The correct answer is 464.
SWEAT = 12(850T
d) + 20(TT-49) + 2(V850) + (V500) + 125(sin(dd500-dd850) + 0.2)
= 12(13) + 20(51-49) + 2(40) + (65) + 125(sin(240-190) + 0.2)
= 464.2
Note the SWEAT index value also appears in the parameters listing
to the right of the plotted sounding on the Interactive Skew-T.
Incorrect. Recall that a SWEAT index greater than 300 indicates a possibility of
severe convection, while a value greater than 400 indicates a high likelihood of severe convection
with possible tornadoes.
