Wind profiles through the stable boundary layer are presented. The data were collected at a site located in a shallow river valley and show evidence of upstream effects near the edge of the valley. The wind‐speed profiles are consistent with a non‐dimensional shear Ø m = 1 + 3z/ L for z/L < 0.5. Changes in wind speed and direction are found to occur over a greater depth than the depth of the turbulent nocturnal boundary layer estimated from various diagnostic formulae.
