Icing by Cloud Type

Question 1

Type of icing that is encountered in Cirrus Cloud?

Answer 1

No icing as the cloud consists of ice crystals

Question 2

Type of icing that is encountered in Cirrostratus Cloud?

Answer 2

No icing as the cloud consists of ice crystals

Question 3

Type of icing that is encountered in Cirrocumulus Cloud?

Answer 3

Rare as the cloud consists mainly of ice crystals

Question 4

Type of icing that is encountered with altostratus cloud?

Answer 4

Light rime ice

Potentially clear ice in thick altostratus

Question 5

Type of icing that is encountered with altocumulus cloud?

Answer 5

If the cloud is thin light rime may occur
There is usually always turbulence associated with altocumulus cloud and this enables the cloud to support supercooled water drops

Question 6

Type of icing that is encountered with stratus cloud?

Answer 6

No ice will form because temperature will usually be above 0
If the temperature was below zero, light rime may form
Lack of turbulence and hence lack of large water droplets means clear ice wont form

Question 7

Type of icing that is encountered with Nimbostratus cloud?

Answer 7

Clear ice very real risk up to 5,000ft above freezing level, after this level light rime ricing will occur

Question 8

Type of icing that is encountered with Stratocumulus cloud?

Answer 8

Rime ice will occur provided temperature is below 0 which is rarely the case in Australia

Question 9

Type of icing that is encountered with Cumulus cloud?

Answer 9

Large cumulus can produce clear ice up to about 5,000ft above freezing level, above which rime ice will occur.
This however isn’t common in small cumulus cloud because it is usually always above freezing level

Question 10

Type of icing that is encountered with a Cumulonimbus cloud?

Answer 10

Clear ice from 0 to -15 degrees

Rime ice will occur above this up until ice crystal presence
