✦ Synopsis

Abstract

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.
