Four sets of downscaling simulations based on the Eta Regional Climate Model forced by two global climate models, HadGEM2-ES and MIROC5, RCP scenarios—8.5 4.5, have been carried out. The objective this work is to assess change over South America simulations. future changes are shown in timeslices 30 years: 2011-2040; 2041-2070 2071-2100. response nested larger than MIROC5. Major warming area located central part Brazil. In austral summer, reduction precipitation increase southeastern...
To provide long-term simulations of climate change at higher resolution, Regional Climate Models (RCMs) are nested in global models (GCMs). The objective this work is to evaluate the Eta RCM driven by three models, HadGEM2-ES, BESM, and MIROC5, for present period, 1961-1990. domain covers South America, Central Caribbean. These will be used assessment projections region. Maximum temperatures generally underestimated domain, particular MIROC5 simulations, summer winter seasons. Larger spread...
This study evaluates the use of tiles to estimate effects surface heterogeneities in simulations local climate a landscape‐fragmented region Amazonia. Three experiments using Eta/Noah‐ MP model were designed as follows: two with spatial resolution 5 km and without tile approach. The third experiment used finer 2 approach (high‐resolution experiment). Simulations carried out for rainy dry seasons, which correspond months March September 2003, respectively. In general, magnitude fluxes is...
Accurate and detailed datasets are crucial for assessing climate change impacts. Regional models provide high-resolution simulations key tools but often exhibit systematic biases. Therefore, this paper presents a dataset derived from bias-corrected Eta regional model projections driven by four global CMIP5 models. The correction applied to daily precipitation, potential evapotranspiration, actual 2-m air temperature, was conducted on 0.2° x grid over South America. covers two periods:...
