Fujitsu & Yokohama National University Transform Tornado Forecasting
Revolutionary Tornado Prediction Technology Unveiled
Fujitsu Limited and Yokohama National University have made remarkable strides in the field of weather forecasting. They have successfully developed the world's first real-time prediction technology for tornadoes that are associated with typhoons. This groundbreaking achievement is a leap forward in disaster preparedness and response, leveraging the power of advanced supercomputing technology.
Utilizing Supercomputing for Enhanced Accuracy
The innovative technology integrates optimized large-scale parallel processing with the enhanced Cloud Resolving Storm Simulator (CReSS). This advanced weather simulator, developed by Professor Kazuhisa Tsuboki, takes advantage of the capabilities of the Fugaku supercomputer. By performing high-resolution simulations, it facilitates a comprehensive understanding of both large-scale typhoons and the smaller, more intense tornadoes that accompany them. This synergy of technology allows for timely and precise real-time predictions.
Radical Improvements in Prediction Time
Historically, predicting tornado occurrences associated with typhoons has posed significant challenges. For instance, during the previous evaluations of Typhoon No. 10's tornadoes in Japan, the prediction process was lengthily entailed, often exceeding 11 hours. This extensive timeframe made the practical application of forecasts challenging. However, with the new technological advancements, the prediction time has been significantly shortened to just 80 minutes. Moreover, this advanced calculation enables forecasts to predict tornadoes up to four hours in advance, providing timely alerts to those at risk.
Future Prospects of Weather Prediction
This new approach utilized merely 5% of the Fugaku supercomputer's computational resources, which opens doors for scaling up predictions on a larger scale with even greater speed. The collaboration between Fujitsu and Yokohama National University marks an important step in enhancing the accuracy and effectiveness of severe weather predictions.
Enhanced CReSS Release to the Research Community
As part of their continuing efforts in disaster management, the two partners plan to release the enhanced version of CReSS to the research community within the fiscal year. This release will surely empower more scientists, researchers, and meteorologists to improve their predictive capabilities and enhance disaster mitigation strategies.
Understanding the Tornado Phenomenon
In Japan, it is noted that about 20% of all tornado occurrences happen during typhoon events. The increasing damage and unpredictability of these tornadoes prompted Japan to begin issuing warnings in 2008. Still, tornadoes remain intricate phenomena to predict due to their less stable nature, brief duration, and small scale. The average validity of tornado warnings is approximately one hour, signaling a need for their enhancement.
The Importance of Continued Research
Fujitsu partnered with Yokohama National University in a collaborative research project that commenced in November 2022. This effort seeks to tackle the societal challenges posed by increasingly severe typhoons, which are becoming more frequent due to global warming. The research focuses on understanding the mechanisms behind typhoon formation while working towards improved accuracy in their predictions.
Conclusion
The partnership between Fujitsu and Yokohama National University stands as a pioneering move in the realm of weather prediction. By harnessing the power of supercomputing, they are setting a new standard in forecasting technologies aimed at saving lives and enhancing disaster preparedness.
