در این مطالعه به منظور آشکارسازی نقش توپوگرافی بر ساختار باد سیستان، از مدل اقلیمی منطقه محدود regcm4 استفاده شد. با بهره گیری از مدل، چهار تجربه متفاوت با تفکیک افقی 20 کیلومتر اجرا شد که در هر تجربه شرایط متفاوتی از ناهمواری ها در نظر گرفته شد. در تجربه نخست، ناهمواری ها به شکل واقعی مورد استفاده قرار گرفت. در سه تجربه دیگر، مدل به ترتیب با حذف کوه های خراسان جنوبی، حذف کوه های خراسان (جنوبی،...
Impact studies have contributed to a better integrated scientific understanding of the climate and environment Amazon, in present, past, future. This work aims describe regional impacts human-induced landcover changes on RAINY (January April) DRY (July November) regime Metropolitan Region Belém (MRB), first frontier Amazonian occupation. Furthermore, dynamic downscaling (RegCM4 driven by HadGEM...
The characteristics of tropical cyclone (TC) activity over five TC basins lying within four Coordinated Regional Downscaling Experiment (CORDEX) domains are examined for present and future climate conditions using a new ensemble simulations completed as part the CORDEX-CORE initiative with regional model RegCM4. conducted at 25 km horizontal grid spacing driven by three CMIP5 general circulatio...
Under the Coordinated Regional Climate Downscaling Experiments-East Asia (CORDEX-EA-II), outputs from two regional climate models (RCMs) driven by four global (GCMs) are used to investigate characteristics and possible mechanisms of projected elevation-dependent warming (EDW) over Tibetan Plateau (TP) under Representative Concentration Pathway emission scenario 8.5 (RCP8.5). Results show that w...
Unlike global and regional assessments, the spatio-temporal variability of air temperature precipitation, caused by climate change, must be more useful when assessment is made at sub-regional to local scale. Thus, this study aims assess possible changes in precipitation patterns for late 21st century relative present Mozambique. The model, RegCM4, driven model HadGEM2, was used perform downscal...
Abstract. The influence of soil moisture initial conditions on the climate extreme indices over West Africa was investigated using fourth generation International Centre for Theoretical Physics regional model (non-hydrostatic) coupled with version 4.5 Community Land Model (RegCM4–CLM4.5) at a 25 km spatial resolution. We initialized control experiments reanalysis data from European Medium-Range...
