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

[Carl Schreck]

Here is code that I used for something similar. It calculates the radius
around a storm (starting at line 85). Of course, you first have to read the
storm location. IBTrACS <https://www.ncdc.noaa.gov/ibtracs/> has great
resources for that.
