Abstract Despite the importance of precipitation and moisture transport over Tibetan Plateau for glacier mass balance, river runoff local ecology, changes in these quantities remain highly uncertain poorly understood. Here we use observational data model simulations to explore close relationship between summer rainfall variability southwestern (SWTP) that central-eastern India (CEI), which exists despite separation two regions by Himalayas. We show this is maintained primarily ‘up-and-over’...
ABSTRACT Glacier area changes on the Tibetan Plateau were studied in different drainage basins based Landsat satellite images from three epochs: 263 mid-1970s, 150 1999–2002 and 148 2013/14. Three mosaics (M1976, M2001 M2013) with minimal cloud snow cover constructed, uncertainty due to each epoch having a finite span was accounted for. outlines (TPG1976, TPG2001 TPG2013) digitized manually guidance SRTM DEM v4.1 Google Earth imagery. To achieve complete multi-temporal coverage reasonable...
ABSTRACT Understanding variations in isotopic composition of precipitation from monsoon regions is crucial for its utilization paleoclimate studies. This study explores the relationship between δ18O data East Asian (EAM) region archived Global Network Isotopes Precipitation (GNIP) and cloud ISCCP their linkage with large-scale atmospheric circulation patterns. Results show that are significantly positively correlated cloud-top pressure (CTP) on both local regional scales. Mechanically...
Abstract Snow and frozen soil are important factors that influence terrestrial water energy balances through snowpack accumulation melt freeze‐thaw. In this study, a new land surface model (LSM) with coupled snow physics was developed based on hydrologically improved LSM (HydroSiB2). First, an energy‐balance‐based three‐layer incorporated into HydroSiB2 (hereafter HydroSiB2‐S) to provide description of the internal processes pack. Second, universal simplified HydroSiB2‐S depict freezing...
ABSTRACT Based on 20‐year (1985–2004) records of surface‐air‐temperature at 16 stations between the elevations 3553 m and 4801 a.s.l. in southeastern Tibetan Plateau (or northern slopes eastern Himalayas), this paper examines monthly, seasonal annual characteristics near‐surface temperature lapse rates (TLRs). A linear regression model was fitted for rate calculation. The cycle TLR shows a distinct pattern, i.e. steepest winter shallowest summer. Results are partially consistent with those...
Glaciers in the upper Indus supply more than half of river water, are experiencing significant melting with a debated fate. The recent rate is still contained by considerable uncertainties, hindering to estimate precise glacier mass change. Here we present geodetic balance results for whole Basin using SRTM and ALOS 30 m elevation data, improved inventory, optimized surface density, validation through in-situ differential GPS ICESat data. Our inventory derived improving RGI6.0 boundaries...
Abstract. This study integrated a water isotope module into the hydrological model THREW (Tsinghua Representative Elementary Watershed) which has been successfully used in high and cold regions. Signatures of oxygen stable (18O) different inputs stores were simulated coupling with simulations runoff generation. Isotope measurements precipitation samples assumed constant signature ice meltwater to force module. signatures such as snowpack subsurface updated by an completely mixing procedure....
Many have made efforts to clarify the climatic significance of stable isotopic variations in ice cores around central Asia through study isotopes present‐day precipitation. A new shallow core from Muztagata, eastern Pamirs, allows for a detailed comparison annual δ 18 O variation with local meteorological data as well global air temperature variations. On basis seasonal fluctuations precipitation, 41.6‐m drilled at 7010 m provides record about one‐half century. The this are good agreement...
Abstract Measurements of precipitation isotopic composition have been conducted on a daily basis for 1 yr at Bomi, in the southeast Tibetan Plateau, an area affected by interaction southwest monsoon, westerlies, and high pressure systems, as well Lhasa, situated west Bomi. The measured isotope signals are analyzed both event seasonal scale using available meteorological information airmass trajectories. processes driving variability investigated multidecadal climate simulations forced...
Abstract The numerous lakes on the Tibetan Plateau play an important role in regional hydrological cycle and water resources, but systematic observations of lake balance are scarce Plateau. Here, we present a detailed study Cona Lake, at headwaters Nujiang‐Salween River, based 3 years (2011–2013) δ 18 O 2 H, including samples from precipitation, water, outlet surface water. Short‐term atmospheric vapor was also sampled for isotope analyses. H–δ relationship (δ H = 6.67δ − 20.37) differed...
Abstract Quantifying the transpiration fraction of evapotranspiration ( T / ET ) is crucial for understanding plant functionality in ecosystem water cycles, land‐atmosphere interactions, and global budget. However, controls mechanisms underlying temporal change remain poorly understood arid semiarid areas, especially remote regions with sparse observations such as Tibetan Plateau (TP). In this study, we used combined high‐frequency laser spectroscopy chamber methods to constrain estimates an...

Abstract. Issues related to large uncertainty and parameter equifinality have posed big challenges for hydrological modeling in cold regions where runoff generation processes are particularly complicated. Tracer-aided models that integrate the transportation fractionation of water stable isotope increasingly used constrain refine parameterizations specific regions. However, common unavailability site sampling spatially distributed precipitation isotopes hampers practical applications...
Precipitation samples were collected in a large-scale region (more than 2,000 km from the north to south of Tibetan Plateau) and middle scale (with an area about 9,000 km2) Plateau study impact monsoon precipitation on stable isotopes. In region, river water at several stations along Qinghai-Tibet Highway plateau. Results show that Indian not only influences spatial variation isotope precipitation, but also relationship between δ18O δD. Deuterium excees (d) areas where is directly controlled...
Abstract The mass balance of the Xiao (Lesser) Dongkemadi Glacier located in Tanggula Mountains, central Qinghai‐Tibetan Plateau has been monitored since 1989. results show that glacier recently shown a deficit trend, and glacial terminus was also retreating. Positive dominant during period 1989–1993, accumulated reached 970 mm. However, negative occurred 1994, except for large positive year 1997. − 701 mm 1998, an extremely year. equilibrium line altitude showed significant increasing...
