1. What is the primary driver of weather? Uneven heating of
the surface of the
earth
2. In a standard atmosphere the environmental lapse 2º per 1,000ft
rate is
3. The dry adiabatic lapse rate is 3º per 1,000ft
4. The wet adiabatic lapse rate is 1.5º per 1,000ft
5. A stable atmosphere occurs when the environmental Shallow or nega-
lapse rate is tive
6. An unstable atmosphere occurs when the environ- Steeper than both
mental lapse rate is the wet and dry
adiabatic lapse
rates
7. A potentially unstable atmosphere occurs when the Somewhere be-
environmental lapse rate is tween the dry
an wet adiabatic
lapse rates
8. ISA 15º and pres-
sure at sea lev-
el of 29.92"
(1013.2hpa)
9. The average height of the tropopause is 36,000ft
10. For every 1,000ft climbed, mercury drops approxi- 1"
mately
11. Relative humidity The amount of wa-
ter in the air rel-
ative to the maxi-
mum it can hold at
given temperature
and pressure

12. Dewpoint The temperature
at which conden-
sation begins
13. Is humid air or dry air more dense? Dry air
14. Convection Vertical move-
ment of air
15. Advection Horizontal move-
ment of air
16. Deposition When gas
changes *directly*
to a solid
17. Isobars Lines of con-
stant/equal pres-
sure
18. Isotachs Lines of con-
stant/equal wind
velocity
19. Contour lines Lines where the
altitude at which a
specified pressure
occurs is constant
20. Cloudy/rainy weather is associated with Low pressure sys-
tem (ascending
air)
21. Which way does air circulate in a low pressure sys- Counter-clock-
tem? wise
22. Warm/sunny weather is associated with High pressure
system (descend-
ing air)
