Description :
This article focuses on the landscape scale of the soil-vegetation-atmosphere exchange. After a brief sketch of flux-gradient relations over homogeneous vegetation an outline will be given of the classical ideas on the flow of air across vegetation boundaries. Then it reports on the rate at which the thickness of a new equilibrium internal boundary layer downwind of a roughness change builds up. This rate is found to be one order of magnitude larger over forest as compared to lower vegetation. Recently acquired experimental evidence appears to some extent contradictory and at variance with conventional concepts.
