[ncl-talk] plot masked vectors

[Michele Petrini - CITG]

Dear helpdesk,

I am trying to plot velocity vectors over a contour (+other stuff, see attached pdf).

I have a question, is there a way to mask out the small vectors and leave only velocity vectors exceeding some threshold (let’s say 100 m/yr)?

If I try to mask the u/v variables, I get an error.

Looking on the internet, I see that there is someone suggesting to overlay two vector contours, but the procedure seems to be a little bit complicated, and I wonder if there exists a simpler way,..

thanks!
Michele
