There are a few people developing their own regional MOM6 configurations and we (@mmr0 and I) thought it would be nice for us all to keep in regular contact for mutual support and advice (see below for details). If you are interested in joining us, can you please reply to this post (or message me) and fill out the poll to indicate availability.
Regional MOM(6)’s support group.
Why: Is your small model cranky? Throwing tantrums? Waking (crashing) often? Need constant minding? Are your friends sick of hearing about your model’s inputs and outputs?
What: A support group for asking questions, sharing information, and supporting one another!
When: Once a month for an hour at a day and time yet to be chosen. Vote here for your availability. Poll closes Wed 1st October
Format: Casual. There will be space to bring your own questions, issues and updates
Who: Anyone who is running regional MOM6 configurations. Anyone who is about to start running regional MOM6 configurations. Anyone who wishes they were running a regional MOM6 configuration but can’t because of cryptic error message.
Anyone interested in regional MOM6 is welcome to attend.
Meetings will then be the once every 4 weeks with a break over Dec/Jan.
For the first meeting, please come prepared to give a short (1-3 mins, slides optional) introduction on what you are working on, or are planning to work on. Don’t feel you need to spend too long preparing for this –off the cuff will work.
The current agenda is:
The support group aims (Madi and Helen)
Introduction to everyone’s project (everyone)
Regional MOM6 support structure and future plans (Madi and Helen)
ACCESS-NRI update (Helen)
Any issues/successes to share?
You are welcome to add agenda items – or to bring along a regional MOM6 related issue, question or success. Post here or email me if you want to add something
Structure to seek support, discuss experimental design, bugs etc
Awareness of experiments in progress & completed to enable collaboration
Roundtable - who are we / what are we working on (All)
@mmr0 - Southern Ocean / Tasman sea domains with a focus on resolution (10, 3, and 1km) & how it impacts the representation of surface ocean processes & air-sea fluxes.
@claireyung - Pan-Antarctic regional with ice shelves. Current focus on validation & tuning.
@Lizzie - Australian North West Shelf (NWS) domain encompassing parts of Indonesia, and including WOMBAT to look at the effect of tides on biogeochemistry
@janjaap.meijer - [planned] Meander region south of Aus/NZ. Regional model needed to resolve submesoscales & output high-frequency diagnostics not available in existing products
@cbull - Current ACCESS-NRI Ocean team lead, but also long-time regional modeller enthusiast using NEMO
@dougiesquire - ACCESS-NRI Ocean team, has been helping develop pan-An and NWS domains
Discussion points
Although we didn’t have too much time, several discussion points emerged from the roundtable.
Budgets and conservation - Claire is interested in heat/freshwater/volume budgets, mainly as a bug-finding tool. How to calculate for regional models? What extra diagnostics might be needed at the boundary (or for a sub-region?)?
Spin-up/equilibration times - Some discussion around what this means for regional models, which diagnostics to look at (e.g., KE and EKE), how this is affected by the change in resolution from forcing dataset → regional model, and how this is affected by flow conditions (e.g., coherent jet → chaotic eddy field) [madi - suggest this could be a good topic for a future meeting?]
