[gradsusr] How to calculate shear between two levels

[Jeff Duda]

The following should get it done:

'open (uwnd file)'
'open (vwnd file)'

'set lev 850'

'define ushear = uwnd(lev=200) - uwnd'
'define vshear = vwnd.2(lev=200) - vwnd.2'

'set gxout vector (or barb)'
'd skip(ushear,2 [or whatever value you'd like]);vshear'
