12. The United States does not experience a monsoon.
false 12

13. Seasonal changes in pressure are greater over continents than over the oceans.
true 13

14. Jet stream winds are completely distinct from the mid-latitude westerlies.
false 14

15. For much of South and Southeast Asia, winter is a period characterized by relatively dry conditions.
true 15

16. The wind called the "norther" in Texas is really not a local wind but rather is a synoptic scale (macroscale) phenomenon.
true 16

17. The areas of abundant rainfall on the earth tend to be
near the equator and in mid-latitudes. 17

18. Concerning rainfall patterns, areas of persistent high pressure tend to cause.
desert regions. 18

19. Why do westerly winds prevail at upper altitudes?
rotation of the earth and equator to pole temperature contrast 19

20. Surface high pressure zones are usually associated with
clear or nearly clear weather. 20

21. Jet streams are associated with fronts because of the
large temperature gradient. 21

22. Microscale winds generally last for:
a few seconds. 22

23. Most of the United States is situated in which zone of prevailing winds?
westerlies 23

24. The prevailing winds that blow from the horse latitudes toward the doldrums are called:
trade winds. 24

25. When are upper air winds fastest?
In the winter 25

26. Summertime wildfires in California are fanned by:
the Santa Ana winds. 26

27. Jet streams occur where?
occur at 25,000 to 40,000 feet in middle latitudes. 27

28. Winds are usually named for.
the direction or place from which they are blowing. 28

29. The prevailing winds that tend to influence cities such as Chicago and New York City are
westerlies. 29

30. The definition of the word 'monsoon' means
seasonal wind shift. 30

31. circulation patterns in the atmosphere.
The amount of precipitation received at a given location is primarily controlled by
circulation patterns in the atmosphere. 31
