A survey is given of previous theoretical investigations of the development of an internal boundary layer in turbulent flow over a surface of variable roughness. On the basis of Monin and Kazanski's plume propagation concept, a new formula is derived which predicts the growth of the internal boundary layer under diabatic conditions. Wind and temperature profiles observed in air flowing across an artificial pond on the surface of a sheet of sea ice (near Point Barrow, Alaska) are used to test the new model, and it is found to give at least a qualitative prediction of the features of the internal boundary layer. The direction in which further refinement of the theory seems promising is indicated. (Author)
