VERTICAL PROFILES OF ELECTRICAL-CONDUCTIVITY IN THE LOWERMOST PART OFTHE 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 f lat ground are discussed. The results presented are evidence for the o ccurrence of the steady electrode effect over land. By reducing the nu mber 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 stro ng turbulent mixing. The agreement implies the confirmation of the rel ation between the surface wind, the electrical conductivity and the th ickness of the electrode-effect layer.
