Abstract
The surface-layer flux-profile formulae of Louis (1979), used in many atmospheric models, are modified in a simple way to allow for differen t values of the roughness lengths for heat and momentum. The modified set of formulae simplifies the calculation of surface-layer fluxes ove r most natural land surfaces, where the roughness length for momentum can be almost an order of magnitude greater than that for heat.
