701-0479-00L | Environmental Fluid Dynamics | 3 credits | 2G | H. Wernli, M. Croci-Maspoli | |

Abstract | This course covers the basic physical concepts and mathematical equations used to describe environmental fluid systems on the rotating Earth. Fundamental concepts (e.g. vorticity dynamics and waves) are formally introduced, applied quantitatively and illustrated using examples. Exercises help to deepen knowledge of the material. | ||||

Objective | Students are able - to name the bases, concepts and methods of environmental fluid dynamics. - to understand and discuss the components of the basic physical equations in fluid dynamics - to apply basic mathematical equations to simple problems of environmental fluid dynamics | ||||

Content | Basic physial terminology and mathematical laws: Continuum hypothesis, forces, constitutive laws, state equations and basic principles of thermodynamics, kinematics, laws of mass and momentum on rotating earth. Concepts and illustrative flow sytems: vorticity dynamics, boundary layers, instability, turbulence - with respect to environmental fluid systems. Scale analysis: dimensionles variables and dynamical similarity, simplification of the fluid system, e.g. shallow water assumption, geostrophic flow. Waves in environmental fluid systems. | ||||

701-1221-00L | Dynamics of Large-Scale Atmospheric Flow | 4 credits | 2V + 1U | H. Wernli, S. Pfahl | |

Abstract | Dynamic, synoptic Meteorology | ||||

Objective | Understanding the dynamics of large-scale atmospheric flow | ||||

Content | Dynamical Meteorology is concerned with the dynamical processes of the earth's atmosphere. The fundamental equations of motion in the atmosphere will be discussed along with the dynamics and interactions of synoptic system - i.e. the low and high pressure systems that determine our weather. The motion of such systems can be understood in terms of quasi-geostrophic theory. The lecture course provides a derivation of the mathematical basis along with some interpretations and applications of the concept. | ||||
