Summary: This study investigates the climatology and long-term variations of the diurnal cycle of total cloud cover (DCTCC) over the Tibetan Plateau (TP) using satellite observations and reanalysis datasets. The results show that the DCTCC follows a sinusoidal-like unimodal diurnal cycle and has decreased over the years. The peak time of the diurnal cycle has also shifted and the cycle has become narrower and steeper. Various meteorological factors, such as temperature, wind speed, moisture flux and relative humidity, are found to be significantly correlated with the DCTCC.

Summary: By combining Landsat imagery with deep learning, we have quantified the spatio-temporal changes of wetlands on the Tibetan Plateau from 1990 to 2019. Our findings show that the areal extent of wetlands has increased by 31.2% over the past 30 years, with a particularly noticeable growth of 22.5% during 2015-2019. This rapid expansion is primarily associated with increasing rainfall and temperature, which have varying influences on wetland changes across the plateau.

Summary: The precipitation changes over the Tibetan Plateau greatly affect the water resources of surrounding countries. This study investigates the role of anthropogenic forcing in these changes and identifies the contributions of thermodynamic and dynamic terms of vertical moisture advection. The results show that human-induced warming increases specific humidity over the Plateau and leads to a southward shift of the Asian westerly jet, favoring more precipitation over the north but less over the south. This research provides evidence of the importance of anthropogenic forcing on water cycle changes over the Tibetan Plateau.

Summary: The study focuses on the formation of river terraces in the northeastern Tibetan Plateau and their relationship with climate change and surface uplift. Using multiple dating methods, the researchers date the terrace sequence of the Datong River and find that it formed due to the combined effects of Asian monsoon enhancement and regional uplift. A detailed comparison between the Datong River and Yellow River in the Lanzhou Basin shows that the Datong River created more terraces, indicating its greater sensitivity to climate change compared to the larger Yellow River.

Summary: The study compared the soil acidification risk in the Tibetan Plateau (TP) with the Mongolia Plateau (MP) from 1980 to 2019, finding that the TP had lower cumulative acid input. The TP was less acid-sensitive overall compared to the MP, but the southeastern region was identified as highly susceptible to acidification due to low soil exchangeable base cation levels and higher acid input concentrations. Control of atmospheric acid deposition, especially sulfur deposition, is recommended for ecosystem sustainability in the southeastern TP.

Summary: The applicability of snow remote sensing data on the Tibetan Plateau is limited due to its unique characteristics of thin snow depth and high frequency of change. In this study, five commonly used snow remote sensing data were evaluated and integrated to develop a multi-source data fusion snow cover dataset for the Tibetan Plateau. The analysis showed that the snow cover days on the plateau are influenced by both the longest snow cover duration (SCD) and the short-term snow cycles. Significant decreases in snow cover days were observed in the southeast, while significant increases were observed in the northwest. This contrasting change in the snowpack poses new challenges to water resource management in the region.

Summary: This review examines the impacts of climate change and human activities on grasslands in the Qinghai-Tibetan Plateau. It discusses the changes in vegetation and soil, as well as the drivers behind these changes. The study finds that rising temperatures have been key in driving vegetation increases, while intense livestock grazing has caused grassland degradation. Effective restoration can be achieved through management policies and adaptive management, leading to improvements in net primary production.

Summary: This study collected PM2.5 samples in the northern piedmont of the Qinling Mountains and Xi'an, and analyzed the optical properties and radiation effects of water extracts. The results showed that the mass absorption efficiency (MAE365) of water-soluble organic carbon (WSOC) in the northern piedmont of the Qinling Mountains and Xi'an were 0.18 +/- 0.03 m2 g-1 and 0.78 +/- 0.96 m2 g-1, respectively. The relative light absorption of WSOC to elemental carbon (EC) was 6.76% and 33.41% in the northern piedmont of the Qinling Mountains and Xi'an. The chromophores in WSOC were mainly composed of humic-like and protein-like substances, with a higher proportion of humic-like substances. This research is of great significance to assess the interaction and influence between the city and the northern piedmont of the Qinling Mountains, as well as improve the capability of air pollution prevention and control of the Guanzhong Basin.

Summary: This study investigates the characteristics of hydro-meteorological factors and their influence on water and heat exchanges over alpine wetland. It is found that latent heat flux and thermal roughness length are higher in the warm season compared to the cold season, with a frozen depth of 20-40 cm. The transfers of heat fluxes are mainly controlled by longwave radiation and air temperature, and affected by root distribution. This research provides valuable insights for understanding land surface processes and wetland protection.

Summary: This study investigates the influence of carbonaceous aerosols on the extraction of organic carbon (OC) and black carbon (BC) in the Tibetan Plateau (TP). The results show that carbonaceous aerosols from different sources can affect the extraction efficiency of OC, leading to a reduction in the overestimation of BC concentrations. After considering this effect, actual BC concentrations at different sites on the TP were found to be lower than previously estimated, suggesting a lower warming effect caused by BC in this region.

Summary: Ground-based observations of atmosphere aerosols over Central Asia are limited. This study investigated the aerosol characteristics over Issyk-Kul, Kyrgyzstan, a background site in Central Asia, using long-term data collected with a sunphotometer. The study found that the aerosol optical depth and Angstrom exponent varied with seasons, with the highest values observed in spring. The dominant aerosol types were clean continental aerosols, followed by mixed aerosols, clean marine aerosols, dust, and urban/industrial and biomass burning aerosols. The aerosol volume size distribution indicated the influence of both anthropogenic and natural aerosols, with the coarse mode dominating during spring. Local and regional sources, as well as long-range transport, contributed to the aerosol over the background site.

Summary: Black carbon (BC) is a significant factor in climate warming and glacier melting in remote high mountains and polar regions.I t is commonly believed that BC emissions are the main cause of BC flux variation in remote regions. However, a comprehensive investigation of BC temporal variations using ice cores from the Himalayas reveals that contributions from dust storms and precipitation also play an important role (up to 56%) in regulating BC deposition flux and concentrations. Therefore, it is essential to consider not only BC emissions but also the influence of precipitation and BC transported by dust storms in order to accurately assess the lifetime, behavior, and climatic effects of BC in remote Himalayan glaciers.

Summary: This study investigates the longitudinal distribution of thermospheric density at dawn and dusk using data collected by the Chinese satellite APOD. The results show significant longitudinal variations in the thermospheric density, with the highest values near the geomagnetic pole in the winter hemisphere. Aurora heating and meridional wind are believed to contribute to these variations. Comparisons with the MSIS 2.0 atmospheric model demonstrate similar longitudinal variations, suggesting a relationship with the distribution of average atmospheric molecular weight. More observational data are needed to confirm these findings.
