Short summary
Cloud droplets are vital for rainfall and climate, and tiny airborne particles called aerosols can change their size and number. Using airplane observations over Hebei and simulations, we found that aerosols strongly affect droplet vertical distribution. Under high aerosols, lower droplets are larger and more numerous; under low aerosols, upper droplets are larger. These changes affect cloud development, precipitation, and atmospheric energy.

Atmospheric new particles formation plays an important role in air quality and climate change, but it does not always appear even in the similar situation. Using ground measurements and vertical observations, we found this process occurs only when the ozone increases while background pollution decreases at the same time, which is mainly controlled by the development of the boundary layer. The finding helps us better understand particle formation in complex atmospheric environments.

Using aircraft and ground-based observations, this study analyzes a spring snowstorm over North China Plain. It reveals distinct microphysics: stratiform regions feature ice growth by deposition/aggregation, while thunderstorms areas show higher supercooled water content and riming. The precipitation particle distribution characteristic of thunderstorm areas is also revealed. The vertical precipitation structure varies across stages, influenced by phase transitions and updrafts.

Short summary
The Tibetan Plateau has little available moisture and energy, so convection is hard to develop. Large-eddy simulations indicates the lake promotes low-level moistening and lowers the barrier to convective initiation, produces shallow clouds and week rain. Mountain alone force lifting, yet the lack of moisture limits terrain-driven precipitation. Lake-mountain coupling is key: the mountain lifts lake-supplied moisture but can also block moisture transport, reshaping precipitation patterns.

We applied various criteria to identify springtime ozone depletion events (ODEs) at Utqiaġvik, Arctic, and investigated the influence of using different criteria on conclusions regarding the characteristics of ODEs. We found that criteria using fixed thresholds or monthly average-based thresholds were more suitable for identifying ODEs than the others. Applying a threshold that varies with the monthly average or stricter fixed thresholds also indicated a more significant reduction in ODE occurrences.

This study reveals a unique driver of the Tibetan Plateau (TP) thermal forcing of the interannual variations in stratosphere-to-troposphere transport (STT) of ozone with diverse structures. Anomalous strong TP thermal forcing induces anticyclonic anomalies in the upper troposphere over the TP, which strengthens and attenuates the northern and southern branches of the westerly jet, intensifying (weakening) the westerly trough for more (fewer) tropopause folds of ozone STT over the East Asian region.

We proposed a composite statistical method to identify the quasi-weekly oscillation (QWO) of regional PM2.5 transport over China in winter from 2015 to 2019. The QWO of regional PM2.5 transport is constrained by synoptic-scale disturbances of the East Asian winter monsoon circulation with the periodic activities of the Siberian high, providing a new insight into the understanding of regional pollutant transport with meteorological drivers in atmospheric environment changes.

Our research explored changes in ozone levels in the northwest Pacific region over 30 years, revealing a significant increase in the middle-to-upper troposphere, especially during spring and summer. This rise is influenced by both stratospheric and tropospheric sources, which affect climate and air quality in East Asia. This work underscores the need for continued study to understand underlying mechanisms.

We studied the impact of stratospheric intrusions (SIs) on tropospheric and near-surface ozone in Central and Eastern China from a stratospheric source tracing perspective. SIs contribute the most in the eastern plains, with a contribution exceeding 15 %, and have a small contribution to the west and south. Western Siberia and Mongolia are the most critical source areas for indirect and direct SIs, with the Rossby wave and northeast cold vortex being important driving circulation systems.

We reveal a significant mechanism of stratospheric O3 intrusion (SI) into the atmospheric environment induced by an extratropical cyclone system. This system facilitates the downward transport of stratospheric O3 to the near-surface layer by vertical coupling, involving the upper westerly trough, the middle northeast cold vortex, and the lower extratropical cyclone in the troposphere. On average, stratospheric O3 contributed 26.77 % to near-surface O3 levels over the North China Plain.

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.

Based on the radiosonde observations, an anomalously warm layer is measured at altitudes between 500 and 300 hPa over the Tarim Basin (TB) with an average intensity of 2.53 and 1.39 K in the spring and summer, respectively. The heat contributions of dust to this anomalously warm atmospheric layer in spring and summer were 13.77 and 10.25 %, respectively. Topographically, the TB is adjacent to the Tibetan Plateau; we propose the concept of the Tibetan heat source’s northward extension.

This study revealed the impact of anthropogenic emissions and meteorological conditions on PM2.5 decline in the regional transport of air pollutants over a receptor region in central China. The meteorological drivers led to upwind accelerating and downward offsetting of the effects of emission reductions over the receptor region in regional PM2.5 transport, and the contribution of gaseous precursor emissions to PM2.5 pollution was enhanced with reduced anthropogenic emissions in recent years.

Focusing on a heavy haze pollution event in the Sichuan Basin (SCB), we investigated the elevated 3D structure of PM2.5 and trans-boundary transport with the WRF-Chem simulation. It is remarkable for vertical PM2.5 that the unique hollows were structured, which which occurred by the interaction of vortex circulations and topographic effects. The SCB was regarded as the major air pollutant source with the trans-boundary transport of PM2.5 affecting atmospheric environment changes.

Short summary
We investigated how new air particles form in cities and affect clouds. Our year-long study revealed a key seasonal pattern: while particle formation events are most frequent in spring, they are surprisingly inefficient at creating the seeds for clouds due to high pollution. In contrast, the cleaner summer air, despite having fewer events, allows the new particles to grow larger and much more effectively enhance potential cloud formation.
