A) Hadley cell
B) subtropical high
C) trade winds
D) polar front
Answer: B
6) In Eurasia, the land becomes cold in the winter and develops a seasonal high-pressure system from which surface flow is directed off the land. In the summer, in contrast, the opposite occurs: The landmasses are heated and develop a low-pressure cell, which permits air to flow onto the land. This "switch" in directions of airflow into or off of the continent gives rise to ______.
A) the monsoon
B) cyclones
C) the polar high
D) easterlies and westerlies
Answer: A

Answer:
11) Examine the map showing air pressure in millibars. Compare and contrast what sorts of weather situations would you expect at sites "B" and "D" on the map.
Answer: Site D is a center of low pressure, which means it's at the center of a midlatitude cyclone. Surrounding this site will be bands of clouds and wind that are flowing in toward Maine, spiraling in a counter-clockwise direction (because it is in the northern hemisphere). The close spacing of the isobars suggests high winds, too. All that air rising will likely be accompanied by precipitation. In contrast, site B, near New Orleans, is a center of high pressure. This means descending air, relatively clear skies, and no precipitation. It is likely surrounded by moderate winds spiraling outwards in a clockwise divergent pattern.
