Fujitsu Limited and Yokohama National University have achieved the world’s first real-time prediction of multiple typhoon-associated tornadoes using advanced supercomputing technology.
The new technology utilizes optimized large-scale parallel processing coupled with the enhanced Cloud Resolving Storm Simulator (CReSS), a weather simulator developed by Professor Kazuhisa Tsuboki on Fujitsu’s Fugaku supercomputer. This allows for a single, high-resolution simulations encompassing both large-scale typhoons and smaller-scale tornadoes, resulting in accurate, real-time predictions.
Fujitsu and Yokohama National University initiated a joint research project in 2022 to address societal challenges related to increasingly severe typhoons exacerbated by global warming. This collaboration, conducted under the Fujitsu Small Research Lab’s Fujitsu – Yokohama National University Typhoon Science and Technology Research Center Collaborative Research Laboratory, focused on understanding typhoon formation mechanisms and accelerating and improving the accuracy of typhoon prediction simulations.
Seishi Okamoto, EVP, Head of Fujitsu Research, Fujitsu Limited, said: “By advancing research in typhoon development prediction and prediction simulation, we aim to help mitigate weather-related disasters and lessen their impact, contributing to solutions for global environment, one of Fujitsu’s key materiality topics.
Professor Hironori Fudeyasu, Director, TRC, Institute of Multidisciplinary Sciences, Yokohama National University, said: “The supercomputer Fugaku and high-resolution modelling enabled high-precision simulations across scales, leading to real-time predictions crucial for improving early warning systems and mitigating the impact of these devastating events. This breakthrough is expected to significantly contribute to disaster risk reduction while minimizing environmental consequences.”
