Dr. Sanders
By the end of today's class, you should be able to do the following:
WEATHER, CONTINUED
w
Review, plus one new concept:
Explain how temperature
and moisture content of an air mass affect its density.
w
Review:
Describe continental polar (cP),
maritime tropical (mT), continental Arctic, (cA),
and other air masses that affect the continental United States. (See
http://okfirst.mesonet.org/train/meteorology/AirMasses.html
and
http://www.qc.ec.gc.ca/meteo/Documentation/Masse_e.html .)
w
Complete the data collection and
analysis of the "Weather
Tracking Day 1" worksheet, and compare your CONCLUSIONS with the rest
of the class.
w
List the steps that lead to the formation of a cloud.
w
Explain the terms condensation and condensation nuclei
as they relate to cloud formation.
w
Describe the characteristics of cirrus, cumulus,
and stratus clouds.
w
Tell what
cumulonimbus and nimbostratus clouds have that ordinary
cumulus and stratus clouds don't.
w
Explain the processes that lead to orographic,
convective, and frontal precipitation, and sketch a
diagram illustrating each one.
w
Make a sketch of a warm front and
use it to explain why precipitation is associated with these fronts.
w
Make a sketch of a cold front and
use it to explain why precipitation is associated with these fronts.
w
Explain the meaning of air
pressure / barometric pressure.
w
Move on to
"Weather Tracking Day 2",
using the map linked here.
Today, the focus is on high and low pressure systems and how they relate to
fronts and precipitation.
Here's a cool weather site for anyone,
but especially for you pre-service teachers!
