Earth:Significant tornado parameter
From HandWiki
The Significant Tornado Parameter, often abbreviated as STP or SigTor,[1] is a composite index used by the Storm Prediction Center to highlight areas across the United States where multiple ingredients for the development of tornadic supercells overlap,[2][3][4][5] and the capability of potential tornadic supercells producing "significant" tornadoes of EF2 intensity or higher.[6] Values greater than 1 indicate an increased potential of significant tornadoes.[7]
Equation
The equation used to calculate the parameter is as follows:[8]
STP = MLCAPE/1500 J/Kg^-1 x 2000-mlLCL/1000 m x ESRH/150 m/2 s^-2 x EBWD/20 m/s^-1 x 200+mlCIN/150 J/Kg^-1
