Answer to Question 1

Answer: The period of daylight at Winnipeg is over two hours longer and this compensates for the lower midday solar angle.

Answer to Question 2

Answer: On June 21-22, the Northern Hemisphere has its maximum tilt toward the Sun (the summer solstice for that hemisphere). The Northern Hemisphere will then have a stronger orientation toward the Sun than will the Southern Hemisphere. The opposite situation exists on December 21-22 .In between these dates, on March 21-22 and September 21-22, are the equinoxes, in which neither hemisphere has a stronger orientation toward the Sun.
