Dr. Gualtiero Badin is professor at the Universität Hamburg (Germany). He is specialized in geophysical fluid dynamics, ocean dynamics, especially at frontal scales, geostrophic turbulence and nonlinear dynamics.

Dr. Fulvio Crisciani is lecturer at the University of Trieste (Italy). He has more than 32 years experience in oceanography and is specialized in geophysical fluid dynamics and the climate of the gulf of Trieste.

Emphasizes a subject matter of interdisciplinary interest for meteorology, oceanography, physics and applied mathematics

Provides a detailed derivation of the equations of motion from conserved quantities and from system symmetries

Focuses in particular on the analysis and consequences of particle relabeling symmetry

Applies results to different approximations, such as the semi-geostrophic equations, and different relations, such as the conservation of wave activity
