[ncl-talk] Vertical wind shear calculation within 400 km radius of TC

Sat Jul 21 07:57:50 MDT 2018

[1] No idea where 'circle_lat and  circle_lon' are from. You will have to
find these sources.

[2] The 6.5.0 geo_location function is attached. Hopefully it runs under
6.3.0.
      Please read the documentation:

https://www.ncl.ucar.edu/Document/Functions/Contributed/geolocation_circle.shtml
      I suggest that you learn to use 'gc_inout'
        https://www.ncl.ucar.edu/Document/Functions/Built-in/gc_inout.shtml

[3] Upgrade to 6.5.0
     NCL 6.3.0 is ~3.5 years old
