Geophysical Fluid Dynamics (GFD) is dealing with various aspects of the mathematical descriptions of rotating stratified fluids starting from the physical laws of hydro-thermo-dynamics. Historically, Physicists and Mathematicians originating from various disciplines developed physical and numerical models with increasing complexity, adding to our fundamental understanding of such flows and thereby unifying these fields. Today GFD is a truly interdisciplinary field of its own, which encompasses multiscale flows of planetary atmospheres and oceans, their weather and climate, and the motions of 'the solid Earth'.

In this session we invite contributions expanding our understanding of the complex behavior of geophysical flows, presenting novel techniques that either facilitate a deeper understanding or improve the efficacy of numerical procedures involved, and/or reviewing major advances in a particular aspect of geophysical fluid dynamics. The interdisciplinary character of dynamical and computational aspects of this session encourages an exchange of ideas and contributions across various fields, such as meteorology, oceanography, astrophysics, geological fluid dynamics, applied mathematics, and computational fluid dynamics with applications to ocean and atmosphere.

In particular we invite contributions on the role of waves in stratified geophysical flows and the understanding of multiscale phenomena. Multiple-scale wave interactions are pivotal for the understanding and prediction of weather and climate variability and extreme weather events.
