due to climate changes, precipitation forecast average in time scale is one of the most important challenges for specialists in the recent years. the purpose of this research is to investigate the capabilities of the dynamic model regcm4 in precipitation forecast in cold period of fars province. in this study, september to february or 6 month is considered as the cold period. several variable s...
This study presents the interannual variation in summer monsoon rainfall during El Nino Southern Oscillation (ENSO) phases, that is, and La Nina throughout Indian subcontinent its subregions 1986–2010. The analysis includes performance assessments of regional climate model (RegCM4) simulating through comparison with India Meteorological Department data. Observation clearly demonstrates Nino/La ...
In this study, precipitation simulated annual and seasonal in East and North-East of Iran ,in 1987-2011, by using RegCM4 dynamic model in two case; with and without using post-processing technique. The required data for RegCM4 model with NetCDf format, received from ICTP center. For the implementation of the main dynamic model, Convective precipitation test scheme and the horizontal resolution,...
This study investigates the sensitivity of simulated tropical cyclones (TC) affecting Philippines to convective parameterization schemes (CPS) in Regional Climate Model Version 4 (RegCM4). Five ERA-Interim driven RegCM4 simulations at 25-km horizontal resolution were conducted utilizing CPS Grell with Arakawa–Schubert closure (GR), Emanuel (EM), Kain–Fritsch (KF), Tiedtke (TE), and a combined s...
هدف این پژوهش بررسی کارایی مدل اقلیمی regcm4 در شبیه سازی بارش دورۀ سرد (سپتامبر تا فوریه) سال های 1990 تا2010 در جنوب غرب ایران (استان فارس) از طریق ریزمقیاس نمایی دینامیکی داده های دوباره تحلیل شدۀ مراکز ملی پیش بینی محیطی مرکز ملی پژوهش جوی (ncep/ncar) با تفکیک افقی 5/2 × 5/2 درجه است. داده های شرایط مرزی از مرکز بین المللی فیزیک نظری و بارش دیدبانی ماهانه از ادارۀ کل هواشناسی استان فارس اخذ...
انرژی مصرفی نه تنها خود تولیدکننده گازهای گلخانهای است؛ بلکه میزان مصرف آن جهت گرمایش و سرمایش محیط نیز تحت تأثیر تغییرات اقلیم و گرمایش جهانی ناشی از گازهای گلخانهای است. هدف از این پژوهش پیش بینی نیاز سرمایش استان فارس در دهههای آینده است. این پژوهش با استفاده از دادههای گردش کلی جوّ eh5om واکاوی شد. دادهها تحت سناریو a1bکمیته بینالمللی تغییر اقلیم و با تفکیک 75/1 درجه طولی و عرضی اجرا...
For the optimal performance of climate simulation, it is critical to localize physical parameterization schemes models, especially in regions with unique geographic characteristics. To study different for simulation upper reaches Yangtze River Basin (UYRB), we conducted short-term simulations a resolution 50 km from 1990 1993 using RegCM4 driven by ERA-Interim. Simulations 72 scheme combination...
Este estudo tem como objetivo classificar os tipos de ciclones sobre o oceano Atlântico Sul em três projeções do Regional Climate Model (RegCM4), bem nos modelos globais (MCGs) que forneceram as condições fronteira para regional, e identificar sistemas fazem transição tropical (TT). O cenário climático utilizado é RCP8.5. A classificação dos envolve a utilização algoritmos: primeiro rastrear no...
There are no studies related to the influence of coupling between South Atlantic Convergence Zone (SACZ) and El Niño-Southern Oscillation (ENSO) pattern variability on future changes in austral summer (December-February, DJF) precipitation over central Andes. Therefore, we evaluated historical simulations (1980–2005) projections (2070–2099) for Representative Concentration Pathway 8.5 (RCP 8.5)...
