(Partially) Google Research's/DeepMind's NeuralGCM is based on hybrid models using ODEs and learnt physics: https://www.nature.com/articles/s41586-024-07744-y
Microsoft Research's Aurora on vision transformers: https://www.microsoft.com/en-us/research/blog/introducing-au...
Huawei's Pangu Weather is also a 3D transformer I believe https://www.nature.com/articles/s41586-024-07744-y
I just wanted to highlight that there are multiple approaches in use for the same problem / in the same domain, and GNN does not seem to be the most widely used one.
