Re: Surface Divergence

Chris,

Try setting SCALE=999 to let GEMPAK scale the data rather than
trying to plot values on the order of E-10 (or set SCALE to
an appropriate order of magnitude once you have a feeling of the typical
data range).

With CINT = blank as you have, the package will try to create around 16
contour
levels, but in a loop of times, consistent scaling and contour intervals
is best.

I'm trying to display surface divergence and convergence (technically speaking it is at 10m) from the CMC Regional model. Can someone look at my restore file and tell me what I am doing wrong? All I get when it plots is a lot contours with a value of -2.9E-10. What I am looking for is a contour plot highlighting areas of maximum convergence and divergence at the surface.

Chris
