f(Richardson Number) |
The aerodynamic resistance is estimated as a function of Richardson number. |
|
f(Monin-Obukhov Length) |
The aerodynamic resistance is estimated as a function of the Monin-Obukhov stability parameter (zref-d)/LO. Richardsons number is transformed into the Monin-Obukhov parameter by an iterative procedure which may slow down the simulations. On the other hand, variations of surface roughness for momentum and heat are treated in a consistent way. |
