🔭 It's paper day! Today I'm sharing the latest in a series of papers looking at the weather on other worlds, in this case bringing you the weather report from a nearby T-dwarf, SIMP-0136. 🪐

ICYMI: 📰 The Leverhulme Trust September Newsletter is out!

Thrilled to share that I’ve been awarded a 3 year Leverhulme ECF!

I’ll use global modeling with high-res regional ‘nests’ to take a closer look at Jupiter’s polar vortices.

As part of the project, I’ll incorporate this functionality into Isca (via a new dynamical core).

Very excited to begin!

Congrats @timlichtenberg.bsky.social !! For the Early Science Award by the @europlanetmedia.bsky.social super well deserved and amazing talk 🤩🥳🥳🥳!

Great article from the Simons Foundation about the open source MESA stellar evolution code, which has a had a huge impact on astrophysics over the past 15 years.
I had not heard that the code's architect, software guru Bill Paxton, had passed away in July.

Exoplanets 🔭 and Planetary Science 🪐 : Two Different Worlds 🌍 ?

What can planetary scientists learn from exoplanet research? Read all about it in our interview with @timlichtenberg.bsky.social

At a planet formation seminar today, the speaker used these amazing maps of the Solar System from Eleanor Lutz: she has a great blog post on how she took 18000 asteroids, on a log(size) and log(orbit) plot, with 40-year orbit trails, to create this #planetsci #dataviz

Two postdoc jobs available on our Arctic Butterflies project! (Not actual butterflies - basically Arctic dynamics and predictability - the butterfly effect in the Arctic...)

Oxford job: tinyurl.com/yc6h4b35

Reading job: tinyurl.com/ypn75jh2

Please help spread the word!

I updated my website to have an interactive webpage where you can plot the exoplanet population, select different parameter spaces to explore, and overlay the observed and planned JWST observations. I think this will be a useful tool for proposal planning: www.astrojake.com/exoplanets

Predictions of climate change are uncertain. That’s why we need to keep finding out how our atmosphere works, says Tim Palmer

📢📢 New preprint alert! 📢📢

Radiation is a key piece of climate models, but comes with a trade-off: use an accurate scheme (which is difficult to understand), or a simple scheme (which is not very accurate)...

Here I introduce a scheme which bridges this gap!

arxiv.org/abs/2508.09353

Under climate change, the polar regions warm *faster* than the rest of the world ("polar amplification", PA).

But, is this always the case?

In this preprint (with Tim Merlis) we studied the 'state-dependence' of PA—feedback welcomed! :)
