AI and math for meteorology and climatology - Michael Brenner : The neural GCM, and other remarks

Michael Brenner

Harvard University, Research Scientist, Google Research

Résumé

I will discuss the Neural GCM, which we built by building a dynamical core in JAX and then training the parameterization on ERA5 on 5-day forecasts. The quality of the forecasts up to 1 year portends a potential revolution in improving model parameterizations of physical systems described by nonlinear partial differential equations, of which weather and climate models are only one example. I will discuss some other problems in this spirit we are working on and try to draw conclusions.
