AN ANALYSIS OF SOME WIND PROFILES IN THE ATMOS PHERIC FRICTION LAYER,

Abstract

In the layer of atmosphere between the surface and a level where the wind is close to the geo strophic (the 'friction layer'), the assumption is commonly made that the shearing stress and velocity gradient are parallel. Theoretical rea sons are advanced to indicate that this assump tion is probably not valid and some analyses of observed wind profiles made on this assumption are shown to yield unrealistic results. Although the analyses are open to some criticism on the basis of instrumental inaccuracy and lack of horizontal uniformity of the observing site, the general conclusion is reached that paral lelism of stress and velocity gradient cannot, in our present state of knowledge, be relied upon.
