When the solar terms in the northern hemisphere are vernal equinox, the midday sun height difference between the Antarctic circle and the Tropic of Cancer is 43 degrees 08 minutes. How to calculate?
The latitude of the Antarctic circle is 66.34 south latitude, and at this time, the equatorial noon sun altitude angle is 90.
That can be calculated as the noon sun height angle of the Antarctic circle = 90-66.34 = 23.26.
The tropic of cancer is 23.26, and the noon sun height angle is 90-23.26 = 66.34.
Then the difference between the two places is 66.34-23.26=43.08.
