Global M-I Coupling "Pre-Challenge" 
Mini-GEM Fall AGU 2005, Sunday Dec 4th 3:30
---------------------------------------------------------------------------
From: David Murr <david.murr at dartmouth.edu>

Our goal for this session is to discuss and construct the best possible 
"GEM Challenge" for the Global MI Coupling working group. By "best 
possible" we mean a "challenge" that will produce the greatest possible 
return in terms of new insights into the physics governing MI coupling on 
global spatial scales. To this end we have identified five intervals for 
study as a "Pre-Challenge"; it is hoped that global modelers and 
observationalists will present and discuss their results and measurements 
for these five intervals at this session. By examining these five 
intervals we will determine the qualities and requirements of a "challenge"
event(s) that would best expose the underlying physics of global MI 
coupling and how well these dynamics are currently represented in the 
global models. (We hope to expose any existing observational weaknesses as 
well.) Please visit http://engineering.dartmouth.edu/~dmurr/minigem/
