• Roughness — is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small the surface is smooth. Roughness is typically… …   Wikipedia

• Roughness Length — (z 0) is a parameter which is a measure of terrain roughness as seen by surface wind. It is formally the height (in meters) at which the wind speed becomes zero when the logarithmic wind profile above the roughness sub layer is extrapolated to… …   Wikipedia
