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
high, middle, low and vertical development
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
The decrease of air temp w altitude.
1.2
lapse rate
Air that has a larger than normal lapse rate
1.2
unstable
A huge body of air with similar temp and moisture content.
1.2
air mass
The 4 types of air masses.
1.2
continental, maritime, polar, tropical
A dry air mass
1.2
continental
A moist air mass
1.2
maritime
The boundary between 2 air masses with different temps and wind direction
1.2
front
What is a cold front? How does it look on a weather chart?
1.2
cold air displaces warm air
icicles/triangular = wind speed
What is a warm front? How does it look on a weather chart?
1.2
warm air displaces cold air
half suns/half circles = 1/2 wind speed
What is a stationary front? How does it look on a weather chart?
1.2
moves less than 5 kts
opposing icicles and half suns
Fast moving cold front lifts warm air completely off the ground and overtakes cool air in front of a warm air mass
1.2
cold front occlusion
Fast moving cold front lifts warm air completely off the ground and the cold air mass ahead is the coldest of the 3 air masses.
1.2
warm front occlusion
The 5 types of fog
radiation, advection, upslope, precipitation-induced, and steam
shallow fog, develops in clear skies, when air near the ground cools with high humidity and low/no wind
radiation
fog that requires wind, develops rapidly, warmer air moves over a colder surface and its temp drops
advection
fog that requires wind, develops due to air rising, expanding and cooling to dew point, occurs when stable air is forced to rise up a mountain slope
upslope
fog occurs when relatively warm rain falls through cool air
precipitation
fog forms over bodies of water, requires wind, and occurs when cold air from land flows over relatively warmer water
steam
A cumulus cloud producing rain
cumulonimbus
requires a lifting force, unstable, moist air
thunderstorm
What are the 3 stages of a thunderstorm?
cumulus, mature, dissipating
What are the 2 types of thunderstorms?
air mass and frontal
Stage of a thunderstorm with vertical cloud build-up, continuous strong updrafts
cumulus
Stage of a thunderstorm with up and down drafts, precipitation, gusty surface winds, temp drop and pressure increase
mature
Wind shear
wind that changes rapidly in direction or velocity
