B. Finite difference equations of the model
B.c. Dust transport In the advection diffusion equation of dust (A.19), the advection term is evaluated by the forth order centered scheme, same as the thermodynamic equation, and the vertical advection term associated with the gravitational settling is evaluated by the first order upstream scheme. In time integration, the forward scheme is adapted for the friction terms and the gravitational settling term. Descriptions of , , are omitted since those are same as (B.15), (B.17), and (B.35).
