Dear Deep and Shallow Convection Group:<p></p>

We will be meeting on Wednesday, Jan. 16 in the morning during the first<br />
 breakout session regarding Deep and Shallow Convection.<p></p>

We would like to present and discuss our progress and plans on the action<br />
items from our last meeting, which are summarized here. (The complete report<br />
from the Aug 2007 CMMAP meeting is included further below.) Already planned<br />
presentations are listed. We need more. Please tell us about the topics<br />
you'd like to present/discuss by Thursday, Jan 10. Note that there is no<br />
poster session at this meeting.<p></p>

Steve and Chin-Hoh<p></p>

ACTION ITEMS FOR JAN 2008 (short-term plans)<p></p>

- Analyze existing and new benchmark simulations.<br />
	ACTION ITEM: Perform large-domain LES of deep convection.<br />
		Moeng:  very large LES of a CBL--- (2048)^3 grid points<br />
		Krueger: progress with SAM<p></p>

- Analyze observational datasets.<br />
	ACTION ITEM: Identify and/or develop appropriate datasets.<br />
		Krueger: ISCPP simulator results for SP-CAM<br />

(This is a result of efforts by the KT group.)<p></p>

- Identify physical processes responsible for MMF deficiencies (e.g., great red spot)A<br />
	ACTION ITEM: Analyze existing MMF simulationsA<br />
		Krueger:  ISCPP simulator results for SP-AAM (see above)<br />
	ACTION ITEM: Perform new MMF simulations that involve changes to MMF physics.<p></p>

- Test improved physics in SAM. (This should have been included but was not.)<br />
	ACTION ITEM: Implement and test improved physics in SAM<p></p>

LONG-TERM PLANS<p></p>

- Test improved physics in MMF.<p></p>

STRATEGY<p></p>

1. Better understand interactions of deep and shallow clouds, and turbulence.<p></p>

2. Better understand representation of  interactions of deep and shallow clouds, and turbulence in prototype MMF.<p></p>

3. Test improved physics in MMF.<p></p>

ACTION ITEMS FOR JAN 2008 (short-term plans)<p></p>

1. Better understand interactions of deep and shallow clouds, and turbulence.<p></p>

- Analyze existing and new benchmark simulations.<p></p>

	ACTION ITEM: Perform large-domain LES of deep convection.<br />
(Computer time is required.)<p></p>

- Analyze observational datasets.<br />
	ACTION ITEM: Identify and/or develop appropriate datasets.<p></p>

2. Better understand representation of  interactions of deep and shallow clouds, and turbulence in prototype MMF<p></p>

- Identify physical processes responsible for MMF deficiencies (e.g., great red spot).<br />
	ACTION ITEM: Analyze existing MMF simulations.<br />
	ACTION ITEM: Perform new MMF simulations that involve changes to MMF physics.  (Computer time is required.)<br />
	(1) Use CAM physics except for convection tendencies (Q1, Q2).<br />
	(2) Replace boundary layer turbulence scheme used in CRM.<p></p>

LONG-TERM PLANS<p></p>

3. Test improved physics in MMF.<p></p>

ISSUES<p></p>

- Computer time will be required for the proposed simulations.<p></p>

- Large size of large-domain LES output dataset will make it a challenge to access and analyze. We need help to design.<p></p>

- Access to SP-CAM code and results: We need a clone of Marat!<p></p>

I have not received any responses so I am not sure that the mailing list is operating properly.<p></p>

Please respond to let me know if you will be at the CMMAP meeting and plan<br />
to attend the break out session. 
Suggestions for topics to discuss other than what is listed below are welcome. <p></p>

If you don't want to make a presentation yourself, please send me a short<br />
progress report that I can present as part of our report to plenary. It will<br />
help us to have that information before the break out session (by Tuesday).<br />
If you do want to make a presentation, please send me a copy of it, or a<br />
short report, whichever you prefer. <p></p>

One possible topic of discussion will be how to best coordinate our efforts. <p></p>

Thanks,<p></p>

Steve and Chin-Hoh
