170 Final Exam Study Outline
Final
Exams:
Sect. 1 (T Th 8:00 am class) Thursday, May 10, 8 -
10 am, AME 202
Sect. 2 (MWF 9:00 am class) Thursday, May 10, 10:30 am -

You can take the exam at either time. If you take the exam
with the other section (i.e. other than the section you're
enrolled in) please let me know ahead of time.
Reviews:
Wed., May 2 9:00 - 9:50 am Chem 111 (i.e. during the
normally scheduled class period on the last day of classes)
Wed., May 9 1:00-2:50 pm Chavez 405
1. Composition of the atmosphere: N2, O2,
H2O, Ar, and CO2. H2O and CO2
are main greenhouse gases. Importance of water vapor. Carbon
dioxide cycle (how is CO2 added to and removed from the
atmosphere). Atmospheric evolution (what important
atmospheric gas didn't come from volcanoes?)
2. Air
Pollution: Carbon
monoxide (CO) - incomplete combustion, early morning and
wintertime pollutant. Surface inversion layers. Sulfur dioxide (SO2)
- London type smog, acid rain. Tropospheric ozone (O3)
- key component of photochemical smog or Los Angeles type smog,
summertime afternoon pollutant.
Particulate matter. Scattering of light.
3.
Stratospheric ozone: importance, natural production and
destruction of ozone in the ozone layer, stratospheric ozone is
destroyed by CFCs
4.
Mass, weight, density, pressure: gravity pulls downward
on a mass producing weight. Pressure is a measure of the weight of
the air above. Mercury barometer. Typical sea level pressure
values and units. Air pressure and air density (mass/volume) both
decrease with increasing altitude.
Use the
Practice Quiz to test yourself on Topics 1 - 4
5.
Layers in the atmosphere: troposphere, tropopause, and stratosphere.
Temperature inversion (stable air layer).
6. Ideal gas law: How are P, N, V, T, and density
related? Temperature and density usually change in a way that
keeps pressure constant (Charles Law). Vertical forces on air
parcels, free convection. Archimedes law.
7. Station model notation & surface weather
maps: Average and usual range of sea level
pressure values, isobars and isotherms, winds around highs and
lows. Cyclones and anticyclones, convergence and divergence,
rising and sinking air, pressure gradient and wind speed.
8. Fronts:
symbols used for warm & cold fronts, crossectional structure
Use Quiz #1 to test yourself on
Topics 1 - 8
9. Energy and temperature: temperature is a measure of average kinetic
energy. Temperature scales. Delta T and Delta E relationship,
specific heat
10. Energy transport: conduction,
convection, latent heat (names of various phase changes, is energy
absorbed or given off), electromagnetic radiation
11.
Electromagnetic (EM) radiation: static electricity and
electric fields, wavelength, frequency, and energy. EM spectrum
- UV, visible, and IR light.
12. Rules:
governing the emission (kind and amount) of radiation.
13. Energy
balance (radiative equilibrium): on the earth with and
without an atmosphere. Selective absorption of radiation by
earth's atmosphere. Greenhouse gases and the greenhouse effect.
Effects of clouds on daytime and nighttime temperatures.
Use Quiz #2 to test yourself on Topics 9 - 13
14.
Humidity: saturation, humidity variables - mixing ratio,
saturation mixing ratio, relative humidity and dew point
temperature. Rain shadow effect, heat index. Cloud condensation
nuclei
15.
Identifying and naming clouds: ten cloud types, key
words.
16. Formation of
precipitation: collision coalescence process and
ice crystal process.
Types of precipitation: rain, drizzle,
snow, graupel, hail, sleet, freezing rain, virga.
Use Quiz #3 to test yourself on Topics 14 - 16
17.
Newton's 1st law of motion:
Forces
that
determine surface and upper level winds: PGF, Coriolis
force, friction. Rules for direction and strength.
18. Upper level winds: winds blow parallel to contours.
Northern and southern hemispheres, net inward force needed for any
kind of spinning motion..
Surface winds: blow across the
contour lines toward low pressure, northern and southern
hemisphere, convergence and divergence, rising and sinking
motions.
19.
Thunderstorms: air mass (3-stage life cycle) and severe
(tilted updraft). Gust front, shelf cloud, mammatus clouds, wind
shear, microbursts, anvil clouds.
20.
Tornadoes: general characteristics, life cycle, Fujita
scale. Mesocyclone and wall cloud, hook echo on radar.
21.
Lightning: thunderstorm charge structure, intracloud and
cloud-to-ground lightning (stepped leader, return stroke, multiple
strokes), lightning safety, distance to a lightning strike.
Use Quiz #4 to
test yourself on Topics 17 - 21
22. Hurricanes (typhoons and cyclones): Formation (where
and when). Eye, eye wall, spiral rain bands, low pressure &
converging winds at surface, high pressure & diverging winds
aloft. Stages of storm development. Storm surge and hurricane
damage, Saffir-Simpson scale.
Use the Fall 2003
Final Exam (see link below) to test yourself on all of this
material
Note:
The final exam usually consists of about 50+ multiple
choice, word choice, fill-in-the-blank style questions (like those
on this semester's quizzes). The final will include:
15 questions (at least) from this semester's 5 quizzes
(copies of all 4 quizzes + practice quiz are available via the
class web page)
10 questions (at least) from the Fall 2003 final exam
5 questions about hurricanes taken from this
list
