The index is formulated as follows:
STP = (sbCAPE/1500 J kg-1) * ((2000-sbLCL)/1000 m) * (SRH1/150 m2 s-2) * (6BWD/20 m s-1)
The sbLCL term is set to 1.0 when sbLCL < 1000 m, and set to 0.0 when sbLCL > 2000 m; the 6BWD term is capped at a value of 1.5 for 6BWD > 30 m s-1, and set to 0.0 when 6BWD < 12.5 m s-1.
A majority of significant tornadoes (F2 or greater damage) have been associated with STP values greater than 1, while most non-tornadic supercells have been associated with values less than 1 in a large sample of RAP analysis proximity soundings.

Gewoon heet en nat volgende week, zoals Frank zei:b.
Misschien maakt dat wat duidelijk
