It has been widely accepted that human influenced emission of green house gases are largely responsible for the climate change which we are experiencing currently. To produce detail information as a guide line for long term future climate change evolution arising from global warming, a projection approach is generally adopted to study the changes in regional climate. Regional climate modeling, as a part of down scaling techniques, to enhance the regional details due to geographical forcing is a very useful technique for over coming insufficient aspects of the GCMs such as narrow mountain...
