[gradsusr] Computation of Pressure Gradient

[Djordje Romanic]

Hi,

I have asked a similar question a few days ago. Here is the answer provided
by Jeff Duda:

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The pressure gradient is simply 1/rho * del(p), where del(p) is the
gradient operator, which can be displayed in Grads using the mathematical
decomposition of the gradient operator (i.e., derivatives in the x- and
y-directions).  Use cdiff for those derivatives.  Note, you'll have to
define your x- and y- grid spacing values as well.  See the examples
on the cdiff
help page <http://www.iges.org/grads/gadoc/gradfunccdiff.html> for how to
do that.
