Development of Multiscale Atmospher-Ocean coupeled Model and its Application to Society
Meteorological phenomena are made up of a complex interaction of phenomena at various spatial and temporal scales. It is necessary to develop a multi-scale model that can capture the interaction between multiple scales, because phenomena at multiple scales influence each other, rather than each scale existing as a single scale.
We will participate in the development and social application activities of a multi-scale atmosphere-ocean coupled model called MSSG (Multi-Scale Simulator for the Geoenvironment). The development of this MSSG model was started at JAMSTEC, and Associate Professor Onishi has been one of the main developers since 2005. There is a research project to be carried out in collaboration with the MSSG group at JAMSTEC (Associate Professor Onishi is the group leader until 3/2020).
