The scaling factors to the model equations needed to account for
spherical geometry have been added to QTCM1, beginning with v2.0.
These terms are controlled in subroutine parinit. Variable
cosu is the cosine factor at each ``whole
gridpoint'' latitude location, i.e.
where the u variable is defined on the C-grid
(Table 
). Variable cosv is the same
at the ``half-grid'' locations, i.e. where the v variable is
defined on the C-grid. To remove spherical geometry effects, set both
cosu and cosv to 1.
