AMWG Meeting

March 9-10, 2004
Hotel Boulderado
Boulder, CO

Greetings to members and friends of the CCSM Atmospheric Model Working Group!

This is a preliminary agenda for the spring meeting of the AMWG, to be held in downtown Boulder, at the hotel Boulderado on March 9 and 10.

The meeting will be comprised of four (approximately half) day sessions. The final session is shorter than the others to facilitate the departure of those from the east coast making flights around 6PM. In spite of the shortened session, we urge you stay till the end. The last session is important and interesting.

We would like to begin a process of critically assessing the treatment of physical processes in CAM with an eye towards future development. An important part of this process will be to present state-of-the-science reviews of these processes to our working community as we move forward toward new approaches in CAM. For our inaugural talk we have asked Adrian Tompkins of the ECMWF to provide an overview of current approaches to parameterizing cloud fraction in GCMs, their limitations, and future prospects. Of course this topic is intimately tied to representations of other processes (e.g. convection, dynamics and cloud microphysics) and we anticipate the possibility that he will touch upon those topics in whatever detail is required as well.

March 9)

Session 1) Recent CAM developments. Before lunch Overview of model status. Interaction with other model components. Update on the coupled simulations. Review of simulations with alternate dynamical cores, different resolutions.

Session 2) Application Studies in the CAM community. After lunch studies with current model (CAM), and older configurations (CCM) variations (new dynamical cores, neural nets, data assimilation, analysis of model runs, SCAM studies, etc)

Reception: PLEASE PLAN TO ATTEND THE RECEPTION. THERE WILL BE LOTS OF FOOD, AND IT WILL BE OF A HIGHER QUALITY THAN YOU WILL USUALLY SEE AT SUCH A GATHERING!

March 10)

Session 3) The future of CAM Physics: Before lunch Review of cloud fraction parameterization (Adrian Tompkins) Discussion of what opportunities for advancements in cloud representations

Session 4) Non-cloud related opportunities for improving CAM: After Lunch aerosols? surface forcing and gravity wave drag. isotopes? chemistry? next generation dynamics? other?

We invite submissions for presentations in sessions 2 and 4.

IF YOU WOULD LIKE TO MAKE A PRESENTATION, PLEASE SEND EMAIL TO LYDIA SHIVER (lydia@ucar.edu).

If you have suggestions for revisions to the agenda, please feel free to contact the AMWG Co-chairs or AMWG liaison.
