ABSTRACT The Tibetan Plateau (TP), often referred to as the Water Tower of Asia and Third Pole, is undergoing rapid warming wetting, making it a key focus contemporary Earth System Science Research. Three Coordinated Regional Downscaling Experiment (CORDEX) domains: CORDEX‐EAS‐II, CORDEX‐CAS‐II CORDEX‐SAS‐II, overlap over TP, providing an opportunity assess sensitivity CORDEX simulations domain choice in this region. In study, we analyse similarities differences latest version Model (REMO) simulation across three domains at spatial resolution 25 km, focusing on climatology climate extremes. results show that has minimal impact REMO's extreme TP. Three‐dimensional indicators reveal primarily influences temporal evolution for temperature with effects magnitudes patterns. For precipitation simulations, more pronounced effect than variation or Additionally, significant seasonal biases are observed wet days, negative summer linked lower frequency 1–7 mm precipitation, while positive other seasons associated overestimation moderate‐to‐heavy rainfall frequencies.

Abstract Precipitation events can effect temperature and modulate its response to climate change, yet the impact of sub‐daily precipitation on extremes in China has been understudied. This study therefore focuses daily maximum ( T max ) minimum min across China's climatic regions from 1952 2019. Results show that precipitation‐induced cooling effects through cloud evaporative cooling, particularly arid semi‐humid regions. In regions, enhances increased downward longwave radiation changes soil thermodynamics, while humid rainfall‐induced suppresses . Notably, warming trend during rainy weathers lacks statistical significance consistently warms more dry conditions. These findings reveal a saturation provide framework for understanding precipitation‐temperature interactions, with implications refining model assessing global warming.

Abstract Cloud microphysical properties play a crucial role in stratus cloud behavior, with notable differences between precipitating and non‐precipitating parts. This study presents aircraft‐based observations on 8 May 2020 over coastal region China, to investigate the characteristics of liquid cloud. Significant aerosols number concentration ( N ), droplet c drizzle d ) are observed, lower concentrations part for all three. The effective radius r e droplets is smaller, while exhibit larger part. In part, decreases altitude, it remains constant due falling out. Aerosol size distribution analysis implies that precipitation mainly scavenges sizes smaller than 0.3 μm. particle distributions bimodal, broader spectrum especially layers. Additionally, drizzles contribute approximately 20% total water content 70% Our findings highlight distinct parts, playing critical microphysics formation.

Abstract The impact of air pollution control programs on the vertical structure precipitation remains poorly understood. Using multiple data sources, we observed a yearly decrease in aerosol optical depth (AOD) southern China from 2014 to 2019, probably due these programs. In contrast, top height related rain onset (PTH 0 ), increased annually after accounting for thermodynamic variations. Further analyses revealed that, within mixed/lower atmospheric layers, growth precipitating particles (SlopeA/SlopeB) was significantly faster/slower compared subsequent years. correlation coefficients ( R ) between AOD and SlopeA PTH were 0.99 −0.94, respectively. As this study is based multi‐source observations, further research incorporating model simulations necessary elucidate mechanisms underlying emission reductions precipitation.

Abstract Climate models commonly overestimate warm rain frequency and underestimate its intensity over the ocean, primarily due to insufficient representation of aerosol effects. This pertains both fine aerosols (FA) coarse sea spray (CSA), where latter is mostly absent in models. Here, our observations show that adding CSA enhances vertical structure, contrast effect FA. The magnitude larger than opposite For with top heights 2–3 km, raindrop size, concentration, rate can be increased by factors 1.03, 1.47, 1.60, respectively. These CSA-induced changes are for thicker clouds, reaching a maximum 1.12, 1.85, 2.21, Therefore, combined FA effects should incorporated into climate accurately simulated precipitation microphysical processes.

An eight-year satellite observation dataset reveals that sulfate aerosols significantly influence the vertical structure of precipitation and latent heat (LH) in Beijing-Tianjin-Hebei (BTH) region during summer. In this period, prevalent combine with warm, humid southerly winds elevated convective available potential energy (CAPE), influencing dynamics. Under polluted conditions specific CAPE top temperature (PTT) ranges, particles experience accelerated growth within mixed-phase layer, delineated by −5 °C to 2 isotherms, compared pristine environments. This results a marked increase both intensity height at which maximum LH is released. Subsequent analysis hygroscopic aerosols, acting as cloud condensation nuclei (CCN), amplify collision-coalescence process mixed layer amid high water content, propelling rapid particle elevating PTT. warming effect surpasses cooling contribution from robust CAPE, culminating net elevation PTT under scenarios ones. Additionally, quantification sensitivity aerosol optical depth (AOD) unveils consistency between satellite-detected responses those predicted cloud-resolving model simulations. The study deduces role CCN either invigorating or diminishing contingent on water.
