In this course the basic elements of fluid dynamics in both inertial and rotating reference frames are introduced. The aim is to allow the student to deal with practical problems concerning oceanic and atmospheric fluid dynamics, offshore hydrodynamics and aircraft aerodynamics. The discussion of analytical aspects is always accompanied by a detailed description of the corresponding phenomenology.
