Hodograph VAD

The following changes to the VAD display are proposed:

  • Add hodograph display and wind barb vs. height display for the 0.5, 1.5, 3.5 elevation angles
  • If data are available to sufficient depth, calculate 0-1 km and 0-3 km storm-relative helicity from GRIB-derived Bunkers storm velocity and from mean observed storm velocity of radar's cells
  • 0-6 km Bulk Shear
