Graphics: NCL – Example

A example script to calculate updraft helicity: wrf_updraft_helicity.ncl

1. In this example we calculate updraft helicity
2. Note in the wrf_user_getvar function, "updraft_helicity" will default to helicity between 2-5km.
3. To specify custom levels, for instance 2.5 to 6km, use: (/"updraft_helicity","2500","6000"/)
