Lab 3 JurjevichGEOG 101PHYSICAL GEOGRAPHY: Weather and ClimateSpring 2009Name____________________________1. As pointed out in lecture, the most common situation regarding temperature and elevation is when temperature decreases with altitude. What is this called and what is the average value utilized to express this rate?2. Aside from the ‘normal’ situation in Question #1 (where temperatures decrease with an increase in altitude), what are the other two situations that can occur with respect to temperature and altitude?3. You have been provided with information that shows that the temperature at sea level in San Diego, CA is 22°C. You are interested in determining the temperature for the mountains East of San Diego for the following elevations: 1KM, 1.5KM, 2KM, and 3KM. Assuming the average environmental lapse rate, calculate the temperatures for the above altitudes.4. On the following graph, calculate and plot the normal ELR for each altitude listed on the Y-axis of the graph and then connect the points. The lapse rate should provide you with an average temperature under ideal conditions. Start at 18°C and then calculate the ELR by plotting the rest of the points.After completing the first section, you determine that you want to obtain a more realistic ELR. Plot the points given below and connect them with a smooth line. Why do the ELR’s differ?Lab 3 JurjevichTemperature (Celsius)10°C 5°C-9°C-20°C -24°C -30°C-42°CAltitudeSeaLevel 800 1600 3000 4500 6800 1050011,000 10,000 9,000 8,000 7,000 6,000 5,000 4,000 3,000 2,000 1,000 0 -50 -40 -30 -20 -10 0 10 20 30 405. Calculate the ELR based on the following information:a. 4°C/1,000 meters = __________/1,000 metersb. 11°C/11,000 meters = __________/1,000 metersc. 9°C/1,500 meters = __________/1,000 metersd. 24°C/20,000 meters = __________/1,000 meterse. 13°C/3,000 meters =` __________/1,000 meters6. It is a hot Summer day in the Tucson basin and you attempt to beat the heat by driving up to Mt. Lemmon. Assuming that Tucson is at sea level, you notice that the temperature is 34°C and you make the following temperature observations at various altitudes:1,000 meters 30°C2,000 meters 28°C3,000 meters 26°C4,000 meters 28°C4,500 meters 29°C5,000 meters 30°CLab 3 JurjevichPlot these temperatures on an informal graph and calculate the ELR for thisexample. Under normal circumstances, would you expect this type of temperature situation and how would you classify this type of relationship?7. What are the 5 main factors that influence air temperature and briefly explain how each factor relates to air temperature?8. Evaporative coolers or sweating are good examples of _________________ transfer.9. Holding a cold rock next to a warm rock and measuring the transfer of heat is a good example of ______________.10. The warming of moist air by the sun will eventually force warm air to rise creating thunderstorms in the late afternoon. This type of situation would be classified as _______________-based thunderstorms.11. Differentiate between the terms transpiration and evapotranspiration.12. Explain what is meant by the “cyclical nature” of the urban heat island phenomenon.13. What are aerosols and why are they important?Lab 3 Jurjevich14. What is a temperature inversion and what major West coast U.S. city would you find temperature inversions to be fairly common? What is often the weather result from temperature inversions?15. What are isotherms?16. Specifically, why does a body of water (marine climate) affect the temperature of a place? How does it affect temperatures in the Summer? Winter?17. What are the two reasons we talked about in class that contribute to cooler temperatures at higher elevations?18. Differentiate between Latent and Sensible heat.19. Briefly explain how human activity can impact temperature based on thefactors that we discussed in
