29. Fog & Atmospheric Pressure Flashcards
Layered clouds are called:
Stratus.
What conditions should you expect when flying in and around stratus clouds?
A smooth flight with fair to poor visibility.
Clouds with extensive vertical development are called:
Cumulus
When flying in or around cumulus clouds, you might expect:
A bumpy flight with good visibility.
Earth’s atmosphere is divided into three parts. Proceeding from the Earth’s surface in order they are:
- Troposphere
- Tropopause
- Stratosphere.
Low level inversions cause:
Smoke and dust to be trapped close to the surface.
Cold air generally contains:
Less water vapor than warm air.
To condense, water vapor needs:
Something to latch on to such as a dust particle.
Which type of fog is most likely to form inland?
Radiation fog, sometimes called ground fog.
One of the key indicators that fog might form is:
A small temperature/dew point spread.
What is the temperature and atmospheric pressure at sea level on a standard day?
59° F. and 29.92” Hg of mercury.
Cold temperatures make the atmosphere contract lowering the pressure level. Remember this sentence:
High temperatures to low, look out below.
