[ncl-talk] Skew T wind barbs

[Mary Haley]

Hi Kacie,

I don't know much about the skewT code, but the wind barbs are being drawn
with a call to "wmbarb". The wmbarb documentation:

http://www.ncl.ucar.edu/Document/Functions/Built-in/wmbarb.shtml

fails to mention the parameter "BLW", which increases line thickness (I'll
fix the documentation shortly).

Try adding this call:

wmsetp("BLW",3.0)    ;  Default is 1.0

I tried a value of 3.0 on a test code, and this was definitely thicker You
might need to go higher.

--Mary
