arXiv:2606.00281v1 Announce Type: cross Abstract: Generative machine learning is an increasingly important complement to dynamical downscaling for producing high-resolution precipitation projections, with diffusion models currently the leading approach. Flow matching is a related generative framework that has recently achieved strong results across image, video and other domains, and shown early promise for downscaling. We train a flow matching model to map daily precipitation from 8 km to 2 km over a convective-scale domain centred on Singapore, and benchmark it against CPMGEM, a score-based
The increasing sophistication of generative AI models, particularly flow matching, is enabling new applications in complex scientific domains like climate modeling, moving beyond traditional diffusion models.
Improving the accuracy and efficiency of high-resolution precipitation projections is critical for climate adaptation, infrastructure planning, and disaster preparedness in vulnerable regions.
Flow matching is emerging as a potentially superior or complementary generative AI technique for downscaling precipitation data, potentially offering more precise climate impact assessments.
