Weather of Arabia - Every year, a part of the world witnesses an unusual natural phenomenon that can make the scenery of things in the real world appear to have been modified using Photoshop, which is the phenomenon of the absence of shadows in things at noon.

(A picture of a tree at the time of the occurrence of the phenomenon of lack of shade, we notice how the leaves and branches block the sun’s rays without any shade, so the image of the leaves and branches appears completely opposite of the true shape and size)
 

 

Tropic of Cancer and the summer solstice

The phenomenon of noon shadow occurs in parts of some Arab countries next Monday (June 21, 2021) in conjunction with the summer solstice, due to the occurrence of these areas on the Tropic of Cancer at latitude 23.5 north, which the sun perpendicular to on the summer solstice.

 

The Tropic of Cancer passes over the lands of 17 countries in the world, all of which witness the phenomenon of lack of noon shadow on the summer solstice, and among the Arab countries in which the Tropic of Cancer passes over their territories are: Algeria - Western Sahara - Libya - Mauritania - Egypt - Saudi Arabia - UAE - Oman

Other areas experience a lack of noon shadows at different times of the year

On the two equinoxes, which occur around March 20 (vernal equinox) and September 20 (autumn equinox), sunlight is directly above the equator so that it strikes the Earth at a 90-degree angle. This causes towns along the equator to experience no noon shadow on equinoxes.

Direct rays from the sun gradually shift north in the months leading up to the northern hemisphere summer solstice in June, when the sun is perpendicular to the Tropic of Cancer in the northern hemisphere.

 

Then, direct rays from the sun turn south each day until the day of the winter solstice in December, when the sun's rays perpendicular to the Tropic of Capricorn located south of the equator.

Because of this back-and-forth motion, all regions between the Tropic of Capricorn and the Tropic of Cancer experience perpendicular sunlight twice a year.
