701-0479-00L | Environmental Fluid Dynamics | W | 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. | |||||

651-3561-00L | Cryosphere | W | 3 credits | 2V | M. Funk, M. Huss, K. Steffen | |

Abstract | This course introduces the different parts of the cryosphere - snow, glaciers, sea ice, permafrost - and their role in the climate system. A significant physical aspect is the focus in each part. Those completing the course are able to describe the dynamics of cryosphere components both formally and using examples. | |||||

Objective | Students are able - to qualitatively describe the main components of the cryosphere and their role in the climate system - to formally describe the relevant physical processes which determine the state of cryosphere components | |||||

Content | Introduction into the different components of the Cryosphere: Snow, glaciers, sea ice and permafrost, and their roles in the climate system. Each part is use to emphasized on one specific physical aspect: material qualities of ice, mass balance and dynamics of glaciers and energy balance of sea ice. | |||||
