🌩️ Excited to share my work on Jacobian-Enforced Neural Networks (JENN)! JENN fills the gap between ML weather models & data assimilation, enhancing sensitivity (Jacobian) accuracy without compromising forecasts. A game-changer for tools like GraphCast, Pangu & NeuralGCM! 🌍 #ML #WeatherForecasting

ML weather models like GraphCast & NeuralGCM show promise in weather forecasting, but can they be used for data assimilation? Our study looks into their tangent linear & adjoint models, finding challenges in robustness & unphysical noise. 🌦️ #AI #NWP arxiv.org/abs/2411.14677
