How do we model climate variability in a warmer world?: A framework for modeling ENSO-related regional climate change and variability

Current coupled general circulation model (CGCM) simulations provide an important resource for understanding physical processes that affect the large scale mean climate. However, most of these models poorly represent
many of the physical processes that are important for regional applications such as ENSO or the hydrological cycle. A new model framework is designed that bypasses many of these model deficiencies by making some physically reasonable assumptions about the climate system. The new model framework may be more appropriate for investigating regional ENSO impacts.

As an example, we apply the present model framework to project Indonesian precipitation in a global warming scenario. Some preliminary results will be presented for Indonesia and for the North Pacific.
