Aim and Content
An introduction into turbulence and turbulent energy fluxes in the atmospheric boundary layer and the ocean mixed layer is given in this course. This introduction is intended to provide a basis for further advanced studies in this field. It also aims to give students a sufficient background for assessing the relative importance and relevance of turbulence in other issues related to meteorology, oceanography or climate. The course covers homogenous turbulence theory including spectral descriptions, definition and measurement of turbulent fluxes and the influence of stratification in the boundary layer in the atmosphere and in the ocean. The budget equations for the turbulent kinetic energy and the temperature variance are derived and the different terms are discussed. Salient features of various processes in the oceanic mixed layer and the atmospheric boundary layer are introduced. The profiles of tracers and velocity and their turbulent fluxes in the atmosphere and in the ocean are described and discussed in different forcing conditions. An overview over the common instruments and measurement methods is given.
