Human-caused long-term changes in global aridity

open access: yesnpj Climate and Atmospheric Science, 2021
Widespread aridification of the land surface causes substantial environmental challenges and is generally well documented. However, the mechanisms underlying increased aridity remain relatively underexplored.

Estimating spatial distribution of aridity and moisture indices of Mongolia using remotely sensed time series data

open access: yesProceedings of the Mongolian Academy of Sciences, 2021
The aim of this study is to estimate the spatial distribution of aridity and moisture indices using remotely sensed time-series data. For the analysis, we have chosen two simple climatic indices.

Belowground soil and vegetation components change across the aridity threshold in grasslands

open access: yesEnvironmental Research Letters, 2023
Grassland ecosystem functions are affected by global climate change and increasing aridity. Belowground components of soil and vegetation, such as specific root length, belowground biomass and soil organic carbon are important for maintaining these ...

Simulated changes in aridity from the last glacial maximum to 4xCO2

open access: yesEnvironmental Research Letters, 2017
Aridity is generally defined as the ‘degree to which a climate lacks moisture to sustain life in terrestrial ecosystems’. Several recent studies using the ‘aridity index’ (the ratio of potential evaporation to precipitation), have concluded that aridity ...

Attribute Analysis of Aridity Variability in North Xinjiang, China

open access: yesAdvances in Meteorology, 2016
Identifying the dominant meteorological factors affecting aridity variability can improve our understanding of climate change and its future trend in arid and semiarid regions.

Normalized Seed Weight of Three Species of the Genus Peganum L. (Peganaceae Van Tieghem) in Mongolia [PDF]

open access: yesMongolian Journal of Biological Sciences, 2015
Variation of seed weight of Peganum species is positively correlated with mean seed weight in big populations. It was insignifi cant in small populations, suggesting normalized seed weight is useful to distinguish the population

Spatial-Temporal Variation of Aridity Index of China during 1960–2013

open access: yesAdvances in Meteorology, 2016
Aridity index, as the ration of potential evapotranspiration and precipitation, is an important indicator of regional climate. GIS technology, Morlet wavelet, Mann-Kendall test, and principal component analysis are utilized to investigate the spatial ...

Assessing the aridity indices in Northeast Iran: Implications for climate change and agricultural water management. [PDF]

open access: yesDesert
Aridity indices have been widely applied in dividing climate regimes and monitoring drought events. The knowledge of the aridity index and reference evapotranspiration is very important not only for understanding climate change and its effects on ...

Amendment of Climate Zones of the Northeastern Iran Based On a Combination of Changes in Aridity Index [PDF]

open access: yesمدیریت بیابان, 2019
The purpose of research is to rezoning the climate zones of the north east of Iran- located between 30° 35' to 38° 41'N and 56° 19' to 61° 16'E- based on the analysis of changes in the aridity index, in combination with other climatic parameters changes.
