Downloading GCM Data
« on: October 28, 2011, 12:50:10 PM »
General Circulation Model or global climate model is often shortened to GCM and can be used for weather forecasting, understanding climate and predicting climate change. General Circulation Models take many factors into account including atmospheric, chemical, biological, ocean movement and more.

There are mainly two types of GCMs are available. Atmospheric and Ocean GCMs. Separately they account for the changes within the atmosphere and the ocean respectively. Put together they make up a complete climate model which is a 'coupled' model i.e. coupled atmosphere-ocean General Circulation Models (AOGCMs).

These models most often used to make the predictions of future climate. These predictions are sometimes called scenarios. Based on different scenarios the IPCC (intergovernmental panel on climate change) can recommend measures to mitigate global warming and can predict what results a specific reduction in green house gases are likely to have.

Advanced coupled atmosphere-ocean General Circulation Model can also to some extent predict regional climate changes. These predictions help in future planning and policy making for a nation in various fields.

Appreciating your effort in presenting information in a
a precise manner which even a layman can understand.

Now even I know about GCM ;)
