Neural ODEs have surfaced in the last decade as a new perspective on modelling dynamics by learning the time-derivative that drives the system evolution forward as a neural network. While succesful on systems of limited complexity, large-scale demonstrations have been lacking. Recently large autoregressive transformer models have been developed with breakthrough global weather forecasting performances, but at times with little consideration of the underlying dynamics. We consider global weather as a continuous-time PDE with mass-preserving dynamics, and show how simple convolution networks can achieve remarkable weather prediction performance with just a few million parameters. This talk is based on the paper “ClimODE: Climate Forecasting With Physics-informed Neural ODEs” accepted for ICLR’24 oral presentation.
