Abstract Lake Hulun is the fifth‐largest lake in China, playing a substantial role maintaining balance of grassland ecosystem Mongolia Plateau, which crucial ecological barrier North China. To better understand changing characteristics and driving mechanisms, it necessary to investigate water storage changes on extended timescales. The main objective this study reconstruct time series over past century. We employed machine learning approach termed extreme gradient boosting tree (XGBoost)...
The Xiaoxingkai Lake Basin in China. Watershed hydrological simulation is a prominent aspect of hydrology, however, comprehensive analysis lake basins based on rarely conducted. Therefore, we used the Soil and Water Assessment Tool (SWAT+) with dynamic land use/land cover (LULC) input time-varying parameters to simulate streamflow estimate impacts LULC climate change during 1961–2017. We also evaluated contributions water volume through balance analysis. simulated agrees well observations at...
It is well known that the spatial and temporal patterns in streamflow can be correlated with many teleconnections, e.g., solar activity climatic phenomena such as El Niño. However, fewer studies have attempted to analyze both influence of large scale on natural processes, particularly hydrological processes. In this study we examine long term records Niño for their combined across southern Canada. Data used analysis include sunspot number, sea surface temperature anomaly region 3.4, annual...
Abstract In this study, micrometeorological observations in a shrub ecosystem and an adjacent poplar plantation forest the Kubuqi Desert, Inner Mongolia, China, are used to evaluate theory of intrinsic biophysical mechanism (IBPM) investigate effects afforestation. Results indicate that after forcing energy balance closure observed fluxes, IBPM agrees very well with temporal variations surface temperature difference between paired sites at half‐hourly time scale. Afforestation activity...
Abstract The northeastern Tibetan Plateau is located in a climatic junction, which considered an ideal region to explore the interactions between summer monsoons and westerly circulation patterns. However, date, needed long-term precipitation-based isotopic dataset too limited predict This paper presents evaluation of hydrometeorological processes climate dynamics based on 7-yr precipitation isotope covering monsoon periods from 2012 2018. Results illustrated remarkable seasonal variability,...
A climate transition towards warm–wet conditions in Northwest China has drawn much attention. With continuous change and universal glacier degradation, increasing water-related hazards vulnerability have become one of the important problems facing Tarim Basin. However, impacts on streamflow abrupt extreme hydrological events were less discussed, especially glacial basins. In present study, discharge datasets four basins Basin from 1979 to 2018 constructed using GRU-GSWAT+ model first. The...

Abstract Stable water isotopes (δ 18 O and δ 2 H) are an important source signature for understanding the hydrological cycle altered climate regimes. However, mechanisms underlying atmospheric vapour in northeast Qinghai‐Tibetan Plateau of central Asia remain poorly understood. This study initially investigated isotopic composition its controls during premonsoon monsoon seasons. Isotopic compositions precipitation exhibited high variability across seasons, with most negative average values...
Abstract Uncertainty analysis is an integral part of hydrological modelling. We investigated uncertainty from model structure and parameters in the soil water assessment tool (SWAT) hydrologic simulations for a Canadian Shield catchment (5.4 km 2 ) south central Ontario. influences on parameter identifiability prediction by comparing performance SWAT (version 2009.10.1 Beta3) SWAT‐CS (a version representing processes catchments). Equifinality was found to exist many process modules snow...
Abstract Indirect nitrous oxide (N 2 O) emissions from drainage ditches and headwater streams are poorly constrained. Few studies have monitored stream N O fewer modeling been conducted to simulate emissions. In this study, we developed direct indirect emission modules a corresponding calibration module for use in the Soil Water Assessment Tool (SWAT) model, implemented expanded SWAT model (termed SWAT‐N representative fourth‐stream‐order catchment (210 km ) six first‐order catchments...
Qinghai Lake Basin (QLB), the largest saline lake in China and its collecting basin Climate change has caused clear shrinkage or dramatic water level fluctuation of lakes arid semi-arid regions, while underlain mechanisms remain unclear. The joint lake-basin investigations (spatial) long-term studies (temporal) are urgently needed. This study developed SWAT+ to jointly simulate cycle QLB investigated how hydrological regime changed at hundred-year scale. modeling framework consisted revised...
ABSTRACT Rapid warming in northern lands has led to increased ecosystem carbon uptake. It remains unclear, however, whether and how the beneficial effects of on uptake will continue with climate change. Moreover, role played by water stress temperature control highly uncertain. Here, we systematically explored trend gross primary production (measured “ S GPP‐TAS ”) across (> 15°N) using a standardized multiple regression approach controlling other covarying factors. We estimated three...
