SimCast‑S2S is a generative latent‑diffusion model designed for probabilistic subseasonal‑to‑seasonal precipitation forecasting. It tackles three key challenges: it uses a diffusion pipeline to capture uncertainty, operates in a compact latent space to enable efficient large‑ensemble generation, and leverages transfer learning with low‑rank adaptation to train on limited reanalysis data after pretraining on climate simulations. The model outperforms deep‑learning baselines and competes with, or surpasses, operational systems such as the ECMWF‑S2S baseline without requiring extensive post‑processing.
SimCast‑S2S is a generative latent‑diffusion framework designed for probabilistic subseasonal‑to‑seasonal precipitation forecasting. It tackles three key challenges: it uses a diffusion‑based generative pipeline for uncertainty quantification, operates in a compact latent space learned by VAEs for efficient large‑ensemble generation, and employs transfer learning with LoRA to overcome limited training data. On reanalysis data, it outperforms deep‑learning baselines and competes with or surpasses state‑of‑the‑art operational systems such as ECMWF‑S2S.

The paper introduces Climate Physics Dynamic Matching (ClimPhyDM), a variational, simulation‑free framework that blends an advection‑type physics prior with data‑driven components for weather forecasting. It leverages deep generative models to capture complex dynamical systems while preserving underlying physical structure. On the ERA5 benchmark, ClimPhyDM outperforms existing methods such as ClimODE and GB‑DM, achieving lower error over extended horizons and demonstrating improved temporal stability and resistance to error accumulation, all while training on a single modest 12 GB consumer GPU.
