It is tempting to view the capability of current AI technology as a singular quantity: either a given task X is within the ability of current tools, or it is not. However, there is in fact a very wid...

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.

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:

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...
