Study of Climate Change using GCM Downscaling: Special Reference to Indian Subcontinent

Abstract

Climate change refers to a change in a state of the climate and it is one of the emerging issues in the 21st century. General Circulation Model (GCM) represents physical processes in the atmosphere, ocean, cryosphere and land surface. It is one of the advanced tools for simulating the response of the global climate system to increasing greenhouse gas (GHG) concentrations. The application of GCMs and its downscaling outputs helps to fill up the gap existing between large-scale and local-scale variables. This study clearly showed that GCM downscaling has been increasingly applied to the study of climate change in many parts of the world including the Indian sub-continent and their results are utilized to enhance planning and management purposes.
