Geophysical Fluid Dynamics
Session ID#: 77903
Session Description:
The purpose of this session is to gather scientists interested in all aspects of the fluid mechanics of the Earth and planets - including oceans, atmospheres and interiors - and to favor exchanges between fluid dynamics and geophysics communities. Thanks to the evolution of high-performance computing, the progress in data acquisition techniques in laboratory experiments and the resolution achieved by modern "in-situ" and remote sensing instruments, research on fluid mechanics has become indispensable to gain knowledge on geophysical flows. Main topics of this session will be instabilities, energy cascades, mixing as well all the mechanisms underlying the dynamics of geophysical fluids, such as waves, turbulence, phase transitions and the coupling with magnetic fields and natural plasmas. Studies of rotating, stratified, helical, convecting and/or conductive fluids of geophysical interest are welcome. Contributions based on state of the art observations, numerical simulations, theoretical models and laboratory experiments will be all well received.
