My thoughts on the crucial importance of methodology on self-reported AI performance on mathematics competitions, and my policy on commenting on such reports going forward: mathstodon.xyz/@tao/1148814...

To celebrate the kick-off of #UNOC3 and #OOSC in Nice, we share a striking, mesmerising perspective on Mediterranean Marine Heatwaves —and their clear amplification by climate change.

🌪️ Typhoon spotted in a global 4.4km IFS-FESOM run.
Visualizing cloud structures using only model data — aiming to match the look of satellite imagery. Impressive how close simulations can get.

For a new visualization project @awi.de, I’m currently experimenting with satellite imagery, elevation data, and OSM. Exciting!

Exploring ways to visualise wind together with my colleague @sbeyer.net at AWI. Here’s a glimpse: IFS-FESOM wind speed visualised as coloured particles.

🌍🌐 What if we could replay recent extreme weather under different climate conditions? With storyline simulations in the EU’s #DestinE initiative, scientists are reconstructing past, present, and future extreme weather to help us adapt to climate change.

Experimenting a little bit with #blender particle systems and simulated wind data

Sea ice meets ocean eddies, part II!
Folllowing @oceanographer.bsky.social's idea I used the data from my simulation (still #FESOM2 but 10km this time) to explore the flames of the frozen ocean. 🧊 🔥

First post on @bsky.app 🎉:

Can #AI-based weather forecasting models (trained on present-day data) provide skillful forecasts also in different colder and warmer states of the climate system?

Our preprint in arxiv explores this question:

Here is what we found so far (🧵1/7)

To celebrate Antarctica Day, here is an image of winds around Antarctica as simulated by a 4 km resolution atmospheric model. 🧪

Model: IFS-FESOM | Shown: U component of wind | Project: nextGEMS #SciArt

The storyline approach isn’t new, but for the first time, we’re using it with 10km resolution! 🌍 See how extreme events might have looked in the past, without climate change, and how they could unfold in a +2°C future. Check out our work led by Amal John: essopenarchive.org/users/852952...
