Weather And Micrometeorology Flashcards
Standard air temp is
15degreesC, 59degreesF
Standard air pressure
29.92 inHg
True altitude is
Mean sea level or MSL
Low level temperature inversion is when
There’s an increase in temp as altitude increases
BKN =
Broken
OVC =
Overcast
BR =
Mist
SH =
Showers
RA =
Rain
Advection fog =
Air mass moves INland from coast
AD= in
Wind sheer can be expected
In areas of low level temp inversion
What conditions are necessary for a thunder storm to form?
High Humidity, Lifting Force, and UNSTABLE CONDITIONS
Mature stage of a thunderstorm begins with
Precipitation
If you see lenticular clouds expect
Turbulence
What are the characteristics of a moist, unstable air mass?
Turbulence and showery precipitation
Ceiling conditions (cloud base) can be calculated from
The temp and dew point
For aviation purposes ceiling is defined as the height above the earths surface of the
Lowest broken or overcast layer or vertical visibility into an obstruction
What effect does Low density altitude have on propellers
The propeller efficiency will be increased
Z to PST =
- 8 hours
Z to CST =
-6 hours
Z to EST =
- 5 hours
