AIFS is based on a graph neural network (GNN) encoder and decoder, and a sliding window transformer processor,

and is trained on ECMWF’s ERA5 re-analysis and ECMWF’s operational numerical weather prediction (NWP) analyses.

It has a flexible and modular design and supports several levels of parallelism to enable training on

high resolution input data. AIFS forecast skill is assessed by comparing its forecasts to NWP analyses

and direct observational data.

We show that AIFS produces highly skilled forecasts for upper-air variables, surface weather parameters and
