Abstract Storms include a range of weather events resulting in heavy liquid and solid precipitation high winds. These critically impact crops natural resources and, turn, health, economy, infrastructure safety. The intensity frequency the physical mechanisms triggering storms will most likely increase under global warming due to changing flows water energy atmosphere. Addressing storm threats holistically requires nexus approach that links climate change, infrastructure, human prosperity...
Abstract Cycles of freeze–thaw (FT) are among the key landscape processes in cold regions. Under current global warming, understanding alterations FT characteristics is a great importance for advising land management strategies northern latitudes. Using generic statistical approach, we address impacts compound changes air temperature and snow depth on responses across Québec, Canadian province ~ 2.5 times larger than France. Our findings show significant complex to depth. We note vivid...
Abstract Extreme rainfall events are expected to intensify with global warming, posing significant challenges both human and natural environments. Despite the importance of such assessments, they unevenly widespread across globe. Here, using bias corrected climate simulations latest phase Coupled Model Intercomparison Project (CMIP6), we provide a comprehensive assessment on how different change Brazil. Specifically, (a) explored projected changes in intensity frequency belonging right‐tail...
Hydrological droughts are often viewed through the immediate lens of atmospheric droughts, driven by precipitation deficits and evaporative demand. However, these can be exacerbated long-term impacts baseflow changes, which alter groundwater-fed streamflow critical for sustaining hydrological systems during prolonged dry periods. This study employs a global dataset 7,138 catchments PCMCI+ causal discovery algorithm to unravel spatiotemporal drivers changes their relationship with drought...
Agriculture is a cornerstone of global food production, accounting for substantial portion water withdrawals worldwide. As the world’s population grows, so does demand in agriculture, leading to alterations regional water–energy balances. We present an approach identify influence agriculture on balance using empirical data. explore departure from Budyko curve catchments with agricultural expansion and their associations changes causal discovery algorithm. Analyzing data 1,342 across three...
China’s rapid population growth has inevitably led to a need for cropland expansion meet food security challenges. In arid regions such an is restricted by limited water resources, and increase in productivity per area must be achieved while still limiting use. However, the response of agroecosystem Water Use Efficiency (WUEa.e.) alterations use Northwest Hexi Corridor not been documented any great detail. This our understanding region’s water-carbon interactions and, particular, how...
The Budyko water balance is a fundamental concept in hydrology that links aridity to how precipitation divided between evapotranspiration and streamflow. While the model powerful, its ability explain temporal changes influence of human activities climate change limited. Here we introduce causal discovery algorithm explore deviations from balance, attributing them interventions such as agricultural snow dynamics. Our analysis 1342 catchments across U.S. Great Britain reveals distinct...
Abstract Baseflow, the sustained flow from groundwater, lakes, and snowmelt, is essential for maintaining surface water flow, particularly during droughts. Amid rising global demands climate change impacts, understanding baseflow dynamics crucial resource management. This study offers new insights by assessing controls at finer temporal scales examining their relationship with hydrological drought flows. We investigate how climatic factors influence seasonal in 7138 catchments across five...
Abstract. Climate change affects natural streamflow regimes globally. To assess alterations in regimes, typically temporal variations one or a few characteristics are taken into account. This approach, however, cannot see simultaneous changes multiple characteristics, does not utilize all the available information contained hydrograph, and describe how to what extent evolve from another. address these gaps, we conceptualize as intersecting spectrums that formed by characteristics....
Abstract Droughts exert widespread impacts on both natural and social systems, there is accumulating evidence that this situation may worsen in the context of global warming. Despite importance assessing changes droughts to understand their potential future society, studies are unevenly distributed worldwide. In study, utilizing bias-corrected CMIP6 simulations a standard precipitation-evaporation index based approach, we quantified expected drought properties across 735 Brazilian catchments...
Quantifying the dynamics of snow depth is essential for understanding freshwater availability, mitigating flood and drought hazards, monitoring effects climate change in cold regions. Here, a statistical approach describing monthly loss (SDL) developed tested 67 stations throughout southern Canada. The framework fuses an input selection scheme with multiple linear regression to approximate SDL using set proxies, either explicitly or implicitly through modeling depth. Our findings suggest...
Snowmelt is a vital source of freshwater for large proportion North America’s population. Sudden snowmelt can also lead to various extreme events and environmental hazards, such as floods in the cold season droughts upcoming warmer months. However, this natural water resource at risk due climate change variability. Temperature precipitation are significant climatic controllers that regulate dynamics. Warmer temperatures affect extremes, persistence, distribution, while changing...
The water crisis is one of the important issues in Middle East countries. Many lakes are drying up and/or facing critical situations, exerting tremendous impacts on socio-economics of their region. Lake Urmia, northwestern Iran, currently situations and the brink total shrinkage environmental disaster. This paper investigates roots crises through trend analysis hydrologic variables shows impact lake desiccation altering local climate. results indicate an increase temperature, a...
Abstract. Climate change significantly affects natural streamflow regime. To assess alterations in regime, typically few characteristics are considered and their significant variations time space taken as a notion of change. Although, this approach is informative, intuitively appealing widely-implemented, (1) it cannot see simultaneous changes multiple characteristics; (2) does not utilize all the available information contained hydrograph; (3) describe how to what extent one regime evolves...
We present an integrated data portal and retrieval system for various variable related to hydrology cryosphere of Québec, named Cold Region Data Accessibility Portal Québec (CRDAP-QC). The raw with which this platform is built are pulled from publicly available sources. integrates variables climate (maximum, minimum mean temperature along total precipitation), snow accumulation (snow cover depth) as well Freeze-Thaw characteristics. enables downloading, visualizing, comparing these across...
Seasonal Freeze-Thaw cycles (FT) is a key to environmental processes and socioeconomic activities across northern latitudes. The large-scale dynamics of FT are mainly governed by air temperature snow depth. We argue that this physical control can be empirically characterized, represented, simulated the trivariate dependence structure between FT, temperature, To showcase this, we consider gridded data these variables over Québec, Canada, use canonical vine copulas formulate interdependence...
