Hi All.
One of 21stCenturyWeather’s aims is to be build a regional coupled model, combining high resolution atmospheric and ocean models.
I posted this thread on the 21stCenturyWeather Cumulus website, but I thought I’d cross-post it here to get some extra attention (it was a little love-starved over there).
"Following on from Monday’s Modelling Science. meeting, I thought I’d take a high-level look at rAM3 and CM3 and see how they work.
Here is a high-level simplified view of rAM3 from a rose/cylc view.
Note rAM3 uses a pre-built executable.
The running of CM3 is in contrast, rather opaque from a rose/cylc viewpoint. It only has four major tasks.
It’s easy to understand the Recon and Atmos tasks from a UM point of view, but I’m unsure how the coupling is done. This suggests the Atmosphere task is configured via the UM namelists and other MOM6/CICE/NUOPCY control files and the UM executable directly handles the execution of MOM6, CICE and NUOPCY coupling.
Is this correct?
Or does the compiled NUOPCY executable control the UM, MOM6, and CICE?
BTW I can’t find any reference to CABLE in the cm3-suite, but I see plenty of JULES. Does the NUOPCY version of CM3 use JULES?"
(Updated to include the correct rAM3 diagram- thanks @bethanwhite )
