With the rapid development of technologies such as big data and cloud computing, communication computing in form exponential growth have led to a large amount energy consumption centers. Globally, centers will become world’s largest users consumption, with ratio rising from 3% 2017 4.5% 2025. Due its unique climate energy-saving advantages, high-latitude area Pan-Arctic region has gradually hotspot for center site selection recent years. In order predict analyze future carbon emissions...

Meteorological droughts triggered by relative precipitation deficits would propagate through ecohydrological processes and result in comprehensive drought events terrestrial ecosystems. Drought indices indicating integrated information from perspective are essential for monitoring assessment. Considering processes, Copula modeling was utilized to develop an ecological index (ECDI) that included key elements as precipitation, actual evapotranspiration, soil moisture, gross primary production....

Groundwater drought is distinctive comparing with other droughts, featuring high concealment, long duration, and obvious hysteresis. It may have significant negative effects on agriculture, eco-environment, social economy sectors. Therefore, investigating the temporal spatial characteristics of groundwater its driving factors meaningful for monitoring assessing risks shortage. In this study, a index based storage anomalies (GWSAs) derived from GRACE satellites was developed to detect analyze...

Understanding the response of vegetation spring phenology to climatic factors in arid regions is crucial for projecting land-climate interactions ecosystems under climate change. The Xinjiang region, an important part northern China with complex features, was selected as a case study. We investigated impact temperature, precipitation, and solar radiation on start growing season (SOS) using long-term series normalized difference index, data from 1982 2014, partial least squares regression...

Abstract. Understanding the changes in near-surface wind speed (NSWS) is crucial for weather extremes and energy management. This study examines response of NSWS to atmospheric carbon dioxide (CO2) removal using large ensemble simulations Carbon Dioxide Removal Model Intercomparison Project models. Our results indicate that increasing CO2 levels lead an overall reduction Northern Hemisphere (NH) extratropical over land. Subsequent during early ramp-down period rapidly restores NH NSWS....

The characteristics of the drought propagation from meteorological (MD) to agricultural (AD) differ in various climatic and underlying surface conditions. However, how these factors affect process is still unclear. In this study, influencing were investigated an arid region Northeast Asia (ARNA) during 1982–2014. Based on run theory, detected using standardized precipitation index (SPI) soil moisture (SMI), respectively. time MD AD was investigated, influence identified. Results demonstrated...

Natural ecosystems of the West Liao River basin (WLRB) in northeast China have been damaged by both natural and human factors from 1990s. Since 2000, China’s Grain-for-Green Program (GFGP) has widely adopted with aim improving ecosystem services. An accurate evaluation eco-hydrological effects for policy implementation is essential to provide references further restoration This study quantified characterized services their trade-offs/synergies using models statistical methods WLRB 1990 2020....

Abstract Applying various models to assess hydrologic ecosystem services (HESs) management has the potential encourage efficient water resources allocation. However, can a single model designed on these principles be practical carry out for all purposes? We address this question by fully discussing advantages of variable infiltration capacity (VIC) model, soil and assessment tool (SWAT), integrated valuation tradeoffs (InVEST) model. The analysis is carried both qualitatively quantitatively...

With increased attention paid to the changes of global climate, impacts on hydrological processes remain poorly understood in specific basins. In this study, we selected Luanhe River Basin, which is an important source water supply Beijing and Hebei, as a case study for analysis combined impact precipitation temperature change components semi-arid river basin. This investigated blue flow (BWF), green (GWF), storage (GWS) by employing SWAT (Soil Water Assessment Tool) model stochastic methods...

With the intensification of climate change, coupling effect between variables plays an important role in meteorological drought identification. However, little is known about contribution to development. This study constructed four scenarios using random forest model during 1981–2016 Luanhe River Basin (LRB) and quantitatively revealed (precipitation; temperature; wind speed; solar radiation; relative humidity; evaporative demand) indices characteristics, that is, Standard Precipitation...

The ecosystem service (ES) is the basis for human lives, and also one of criteria evaluating environmental conditions. Therefore, it necessary to understand how activities would affect ESs under rapid urbanization social-economic development phenomena. This study selected four vital important water-related ESs, including water yield, soil retention, purification, net primary productivity (NPP), detect structure function ecosystems had changed in Yangtze River Economic Belt (YREB) from...

Based on the meteorological and hydrological data of Yalong River Basin from 1960 to 2019, droughts were analyzed using standardized precipitation evapotranspiration index (SPEI) runoff (SRI); then, spatio-temporal evolution propagation characteristics studied multiple time scales. The results showed that, firstly, annual scale, frequencies in basin 28.3% 34.0%, respectively, past 60 years. From upstream downstream, longer alternating period dry wet periods, more significant frequency...

Climate change may substantially affect the validity of identifying eco-compensation demand. Exploring temporal-spatial variation in demands and assessing contribution climate are essential for improving justice effectiveness. Since 2000, Chinese government implemented ambitious ecological economic policies at Yangtze River Economic Belt (YREB) to balance relationship between environment protection socio-economic development. We selected YREB explore driving factors two major ecosystem...
