Short summary
We study the response of Chl-a to spring dust variability in the Chinese marginal seas over 2003–2023, revealing contrasting regional responses driven by distinct synoptic circulation patterns. Mongolian cyclones in the north and anticyclones in the south drive opposing air–sea heat flux anomalies and MLD adjustments that regulate Chl-a on daily timescales. Our study highlights synoptic-scale atmospheric forcing and air–sea heat exchange as key pathways linking dust to phytoplankton variability.

We use the chemistry version of the Weather Research and Forecasting model coupled with spectral bin microphysics to investigate how meteorological conditions impact aerosol–cloud interactions (ACI) under different pollution regimes. Our findings highlight the changes in aerosol effects on clouds and precipitation under varying thermodynamic conditions, as well as the sensitivity of ACI to meteorological conditions under different pollution regimes, which help to clarify the mechanisms behind the nonlinear variation of ACI with environmental conditions.

Short summary
Ship observations revealed lower sea salt aerosol (SSA) concentrations during Southern Ocean cyclones than non-cyclones. GEOS-Chem modeling showed SSA concentrated northwest of the cyclone center. Cyclone-associated strong winds drove 63 % of total SSA emissions. The warm conveyor belt produced peak ascent at 450 m. Turbulent mixing dominated SSA distribution. Ship position relative to the cyclone explained observed low concentrations.

Short summary
Under cold and clean conditions in the free troposphere, oceanic dimethyl sulfide (DMS) can form new particles. Using data from the field observation and Lana climatology with the FLEXPART model, we evaluated DMS contribution from surface ocean to the free troposphere. We found that cyclone enhances the contribution of oceanic dimethyl sulfide to the free troposphere over the Southern Ocean, suggesting significant DMS-derived new particles likely occurred at high altitudes in the Southern Ocean.

We conduct a comparative analysis of aerosol-cloud responses in liquid-phase clouds under different aerosol and meteorological conditions based on simulations using the WRF-Chem-SBM model. Our findings highlight the different effects of aerosols on clouds and precipitation, as well as variations in the roles of aerosol and meteorological factors influencing aerosol-cloud interactions, in different environment.

We explore aerosol–cloud interactions in liquid-phase clouds over eastern China and its adjacent ocean in winter based on the WRF-Chem–SBM model, which couples a spectral-bin microphysics scheme and an online aerosol module. Our study highlights the differences in aerosol–cloud interactions between land and ocean and between precipitation clouds and non-precipitation clouds, and it differentiates and quantifies their underlying mechanisms.

Using an updated soil reactive nitrogen emission scheme in the Unified Inputs for Weather Research and Forecasting coupled with Chemistry (UI-WRF-Chem) model, we investigate the role of soil NO and HONO (Nr) emissions in air quality and temperature in North China. Contributions of soil Nr emissions to O3 and secondary pollutants are revealed, exceeding effects of soil NOx or HONO emission. Soil Nr emissions play an important role in mitigating O3 pollution and addressing climate change.

From 12 March to 6 April 2016 in Beijing, there were 11 typical new particle formation days, 13 non-event days, and 2 undefined days. We first analyzed the favorable background of new particle formation in Beijing and then conducted the simulations using four nucleation schemes based on a global chemistry transport model (GEOS-Chem) to understand the nucleation mechanism.

We improve the ability of WRF-Chem model to simulate aerosol-cloud physical and chemical processes by coupling a spectral-bin cloud microphysics scheme and online aerosol module, and consequently explore the aerosol-cloud interactions over eastern China and its adjacent ocean in boreal winter. Our study highlights the differences in aerosol-cloud interactions between land and ocean, precipitation clouds and non-precipitation clouds, and differentiates and quantifies their underlying mechanisms.

This study developed a four-dimensional variational assimilation (4DVAR) system based on WRF–Chem to optimise SO2 emissions. The 4DVAR system was applied to obtain the SO2 emissions during the early period of the COVID-19 pandemic over China. The results showed that the 4DVAR system effectively optimised emissions to describe the actual changes in SO2 emissions related to the COVID lockdown, and it can thus be used to improve the accuracy of forecasts.

Short summary
Pollution particles cool climate and offset part of the global warming. However, they are washed out by rain and thus their effect responds quickly to changes in emissions. We show multiple datasets to demonstrate that aerosol emissions and their concentrations declined in many regions influenced by human emissions, as did the effects on clouds. Consequently, the cooling impact on the Earth energy budget became smaller. This change in trend implies a relative warming.

Short summary
This study examines a severe dust event that occurred in western Inner Mongolia (WIM) on 11 April 2025, which reached Hainan by 13 April. Unlike the dust events in 2021 and 2023 that did not affect Hainan, this case was characterized by a south‑moving Mongolian cyclone. Sustained strong northerly winds pushed both the dust plume and the rainband southward; however, the dust remained positioned behind the rainband, thereby avoiding wet scavenging and facilitating its transport to Hainan.
