    14631463Upper limit of the flux-Richardson number.\\\\
    1464 With the Prandtl layer switched on (see [#prandtl_layer prandtl_layer]]), flux-Richardson numbers ('''rif''') are calculated for z=zp (k=1) in the 3d-model (in the [[1d-model]] for all heights). Their values in particular determine the values of the friction velocity (1d- and 3d-model) and the values of the eddy diffusivity (1d-model). With small wind velocities at the Prandtl layer top or small vertical wind shears in the 1d-model, '''rif''' can take up unrealistic large values. They are limited by an upper ('''rif_max''') and lower limit (see [#rif_min rif_min]) for the flux-Richardson number. The condition '''rif_max''' > rif_min must be met.
