Supercomputer System

The Meteorological Research Institute (MRI) supercomputer system is currently operated for numerical studies on atmospheric, oceanic, seismic and volcanic phenomena using various numerical models/systems. The models and systems used help to clarify the details of atmospheric disturbances such as torrential rainfall events and typhoons as well as seismic and volcanic phenomena such as earthquakes and eruptions. They also support the improvement of numerical prediction and the clarification of climate change.
