Alain,

Your image shows missing "isotachs" of mag(wnd) in specific areas. You had 
stated that
you were able to plot vectors at this same level/time/parameter- though the
plot didn't show the vectors. Your plot parameters had shown that this was 
GLEVEL=200
though your script.txt doen't show calculation of a layer that high. Most 
likely,
the moisture grid had 0 (or negative/missing in that area). Its possible that 
you were 
looking at vector components for a different level and they were in fact 
missing at 200 mb.


I suggest that in gddiag, you write the output to grids other than "UREL" and 
"VREL" 
since those names and the use of those to compose WND may get confused. Rather, 
use
GRDNAM to something like utrans and vtrans, and then plot 
mag(vecr(utrans,vtrans)).
