Daily Temperatures and the Effect of Cloud Cover The questions below refer to the daily temperature graph in Figure 14.10, which is for a midatitude city on a clear day in carty summer 1. At what time does the coolest temperature occur? 2. At what time does the warmest temperature occur? 3. What is the daily temperature range (difflerence between maximum and minimum temperatures for the dayj? Daly temperature rangr 4 What is the daly mean temperature (average of the maxámum and minimum temperatures)? Diy mean temperature TUTORIAL ● SnartFigure 14.10 Typical daly teprature graph for city during the summer ธ.wiy des the coolest temperatre of the day ocar about sunrise? 6. How would cloud cover inlfluence the daily maximum temperature7 Explain your answer. 7. How would cloud cover influence the daily minimum temperature? Explain your answer. 0, sketch and label a line that represents a daily temperature graph for a typical cloudy day &. On Figure 14.10 Global Temperature Patterns 14.6 Contrast the global pattern of surface air temperatures for January and July. The primary reason for global variations in surface temperatures is the unequal distribution Among the most important secondary faciors affecting the global pattern of temperature are Pof solar radiation over Earth due to seasonal changes in Sun angle and lengh of daylight ACTIVITY 14.6 Global Temperature Patterns The following questions refer to Figure 14.11. The lines on the maps, called isotherms, connect places of equal surface temperatures 1. Is the general trend of the isotherms on the maps north-south or east-west? continued 242 Applications and Investigations in Earth Scenee Actvsty 14.6 continsed quator ANUARY 701 60F Figure 1 14.11 World distrbution of mean surface temperatures (F) for January and July. 243 Exercise Fourteen/Heating the Atmosphere 2. In general, how do surface temperatures vary from the equator toward the poles? What is the likely cause of this variation? a. Do the warmest temperatures occur over continents or over oceans? Do the coldest temperatures occur over continents or over oceans Warmest global temperatures occur over Coldest global temperatures occur over 4.Calculate the annual temperature range along the coast of Norway (Point A) and in Siberia at a location having the same latitude (Point B). Coastal Norway (Point A) Siberia (Point B) 5. Explain the wide annual range of temperatures in Siberia. 6. Why is the annual temperature range smaller along the coast of Norway than at the same latitude in Siberia? 7. Compare the average monthly temperatures for January and July for Puerto Ayacucho, Venezuela, marked as Point C on both maps. Explain why temperatures are relatively uniform throughout the year in tropical locations like Puerto Ayacucho.
