Turbulences in the Atmospheric Boundary Layer and Their Consequences for Wind Field Models


Wind turbulence plays an important role in the use of wind energy. Previous approaches to describing turbulence have proven to be inadequate for maritime conditions, especially with regard to the near-surface, lower boundary layer. The main aim of the RAVE Veritas research project was the verification of turbulence parameterisation and description of the vertical structure of the marine atmospheric boundary layer. On the basis of measurements from the Fino 1 research platform it was possible to improve the near-surface turbulence description, to quantify the sea’s continuous evaporation process as a permanent source of moisture, and identify it as an important parameter for the stability of the atmospheric layer. With stable air stratification it is now possible to take the influence of the variable surface roughness of the sea, in other words with varying wave lengths and heights, into account in model calculations in the form of a resistance coefficient.
