In the advection diffusion equation of dust (
equation (20) in Part I), the advection term
is evaluated by the forth order centered
scheme 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
.
Representation of
,
and
are same as those of
(22), (24) and
(42).
