Takeoffs and Landings Flashcards
atmosphere level from surface to 30,000 ft
1.1
troposphere
Atmosphere level between troposphere and stratosphere
1.1
tropopause
Lines of pressure
1.1
isobars
Steep pressure gradients (isobars and winds)
1.1
isobars close together and strong winds
Shallow pressure gradients (isobars and winds)
1.1
isobars far apart and light winds
Caused by the rotation of the earth
1.1
Coriolis Effect
The direction the air rotates in the Northern Hemisphere in high pressure
1.1
clockwise
The direction the air rotates in the Southern Hemisphere in high pressure
1.1
counter clockwise
Winds that flow parallel to isobars because of the coriolis effect.
1.1
Aloft
Upslope Winds
1.1
Warm winds that climb up mountains.
Downslope Winds
1.1
Cool winds that climb down mountains.
Water moving directly from a frozen to vapor w/o melting.
1.1
sublimation
Water moving directly from a vapor to frozen
1.1
desposition
Relative Humidity
1.1
the amount of moisture air can hold at a certain temp
A large difference between dew point and temp gives.
1.1
High-based clouds and good visibility
Calculating cloud height (AGL)
1.1
(dew point - temp)/2.5
Air that is much cooler above then below
1.1
Unstable
Air that has little to no temp decrease with altitude
1.1
stable air
unstable air, fluffy or bumpy
1.1
cumulus
stable air, layered
1.1
stratus
rain cloud
1.1
nimbo/nimbus
What are the 4 cloud families?
1.1

Clouds 16500 ft - 45000ft high, cirriform
1.1
high clouds
Clouds 6500 ft - 23000 ft high, alto
1.1
middle clouds
Clouds 0- 6500 ft high, strato
1.1
low clouds
