Vertical velocity
The remaining diagnostic
is the vertical velocity, which is expressed for a given
hybrid-pressure level as
where
the derivative
term in Eq. 52
varies only with height and
is obtained using Eq. 60. Note that the
vertical velocities at the upper
and lower boundaries are equal to zero:
i.e.
.
Note that currently the contribution of
is neglected since this the contribution
is quite small and it is constant in space (it is simply a domain scale bias correction if
activated). But if moisture effects were included, the
term
would need to be retained in this computation.
