What is the wet-bulb zero level in the sounding?
hPa
The correct answer is 750 hPa.
Do we need to apply the second Fawbush-Miller Nomogram to modify the predicted hail size?
Yes
No
The correct answer is No.
As you may recall from page 6 of this section,
you apply the second nomogram if
the wet-bulb zero height is above 10,500 feet (~670 hPa).
Since the wet-bulb zero level is lower than the 670 hPa level,
no modification of hail size is necessary.
