They achieve the first real -time prediction of tile associated with typhoons using the Fugaku supercomputer

Fujitsu Limited and the National University of Yokohama (Japon) have achieved the first real -time prediction of the world of multiple tornadoes associated with typhoons using the advanced technology of the Fugaku supercomputer.

Tornados are hard -to -predict meteorological phenomena due to their small scale and short duration. Japan began broadcasting alerts in 2008, but these currently have a period of validity of approximately one hour. This is binding that in this Asian country approximately 20 percent of tornadoes are produced along with typhons

Fujitsu and the National University of Yokohama initiated a joint research project in November 2022, with the objective of address social challenges related to typhons More and more severe exacerbated by global warming, as they report in a press release.

This collaboration, carried out within the frame Understand training mechanisms of the typhoons and in accelerate and improve the accuracy of simulations of prediction.

The new technology uses a Parallel processing on a large scale along with the ‘cloud resolving storm simulator’ (Cress) improved, a meteorological simulator developed by Professor Kazuhisa Tsuboki in the Fujitsu Fugaku supercomputer.

Cress, based on high precision weather simulations that cover from cloud scales (50m to 2,000m) to MesoScalas (horizontal 2km to 2,000km), precisely simulates the formation and development of supercellular thunderstorms They generate tornadoes.

However, the original design of this system was not adequate for parallel large -scale processing necessary for the prediction of tissues associated with typhoons, which gave rise to times of excessively long parallel calculation and made it inappropriate for prediction in real time . To solve this, it developed A light version of Cress, which reduced computational demands while maintaining the necessary prediction precision.

In addition, it was used The large -scale parallel processing technology of Fujitsuoptimizing the mapping of simulation processing for the Red Structure of Fugaku servers and implementing the superimposed execution of computing and file output. This reduced the simulation time in Fugaku, which allowed substantially faster prediction results than was previously possible.

Previously, during the simulations of Typhoon Typhons No. 10, which hit the Kyushu area in Japan in August 2024, it took more than eleven hours to predict whether or not they were madewhich made the predictions not applicable in practice.

This technology was able to reduce the prediction time to 80 minutes, which allowed the two partners predict the appearance of a tornado four hours in advance. This prediction calculation used only 5 percent of Fugaku’s computational resources, indicating the potential for even faster predictions and larger scale in the future.

The two partners will launch Cress improved to the investigating community in fiscal year 2024, to Improve the prediction of extreme meteorological phenomena and enhance disaster mitigation efforts.
