Is this somehow related to the Google weather prediction model using AI [1]? https://deepmind.google/discover/blog/graphcast-ai-model-for-faster-and-more-accur

  No, Graphcast is a graph transformer trained on ERA5 weather reconstructions of the atmosphere, not a general time series prediction model. It by the way outperforms all traditional global point forecasts (non-ensembles), at least on predicting large-scale global patterns (Z500 and such, on the lag of 3–10 days or so). ECMWF has AIFS that is a derivate of Graphcast, they'll probably get it or something similar to production in a couple of years.

    AIFS is transformer based (Graphcast is pure GNN) so different architecture and is already running operationally, see: https://www.ecmwf.int/en/about/media-centre/aifs-blog/2024/its-raining-data https://www.ecmwf.int/en/about/media-centre/aifs-blog/2024/i...
