Clouds Flashcards
What type of clouds will be formed if very stable moist is forced up slope?
Stratified clouds with little vertical development.
Stable Moisture forced Upslope:
Strat Clouds w/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.
Determines Structure/Type o/Clouds:
Stability Before lift
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.
4 Cloud Families:
- High
- Middle
- Low
- Extensive VD
A cirrostratus cloud is composed mostly of
Ice crystals.
Cirrostratus:
Ice Crystals 🧊
If standing lenticular clouds are seen over a mountainous are, a pilot should
be aware of severe mountain wave turbulence
Standing Lenticular Clouds ☁️ :
BE WARE—- SVR Mt Wave Turbulence
The presence of standing lenticular altocumulus clouds is a good indication of
very strong turbulence.
Standing Lens Alto:
Very Strong Turbulence
The presence of cumulus clouds often indicate
turbulence at and below the cloud level.
Cum ☁️ :
Turbulence A & B
Which family of clouds is least likely to contribute to structural icing on an aircraft?
High clouds.
Structural Ice:
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.
Unstable Air Mass Upslope:
- Extensive VD
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.
Cum Type Clouds ☁️ :
UMO
What type of cloud layer should you expect when flying into an unstable air mass?
Cumuliform.
Unstable :
- Cumuliform
The character of cumulonimbus cloud is
violent turbulence
CumBus:
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
Nimbostratus:
Layered 🌧️
