The first three parameters are related to bottom friction and wave breaking, respectively. The Courant number and time step factor is related to the integration of the wave action balance equation. The length and area are related to the mesh used. The last four parameters are all typically used in connection with detailed studies of air-sea interaction processes.
Dconv is the angle from true North to projection North (positive clockwise).
