[ncl-talk] Issue with plotting wind vector barbs?

[Barry Lynn]

Hello:

I am not sure where these circles are, but you could try setting the wind
components to missing values:

e.g., u_wind = where(u_wind.lt.1.5,u_wind at _FillValue,u_wind)

Do the same for the v_component.

See if that removes the barbs where you don't want them.
