تا قبل از انتشار گزارش پنجم ارزیابی تغییر اقلیم (AR5) هیات بینالدول تغییر اقلیم در نوامبر سال 2013، محققان کشورمان از داده های مدل های گردش کلی سری CMIP3 برای پیشنگری تغییر اقلیم کشور استفاده می کردند؛ اما از حدود سال 2015 بتدریج دسترسی به داده های مدل های گردش کلی سری CMIP5 تسهیل گردید، به طوریکه هم اکنون اغلب پژوهش های مرتبط با پیشنگری تغییر اقلیم با بکارگیری داده های مدل های CMIP5 انجام م...
Abstract ‘Flash drought’ (FD) describes the rapid onset of drought on sub-seasonal times scales. It is particular interest for agriculture as it can deplete soil moisture crop growth in just a few weeks. To better understand processes causing FD, we evaluate importance evaporative demand and precipitation by comparing three different indices that estimate this hazard using meteorological hydrol...
While the popularity and feasibility of solar power have increased toward achieving a low-carbon climate-resilient society, it is uncertain how changes in climate attributes will affect future potential output. This study presents comparative assessment terms technology for harnessing energy from insolation (PVP vs CSP), projections (CMIP5 CMIP6), emission scenarios. Both CMIP5 CMIP6 multi-mode...
Based on the observational dataset CN05.1 and Coupled Model Intercomparison Project (CMIP), this study assesses performance of CMIP5 CMIP6 projects in projecting mean precipitation at annual seasonal timescales Yangtze River Basin China over period 2015–2020 under medium emission scenarios (RCP4.5/SSP2-4.5). Results indicate that multi-model ensemble (MME) overall has lower relative bias root-m...
Observations over the 20th century evidence no long-term warming in the subpolar North Atlantic (SPG). This region even experienced a rapid cooling around 1970, raising a debate over its potential reoccurrence. Here we assess the risk of future abrupt SPG cooling in 40 climate models from the fifth Coupled Model Intercomparison Project (CMIP5). Contrary to the long-term SPG warming trend eviden...
Almost all climate models in Coupled Model Inter-comparison Project phase five (CMIP5) were found to have a cold bias in Sea Surface Temperature (SST) over the northern Arabian Sea, which is linked to the biases in the Indian Summer Monsoon (ISM). This cold SST bias was attributed to the anomalous cold winds from the north-western part of south Asian landmass during boreal winter. However, the ...
[1] Land climate is important for human population since it affects inhabited areas. Here we evaluate the realism of simulated evapotranspiration (ET), precipitation, and temperature in the CMIP5 multimodel ensemble on continental areas. For ET, a newly compiled synthesis data set prepared within the Global Energy and Water Cycle Experiment-sponsored LandFlux-EVAL project is used. The results r...
The study evaluated the ability of 11 global climate models latest two versions Coupled Model Intercomparison Project (CMIP5 and CMIP6) to simulate observed (1965–2005) rainfall, maximum (Tmax) minimum (Tmin) temperatures, mean eastward (uas) northward (vas) wind speed, surface pressure. It also relative uncertainty in projections variables using those CMIPs. European reanalysis (ERA5) data wer...
