At 5° N latitude there are two peaks of incident solar radiation (that is, solar radiation striking Earth’s surface) during the year. Why does this location differ from other latitudes that have only one peak?
The reason why the
Answer to Problem 1E
Every latitude to the north of
Explanation of Solution
The region of the Earth receiving direct insolation from the Sun fluctuates seasonally during a year owing to the axial tilt, rotation, and revolution of the Earth. The daylight hours will be more in the region that is inclined more toward the Sun.
On June 21st, the day of June Solstice or Summer Solstice, the Sun will be directly above the Tropic of Cancer (
On December 22nd, the day of December Solstice or Winter Solstice, the Sun will be directly above the Tropic of Capricorn (
Unlike these latitudes, the Sun would be above the
