    Abstract

    The report discusses the influence of inhomogeneous surface conditions on meteorological data from two neighbouring sites in Jutland. The difference in the averages of the wind speed at the two stations is attributed to dissimilarities in roughness in the area and is described by the use of similarity laws for the neutral planetary boundary layers and for the neutral surface boundary layer. In contrast, the difference in the averages of the wind direction is attributed to both momentum balance requirements with changing topographical height, and the differential heating and/or cooling within the area.
