Abstract Evapotranspiration ( ET ) is a crucial component of the hydrological cycle in terrestrial ecosystems, but estimating mountainous regions challenging. In this study, performance generalized nonlinear formulation complementary principle while daily was evaluated, and spatial‐temporal variation analyzed across four vegetation types along an elevation gradient on Mount Gongga, Southwest China. The values calibrated Priestley Taylor coefficients for each sites ranged from 0.98 to 1.13....
Abstract Permafrost thawing over the Tibetan Plateau (TP) is a consequence of climatic warming, which will change local hydrological processes remarkably. Evapotranspiration (ET) an important process indicator that needs to be well quantified. Several methods have been applied estimate ET. However, energy consumed by was neglected in ET estimation on TP. Here simple but effective method introduced represent consumption due ice phase changes generalized nonlinear complementary principle. Our...
Climate-sensitive northern cryosphere inland waters emit greenhouse gases (GHGs) into the atmosphere, yet their total emissions remain poorly constrained. We present a data-driven synthesis of GHG from considering water body types, zones, and seasonality. find that annual are dominated by carbon dioxide ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline" overflow="scroll"> <mml:mrow> <mml:msubsup> <mml:mn>1149.2</mml:mn> <mml:mn>1004.8</mml:mn> <mml:mn>1307.5</mml:mn>...
Abstract Nodulating leguminous and actinorhizal N 2 ‐fixation pioneer plants are well‐known drivers of primary succession as they may facilitate soil development the growth neighbouring non‐nodulating plant species a result their ‐fixing capacity. However, recent studies have shown that some also obtain through endophytic diazotrophs, although capacity is relatively low when compared with traditionally nodulating species. There remains limited understanding how these two categories...
Abstract As a crucial variable in hydrological and climate modeling, lot of efforts have been made to estimate the evaporation ( E , including soil evaporation, canopy interception, plant transpiration) on Tibetan Plateau (TP). Most studies showed that TP stops increasing or even decreases recent two decades. However, spatio‐temporal variability this phenomenon its underlying mechanism remains uncertain. Here, we utilized state‐of‐the‐art version sigmoid generalized complementary equation...
Abstract To investigate the influences of land surface temperatures (LSTs) on suprapermafrost groundwater discharge, a river valley was selected in typical permafrost region Fenghuoshan (FHS) watershed central Qinghai‐Tibet Plateau. We developed two‐dimensional model to simulate seasonal dynamics controlled by LSTs and changing trends under warming climate scenario (3°C/100 year). calibrated key parameters our field observations at FHS analysed relationship between different discharge active...
Abstract Riverine dissolved inorganic carbon (DIC) exports play a central role in the regional and global cycles. Here, we investigated spatiotemporal variability sources of DIC eight catchments Yangtze River source region (YRSR) with variable permafrost coverage seasonally thawed active layers. The YRSR are DIC‐rich (averagely 25 mg C L −1 ) export 3.51 g m −2 yr DIC. seasonal changes temperature, layer, flow path, discharge can alter stable isotope ( δ 13 C‐DIC). most depleted C‐DIC values...
Abstract Water use efficiency (WUE) provides vital information about the carbon‐water coupling relationship of a terrestrial ecosystem. Understanding spatiotemporal variability and driving factors Tibetan Plateau (TP) WUE can facilitate prediction response process in TP to climate change. We used land surface model investigate changes responses environmental factors, such as atmospheric CO 2 concentration Our results suggest that average annual was 0.38 g C kg −1 H O this variable tended...
Abstract Energy partitioning and evapotranspiration (ET) of alpine meadows in permafrost areas are crucial for water cycle on the Qinghai-Tibet Plateau. However, seasonal (freeze–thaw cycle) variations energy ET their driving factors must be clarified. Therefore, 4-year fluxes [i.e. latent heat (LE) sensible (H)] were observed, bulk parameters surface conductance, decoupling coefficient (Ω), Priestley–Taylor (α)] estimated an meadow Mean daily LE (27.45 ± 23.89 W/m2) H (32.51 16.72 accounted...
The Qinghai-Tibet Plateau (QTP) is experiencing severe permafrost degradation, which can affect the hydrological and biogeochemical processes. Yet how change affects riverine carbon export remains uncertain. Here, we investigated seasonal variations of dissolved inorganic organic (DIC DOC) during flow seasons in a watershed located central QTP region. results showed that DIC concentrations (27.81 ± 9.75 mg L-1) were much higher than DOC (6.57 2.24 L-1). fluxes 3.95 0.94 g C m-2 year-1,...
Abstract Diverse meteorological and vegetation conditions at different elevations years lead to varied contributions of evapotranspiration (ET) water yield in montane areas. However, how physical biological factors affect interannual elevational ET fluctuations energy‐limited ecosystems remains unclear. Therefore, we quantified the spatial‐temporal patterns separated controls on using 5‐year (2015–2019) eddy‐covariance data perturbation analysis Mount Gongga, Southwest China. Coefficients...
Terrestrial ecosystems&#8217; response to atmospheric changes (e.g., CO&#8322; levels, vapor pressure deficit) and the redistribution of water on land has drawn significant attention in recent years. Understanding sources that trees utilize is critical for elucidating their adaptation strategies resilience as precipitation patterns seasonality shift a changing climate. Recent studies suggest primarily rely winter during summer Allen et al., 2019; Goldsmith 2022; Floriancic 2024)....
