Abstract : D. L. Laikhtman in his work presented a new method of determining the eddy viscosity coefficient, k, in the boundary layer of the atmosphere from observations on the vertical wind profile. As M. P. Churinova's comparative experimental verifications of the various methods used in determining k have demonstrated, Laikhtman's method is the simplest and the most accurate. It must be noted, however, that the scheme of the calculations used by Churinova is still fairly complex and very time-consuming. This disadvantage can be avoided if the calculations are made graphically by means of a special nomogram. In connection with this, the possible methods of determining graphically the eddy viscosity coefficient from observations on vertical wind profiles are discussed in the present work. (Author)
