Geography solar energy & seasons 10/15/2013 8:19:00 am. Solar constant = amount of energy arriving at the outer edge of our atmosphere. What controls amount of e reaching the atmosphere. Atmospheric filtering = energy filter, filters & reduces the amount to energy so the solar constant is reduced greatly. Earth revolves around sun but rotates on its axis controls geometric relationships. Sub solar point = position on earth where sun is directly over head 90 degrees on horizon. Never gets to waterloo, 23. 5 degrees south to 23. 5 degrees north then back down to 23. 5 degrees south. 23. 5 is the angle of the axis of rotation. December solstice, the north pole has 24 hour darkness and the south pole has 24 hour light. Summer solstice, winter solstice and two equinox positions (fall & spring equinox are identical) Circle of illumination is the same for the 2 equinoxes cuts right through the middle.
