|
cr_width |
Width of the canopy in windless conditions (m). |
cr_depth |
Length of the canopy in windless conditions (m). |
spacing |
Mean distance between trees (m). |
uguess |
Critical wind speed at canopy top calculated with the roughness or single-tree method (m s-1). |
n_drag |
N parameter of the drag coefficient formula (dimensionless). |
c_drag |
C parameter of the drag coefficient formula (dimensionless). |
drag_upper_limit |
Maximum wind speed used during the experiments from which |
ht |
Height of the tree. In the 'roughness' method, this is stand mean height. In the TMC method, this is 'equivalent mean height' (m). |
z0
, the length (m) of the surface roughness of the tree canopy.
