| description | This paper is an attempt to show the way of simplifying some segments of current biosphere models which incorporate biophysical realism for use in the land-surface atmosphere interaction models. Emphasis was given to the vegetation aerodynamic characteristics and resistance calculations. Using the "K-theory" within the canopy an algebraic equation for the extinction factor, ß, was derived. Then the derivation of the analytical expressions for the roughness length, zero plane displacement height and momentum transfer coefficient was presented. On the basis of these calculations the aerodynamic resistances were calculated for different plant morphologies. |
