Variational Formulation of Fluid and Geophysical Fluid Dynamics

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.

“This book is mainly about derivations. For this reason, it is well suited for self-study and could be used in an advanced graduate course focused on variation methods and fluid mechanics. The material covered in this book should appeal to graduate students, postdocs, professors, and research scientists in physical oceanography, applied mathematics, applied physics, atmospheric dynamics, and ocean engineering.” (Colin R. Meyer, Pure and Applied Geophysics, Vol. 175, 2018)
