Presentation Transcript

  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.)

  2. 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.

  3. 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).

  4. 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

  5. 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

  6. 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

  7. Long-term developments • Upgrade numerics (maybe move towards WRF)

  8. New Model Release • Possible future upgrades… • Replacement of BATS with a different surface scheme (e.g. CLM). • Additional convection scheme (e.g. Kain-Fritsch).

  9. Long-term future
