WebWind is usually measured by its speed and direction. Wind atlases show the distribution of wind speeds on a broad scale, giving a graphical representation of mean wind speed (for a specified height) across an area. They are compiled by local meteorological station measurements or other wind-related recorded data. WebAverage wind speed increases as the elevation rises meter by meter and reduces the braking effect of hills, vegetation and other ground-based barriers. For this reason, state-of-the-art wind power systems now have hub heights of between 120 meters and 160 meters.
