Fujitsu provides supercomputer system to JMA for forecasting of linear rainbands and torrential rains in Japan
Fujitsu has provided a new supercomputer system to the Japan Meteorological Agency JMA) for use in linear rainband (also called stationary linear mesoscale convective systems) forecasting. The new supercomputer system is able to predict the occurrence of linear rainbands which can trigger heavy rain, leading to disasters like landslides and flooding. The new supercomputer system is based on the FUJITSU Supercomputer PRIMEHPC FX1000 hardware, which features the same A64FX CPU as the supercomputer Fugaku, jointly developed by RIKEN and Fujitsu.
The new supercomputer system consists of 24 racks (12 racks each for the main and sub systems), and reaches a theoretical peak performance of about 31.1 PFLOPS. The storage system consists of high-speed storage with a total capacity of 42.3 petabytes. Heavy rains are often triggered by linear rainbands, a weather phenomenon that can occur when cumulonimbus clouds slowly move or remain for several hours over the same area.
The new system will be installed at a data center of Fujitsu, which is equipped with safeguard mechanisms against various disasters including earthquakes and flooding to support business continuity through stable operation management around the clock. With the new system, Fujitsu will support the JMA in its efforts to provide more accurate and rapid forecasts, allowing authorities to improve preparedness for heavy rain events and offer earlier warnings in case of disasters. The JMA will start operations of the new system on March 1, 2023.
