Flow Interaction with TopographyQuestions
Question 1
Which of the following factors increase the likelihood that wind will be blocked by topography? (Choose all that apply.)
The correct answers are a) "greater stability" and b) "increased height of terrain."
A stable atmosphere resists vertical motions. As boundary layer stability increases, it becomes more likely that wind will be blocked by terrain. Increased terrain height and decreased wind speed also increase the chance that terrain will block the wind.
Question 2
[True/False] The boundary layer in the Arctic is typically very stable.
The correct answer is True.
The boundary layer in the Arctic over the ocean, snow, or ice is characterized by a surface-based inversion.
Question 3
Use the selection boxes to choose the answers that best complete the statements.
The correct answer is that the Aleutian Islands frequently experience gap winds, while the east coast of Greenland frequently experiences a barrier jet.
