Room 213 MLC (AM) or Chemistry Room 400 (PM)
What does it cover? 1)
Ackerman and Knox, chapters 11,12,13
on: thunderstorms, tornadoes, lightning and thunder, hail, weather safety,
small-scale winds (some), and weather forecasting
How long will it be?
Probably the shortest test of the semester—use extra time wisely!!
How much math is on it?
Same or less than previous tests!
Something with the Lifted Index
that ties in with Test #2 material, or lightning vs. thunder, or wind speeds in a multiple-vortex
Expect maps that you use to ID locations, e.g. where in the U.S. thunderstorms,
tornadoes and hail are most common, etc.
Do I need a calculator?
, just to be safe.
What is the test format?
multiple-choice or T/F questions
DO NOT SKIP ANY QUESTIONS!!!!
What do I need to bring?
number 2 pencil (not provided)
to use on CompuTest forms
CANNOT USE TEXT; CANNOT
USE NOTES; CANNOT USE FORMULA SHEET.
Any formulas you need, I’ll give to you.
Will all the tests be like this one?
Not necessarily, so carefully read each test study sheet!
What should I study?
See below for study questions!
GEOG 1112 Possible Test #4
italics means map-related,
* = math-related)
The Earth’s electromagnetic energy peaks in the (light/heat/microwave) part of the electromagnetic spectrum.
What happens to the surface temperature and dew point when rain falls into unsaturated near-surface air?
Explain why wind blowing across the isobars toward lower pressure leads to bad weather.
What direction do South American polar jet streams blow toward?
North American polar jet streams?
How does ENSO affect hurricane seasons?
Which jet stream seems to be related to this, and what does it do?
Name two general locations where air masses are formed.
Why there and not in the mid-latitudes?
A cold front is about to move past your location.
What’s the forecast (temp, dew point, winds, clouds, precip)?
Draw an extratropical frontal cyclone.
Label each front.
Label typical air masses behind the cold front,
between the warm and cold fronts south of the low, and ahead of the warm front.
Which air mass will probably have the highest dew point: cP, mP, or mT?
10. Because cold and warm fronts are regions of strong temperature gradients, what meteorological phenomenon
usually exists high above them in the upper troposphere?
What is the name for the
that explains this?
11. T/F: Doppler radar can ‘see’ hurricanes thousands of miles out at sea.
12. If you have warm moist air present and instability aloft, what other ingredient do you need to cause a
What are four ways of getting this ingredient?
13. What are the three types of thunderstorms?
