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.
