Summary: This article summarizes and compares 20 Holocene lacustrine carbonate δ^18O records from lakes across the Tibetan Plateau and investigates the factors and trends of hydroclimate variations. The study finds that long-term variations of lake δ^18O records are primarily influenced by moisture sources, and different regions show distinct trends in variations.

Summary: The Tibetan Plateau has undergone a moistening process since the late 1990s, but the southern part has experienced decreased summer monsoon precipitation and shrinking lakes. The precipitation changes in the southern Tibetan Plateau exhibit a decadal variation associated with a large-scale dipolar sea surface temperature pattern between the equatorial central Pacific and the Indo-Pacific warm pool.

Summary: An increasing trend in precipitation on the Tibetan Plateau (TP), particularly in the southeastern region (TPSE), has drawn attention from scientists. The Indian summer monsoon (ISM) plays a crucial role as a moisture source for TPSE. This study analyzes the ISM activities and varied moisture sources, and finds that the ISM in TPSE has a later onset, earlier retreat, shorter duration, and weaker intensity. There is a decreasing (increasing) precipitation trend in TPSE during the periods of 1979-2018 and 1999-2018 (1979-1998). The ISM activities impact the percentages of ISM moistures, affecting precipitation amount and trends in TPSE. These findings are important for studies related to hydrology, ecology, and paleoclimate reconstructions in TP.

Summary: The Tibetan Plateau vortices are the major precipitation-producing weather systems on the plateau, with a more significant impact in the warm season but also important in certain regions during the cold season. The interannual variation of vortices and associated precipitation is mainly determined by the number of vortices, while the heating anomaly caused by the Tibetan Plateau thermodynamic effect is also a significant factor.

Summary: This study investigated the influence of the Indian monsoon on the diversity, taxonomic composition, and community structure of airborne bacteria over glaciers in the Tibetan Plateau. The results showed that the Indian monsoon increased the airborne bacterial diversity and influenced the abundance of specific bacterial phyla. Additionally, the Indian monsoon altered the community structure of airborne bacteria and increased the presence of potential pathogens.

Summary: By using historical atmospheric circulation-precipitation relationships to constrain future simulated wet-season precipitation on the Tibetan Plateau, the study shows that constrained precipitation reduces spread and increases to only half of those in the unconstrained ensemble. Projected runoff is estimated to increase by 1.0-7.2% at the end of the twenty-first century due to global warming, affecting populations differently across basins and necessitating improved water security through climate change adaptation policies.

Summary: High-resolution hydroclimate records from a stalagmite in Rige Cave on the southeastern Tibetan Plateau provide insights into the hydroclimate variability and its global teleconnection. The records reveal the control factors of precipitation isotopes and the covariation between ISM rainfall and biomass change during the Younger Dryas. Prominent ISM events are identified, and a solar de Vries cycle is suggested to trigger the centennial-scale climate variations.

Summary: This study investigates the impact of the interannual variation of Tibetan Plateau-Indian Ocean thermal contrast on southern TP precipitation in May and its changes in the mid-1990s. It is found that the southern TP precipitation is closely related to the TP-Indian Ocean thermal contrast, which could be represented by a thermal contrast index (TCI). The analysis reveals that the southern TP precipitation in May increases significantly after 1996. Meanwhile, the TCI also enhances notably.

Summary: This study used stable isotopes to investigate the spatiotemporal patterns of water sources for Faber's fir in a high-altitude elevational gradient on the Tibetan Plateau. The results showed that the dependence on water sources varied with elevation, and precipitation contributed significantly to xylem water.

Summary: This study investigates the characteristics of water vapor transport across the southern boundaries of the Tibetan Plateau and its impacts on TP precipitation during the Indian summer monsoon. The results show that the precipitation in the strong ISM months is larger than in the normal months on boundaries B7, B8, and B9, while it is smaller in the weak ISM months. The afternoon precipitation difference between strong and weak ISM months shows a dependency on the water vapor transport of B8 and B10, and the water vapor transport of B9 also contributes to the increased afternoon precipitation.

Summary: The Tibetan Plateau plays a crucial role in the atmospheric circulation, and has experienced significant climate warming and wetting over the past half century. This study examines the wetting and drying of the plateau using soil moisture droughts, and finds that there have been frequent and severe droughts in certain regions. However, there was a significant alleviation of droughts in the interior and central-west TP in the middle to late 1990s, indicating a shift to a wetter climate. This wetting shift was mainly driven by precipitation over potential evapotranspiration, with the influence of the Atlantic multi-decadal oscillation.

Summary: Previous studies have shown that the South Asia monsoon contributes most moisture to the southern Tibetan Plateau, while the westerlies supply moisture to the Northern Tibetan Plateau. However, the sources of moisture for extreme precipitation events were unclear. In this study, external moisture sources were tracked for extreme precipitation events in the Northern Tibetan Plateau from 2010 to 2018. It was found that the South Asia monsoon is the main source of external moisture, except for the easternmost subregion where East Asia contributes the most. The westerlies are the second source of moisture for the western Northern Tibetan Plateau. Additionally, more than 40% of extreme precipitation events in the Northern Tibetan Plateau occur under the interaction of weak westerlies and enhanced South Asia monsoon, and these events have a longer duration.

Summary: Tracking and quantifying moisture sources in different drainage basins on the Tibetan Plateau reveals characteristics of the hydrological cycle and mechanisms of water resource changes. The study finds that moisture sources differ in their east-west and north-south extensions, with monsoons and westerlies playing significant roles. Terrestrial moisture dominates in all sub-basins, particularly in the upper Tarim River and Qaidam Basin.

Summary: Based on the CMIP6 models, this study investigates the historical and projected relationships between the Tibetan Plateau summer monsoon (TPSM) and precipitation in Central Asia (CA). The results show large uncertainties in simulating the TPSM-CA precipitation relationships and their dynamic processes. Regression analysis suggests that the selected models will still simulate a positive correlation between TPSM and CA precipitation in the second half of the 21st century, but with a shrinking significant area of correlations due to rising emission scenarios. In SSP1-2.6 and SSP2-4.5 experiments, the models indicate a strengthening TPSM and increased summer precipitation in the key region of CA.

Summary: This study investigates the impact of Tibetan Plateau vortex (TPV) on extreme precipitation events (EPEs) using TPV and precipitation datasets. The results show that TPV has a significant positive contribution to EPEs. EPEs tend to occur near the center and the southeastern quadrant of TPV. The structure and circulation of TPVs associated with EPEs are significantly different from those without EPEs.
