Researchers have developed a diffusion-based generative model for global sea state estimation, which conditions on five days of wind forcing data. This model directly samples the sea state distribution, extending beyond bulk variables to include partition-related quantities like Stokes drift. Trained on a 30-year hindcast, the diffusion model offers significant computational acceleration over traditional spectral wave models while maintaining skillful predictions and calibrated ensemble spreads for bulk variables.

IMPACT This diffusion model could enable more efficient and probabilistic wave forecasting, integrating sea state information into broader earth system models.
