Part 1:

1. Using the graph in Figure 6.1, plot the standard temperature values given in Table 61 (the sea level value has been done for you). After you plot the data points, connect them with a line graph to complete the profile. Label the layers of the atmosphere and the transition areas at the top of each layer.

2. Briefly explain what physical properties produce a temperature decrease with altitude in the troposphere (at the normal lapse rate).

3 Why do temperatures increase throughout most of the stratosphere? Specifically discuss the process that produces this warming effect

4. After consulting the appropriate sections of a physical geography textbook, briefly describe the predicament relative to stratospheric ozone: identification and history of the problem, causes, current actions being taken, and present status

Part 2

1. Using the temperature graphs provided in Figure 6.2 plot the data from Table 6.2 for these two cities. Use a smooth curved line graph, to portray the temperature data Calculate the mean (average) annual temperature and the temperature range (difference between the highest and lowest) for each city. Fill in the other information asked for on the climograph from information given in the table.

Part 3

1. Using the data given in Table 63 plot the temperatures for these two cities and portray with a smooth curved line graph on the temperature graph in Figure 63. Fill in the other information asked for from data given in the table.

Part 4

1. Why are the temperatures at La Paz more moderate (tending toward average, i.e., less extreme) in every month and so consistent overall as compared to Concepcion?

2. Recall that the normal lapse rate of temperature change with altitude is 6.4C°/1000 m or 33F°/1000 Calculate the difference in altitude between La Paz and Concepcion, and compare the difference in their mean (average) annual temperatures. Is the difference between the mean annual temperatures for these two cities higher, lower, or the same as that produced by calculating average normal lapse rate conditions? (Show your work)

3. The annual march of the seasons and the passage of the subsolar point between the tropics of Cancer and Capricorn affect these stations. Can you detect from your temperature graphs these seasonal effects? Explain_

Part 5

1. Compare and contrast the marine temperature regime of Vancouver with the continental regime of Winnipeg. What significant differences do you note?

2. How many months register average temperatures below freezing in Winnipeg? How many months average below freezing in Vancouver?
Explain.

Part 6

1. How does wind enhanre the loss of heat from exposed satin?

2. Describe the difference between a cotton (loose-weave) jacket and a nylon windbreaker (tight-weave) jacket relative to the wind-chill concept. Which prevents the wind access to your skin more effectively?

3. Use the wind-chill chart in Figure 6.S to determine the wind-chill temperature for each of the following examples:
(°F)

a) Wind speed: 24 lauph, air temperature: -34°C = temp-
b) Wind speed: 48 larph, air temperature: -7°C = wind-chill temp.
c) Wind speed: 8 kmph, air temperature: +4°C = temp.
d) Wind speed: 56 lonph, air temperature: -23°C = wind-chill temp.

4. Competitive downhill sad racers are subjected to severe wind chill, as are average skiers and snowboarders to a lesser degree. Assuming a downhill racer is going 80 kmph (50 mph), which is coasting on some runs, and the air temperature is -18°C (0°F), what is the wind chill they are feeling on any =posed slcih?

What is their time to experience frostbite given these conditions? . In televised coverage, what kind of outfits do these racers wear for protection?
