Hi ncl-talk,
I made all the changes but I'm still unable to plot a zoomed in an overlay
of both winds, temperature, and geopotential height.
I'm not getting any errors though but it just will not plot or plot right.
I have attached to figure.
Whatever help you can offer me will be greatly appreciated.
Thanks!!!
