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 4 th Assessment Report.

New Model Release ► Extensive code, pre-processor, and post- processing 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 post- processing streamlining & debugging including improvements to the user- friendliness  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.  Non-hydrostatic option based in MM5 (not yet done)  Subgrid topography/land-use scheme (not yet in new version)  Emanuel convection 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)
