GEOG. 2180GEOSYSTEMS, ENVIRONMENT AND SOCIETYSTUDY GUIDE EXAM#2WEATHER AND CLIMATEThe 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 resultsin higher air pressure.
What is a simple thermal circulation cell (Land and Sea Breeze)?Develops due to differential heating when the earth's surface iscomposed 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 todifferential 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,
