Lecturer: Univ.-Prof. Dr. Fabian Hoffmann (f.hoffmann@fu-berlin.de).

Admission Requirements: keine.

Qualification Objectives: Students understand the complex nonlinear scale interactions in the atmosphere. They are familiar with the problem of parameterization of subscale phenomena using the example of important turbulence and friction processes and can independently apply the parameterization technique for modeling.

Contents: Discussion of non-geostrophic balanced internal and external gravity waves and their significance for weather forecasting and climate dynamics. Derivation of the spectrum of internal gravity waves, introduction to the theory of the atmospheric boundary layer and the energetics of subsynoptic turbulent processes. Discussion of averaging methods, similarity theory, and the problem of parameterization; derivation of the logarithmic wind profile and its diabatic generalization in the Prandtl layer; derivation of the Ekman spiral and friction-induced secondary circulation.
