Vertical profiles of electrical conductivity in the lowermost part of the turbulent boundary layer over flat ground

Results of experimental investigations and a theoretical estimation of the polar conductivity profiles in the turbulent surface layer over flat ground are discussed. The results presented are evidence for the occurrence of the steady electrode effect over land. By reducing the number of factors which influence the vertical conductivity profile and applying a special measuring technique, it has been possible to obtain steady profiles.The experimental results are in good agreement with the hypothesis of a turbulent electrode effect in the boundary of strong turbulent mixing. The agreement implies the confirmation of the relation between the surface wind, the electrical conductivity and the thickness of the electrode-effect layer.
