According to Nature ML methods are starting to outperform NWP without supercomputers https://www.nature.com/articles/d41586-023-03552-y and the coolest thing is that they already released the code https://github.com/google-deepmind/graphcast so I wonder how long would it take before we start seeing people pull data from home weather stations to run an hyperlocal fine-tuned model.
The bitter lesson strikes again.
