Continuous measurements of wind were made throughout a layer extending from the surface to a depth of 12m over a distance along the direction of the wind of about 150 metres. It has been found that the variation in the elevation of the underlying terrain has a profound effect, larger than that of the variation in surface roughness. The shape of the downwind profiles is consistent with the prediction of second-order-closure change-of-roughness models. Another observational site has been selected for comparison and the study of flow over non-uniform terrain is continuing.
