Modeling Techniques for Environmental Impact Assessment

Climate Models andd Regional Downscaling

Global climate models (GCM) simulate the Earth 's climate systeme by solving equations for atmosferic dynamics, radiation transfer, ocean romeation, and land surface processes. While GCM are powerful tools for projecting century- scale climate change, their coarse resolution - typically 100 to 250 0 kilometers per grid cell - is to o blunt to resolve thee effects of individual industrial facilities or urbane -scalenoma.

Regional climate models (RCM) adress this limitation by dynamically downscaling GCM outputs to resolutions of 10 t o 50 kilometers. They simulate local topography, land use patterns, and mesoscale weather fenomenasa (sea breez, mountain- valley circulations, urban heat islands).
