I got to explain the stratosphere in the Totally Cooked podcast together with @juliearblaster.bsky.social and the @21stcenturyweather.bsky.social. So much fun to discuss real (and not so real) science! 🧪 21centuryweather.org.au/engage/total...
got to bring out my competitive side, running for my local surf live saving club at the New South Wales State Championships. This after repeated injuries, so doubly stoked to bring home two medals. go Coogee!
another flooding. this time N American West Coast.
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
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)?
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

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
finally we’ve done it. grand final winners 2025 ⚽️🏆now I’m ready for summer sports.
anyone in need of a reminder how stupid AI is?
yes. it’s loving us very much!

I propose calling the current low pressure system the Heart Low. This is what the forecast looks like for later today. 🤍 #sciart #weather
Clearer skies a prime driver of heating

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-...
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...
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
4. On the other hand, the larger ozone hole observed in spring 2023 did evolve as predicted, and the resulting positive Southern Annular Mode might well have been the reason the 2023-24 southern hemisphere summer was not as expected from the co-occurring El Nino. One prediction come true? 4/5
3. We might never know the actual, isolated climate impact because it gets drowned in all these other effects. Maybe this means it had no effect, but that would be wrong in the sense that a similar eruption in a more stable period (past or future) might still have measurable impact. 3/5
2. I would expect current sea surface temperature anomalies to dominate over any regional influence the volcano might have had. So I don't think the "weird" weather we are seeing in many places around the globe should be attributed to Hunga Tonga. 2/5
