Objectives and Content


This course aims to give students the background for a basic description of turbulence and mixing in the boundary layer of atmosphere and ocean, and for assessing the relative importance and relevance of turbulence in processes related to meteorology, oceanography and climate.


An introduction to turbulence and turbulent exchange processes in the atmospheric boundary layer and the ocean mixed layer is given. The course covers homogenous turbulence theory, 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 are derived, and the different terms are discussed. Various theoretical models based on simplifications of the budget equations are introduced and their practical importance for measurement and data analysis is highlighted. Air-sea and air-sea-ice interactions are briefly discussed together with the turbulence beneath sea ice. The vertical profiles of temperature and velocity, and their turbulent fluxes are described and discussed for different forcing conditions. An overview of the common instruments and measurement methods is given.


Bachelor in meteorology and oceanography, Bachelor's degree in Climate, Atmosphere and Ocean Physics or equivalent programs.
