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.

Short summary
Local atmospheric circulations are frequent and diverse over plateau-basin regions, yet their vertical structures remain unclear. Here, we develop and apply a physical-constrained framework to identify terrain-driven circulations over the Tibetan Plateau-Sichuan Basin and quantify their intensity, spatial extent, and central height. Three typical local circulations including one-cell, two-cell, and three-cell circulations are detected, which become more frequent while spatial extent shrinks.

Short summary
The Twain-Hu Basin in central China has extreme heat and severe ozone, yet few combined events. We show that basin O₃ is driven by synoptic transport from upwind sources rather than local heat, with the O₃ peak shifting to September, decoupling ozone from temperature. This pattern may be common in multi-source receptor basins.

The atmosphere’s ability to remove pollutants and greenhouse gases is largely controlled by the hydroxyl radical, but the causes of its long-term changes remain uncertain. Using a global atmospheric model, we quantified the effects of emissions, weather, and key chemical processes on hydroxyl radical levels between 2000 and 2017. Our findings improve understanding of atmospheric self-cleansing and help reduce uncertainties in future climate assessments.

Using satellite and comprehensive ground-based observations, we identify pronounced ice-cloud activation associated with transported exogenous aerosols. Under different large-scale atmospheric circulation regimes, ice-phase cloud activated over Mount Qomolangma (MQ) can be efficiently transported downstream through distinct pathways, exerting a pronounced ice crystal seeding effect on cloud–precipitation conversion.

Cloud water shapes rain and climate, and droplets can stay liquid even below freezing, but differences between warm and supercooled clouds remain unclear. We analysed aircraft observations and used machine learning to identify the controls. The cold clouds were deeper but held less water. Wind was the main control in both, while temperature mattered mainly through its interaction with wind rather than on its own. This should help improve weather and climate models.

We investigate the spatiotemporal distribution of springtime tropopause folds over the Arctic during 2000–2023 using ERA5 reanalysis data and a three-dimensional tropopause fold labeling algorithm. The study combines pan-Arctic spatial statistics with station-based analyses at Alert, Barrow, Villum, and Zeppelin, providing a climatological characterization of Arctic tropopause fold occurrence, depth dependence, seasonal evolution, and associated upper-tropospheric dynamical background.

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.

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.

1. The formation of ice crystal clouds catalyzed by dust aerosols were observed by coherent Doppler wind lidar in the Taklimakan Desert. 2. The wind provides a dynamic basis for the formation of ice crystal clouds and plays an important role in the decomposition process. 3. The special basin topography, turbulence and downdrafts keep the base height of the ice crystal clouds at around 3 km.

This study provides a high-resolution (0.25°, hourly) tropopause folding dataset for China (2014–2023) using ERA5 (ECMWF Reanalysis version 5) reanalysis data and a three-dimensional labeling method. It fills a critical data gap, enabling detailed spatiotemporal analysis of tropopause folding events. This validated resource provides a solid foundation for investigating stratosphere-troposphere transport and its impacts on near-surface air quality and extreme weather.

We conducted a year-long study in Nanjing to understand how tiny airborne particles take up water, which affects air quality and climate. We found that particle water uptake varies by season and size, with lower values in summer due to more organic materials. Local pollution mainly influences smaller particles, while larger ones are shaped by air mass transport. These findings help improve climate models and support better air pollution control in fast-growing cities.

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.

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.

The cold downhill airflow of the Tibetan Plateau leading to the low-level jet weakens the height and intensity of the inversion layer, which reduces the energy demand for the broken inversion layer. The low-level jet causes dust aerosols to accumulate near the ground. The material conditions for the development of the desert atmospheric boundary layer can be quickly transformed into thermal conditions.

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.

Based on long-term observational, reanalysis, and numerical model simulation datasets from 1901 through 2014, this study shows that precipitation over the East Asian monsoon boundary zone featured prominent interdecadal changes, with dry summers during the periods preceding 1927, 1939–1945, 1968–1982, and 1998–2010 and wet summers during 1928–1938, 1946–1967, and 2011 onwards. The Indian Ocean basin mode is an important oceanic modulator responsible for its interdecadal variations.

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.

We made mobile MAX-DOAS measurements in the background atmosphere over the Tibetan Plateau in summer 2021. We retrieved the tropospheric NO2 and HCHO vertical column densities (VCDs) along extended driving routes and found a decreasing trend of the VCDs with altitude. Elevated NO2 VCDs along the driving routes could be attributed to enhanced traffic emissions from the towns crossed. The spatio-temporal distribution of the HCHO VCDs correlated strongly with the surface temperature.

The convective updrafts near the sea-breeze fronts (SBFs) play important roles in initiating deep convection, but their characteristics are not well understood. By performing large-eddy simulations, we explain why the updrafts near the SBF are larger than but have similar strength to the updrafts ahead of the SBF. The results should also apply to other boundary-layer convergence zones similar to the SBF.

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.

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 also block low-level moisture transport, reshaping precipitation patterns.
