Clouds Flashcards
What type of clouds will be formed if very stable moist is forced up slope?
Stratified clouds with little vertical development.
What determines the structure or type of clouds which form as a result of air being forced to ascend?
The stability of the air before lifting occurs.
The suffix “nimbus”, used in naming clouds, means a
rain cloud.
What are the four families of clouds?
High, middle, low, and those with extensive vertical development.
A cirrostratus cloud is composed mostly of
Ice crystals.
If standing lenticular clouds are seen over a mountainous are, a pilot should
be aware of severe mountain wave turbulence
The presence of standing lenticular altocumulus clouds is a good indication of
very strong turbulence.
The presence of cumulus clouds often indicate
turbulence at and below the cloud level.
Which family of clouds is least likely to contribute to structural icing on an aircraft?
High clouds.
What type of clouds can be expected when an unstable air mass is forced to ascend a mountain slope?
Clouds with extensive vertical development.
Which of the following combinations of weather producing variables would likely result in cumuliform-type clouds, good visibility, rain showers, and possible clear-type icing in clouds?
Unstable, moist air, and orographic lifting.
What type of cloud layer should you expect when flying into an unstable air mass?
Cumuliform.
The character of cumulonimbus cloud is
violent turbulence
You are briefed that nimbostratus clouds prevail over most of your planned route. What type of weather conditions would you expect?
Layered clouds with rain
