Pages 9 and 10

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 5 for reference.

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

Pages 9 and 10 contain more severe weather parameters:

CONVECTIVE INITIATION

• CINH - convective inhibition (J/kg) for the latest lifted parcel to reach the LFC
• Cap - temperature of the cap (C) and associated pressure (mb) for latest lifted parcel
• K-Index
• Mean RH - mean relative humidity (%)
• Top of Moist Lyr - the estimated top of the surface moist layer, pressure (mb), hgt ASL (ft)
• LFC Height - level of free convection for latest lifted parcel, pressure (mb), and ht (ft)

STORM TYPE

• CAPE - convective available potential energy for the latest lifted parcel (J/kg)
• EHI - Energy Helicity Index
• BRN - Bulk Richardson Number
• Eff SREH - effective storm-relative environmental helicity (m2/s2)
• 3km shear - sfc-3km bulk shear (m/s)
• BRN Shear - shear in the denominator of the BRN (m2/s2)

PRECIPITATION TYPE

• meliting level - melting level ht (kt) and pressure (mb)

HEAVY RAINFALL

• Rogash QPF - unknown

SEVERE POTENTIAL

• HAIL POTENTIAL
  • CAPE (J/kg)
  • WBZ level - Wet Bulb Zero
  • Mid Lvl RH - some form of mid level relative humidity (%)
  • FGZ level - freezing level
  • EL Storm-Relative Wind Speed (kt)
  • CH1 - unknown
  • CH2 - unknown
  • Avg BL Wetbulb Temp - average boundary layer wetbulb temperature (C)
• TORNADO POTENTIAL

• Storm-relative wind speed layers
  • Low levels (sfc-LFC; kt)
  • Mid levels (LFC to 4km above LFC; kt)
  • High levels (4km below EL to EL; kt)...note this is labeled incorrectly as Low SRW (EL-4km - EL) when it should be high
