Program Overview

Turbulent Boundary Layers in the Atmosphere and Ocean

The atmospheric boundary layer is the part of the atmosphere that is directly influenced by the surface of the Earth. The layer is turbulent and heat, moisture, momentum as well as other constituents are effectively transported and mixed in this layer. It is also where we live and the prime climate variable near surface temperature is found.

This course introduces the structure of the atmospheric turbulent boundary layer and the similar layers that are found in the ocean. Some turbulence theory as well as empirical methods to analyse and understand these layers are covered. What controls the depth of the layer and how turbulent it is as well as the efficient mixing and turbulent transport is discussed. How these processes influence the dynamics on the meso- and synoptic scales as well as the general circulation of the atmosphere and ocean are also considered. Methods on how to solve problems related to the boundary layer as well as how it is observed and modeled are also covered in the course as well as providing concepts to understand how pollutants are dispersed.

Course Structure

The course starts with introduction to turbulence and how a boundary layer is defined. The equations of motion are derived for the layer using Reynolds averaging. Similarity theory for the lowest part of the boundary layer, the surface layer, is introduced and established through empirical data. The influence of stability and rotation is discussed as well as the influence on the larger scales and dispersion.

Teaching Format

The course is composed of lectures and exercises and two labs, one with observations of primarily the near surface wind and one where the diurnal cycle of near surface variables and the boundary layer structure are studied using a single-column model.

Course Materials

Grading criteria, course literature and other materials and correspondence related to the course will be available on the course site once you have registered for the course.

Assessment

The examination is done by a written exam. Grading is done on a seven-step scale:

• A = Excellent
  • B = Very good
  • C = Good
  • D = Satisfactory
  • E = Sufficient
  • Fx = Failed, some more work is required
  • F = Failed, a lot more work is required

For passing the course, at least grade E is required, as well as passed written presentations of laborations and participation in all compulsory teaching.

Schedule

The schedule will be available no later than one month before the start of the course.
