This presentation will give an overview of the development and application of
the Rossby Centre Coupled Regional Climate Model, developed at the Swedish
Meteorological Service. Results will be presented illustrating the
performance of the model over Europe, the Arctic and tropical Pacific for
both present and future climates. The climate simulated by a regional climate
model is first order sensitive to the quality of the applied boundary
conditions. With this in mind, I will discuss the use of regional models as
well constrained test beds for developing and evaluating parameterisation
schemes for potential application in both global and regional
models. Examples will be given of how a combination of regional models,
single coulmn models and explicit (cloud resolving) models can be combined to
aid in improving parameterisation schemes. Particular attention will be paid
to the respresentation of moist processes and related subgrid scale
transports (turbulence and convection) and their interaction with both solar
and terrestrial radiation. Suggestions will be given for the most productive
use of regional models in attempting to best provide reliable simulations of
climate and future climate change .
