CMMAP: Interactions of Deep and Shallow Convection and TurbulenceFrom Steve KruegerDate January 12, 2008 Hello, If you have already rec'd this once or twice, I apologize! But I suspect that many did not get it the first two times I sent because of spam filters. The short version of this email is: The theme group on Interactions of Deep and Shallow Convection and Turbulence will be meeting on Wednesday, Jan. 16 in the morning during the first breakout session. We are asking for short reports (1 minute to 10 minutes or so) on progress and plans related to this theme. Please let us know by Monday evening. Thanks!

We would like to present and discuss our progress and plans on the action items from our last meeting, which are summarized here. (The complete report from the Aug 2007 CMMAP meeting is included further below.) Already planned presentations are listed. We need more. Please tell us about the topics you'd like to present/discuss by Thursday, Jan 10. Note that there is no poster session at this meeting. Steve and Chin-Hoh ACTION ITEMS FOR JAN 2008 (short-term plans) - Analyze existing and new benchmark simulations. ACTION ITEM: Perform large-domain LES of deep convection. Moeng: very large LES of a CBL--- (2048)^3 grid points Krueger: progress with SAM - Analyze observational datasets. ACTION ITEM: Identify and/or develop appropriate datasets. Krueger: ISCPP simulator results for SP-CAM http://www.cmmap.org/cmmap/research/themes/data/spcam30_4km_32c-obs/set13/set13.htm (This is a result of efforts by the KT group.) - Identify physical processes responsible for MMF deficiencies (e.g., great red spot)A ACTION ITEM: Analyze existing MMF simulationsA Krueger: ISCPP simulator results for SP-AAM (see above) ACTION ITEM: Perform new MMF simulations that involve changes to MMF physics. - Test improved physics in SAM. (This should have been included but was not.) ACTION ITEM: Implement and test improved physics in SAM LONG-TERM PLANS - Test improved physics in MMF. ---------------------------------------------------------------------------------------------------------- Steven K.

Better understand interactions of deep and shallow clouds, and turbulence. 2. Better understand representation of interactions of deep and shallow clouds, and turbulence in prototype MMF. 3. Test improved physics in MMF. ACTION ITEMS FOR JAN 2008 (short-term plans) 1. Better understand interactions of deep and shallow clouds, and turbulence. - Analyze existing and new benchmark simulations. ACTION ITEM: Perform large-domain LES of deep convection. (Computer time is required.) - Analyze observational datasets. ACTION ITEM: Identify and/or develop appropriate datasets. 2. Better understand representation of interactions of deep and shallow clouds, and turbulence in prototype MMF - Identify physical processes responsible for MMF deficiencies (e.g., great red spot). ACTION ITEM: Analyze existing MMF simulations. ACTION ITEM: Perform new MMF simulations that involve changes to MMF physics. (Computer time is required.) (1) Use CAM physics except for convection tendencies (Q1, Q2). (2) Replace boundary layer turbulence scheme used in CRM. LONG-TERM PLANS 3. Test improved physics in MMF. ISSUES - Computer time will be required for the proposed simulations. - Large size of large-domain LES output dataset will make it a challenge to access and analyze. We need help to design. - Access to SP-CAM code and results: We need a clone of Marat! From Steve Krueger Date January 9, 2008 I have not received any responses so I am not sure that the mailing list is operating properly. Please respond to let me know if you will be at the CMMAP meeting and plan to attend the break out session. Suggestions for topics to discuss other than what is listed below are welcome. If you don't want to make a presentation yourself, please send me a short progress report that I can present as part of our report to plenary. It will help us to have that information before the break out session (by Tuesday). If you do want to make a presentation, please send me a copy of it, or a short report, whichever you prefer. One possible topic of discussion will be how to best coordinate our efforts. Thanks, Steve and Chin-Hoh |
