[ncl-talk] difference between using res at tfDoNDCOverlay and @lat2d @lon2d when overlaying wind vectors

[xiaoming Hu]

Hello


 If I use res at tfDoNDCOverlay  I got the figure of

[cid:c0f4f858-bf59-4f1a-9241-88c9b68f655f]

But If I use @lat2d @lon2d without res at tfDoNDCOverlay  I got

[cid:5108a2f1-0cbf-4ea5-9260-f9aabdf866a4]

The wind vectors near the right edge in the left panel do not follow the pressure lines now.


Any comments on overlaying wind vectors using res at tfDoNDCOverlay    or using @lat2d @lon2d without res at tfDoNDCOverlay ?

I attached my ncl script

Thanks

Xiaoming
