[ncl-talk] overlay

[Mary Haley]

Ehsan,

Please see example wrf_gsn_5.ncl and wrf_nogsn_5.ncl at

https://www.ncl.ucar.edu/Applications/wrfgsn.shtml

It shows you how to overlay several WRF plots on top of each other, using
WRF plotting functions, and gsn_csm plotting functions.

Adding shapefile outlines should be done to the map plot, and I believe
there's an example on the same page.
