Abstract: Accurate and reliable weather and climate prediction is vital for societal planning, disaster mitigation, and understanding climate change. The increasing frequency of extreme weather events demands robust probabilistic forecasts that effectively quantify uncertainty. While generative models, particularly diffusion models, offer a promising path, methodological innovations are needed to overcome crucial limitations in their computational and data efficiency for these large-scale problems. In this talk, I will discuss methodological advancements that address these efficiency bottlenecks by explicitly leveraging the temporal structure of the data to design more efficient generative models for forecasting and emulation problems
