Regional climate change is influenced greatly by regional features such as
topography , which are not well represented in global models
because of their coarse resolution. Models of higher resolution cannot
practically be used for global simulation of long periods of time.
To overcome this, regional climate models,RCM's, with a higher resolution
( 20 km) are constructed for limited areas and run for longer
periods (20 years or so).

Contributions are solicited on all aspects of regional climate changes and
regional climate models, including descriptions of cooperative
regional climate modeling projects. The session will include discussion of
potential contributions of regional climate modeling toward the IPCC
Fifth Assessment Report, including international collaborations such as
CORDEX.
