2. By the windT level profile in msl, find 1. By % growth formula @ end of flash time, we
the corresponding wind vel & deg C @ Hs+msl. find fictitious stack height Hs above ground.
These are the most sensitive parameters
for calculating final plume rise dh. Final 3. Cap Top Capt by 100% growth formula is height
height is Hf = Hs + dh + msl, still in msl. above ground.
4. Bring Hf down to height above ground by msl
to compare with Cap Top. The ratio (Hfmsl)/Cap Top
scales the Nuclear Cloud so Cap Bot by formula
is also scaled up/down, but now called new Cap Bot
or stem height StemH with msl correction added.
