Question

Complete the table below by reading Figure 2-11 and noting the approximate number of daylight hours for each date and locations. Which latitude experienced the greater seasonal change in daylight hours? Daylight hours increase or decrease incrementally from one day to the next. During what time(s) of the year is the daylight hour change greatest? When is it smallest? Figures 2-12 and 2-13 can be used to calculate the solar elevation angle and day length at two latitudes (30 degree N and 60 degree N) for the solstices and equinoxes. The circles in these graphs show solar elevation angle, from 0 degree on the outside to 90 degree in the center. The angle labels on the outside of the outer circle measure the azimuth angle relative to north (i.e., 90 degree is east, 180 degree is south etc.) Each black curve shows the course of the sun during an individual da. For example Figure 2-12 shows that on the equinoxes at 30 degree N the sun rises directly in the east(90 degree) sets directly m the west (270 degree), and reaches its peak sun angle (60 degree) at solar noon. Describe the seasonal difference m the direction in which the sun rises and sets at 30 degree N. How does it differ at 60 degree N?

Explanation / Answer

12) june solstice 30N- 14 day light hours, 60N - 18 day light hours

equinox 30N - 12 day light hours, 60 N - 12 day light hours

december solstice: 30N 10 day light hours, 60N - 6 day light hours

13) 60N experienced greatest seasonal change

14) during june solstice dayligh hours increased to heighest and during december solstice( winter solstice )day light hours are minimum
