Japan Meteorological Agency renews central systems such as “AMEDAS” –Starts integrated operation on virtualization platform

The Japan Meteorological Agency has renewed three systems, including the “Regional Meteorological Observation System” (AMEDAS), and moved to the “Meteorological Agency Information System Platform”, a virtualization platform for integrated operation of all systems. The operation started in March. Fujitsu was in charge of the construction of the Japan Meteorological Agency information system infrastructure and the renewal and migration of the central system. With this platform, the operation management system of each system can be unified, cost reduction, system sophistication, and stable 24-hour non-stop operation are realized by unifying security standards. Since it is operated on the same platform, it is said that it will be possible to shorten the development period of new functions and new systems, facilitate cooperation with other systems, and accelerate the use and utilization of data.

Until now, the Japan Meteorological Agency has prepared systems for each business in addition to these systems, and has operated the systems in two east and west stations in a distributed manner in preparation for a large-scale disaster. However, there have been problems such as increased operating costs, complicated operation management, longer development periods for new systems, and delays in adapting to the latest technologies. In order to solve these issues, the platform has been introduced and each business system has been gradually migrated since October 2020. With this transition to the system infrastructure, AMeDAS will be able to flexibly add system resources in response to the increase in the amount of meteorological observation data due to the recent localization and intensification of disasters, and will be able to promptly and accurately announce disaster-prevention weather information. Can contribute. Due to the transition, Ades will significantly improve the data processing capacity of Ades, which is required due to the increase in meteorological observation data collected from AMeDAS, tide level data integrated processing system, meteorological satellites, etc. and the improvement of computing power of supercomputer systems. It enables accurate and agile distribution of weather information that is updated one by one. The tide level data comprehensive processing system aggregates and processes the observed tide level data, distributes real-time information on storm surges and tsunamis, and exchanges data with external organizations. This shift to the system infrastructure will contribute to the safe and real-time distribution of data essential for storm surge warnings and warnings caused by earthquakes, tsunamis, and typhoons.
