| スコープ | High-performance computing (HPC) supports today's weather, climate, and environmental research by enabling higher resolution, larger domains, ensemble simulations, and sophisticated physical processes. As computer architectures evolve, close collaboration between atmospheric and computational sciences has become increasingly essential. From FY2025, the design and development of Japan's next flagship machine following the supercomputer "Fugaku" has begun, requiring the active use of accelerators such as GPUs. HPC is also driving innovation in data science, where data assimilation using observation big data and AI integration has achieved remarkable progress. Co-hosted with the Meteorological Society of Japan, this session calls for research on weather, climate, and environmental science that focuses on "computation," including numerical modeling, big data analysis, data assimilation, and AI. Participants will share prospects and challenges for atmospheric science research using HPC.
This year, we will also hold a special session on the HANAMI project. Funded by the EuroHPC Joint Undertaking, this project unites European and Japanese researchers to address key scientific challenges through HPC. Its Work Package 4 focuses on weather and climate simulation, including reproducibility and verification of climate models, benchmarking of supercomputers, and advanced local cloud-resolving simulations. Beyond reporting HANAMI's achievements, we aim to explore next-generation collaboration opportunities between Europe and Japan-leveraging upcoming supercomputers to improve extreme weather prediction, reduce uncertainties in long-term projections, and contribute to societal goals such as disaster risk reduction and carbon neutrality. Through these discussions, we seek to strengthen international cooperation and establish a sustainable foundation for advancing computational atmospheric science. |
