GEOG. 2180 GEOSYSTEMS, ENVIRONMENT AND SOCIETY STUDY
GUIDE EXAM#2 WEATHER AND CLIMATE
The second hour exam covers these principal topics: circulation of the earth's atmosphere, weather
and climate, moisture, stability and clouds.
1. What is high pressure?
A circulating body of air that exerts relatively high pressure as
air sinks toward the surface Air flow diverges. Cooler air results
in higher air pressure.

What is a simple thermal circulation cell (Land and Sea Breeze)?
Develops due to differential heating when the earth's surface is
composed of two materials with different thermal characteristics
(ex: the thermal contrast btwn land and water)
The Land and Sea Breeze is the best example. It develops due to
differential heating when the earth’s surface is composed of two
materials with different thermal characteristics. The best
example is the thermal contrast between land and water .
What is the day pattern? During the day, cool air diverges over
the water and warm air converges over land. The cool air
diverges creates the sea breeze. The warmer place (land)
develops low pressure, warm land air converges, ascends, and
diverges aloft. The cooler place (water) develops high pressure,
