Chapter #11 Solutions - Essentials of Meteorology - C Donald Ahrens - 6th Edition

1qr. What is a tropical (easterly) wave? How do these waves generally move in the Northern Hemisphere? Are showers found on the eastern or western side of the wave? Get solution

1qt. A hurricane just off the coast of northern Florida is moving northeastward, parallel to the eastern sea board. Suppose that you live in North Carolina along the coast. (a) How will the surface winds in your area change direction as the hurricane’s center passes due east of you? Illustrate your answer by making a sketch of the hurricane’s movement and the wind flow around it. (b) If the hurricane passes east of you, the strongest winds would most likely be blowing from which direction? Explain your answer. (Assume that the storm does not weaken as it moves northeastward.) (c) The lowest sea-level pressure would most likely occur with which wind direction? Explain. Get solution

2qr. Why are streamlines, rather than isobars, used on surface weather maps in the tropics? Get solution

2qt. Get solution

3qr. What is the name given to a hurricane-like storm that forms over the western North Pacific Ocean? Get solution

3qt. Give several reasons how a hurricane that once began to weaken can strengthen again. Get solution

4qr. Describe the horizontal and vertical structure of a hurricane. Get solution

4qt. Why are North Atlantic hurricanes more apt to form in October than in May? Get solution

5qr. Why are skies often clear or partly cloudy in a hurricane’s eye? Get solution

5qt. Explain why the ocean surface water temperature is usually cooler after the passage of a hurricane. (Hint: The answer is not because the hurricane extracts heat from the water.) Get solution

6qr. What conditions at the surface and aloft are necessary for hurricane development? Get solution

6qt. Suppose this year five tropical storms develop into full-fledged hurricanes over the North Atlantic Ocean. Would the name of the third hurricane begin with the letter C? Explain. Get solution

7qr. List three “triggers” that help in the initial stage of hurricane development. Get solution

7qt. You are in Darwin, Australia (on the north shore), and a hurricane approaches from the north. Where would the highest storm surge be, to the east or west? Explain. Get solution

8qr. (a) Hurricanes are sometimes described as a heat en gine. What is the “fuel” that drives the hurricane? (b) What determines the maximum strength (the highest winds) that the storm can achieve? Get solution

9qr. Would it be possible for a hurricane to form over land? Explain. Get solution

10qr. If a hurricane is moving westward at 10 knots, will the strongest winds be on its northern or southern side? Explain. If the same hurricane turns northward, will the strongest winds be on its eastern or western side? Get solution

11qr. What factors tend to weaken hurricanes? Get solution

12qr. Distinguish among a tropical depression, a tropical storm, and a hurricane. Get solution

13qr. In what ways is a hurricane different from a mid-latitude cyclone? In what ways are these two systems similar? Get solution

14qr. Why do most hurricanes move westward over tropical waters? Get solution

15qr. If the high winds of a hurricane are not responsible for inflicting the most damage, what is? Get solution

16qr. Most hurricane-related deaths are due to what? Get solution

17qr. Explain how a storm surge forms. How does it inflict damage in hurricane-prone areas? Get solution

18qr. Hurricanes are given names when the storm is in what stage of development? Get solution

19qr. When Hurricane Andrew moved over south Florida during August, 1992, what was it that caused the relatively small areas of extreme damage? Get solution

20qr. As Hurricane Katrina moved toward the Louisiana coast, it underwent eyewall replacement. What actually happened to the eyewall during this process? Get solution

21qr. How do meteorologists forecast the intensity and paths of hurricanes? Get solution

22qr. How does a hurricane watch differ from a hurricane warning? Get solution

23qr. Why have hurricanes been seeded with silver iodide? Get solution

24qr. Give two reasons why hurricanes are more likely to strike New Jersey than Oregon. Get solution
