Summary: The study on summertime atmospheric water vapor transport in the Tibetan Plateau and surrounding regions from 1990 to 2019 based on ERA5 reanalysis data revealed that the southern boundary is the main entry point for water vapor from low-latitude monsoon regions, with significant water vapor transport into regions like Sichuan Basin, TST and eastern boundary. The overall trend indicates that water vapor inflows into the Tibetan Plateau are greater than outflows, making it a water vapor sink during the summertime.

Summary: The effect of aerosol on liquid cloud microphysical properties over the Tibetan Plateau is studied, revealing distinct differences between the northern and southern regions. When the aerosol loading increases, the liquid cloud droplet effective radius increases in the northern region but decreases in the southern region. In addition, the influence of aerosol on liquid clouds is found to be dependent on different meteorological conditions and aerosol types in the two regions.

Summary: During the extreme warming period, surface temperatures in glacial regions of the Tibetan Plateau have increased faster than non-glacial areas, and the duration and intensity of glacier surface heatwaves have significantly increased. These changes may pose potential threats to the sustainability of glacier water resources and increase the risk of glacier related hazards.

Summary: The Tibetan Plateau (TP) experiences increasing precipitation trends in the northern region but not in the southern region, which is attributed to the activities of Tibetan Plateau vortices (TPVs). The significant warming over the TP influences the genesis frequency of TPVs differently in the north and south, leading to distinct precipitation trends in the two regions.

Summary: Soil moisture plays a crucial role in the climate system, and correcting spring soil moisture biases in the seasonal frozen-thawing zone (SFTZ) in the northern hemisphere can improve summer precipitation simulations. This correction significantly adjusts energy and moisture evolution on the land surface, reducing biases in sensible and latent heat fluxes in the summer. Furthermore, it helps correct geopotential height and water vapor transport biases, making spring soil moisture in the SFTZ a potential signal for predicting summer precipitation in the northern hemisphere.

Summary: A closed-cell marine stratocumulus case during the ACE-ENA aircraft field campaign was examined to study the heterogeneities of cloud and drizzle microphysical properties and the aerosol-cloud-precipitation interactions. Variabilities in cloud and drizzle microphysics were found in two different flight legs, with one leg close to adiabatic and the other sub-adiabatic. The sub-cloud precipitation rate and CCN loss rates were significantly higher in the sub-adiabatic leg, highlighting the importance of considering cloud and drizzle heterogeneities in assessing aerosol-cloud-precipitation interactions.

Summary: By comparing the effects of snow cover anomalies and frozen soil thawing anomalies, this study investigates the impact of the frozen soil thawing anomalies on precipitation in early summer over the Tibetan Plateau. The results show that delayed (advanced) frozen soil thawing induces distinct cold (warm) anomalies in soil temperature, weakening (enhancing) surface diabatic heating over the mideastern Tibetan Plateau. Compared to the albedo effect of snow cover anomalies, the impacts of frozen soil thawing anomalies on soil hydrothermal regime and surface diabatic heating can persist longer.

Summary: The fragile ecology of the Yellow River basin is vulnerable to global warming and human activities. This study analyzed the variations in vegetation cover in different climate zones of the Yellow River basin from 1982 to 2019. The results showed that temperature is the main driver of vegetation cover variations in the source region, while the middle and lower reaches are influenced by both temperature and precipitation-evaporation differences.

Summary: In this study, the warm-cloud physics parameterizations in the NCAR Community Atmospheric Model version 6 and 5 (SCAM6 and SCAM5) are evaluated using measurements from the ARM Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign. The results show that both SCAM6 and SCAM5 can simulate the structure and properties of marine boundary layer clouds, but they underestimate cloud liquid water content, cloud droplet size, and rain liquid water content while overestimating surface rainfall. The study emphasizes the importance of understanding biases in cloud physics parameterizations through combining single-column modeling with in situ observations.

Summary: This study investigated cloud phase and macrophysical properties over the Southern Ocean using meteorological measurements. The findings revealed key features of cloud cover, cloud types, and cloud layer temperatures. The study showed that the polar region had higher cloud cover, with low-level and deep convective clouds being the most common cloud types. Mixed-phase clouds were found to be more prevalent in the southern region. These findings are important for improving climate model simulations over the Southern Ocean.
