1
What type of cloud is this and how does it form?
Stratus cloud;

forms in stable air near the surface due to cooling from below.
2
How do stratus clouds form?
forms in stable air near the surface due to cooling from below.
3
What type of cloud is this and how does it form?
Stratocumulus cloud;

form as stable air is lifted.

often form as a stratus layer breaks up or as cumulus clouds spread out
4
What type of cloud is this and what are the risks?
Altostratus

Produce minimal turbulence but can contain moderate icing
5
What type of cloud is this and where do they form?
Cirrus

Composed mostly of ice crystals and form above 30,000 feet
6
What type of cloud is this and what are the risks?
altocumulus

May produce light turbulence and icing
7
How do altocumulus clouds form?
They often form when altostratus clouds begin to break up.
8
What type of cloud is this and what are heights and the risks?
Cirrostratus

Can be thousands of feet thick;

Very low moisture content and no icing hazard.
9
What type of cloud is this and how do they form/what type of turbulence?
Cirrocumulus:

Forms as a result of shallow convective currents at high altitude

may produce light turbulence
