Experimental results concerning turbulence in a coastal zone are presented. The presence of internal boundary layers and advection in complex terrain precludes the use of Monin–Obukhov similarity theory ( MOST ) to estimate effective values of the turbulent transport (of momentum and heat) parameters. However, the use of local Monin–Obukhov similarity is less restrictive: if an analogy is made between the stability integrated functions for horizontally homogeneous terrain and a corresponding term in complex terrain, effective values of the Obukhov and roughness lengths can be obtained using sonic anemometry.
