Pages 7 and 8

More complete discussion of the parameters and how they are calculated will come in future releases. For now, here is a listing of the parameter names in table 4 for reference.

You do not need to review the details of this page unless you have a particular question about a parameter.

Pages 7 and 8 contain storm-relative helicity, storm-relative wind vectors, mean wind vectors, and bulk shear and total shear.

STORM RELATIVE

• storm motion - first line in deg/kt (and m/s)
• SR Helicity (Storm-Relative Helicity) - sfc-2km, sfc-3km, lifted parcel layer to LFC
  • positive helicity
  • negative helicity
  • total helicity
• SR Winds (Storm-Relative Winds layer averaged vectors) - sfc-2km, 4-6km 9-11km (deg/kt and m/s)

MEAN WIND

• sfc-6km mean wind (deg/kt and m/s)
• LFC-EL mean wind (deg/kt and m/s)
• 850-200mb mean wind (deg/kt and m/s)

ENVIRONMENTAL SHEAR

• DELTA-V (bulk shear; kt and m/s) and TOT SHEAR (total length of hodograph; unknown units) for different LAYER
  • Low - 3 km - lowest 3km
  • Sfc-2km
  • Sfc-6km
  • Sfc-12km
