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...
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...
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 This study simulated the effects of changes in underlying surface induced by long‐term urbanization on trends air temperature (SAT) over three extensive urban agglomerations (Beijing‐Tianjin‐Hebei, BTH; Yangtze River Delta, YRD; and Pearl PRD) China during 1980–2009. To isolate continuous expansion SAT with least computation cost, we employed Community Land Model (CLM4.5) an off‐line mode for a relatively long period. Based high‐quality land use data set dating back to 1980s, two...
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 In this study, the spatiotemporal changes and driving factors of evapotranspiration (ET) over Tibetan Plateau (TP) are assessed from 1961 to 2014, based on a revised generalized nonlinear complementary (nonlinear-CR) model. The average annual ET TP was 328 mm. highest value (711 mm) found in forest region southeastern part TP, lowest (151 desert northwestern TP. terms contribution different subregions total amount for whole plateau, meadow steppe regions contributed most accounting...
Abstract Civic scientific literacy (CSL) is a fundamental indicator of social development and national very important for personal well-being competitiveness. To be in line with the technological advancements demands current era, we focused on “science engagement”, which now considered an approach to enhance CSL general public, developed 4-dimensional assessment framework based crucial elements citizens engage science. The 4 dimensions are knowledge (SK), method (SM), problem-solving (PS),...
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...
Alpine grasslands are the dominant vegetation of Tibetan Plateau (TP) and essential to understanding mechanism change in water use efficiency (WUE) high-cold ecosystems a changing environment. However, it is still unclear how WUE different alpine respond changes precipitation. Therefore, we investigated variations growing season its drivers among grassland types, including meadow permafrost (PAM), seasonal frost (SAM), steppe (PAS), (SAS), precipitation years. The mean was significantly...
Abstract The research on the trends of mountainous aridity and issue elevation‐dependent (EDA) has long been hindered by limitations in data validity. In this study, we present global monthly merged sets Vapor Pressure Deficit Aridity Index (AI) from 1960 to 2020, aiming detect attribute patterns atmospheric soil six representative high areas worldwide. Our findings reveal that most regions experienced significant aridification after 1970s ( p < 0.05). Rocky Mountains Ethiopian Highlands...
Abstract In this study, the spatiotemporal changes in net primary production (NPP) and drivers, including climate change, atmospheric CO 2 concentration land use over Tibetan Plateau from 1979 to 2016 were investigated using version 4.5 of Community Land Model. Based on high‐resolution forcing data, six numerical experiments designed assess relative contribution different environmental factors NPP. Our simulation results suggest that NPP has increased significantly at a rate 2.25 Tg C/year...
