### Agenda:

1. **Admin** : Volunteer for taking today’s meeting minutes to post [here](https://forum.access-hive.org.au/t/meeting-minutes-2026-atmosphere-working-group/6284/8) on the Forum.

2. **ACCESS Community updates:** (5mins)  
Placeholder for any updates from the atmosphere community.

3. **Hybrid atmospheric model development - can ACCESS-NRI play a role?** _Steve Sherwood_, UNSW (10+5mins)  
A few hybrid modelling approaches are being pursued for improving weather and climate forecasting, where “hybrid” in general just means combining machine-learning and traditional modelling approaches somehow. A particular instance is hybrid climate models that replace sub-grid physics with ML surrogates, thereby attempting to keep known physical constraints while exploiting ML to fill gaps. We will review this strategy and how (or why) ACCESS-NRI might contribute to it by generating training data for surrogates and/or developing a sovereign hybrid modelling capability.

4. **ML-Based Weather modelling at the Bureau of Meteorology** _Catherine de Burgh-Day_, BoM (20+5mins)  
Machine learning has emerged as a powerful tool for weather prediction, with major meteorological centres and research organisations around the world investing in ML-based forecasting systems - both pure ML models, and hybrid physics-ML approaches. This presentation provides an overview of the evolving international landscape, highlighting scientific potential, and key developments including hybrid spectral nudging, foundation models, Direct from Obs Prediction (DOP), ensemble prediction, regional and multi-domain models, and progress in spatio-temporal downscaling.  
The presentation will also outline the Bureau’s current activities and future plans in ML-based global and regional weather modelling, including evaluation of AIFS variants, operational prototyping of AIFS, and progress in developing a combined global-regional ML weather models for Australia.

5. **Discussion** _Andrew Brown_ (10mins)

6. **Ask the community?? 🤔** _Sonya Fiddes_ (5mins)  
Do you have a research question that you’ve exhausted ideas to find an answer to?  
Here’s your chance to ask our Atmosphere community for their ideas!

7. **Compute/storage resources:** _Heidi Nettelbeck_ (2mins)  
Any experiment proposals for Q3/2026 (2 MSU allocation)?  
→ See [here](https://forum.access-hive.org.au/t/applying-for-atmosphere-wg-resources/844) for how to apply for Atmosphere WG Resources.

8. **Next Atmosphere WG meeting:** _October 2026_
