After a week of talks, networking opportunities during the pre-conference meet-up, ECR event, AMOS dinner, and experiencing the Great Barrier Reef as well as Madja (forest) at the JCU Diantree rainforest observatory, we hope all got home safe. See you all in February 2026 in Hobart

This weekend, some of our AMOS members went to the James Cook University Daintree Rainforest observatory. This place has the facilities for any research related to the rainforest productivity as well as their animals.

Today, some of our AMOS members got the chance to visit the Great Barrier Reef sponsored by Reef Unlimited and GBR Biology

#AMOS2025 ended today. Enriching discussions took place in Cairns about diverse topics of Australias weather, climate, and ocean dynamics. Tomorrow some of our members will experience the Great Barrier Reef wonders while others reflect on all we learned in the past 4 days

Cape Grim atmospheric composition observation station has been taking measurements (aerosols, radon, CO2, O3, CH3CCl3) for the past 49 years. Contributing to international assessments of atmospheric composition

UN reported 1.1 million deaths due to lead in petrol in 2011

Atmospheric composition can affect human health (through air pollution).

Aerosols are masking the warming effect that greenhouse gases make in the atmosphere

Our last plenary of the day, and the conference, is given by A. Prof. Robyn Schofield about atmospheric composition

Challenge: How to do event attribution analysis if there is a large spread of precipitation analysis between products?

Challenge: Reanalyses and satellite precipitation estimates have a large variability of their global estimates (both land and ocean). In-situ data (especially with more than 50 years of records) are limited to land areas, mostly in the USA and Australia

What we know: 1. Global means precipitation increases with global warming. 2. Extreme precipitation follows Clausius-Clapeyron. 3. Southern Hemisphere storm track has shifted polewards. 4. Global models are getting better

Next, Prof Lisa Alexander talks about what we know (and don't know) about large-scale precipitation.

Higher resolution models can also better represent wave breaking, an important process to forecast heatwaves and flooding events

Convective processes important to represent mesoscale convective systems are aerosols, shallow clouds, and boundary layer processes. Depending on the region, one of them would be the primary driver of convection

Representing orgraphic flows can help into better representing precipitation and snow accumulation

Topography is better resolved in higher resolution models and, therefore, land processes as well as convection.

Andreas Prein from ETH talking on the large-scale effect of small processes

Just finished the Regional Climate session at AMOS. It's great to see all the work going on in this space. Thanks to Marcus Thatcher, my co-organiser, shown giving his talk below.

Thanks for sharing

Each country has a different metric to better predict heat mortality

Affection can be during different time scales

Heat can impact humans by drowning, cardiovascular diseases, skin cancer, among others
