Chapter #14 Solutions - Essentials of Meteorology - C Donald Ahrens - 6th Edition

1qr. What are some of the main sources of air pollution? Get solution

1qt. Would you expect a fumigation-type smoke plume on a warm, sunny afternoon? Explain. Get solution

2qr. How do primary air pollutants differ from secondary air pollutants? Get solution

2qt. Give a few reasons why, in industrial areas, nighttime pollution levels might be higher than daytime levels. Get solution

3qr. List a few of the substances that fall under the category of particulate matter. Get solution

3qt. Explain this apparent paradox: High levels of tropospheric (ground-level) ozone are “bad” and we try to reduce them, whereas high levels of stratospheric ozone are “good” and we try to maintain them. Get solution

4qr. How does PM-10 particulate matter differ from that called PM-2.5? Which poses the greatest risk to human health? Get solution

4qt. A large industrial smokestack located within an urban area emits vast quantities of sulfur dioxide and nitrogen dioxide. Following criticism from local residents that emissions from the stack are contributing to poor air quality in the area, the management raises the height of the stack from 10 m (33 ft) to 100 m (330 ft). Will this increase in stack height change any of the existing air quality problems? Will it create any new problems? Explain. Get solution

5qr. How is particulate matter removed from the atmosphere? Get solution

5qt. If the sulfuric acid and nitric acid in rainwater are capable of adversely affecting soil, trees, and fish, why doesn’t this same acid adversely affect people when they walk in the rain? Get solution

6qr. Describe the primary sources and some of the health problems associated with each of the following pollutants: (a) carbon monoxide (CO) (b) sulfur dioxide (SO2) (c) volatile organic compounds (VOCs) (d) nitrogen oxides Get solution

6qt. Which do you feel is likely to be more acidic: acid rain or acid fog? Explain your reasoning. Get solution

7qr. How does London-type smog differ from Los Angeles-type smog? Get solution

7qt. Keep a log of the daily AQI readings in your area and note the pollutants listed in the index. Also, keep a record of the daily weather conditions, such as cloud cover, high temperature for the day, average wind direction and speed, etc. See if there is any relationship between these weather conditions and high AQI readings for certain pollutants. Get solution

8qr. What is photochemical smog? How does it form? What is the main component of photochemical smog? Get solution

9qr. Why is photochemical smog more prevalent during the summer and early fall than during the middle of winter? Get solution

10qr. Why is stratospheric ozone beneficial to life on earth, whereas tropospheric (ground-level) ozone is not? Get solution

11qr. If most of the ozone in the stratosphere were destroyed, what possible effects might this have on the earth’s inhabitants? Get solution

12qr. Get solution

13qr. (a) On the AQI scale, when is a pollutant considered unhealthful? (b) On the AQI scale, how would air be described if it had an AQI value of 250 for ozone? (c) What would be the general health effects with an AQI value of 250 for ozone? What precautions should a person take with this value? Get solution

14qr. Why is a light wind, rather than a strong wind, more conducive to high concentrations of air pollution? Get solution

15qr. How does atmospheric stability influence the accumulation of air pollutants near the surface? Get solution

16qr. Why is it that polluted air and inversions seem to go hand in hand? Get solution

17qr. Major air pollution episodes are mainly associated with radiation inversions or subsidence inversions. Explain why. Get solution

18qr. Give several reasons why taller smokestacks are better than shorter ones at improving the air quality in their immediate area. Get solution

19qr. How does the mixing depth normally change during the course of a day? As the mixing depth changes, how does it affect the concentration of pollution near the surface? Get solution

20qr. For least-polluting conditions, what would be the best time of day for a farmer to burn agricultural debris? Explain your reasoning. Get solution

21qr. Explain why most severe episodes of air pollution are associated with slow moving or stagnant high pressure areas. Get solution

22qr. How does topography influence the concentration of pollutants in cities such as Los Angeles and Denver? In mountainous terrain? Get solution

23qr. List the factors that can lead to a major buildup of atmospheric pollution. Get solution

24qr. What is an urban heat island? Is it more strongly developed at night or during the day? Explain. Get solution

25qr. What causes the “country breeze”? Why is it usually more developed at night than during the day? Would it be more easily developed in summer or winter? Explain. Get solution

26qr. How can pollution play a role in influencing the precipitation downwind of certain large industrial complexes? Get solution

27qr. What is acid deposition? Why is acid deposition considered a serious problem in many regions of the world? How does precipitation become acidic? Get solution
