1qr. Describe the various scales of motion and give an example of each. Get solution

1qt. Suppose you are fishing in a mountain stream during the early morning. Is the wind more likely to be blowing upstream or downstream? Explain why. Get solution

2qr. What is wind shear and how does it relate to clear air turbulence? Get solution

2qt. Why, in Antarctica, are winds on the high plateaus usually lighter than winds in steep, coastal valleys? Get solution

3qr. Using a diagram, explain how a thermal circulation develops. Get solution

3qt. What atmospheric conditions must change so that the westerly flowing polar front jet stream reverses direction and becomes an easterly flowing jet stream? Get solution

4qr. Why does a sea breeze at the surface blow from sea to land and a land breeze from land to sea? Get solution

4qt. After a winter snowstorm, Cheyenne, Wyoming, reports a total snow accumulation of 48 cm (19 in.), while the maximum depth in the surrounding countryside is only 28 cm (11 in.). If the storm’s intensity and duration were practically the same for a radius of 50 km around Cheyenne, explain why Cheyenne received so much more snow. Get solution

5qr. (a) Briefly explain how the monsoon wind system develops over eastern and southern Asia. (b) Why in India is the summer monsoon wet and the winter monsoon dry? Get solution

5qt. The prevailing winds in southern Florida are northeasterly. Knowing this, would you expect the strongest sea breezes to be along the east or west coast of southern Florida? What about the strongest land breezes? Get solution

6qr. Which wind will produce clouds: a valley breeze or a mountain breeze? Why? Get solution

6qt. Explain why icebergs tend to move at right angles to the direction of the wind. Get solution

7qr. What are katabatic winds? How do they form? Get solution

7qt. Give two reasons why pilots would prefer to fly in the core of a jet stream rather than just above or below it. Get solution

8qr. Explain why chinook winds are warm and dry. Get solution

8qt. Why do the major ocean currents in the North Indian Ocean reverse direction between summer and winter? Get solution

9qr. (a) What is the primary source of warmth for a Santa Ana wind? (b) What atmospheric conditions contribute to the development of a strong Santa Ana wind? Get solution

9qt. Explain why the surface water temperature along the northern California coast is warmer in winter than it is in summer. Get solution

10qr. Describe how dust devils usually form. Get solution

10qt. The Coriolis force deflects moving water to the right of its intended path in the Northern Hemisphere and to the left of its intended path in the Southern Hemisphere. Why, then, does upwelling tend to occur along the western margin of continents in both hemispheres? Get solution

11qr. Draw a large circle. Now, place the major surface semi permanent pressure systems and the wind belts of the world at their appropriate latitudes. Get solution

12qr. According to Fig. 7.25 (p. 203), most of the United States is located in what wind belt? Reference: Figure 7.25: ... Get solution

13qr. Explain how and why the average surface pressure features shift from summer to winter. Get solution

14qr. Explain why summers along the West Coast of the United States tend to be dry, whereas along the East Coast summers tend to be wet. Get solution

15qr. How does the polar front influence the development of the polar front jet stream? Get solution

16qr. Why is the polar jet stream more strongly developed in winter? Get solution

17qr. Explain the relationship between the general circulation of air and the circulation of surface ocean currents. Get solution

18qr. . Describe how the winds along the west coast of North America produce upwelling. Get solution

19qr. (a) What is a major El Niño event? (b) What happens to the surface pressure at opposite ends of the Pacific Ocean during the Southern Oscillation? (c) Describe how an ENSO event may influence the weather in different parts of the world. Get solution

20qr. What are the conditions over the tropical eastern and central Pacific Ocean during the phenomenon known as La Niña? Get solution

21qr. How does the positive (warm) phase of the Northern Atlantic Oscillation differ from the negative (cold) phase? Get solution

22qr. During the negative (cold) phase of the Arctic Oscillation when Greenland is experiencing mild winters, what type of winters (cold or mild) is Northern Europe usually experiencing? Get solution

23qr. Describe the ocean surface temperatures associated with the Pacific Decadal Oscillation. Get solution
