The SWEAT Index evaluates the potential for severe weather by examining both kinematic and thermodynamic information into one index. ... Unlike the K Index, the SWEAT index should be used to assess severe weather potential, not ordinary thunderstorm potential.  5, record 1, English, - severe%20weather%20threat%20index

SWEAT = 12D + 20(T - 49) + 2f₈ + f₅ + 125(S + 0.2), where D is the 850 hPa dew point in °C (if D is negative, it is set to zero); f₈ and f₅, the wind speed at 850 and 500 hPa in knots; S, the sine of the difference of the wind directions at 500 and 850 hPa; T, the total totals index in °C (if T is less than 49, the term 20(T - 49) is set to zero).  3, record 1, English, - severe%20weather%20threat%20index

Applications of the formula show that a SWEAT value of 300 represents a lower limit for the occurrence of severe thunderstorms and a value of 400 represents a lower limit for the occurrence of tornadoes.  3, record 1, English, - severe%20weather%20threat%20index
