Transcript Slide 1

Regional Modeling Workshop
►
►
Regional teams of 5 to 10 users led by 2-3 experts.
Develop collaborative projects within the teams
that have to do with climate change over their
region.
 local people know the local climatology and related
problems of primary interest.
 do mini-assessments of what we currently know from the
models and the observed record about "climate change"
over the regions.
 some specific studies of interest for the different regions
(e.g. deforestation within the context of climate change,
aerosols, monsoons, extreme events etc.)
Goals of the Workshop
► To
re-establish a network of users
 experts
 new users particularly from developing nations
scientists.
► To
develop regional networks of users
through collaborative projects.
► A collective document (e.g. special issue of a
journal) with a possible contribution to the
IPCC 4th Assessment Report.
New Model Release
►
►
Extensive code, pre-processor, and postprocessing streamlining/debugging including
improvements to the user-friendliness
New implementations…
Tracer code (sulfates, etc.)
Zeng ocean flux scheme.
SUBEX large-scale precipitation scheme.
Non-hydrostatic option based in MM5 (not yet done)
Subgrid topography/land-use scheme (not yet in new
version)
 Emanuel convection scheme
 Parallel version (in the works…)





►
Possible future upgrades…
 Replacement of BATS with a different surface scheme
(e.g. CLM).
 Additional convection scheme (e.g. Kain-Fritsch).
New Model Release
► Extensive
code, pre-processor, and postprocessing streamlining & debugging
including improvements to the userfriendliness
 UCSC Pre- & Post-processing
 ECHAM4.5 BCs
 Diagnostic Packages
► NCL
► Source
Code Documentation, output
► Linda’s diagnostic package
► Selection of variables to output
 Selection/modification of land-use/topography
data
New Model Release
► New
implementations…
Tracer code (sulfates, etc.)
Zeng ocean flux scheme.
SUBEX large-scale precipitation scheme.

Possible additions to physics
► Stretch
grid, variable resolution
► Kain & Fritsch, Betts-Miller convective
scheme (ictp will add)
► Better documentation for physics
schemes
► Switch to CLM (Allison) with subgrid
simple scheme option
► Add cloud ice (Jeremy?), maybe
Dudhia scheme
Long-term developments
► Upgrade
numerics (maybe move
towards WRF)
New Model Release
► Possible
future upgrades…
 Replacement of BATS with a different
surface scheme (e.g. CLM).
 Additional convection scheme (e.g.
Kain-Fritsch).
