in slightly polluted conditions. These results highlight the distinct roles of two weather-related parameters (radiation and RH) in influencing geochemical cycles related to Fe.

PM2.5 pollution is a major air quality issue deteriorating human health, and previous studies mostly focus on regions like the North China Plain and Yangtze River Delta. However, the characteristics of PM2.5 concentrations between these two regions are studied less often. Focusing on the transport corridor region, we identify an interesting seesaw transport phenomenon with stagnant weather conditions, conducive to PM2.5 accumulation over this region, resulting in large health effects.

New particle formation is an important source of atmospheric particles, exerting critical influences on global climate. Numerical models are vital tools to understanding atmospheric particle evolution, which, however, suffer from large biases in simulating particle numbers. Here we improve the model chemical processes governing particle sizes and compositions. The improved model reveals substantial contributions of newly formed particles to climate through effects on cloud condensation nuclei.

Air pollution can be cleaned up quickly by a cold air outbreak (CAO) but reappears after a CAO. By quantifying the CAO properties, we find the coldness and depth of the cold air mass are key factors affecting the rapid (slow) reappearance of air pollution through modulating the atmospheric boundary layer height and stability. We also find that the spatial pattern of CAO in high-latitude Eurasia a few days ahead can be recognized as a precursor for the reappearance of air pollution.

Short summary
The North China Plain (NCP) suffered many periods of haze in winter during 1985–2015, related to the rainfall-induced diabatic heating over southern China. The haze over the NCP is modulated by an anomalous anticyclone caused by the Rossby wave and a north–south circulation (NSC) induced mainly by diabatic heating. As a Rossby wave source, rainfall-induced diabatic heating supports waves and finally strengthens the anticyclone over the NCP. These changes favor haze over the NCP.
