Here we present the first GCM that combines a differentiable solver for atmospheric dynamics with ML components, and show that it can generate forecasts of deterministic weather, ensemble weather and climate on par with the best ML and physics-based methods.

Machine learning emulation of gravity wave drag in numerical weather forecasting

no code implementations20 Jan 2021 Matthew Chantry, Sam Hatfield, Peter Duben, Inna Polichtchouk, Tim Palmer

By training on an increased complexity version of the existing parameterisation scheme we build emulators that produce more accurate forecasts.
