Answer to Question 1ANS: D
Although the average flows of surface winds follow a predicted six-cell model, there are east-west
variations that can occur. Information can be found in the section Atmospheric Circulation Generates
Large-Scale Surface Wind Patterns
Answer to Question 2ANS: C
Easterlies, also known as trade winds, are the most constant surface winds found between the zones of
descending and ascending air masses. Information can be found in the section Atmospheric Circulation
Generates Large-Scale Surface Wind Patterns.
