Weather Quiz 2

Question 1

Absolute altitude

Answer 1

AGL

Question 2

indicated altitude

Answer 2

height on altimeter

Question 3

true altitude

Answer 3

MSL

Question 4

Pressure altitude

Answer 4

altitude at 29.92

Question 5

density altitude

Answer 5

pressure converted for temperature differences

Question 6

If air is colder, how does true and indicated altitude compare

Answer 6

true altitude < indicated altitude

Question 7

why does steep terrain impact altimeter

Answer 7

dynamic pressure drops

Question 8

how to calculate density altitude

Answer 8

pressure + (118.8 * (ambient air temp - ISA temp))

Question 9

where is the strongest pressure gradient

Answer 9

vertically

Question 10

reading a find flag
triangle
full line
half line

Answer 10

50kts
10kts
5kts

Question 11

how does pressure gradient affect wind

Answer 11

wind flows high to low, tighter gradient = faster winds

Question 12

which force has the greatest affect in generating wind

Answer 12

pressure gradient

Question 13

which way does the wind deflect in the north

Answer 13

right

Question 14

what are the two forces that keep air to the earth but not in a flat layer

Answer 14

gravity
buoyancy

Question 15

air flows closer to isobars over land or water

Answer 15

water

Question 16

what is a jet stream

Answer 16

1-3 bands of fast air between equator and poles

strong narrow band of winds that encircles the earth at mid latittudes

Question 17

where is the top of jet streams

Answer 17

tropopause

Question 18

What part of weather kills the most people

Answer 18

air masses - extreme temperatures

Question 19

what happens when a cold continental front displaces maritime air

Answer 19

pressure decreases (lowest right at boundary layer)
temperature decreases
dew point decreases
winds rotate from SW to NW

Question 20

what conditions must exist for an air mass to form

Answer 20

stagnate air over an area
warm in tropical/subtropical areas
cold in polar areas
