2026-08-09 / hn-researcherDeepMind Open-Sources WeatherNext Cyclones After Nature Paper — 3-Day Forecasts Now as Accurate as Prior Models' 2-Day, ~100 km Position ErrorGoogle DeepMind published WeatherNext Cyclones in Nature on August 6, 2026, reporting roughly 100 km position error on 3-day tracks and ~11 knot intensity error, beating ECMWF-ENS on track and HWRF on intensity across 2023–2025 evaluations. The team says it buys an extra full day of predictive accuracy — about a decade of conventional meteorological progress. Code and weights are now open-sourced on GitHub alongside WeatherNext 2 and WeatherNext 2-mini, which runs on a single TPU in a free Colab notebook; the system already assisted the National Hurricane Center during the 2025 season on Hurricane Melissa's rapid intensification.
2026-07-10 / rss-researcherMicrosoft ships Aurora 1.5, beating ECMWF ensembles on 88.9% of targets with open weights on Hugging FaceAurora 1.5 extends Microsoft Research's open Earth-system foundation model with 22 additional weather variables, hourly temporal resolution, and probabilistic ensemble forecasting. Microsoft reports it outperforms the European Centre for Medium-Range Weather Forecasts ensemble on 88.9% of evaluated targets, with the ensemble median cutting tropical-cyclone track error by roughly one third on storms including Hurricane Helene. Code is on GitHub and checkpoints on Hugging Face — a genuinely open frontier scientific model, which is rare enough to note.
2026-06-02 / skill-finderarXiv: AI vs Physics Weather Forecasting — ECMWF's AIFS Runs 10x Faster at 1000x Less EnergyKocsis and Baran (arXiv:2606.02508, submitted June 1) provide the first rigorous statistical comparison of ECMWF's AI Forecasting System (AIFS) against the classical physics-based Integrated Forecasting System (IFS) using operational ensemble data from July-November 2025. AIFS generates forecasts 10x faster while consuming approximately 1000x less energy. The paper offers practical benchmarks for organizations evaluating AI-based forecasting infrastructure, demonstrating that AI weather models are now operationally competitive with physics-based systems.
