تأثیر تغییر اقلیم بر درجه حرارت حوضه آبریز زایندهرود با استفاده از محاسبات نرم یادگیری ماشینی بیزین
This study aims to investigate the changes of minimum and maximum temperature variables under the impact of climate change for time period of 2015-2100 in the Zayandeh-Rud River Basin. The outputs of 14 Global Climate Models (GCMs) under three green-house emission scenarios (RCP2.6, RCP4.5, and RCP8.5) are employed from the Fifth Assessment Report (CMIP5) of Intergovernmental Panel on Climate C...
Land-use and land-cover changes (LULCC) significantly affect weather and climate as iswell documented in the scientific literature. These impacts include changes in air temperature, precipitation, atmospheric moisture content, energy fluxes, and mesoscale and potentially large-scale circulations. Recently, the United States National Research Council (2005) highlighted the importance of LULCC an...
The complex political and social context where local and regional policies are being developed plays a decisive role in the development of climate change adaptation. This article examines the phenomenon of climate change adaptation in Dutch communities by focussing on the policy process of local adaptation to determine the main factors that drive policy actors in these municipalities to impleme...
Spatial and temporal patterns of Holocene vegetation and climate changes in arid and semi-arid China
Pollen data from 30 sites in arid and semi-arid regions of China were reviewed to document regional patterns of Holocene vegetation and climate change and to understand the large-scale controls on these changes. Vegetation at most sites in eastern Inner Mongolia switched between forest, forest steppe, and typical steppe, showing maximum moisture conditions before 6 ka (1 ka 1⁄4 1000 cal yr BP) ...
The impact that changes in future climate, anthropogenic US emissions, background tropospheric composition, and land-use have on summertime regional US ozone and PM2.5 concentrations is examined through a matrix of downscaled regional air quality simulations, where each set of simulations was conducted for five months of July climatology, using the Community Multi-scale Air Quality (CMAQ) model...
