The paper presents some results of measurements of the turbulent diffusion coefficients in the atmospheric boundary layer. Experimental data prove the hypothesis on their proportionality to the corresponding components of the Reynolds stress tensor. Considerable deviations, in spite of general opinion, of the main tensor axes from the traditionally set coordinate system have been revealed. The effect of a step-wise change of the main axis position of the diffusion coefficients tensor in the vertical plane at some critical value of the Richardson gradient number is discussed.
