Geophysical fluid dynamics is a research area focused on the theoretical, computational, and observational study of fluid motion on planetary scales, where rotation, stratification, and spherical geometry strongly influence dynamics. It analyzes the behavior of atmospheres, oceans, and planetary interiors using the Navier–Stokes equations under approximations such as the Boussinesq, shallow-water, and quasigeostrophic models. Key processes include geostrophic and hydrostatic balance, baroclinic and barotropic instability, wave–mean flow interaction, and turbulence in rotating stratified fluids. The field underpins quantitative understanding of large-scale circulation, climate dynamics, and variability in geophysical and astrophysical fluid systems.
AI has created a sea change in society; now, it is setting its sights on the sea itself. Researchers at Osaka Metropolitan University have developed a machine learning-powered fluid simulation model that significantly reduces ...
