Summary: This paper addresses questions regarding the present deformation rate in the Tianshan Mountains by analyzing the deformation characteristics and movement rates of different fold-and-thrust belts using InSAR observations. The results show that the Tianshan Mountains exhibit different deformation features on the northern and southern margins, highlighting the potential of multi-temporal InSAR analysis.

Summary: This study utilized an extended Budyko framework to investigate the intra-annual variability of streamflow in forested mountain watersheds, identifying precipitation as the primary contributor to streamflow variability, with TWS also playing a significant role. Precipitation dominated streamflow variability in summer and autumn, while evapotranspiration and TWS had substantial impacts on streamflow in spring and winter.

Summary: The study found that vegetation belts at different altitudes respond differently to global climate change, with spatial differences in vegetation belt changes at low altitudes and consistent trends among altitude belts at high altitudes. Temperature is the main factor influencing the changes in altitudinal vegetation belts in the Tianshan Mountains, affecting the development of animal husbandry in different regions.

Summary: Understanding and managing mountain floods have become urgent due to global climate change and human activities exacerbating flood risk. However, research on floods in the Tianshan Mountains of China is still lacking. In this study, a customized set of flood research methods was used to analyze the frequency and magnitude of floods. It was found that floods in the Chinese Tianshan Mountains increased from 2014 to 2016 but then rapidly decreased. The variation in floods was primarily correlated with precipitation and snowmelt change. Additionally, atmospheric circulation anomalies and water vapor input were identified as contributing factors to the changes in precipitation and storm floods. It is projected that flood frequency will rebound in the future due to rising precipitation and temperature.

Summary: In this study, a composite multivariate drought index (CMDI) was developed by combining three univariate drought indices (SPI, SRI, and WSDI) and four timescales (monthly, quarterly, semi-annually, and annually) using a copula. The CMDI integrated information on terrestrial water storage, precipitation, and runoff to comprehensively assess drought trends and characteristics in 10 major basins in China from 2003 to 2020. The results showed an increasing trend of drought in the Qinghai-Tibet Plateau and North China Plain, with more severe drought in northern China than in southern China, as monitored by the CMDI.

Summary: The sea level in the Arctic remains uncertain, with disagreements between GRACE and satellite altimetry data. A study comparing different datasets found that the best agreement was reached using a combination of in-situ hydrographic data and altimetry products. However, a large residual signal was found in the East Siberian Sea, indicating uncertainties in satellite observations. Overall, caution is recommended when using satellite observations in the Arctic region to study sea level trends.

Summary: Understanding the role of reservoirs in the terrestrial water cycle is crucial for sustainable water resource management, especially in China where reservoirs are extensively built. However, the lack of continuous, long-term reservoir operation records and an accurate modeling tool have posed scientific challenges. In this study, a continental-scale land surface-hydrologic model is developed to explicitly represent 3,547 reservoirs in China and quantify their seasonal dynamics and role in terrestrial water storage.

Summary: Interannual variations in global mean sea level are closely correlated with the evolution of El Nino-Southern Oscillation, but differences occur in extreme El Ninos, primarily due to changes in barystatic heights. The 2015-2016 event developed with Central Pacific El Nino forcing, which contributed to a stronger negative anomaly of global terrestrial water storage. It is suggested that hydrology-related mechanisms of interannual variations in GMSL should be emphasized further.

Summary: This study focused on the Kunes River Basin in the western Tianshan Mountains, China, and used atmospheric meteorological data to analyze the climatic parameters, snow melt process, and major environmental controls. By constructing a subcanopy snowmelt model, the study found that the influence of net longwave radiation on the snowmelt process in the subcanopy is greater than that of net shortwave radiation. The study also highlighted the significant influence of water recession due to relatively high night-time temperatures in the subcanopy.

Summary: This study analyzed the spatiotemporal variations in water-use efficiency (WUE) and its correlations with climate factors and drought in the Tianshan Mountains (TMS). The results showed that annual net primary productivity (NPP) and evapotranspiration (ET) exhibited increasing trends while WUE showed the opposite tendency during the study period. Land-use types had significant effects on WUE, and there were spatial differences in the correlation between WUE and climate factors. This study provides important insights for understanding WUE variation and water resource management in the study area.

Summary: This study comprehensively and quantitatively summarizes the moisture sources of precipitation in the Tianshan Mountains, revealing that Central Asia is the main provider of moisture while direct contribution from the ocean is limited. The contribution varies among seasons and regions, but overall, continental sources play a dominant role.

Summary: This study proposes a new mathematical approach to downscale monthly terrestrial water storage anomalies from GRACE and estimates groundwater storage anomalies at a daily temporal resolution and a spatial resolution of 0.25 degrees x 0.25 degrees. The method combines GRACE gravity models and hydrological model outputs to enhance the quality of the estimated TWSA and GWSA. The results show significant correlations and low errors in the estimated GWSA compared to in-situ wells.

Summary: The study found that in the Shanmei Reservoir Basin, farmlands and orchards were the main sources of nitrogen, with fertilizer application being the key cause of riverine nitrogen output and retention within the basin. On average, 64% of anthropogenic nitrogen inputs were retained within the basin, while 36% of nitrogen was exported downstream and to coastal areas. Seasonal nitrogen retention was mainly influenced by rainfall and runoff.

Summary: Evapotranspiration (ETa) in the Minjiang River Basin was calculated using the Penman-Monteith equation and the dual crop coefficient method, and the applicability of GLDAS-Noah ETa data in the basin was evaluated. The results showed that ETa in the basin has been increasing since 2000, with a higher increase in winter and spring compared to summer and autumn. Annual air temperature had the largest effect on ETa, followed by precipitation. The study provides important insights into ETa variations in the basin under global warming.

Summary: Evaluation of gray water footprint (GWF) flow and its driving mechanism is crucial for tracing pollution sources and formulating responsibility-sharing strategies to alleviate water shortages. The study found that the changes in GWF in Fujian Province are mainly driven by per capita final demand and GWF outsourcing. The construction sector is most affected by driving forces, followed by machinery and equipment manufacturing, and other services. By assessing sectoral GWF flow and net inflow GWF caused by sector trading, this study provides a comprehensive understanding of sectoral pollution outsourcing.

Summary: Systematic analysis of daytime and nocturnal precipitation changes in China reveals an overall increase in precipitation, especially in the western regions. Significant climatological differences between daytime and nocturnal precipitation during summer were observed. The development of a Z index helped quantify the diurnal differences of precipitation, showing a negative annual trend with increasing differences seasonally, except for summer. The intensity of diurnal differences of precipitation has decreased in China since 1990.
