All the figures asked for including 24-1 have been provided. I also think the question saying to use 24-8 needs to use 24-7 instead, but the site wont let me upload anymore images. Please answer whatever questions you are able to with the figures provided.
EXERCISE 24: Weather Variability and Climate Change Name Section EXERCISE 24 PROBLEMS-PART III The following questions are from 1905 to 2015 in three U.S. cities: Nome, Alaska: Bozeman, Montana; and Tucson, Arizona. based on Figure 24-6, a chart showing average annual temperature Generally, what has happened to average annual temperature in these three cities over the last century? 1. 2. Using the straight best-fit line as an indicater estimate the approximate-observed tempera ture change over the last century in each city, trdicate if the temperatare has increased (+) or decreased () (Note: these answers are based on simpliste assumptioas) are b Bozeman: 3. (a) Looking at the annual temperature value dots (not the 5-year moving average), Tucson: °F what is the warmest year shown on the chart for each of the cities? Nome: Bozeman:_ (b) What is the coldest year shown on the chart for each of the cities? Tucson: Bozeman Nome: Using the 5-year moving average lines for reference, in which of the cities does average annual temperature fluctuate the most from one year to the next or from one decade to the next? 4. (a) Do all of the major warm and cold periods in Nome correspond to warm and cold periods in the other two cities? (b) Although greenhouse gas concentration has increased steadily over the last century (see Figure 24-1), based on your answers for questions 3 and 4, is increased greenhouse effect 5. likely to be the only factor influencing temperature change in these cities? Why? 6. (a) Looking at the annual temperature value dots and the 5-year moving averages, deo you see any evidence of temperature changes following an 11-year sunspot cycle? (b) If not, why might the influence of the sunspot cycle not be evident on these charts? 173 Copyright 0 2017 Pearsos Edocation, Inc.Explanation / Answer
1. From the graph we can conclude that the average temperature of the three cities increased over the last century.
2. Tuscon - approximately +5 degree F.
Bozemon - approximately +4 degree F
Nome - approximately +3 degree F
3. a) The warmest year: Tuscon - 1995 ( 73deg) , Bozemon - 1990 (46 deg) , Nome- 1983 (29 deg)
b) The coldest year: Tuscon - 1910 (66 deg) , Bozemon - 1910 (40 deg) , Nome- 1920 (3 deg)
4. a) We can see that the average temperature of Nome fluctuates the most from one year to the next or from one decade to the next. The actual graph fluctuates a lot from the best fit line.
b) No. All the major cold and warm periods of Nome donot correspond to the other cities. There lies a variation in the time period and the change in temperature.
