---------------------------------------------------------------------------------------------------
Update Time = UTC Time of BLIPSPOT calculation
FCST PERIOD = Hours from model initialization time
Temp@2m = Temperature at 2m AGL [F]
Sfc.Heating = Surface Heating of atmosphere [W/m^2]
BL Depth = Depth of the Boundary (Mixing) Layer [ft]
Hcrit = Height of Critical Updraft Strength [ftMSL]
BL Top = Height of Boundary Layer Top (TI=0 height) [ftMSL]
Hgt.Variab = Thermal Height Variability (difference between TI=+4{F} & TI=0 Heights) [ft]
W* = Thermal Updraft Velocity (subtract glider sink rate to get vario) [fpm]
B/S = Buoyancy/Shear Ratio (thermals may be unworkable if 5 or less)
BL Wind = Wind Speed averaged through BL [kt]
Direction = Wind Direction averaged through BL [degTrue]
Max.Converg = Max. Vertical Velocity created by BL Convergence [x10^-2 kt]
(note: BLIPMAPs provide better evaluation since convergence lines are usually mobile
CLOUDpotent = Expect clouds at or above sfcLCL if positive (difference between H(TI=0) & sfcLCL) [ft]
sfcLCL = Base of Lowest Clouds, if CLOUDpotent>0 (LCL = Lifting Condensation Level based upon sfc. humidity) [ftMSL]
ODpotential = Expect extensive clouds at blCL if positive (difference between H(TI=0) & blCL) [ft]
bLCL = Base of Extensive Clouds, if ODpotential>0 (bl CL = Condensation Level based upon BL humidity) [ftMSL]
maxRH = Maximum Relative Humidity in BL [%]
CAPE = Convective Available Potential Energy [J/kg]
Temp@2m = Temperature at 2m AGL [F]
DewPt@2m = Dew Point Temp. at 2m AGL [F]
Temp@Bot = Temperature at 16m AGL (bottom of grid) [F] (intended for DrJack's use)
DewPt@Bot = Dew Point Temp. at 16m AGL (bottom of grid) [F] (intended for DrJack's use)
Sfc.Heating = Surface Heating of atmosphere [W/m^2]
BL Depth = Depth of the Boundary (Mixing) Layer [ft]
EXPERIMENT = Mystery variable for test purposes (intended for DrJack's use)
* = Indicates BL Top (TI=0 Height) on profiles
Note: printed heights are for 21Z - heights for other times differ slightly
Results neglect thermals created by small-scale features not resolved by the smoothed model topography
