¥Climate modeling is hard.
¥We can never obtain exact solutions to the governing equations.
¥The spatial resolution (grid point spacing) possible with present-generation
computers leaves out many things we are interested in, or requires that we
represent them using educated guesswork (i.e., parameterization).
¥There
are advantages to doing lots of runs using lots of models (i.e.,
ensemble simulations).
¥Regional climate models give a way to use improved resolution over a
particular area of interest.
