Key Findings
- 01Roughness length varies depending on the measurement method (wind profile, gustiness, drag coefficient) and height within the atmospheric boundary layer.
- 02Momentum and heat flux decrease significantly with height in non-homogeneous terrain, indicating that standard surface layer similarity relations are not directly applicable.
- 03Local scaling can still describe wind speed gradients using functions applicable to homogeneous surface layers, even in the presence of distant roughness transitions.
