This research investigates the interannual variability of soil moisture as related to large-scale climate variability and also evaluates the spatial and temporal variability of modeled deep layer (40–140 cm) soil moisture in the Upper Colorado River Basin (UCRB). A three layers hydrological model VIC-3L (Variable Infiltration Capacity Model – 3 layers) was used to generate soil moisture in the ...

The recent California drought has highlighted the potential vulnerability of the state’s water management infrastructure to multiyear dry intervals. Due to the high complexity of the network, dynamic storage changes in California reservoirs on a state-wide scale have previously been difficult to model using either traditional statistical or physical approaches. Indeed, although there is a signi...

Droughts can influence forest composition directly by limiting water or indirectly by intensifying other stressors that affect establishment, growth, and mortality. Using community assemblages of eastern US tree species and drought tolerance characteristics assessed from literature, we examine recent drought conditions in relation to the spatial distribution of species and their tolerance to dr...

The article reports the issues corresponding to climate variability and possibility of droughts in spatially distinct regions Paraguay, Chaco Oriental (Paraná Basin). Based on GMT scripting approach high-resolution datasets from TerraClimate GEBCO, study examined extent annual environmental variables over Paraguay 2020: extreme temperatures, wind speed, precipitation, soil moisture, evapotransp...

Droughts are the most frequent natural disaster in regions at margins of East Asian summer monsoon (EASM), which pose threats to agriculture, economy, and human lives. However, limitations only approximately 60 years meteorological observations hamper our understanding characteristics mechanisms local hydroclimate. Trees growing marginal region EASM usually sensitive moisture variations have pl...

The reliability of paleoclimatic inferences from lake-sediment records rests on the understanding of how various sediment indicators respond to environmental changes. Despite the recent proliferation of paleoclimatic records, only a limited number of studies have rigorously evaluated potential indicators by comparing lake-sediment records with instrumental weather data. We analyzed annually lam...

Since the pioneering efforts of Duwez and co-workers in 1965, when a solid amorphous phase palladium-silicon (a-PdSi) was obtained vicinity eutectic concentration, much work has been done. However, some points related to atomic structures remain be systematized. In this work, 8 Pd100-cSic alloys (c = 2.5, 5, 10, 13.34, 15, 17.5, 20, 22 at%) are generated by molecular dynamics ab initio simulati...

Drought is one of the most destructive natural disasters causing serious damages to human society, and studies have projected more severe and widespread droughts in the coming decades associated with the warming climate. Although several drought indices have been developed for drought monitoring, most of them were based on large scale environmental conditions rather than ecosystem transitional ...
