Question
GEOG 104 Table 2 shows December and June average net radiation for 4 cities around the world. following 3 questions based on the information in Table 2. Answer the Table 2. City Miami, Florida Dakar, Senegal Santo Domingo, Dominican Republic London, England December Solar Angle June Solar Angle 41 49 48 15 85 71 85 62 at a higher latitude (farther from arbondale? How Based on December and June solar angles, is London, England the equator) than Carbondale, or a lower latitude (closer to the equator) than C do you know this? (3 pts.) 5. 6. Dakar is located at approximately 15°N latitude, while Santo Domingo is at approximately 19%N latitude. This means that Dakar is 4° closer to the equator than Santo Domingo. Explain why the June solar angle in Santo Domingo is higher than in Dakar. (4 pts.) 7. Which of these four cities will have the largest March solar angle and why? (2 pts.)Explanation / Answer
Answer 1: We know that the equator is the only place where seasonal variations in sun angle are very less and the sun angle is always very high no matter whether we are talking about June or December. Therefore any place near to the equator(Carbondale) show high sun angle and little difference in sun angle of June and December, however, a place like England which is far away from equator show huge sun angle variation in the season of June and December.
Answer 2: In June the solar rays hit at 90 degrees to the latitude of 23.5 because of earth axial tilt of 23.5. As we move away from the 23.5 N latitude the sun angle starts to decrease. Now we know Daker is closer to 23.5 N latitude so it shows high sun angle as compared to Sandigo which is far from 23.5N latitude.
Answer 3: March is the time of equinox the city which is closer to the equator will show the highest sun angle. Daker Senegal is closer to the equator so it will show the highest sun angle.
