How do solstice's and equinox's affect solar energy reaching the Earth's surface?
1 Answer
The angle of incidence of radiation is latitude at equinoxes and latitude
Explanation:
The angle of incidence of solar rays is their inclination to the vertical
(radius from the center of the Earth to the place), at the location.
At an equinox instant (about 21st March (vernal equinox) and 23rd
September (autumnal equinox)), the angle of incidence (
solar rays is exactly the latitude
At summer solstice (about June 21), it is '
northern latitudes, and '
It is vice versa , on winter solstice (around December 21).
This oscillatory variation '
with period 1 year, affects quantitatively the reception of solar
energy, everywhere.
