13. Dynamic Downscaling
RegCM3 is a compressible, finite difference model with hydrostatic balance and vertical sigma-coordinates.
Similar a MM5 pero adaptado para estudios climáticos.

26. Importance
of
HPC
• Increased
compu<ng
power
for
atmospheric

weather
and
climate
provided
informa<on
for
decision

scien<sts
and
general
public.
• Forecast

predic<on
need
strong
scaling:
faster
nodes
and
processors,
not
more
of
them.
• The
new
genera<ons
of
mul<-‐
and
many-‐core
processors
are
an
op<on.
• Developments
in
so`ware
area
are
required
to
use
new
technologies.
