New review led by @ariaan.bsky.social on climate effects of the Southern Annular Mode, the most important mode of climate variability in the Southern Hemisphere. Read it in @natrevearthenviron.nature.com at doi.org/10.1038/s430... 🧪 #academicsky #climate #climatechange
Southern Annular Mode dynamics, projections and impacts in a changing climate - Nature Reviews Earth & Environment
The Southern Annular Mode (SAM) has shifted towards its positive phase owing to ozone depletion and increasing greenhouse gas concentrations. This Review discusses the dynamics, trends and projections...

In the latest edition of the Bulletin of the Australian Meteorological and Oceanographic Society, I am taking another look at this year's Sudden Stratospheric Warming. I think it had more of an impact than I thought it would back in September. viewer.joomag.com/bamos-vol-38...

Busy days around what might become to be known as the 2025 Sudden Stratospheric Warming: Loads of media interest, and thanks to the journalists who take their time to talk to me before writing their story. Happy to take some of mine in turn. theconversation.com/air-temperat...

Thanks to ABC TV News Channel for the chat about the stratosphere, sudden warmings, and the weather to come!

wait, is there another typhoon following #Ragasa (1) and #Neoguri (2)?
September 23, 2025 at 11:37 PM
Super Typhoon #Ragasa definitely has an eye. Here seen from relatively low-resolution GFS data. But there’s also some wild dynamics happening all over the Pacific. #weather #sciviz
September 23, 2025 at 4:17 AM
Busy Western Pacific right now. Cat 5 (Ragasa) and 4 (Neoguri) not far from each other. I wonder whether the strong tropical Pacific activity could be linked to the unusually weak Antarctic stratospheric polar vortex at the same time? 🤔 #sciviz #Ragasa #Neoguri

I propose calling the current low pressure system the Heart Low. This is what the forecast looks like for later today. 🤍 #sciart #weather

This was an interesting piece of work with George Driver from the AAP: debunking stuff which sounds very sophisticated, gets many things right, and is still completely wrong. Hopefully an insightful read 🧪 aapnews.aap.com.au/news/former-...
Former senator's global warming claims misrepresent physics: experts
Outgoing Queensland senator Gerard Rennick claims global warming could not occur because it goes against the laws of physics, but experts say his claims misunderstand how CO2 warms the earth.

So proud of my (now former) student Valentina Ortiz Guzman who just submitted her thesis 🥳🎉 This is not just her first PhD submission, but also my first submission as primary supervisor. So loads of firsts for everyone!

Here’s a good writeup about this (with a focus in Australia) from Kamilia Palu: au.news.yahoo.com/major-disast...
Major disaster from three years ago could impact Australia's winters for years
The eruption happened more than 1200 days ago, but we could start to see the strongest impact from this year.

A new study by @drjucker.bsky.social and colleagues reveals climate models show strong dry biases on eastern continental coasts due to convective representation and dynamics. Caution is advised when using climate models to assess rainfall trends in these regions.

5. We suggested there might be a relation between the volcano and the evolution of ENSO. I think this one is still out there and I'm excited to see new, more comprehensive model simulations slowly coming out and pointing to similar ideas. 5/5
