Icing Example 2 (continued)

Hypothetical sounding for icing in stratus clouds

(If you haven't done so already, you can open the interactive skew-T with this sounding).

In what layer would you expect icing?
(Choose the best answer.)
a) 250-450 hPa
b) 450-550 hPa
c) 550-700 hPa
d) 700-800 hPa
e) 800-1000 hPa

That is incorrect.
Icing would be expected in clouds where the temperature falls between -3 and -16°C.
The correct answer is c).
Icing would be expected in the cloud layer from 550-700 hPa, where temperatures are between -3 and -13°C indicating existence of a supercooled environment.

What type(s) of icing would you expect to occur?
(Choose all that apply, then click Done.)
a) Clear
b) Rime
c) Mixed
The correct answer is b) Rime.
In the stable lifting associated with the observed temperatures in the stratus layer, expect rime icing to occur.
