25 July 2023 (14:00-15:00)
18 participants online via Zoom
From: UNSW, CLEX, BoM, Monash, UniMelb, ACCESS-NRI
1. Admin
- Introduction and agenda (Yi Huang).
- Tim Raupach volunteered to take today’s meeting minutes.
2. Science presentation (Hooman Ayat)
- Authors: Hooman Ayat, Todd Lane, Michael Reeder, Yi Huang, Scott Wales, and thanks to Holger Wolff and Dale Roberts.
- Key drying mechanisms during frontal passages for 2019/2020 fire season.
- Questions/discussion: differences between observed and modelled winds (Charmaine Franklin), dry air vs. dry surface/soil moisture (Claire Vincent)
3. UM research activities (Heidi Nettelbeck)
- Collating experience within the group - please add to the research activities table on hive forum.
- Link to table: Atmospheric Modelling Research Activities using the UM
- Table includes contact emails so can be in touch if there is overlap.
- To get edit permissions you need to have spent 10 minutes looking at forum posts.
4. Combined working group meeting with forecast and prediction WG (Charmaine Franklin)
- Forecast and prediction WG is interested in the single column model
- Single-column models are useful for understanding parameterisations, good for idealised studies. Separates dynamics from physics. Assumes independence of columns so less relevant for high-res model.
- Meeting will probably be organised by Martin Dix. Martin adds:
- Single-column models also useful for debugging.
- Working in latest version of the UM.
- Could drive it with ERA5 similar to AUS2200.
- Are people interested in learning more about the single-column model at NCI? Yes, there is interest.
- Combined WG meeting will be after workshop in September.
5. ACCESS-NRI workshop update
Program (Yi Huang):
- Two day workshop, first day will include invited keynote speakers; updates for the community.
- Second day to focus more on science, including invited talks from individual working groups; breakout sessions.
- Breakout sessions to be interdisciplinary.
- For our group we need to:
- Nominate someone to give an update on Day 1.
- Think about who we want to give science talks on Day 2.
- Program link: ACCESS Community Workshop 2023 Program - ACCESS-NRI
- Workshop to be Hybrid though in-person preferred.
- Talk length ~15 minutes.
Training session at NRI workshop (Roger Edberg):
- Will be opening registrations for the training shortly.
- Multi-group effort to bring program together.
- Two longish sessions to make up the day; strong focus on ARE services from NCI.
- Note introduction to rose/cylc with CM2/AUS2200 examples.
- Working to get a space with good AV/network to ensure smooth running of the training.
AUS2200 training (Yi Huang):
- Lots of interest in being able run the high-res UM, so plan is for a half-day, more targetting training session on the Thursday.
- Follows on from rose/cycl training and gives more detail on AUS2200 configurations, regional modelling suite.
- In particular designed to show people how to run the regional nesting suite over a subset of the domain with the AUS2200 configuraiton.
- Also to cover viewing model output.
- Training for 3-4 hours in hybrid form.
- Possibility of opening registrations to aid in planning.
- Heidi notes there are polls on the forum to determine interest.
WG meeting at workshop (Charmaine Franklin):
- Charmaine proposes that we take discussion on how to use our WG meeting time to the forum.
6. Admin (Yi Huang)
- Next meeting is 2-3 pm 15 August.
- Calendar invites are available via the forum (Heidi).
