At the poles (90° latitude), on the equinoxes and during polar night, the sun angle is always 0° or less no matter the axial tilt, while on the summer solstice, the maximum angle is equal to the tilt. Therefore, greater tilt means a higher maximum for the same minimum: more total annual surface insolation at the poles.
Midnight sun at the North Cape on the island of Magerøya in Norway. Midnight sun, also known as polar day, is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

Why does standing in the sun feel so much hotter than being in the shade? You feel cooler standing in the shade than in direct sunlight — but in reality, the shade represents the actual air ...
The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
Evaporation slows down and all that heat stays stuck to you, so you start cooking. That's why weather forecasters use a "heat index" to describe the weather because dry days really do feel cooler.
NIGHT SWEATS CAN be common—anxiety, stress, and sleep problems can cause them in healthy men. But in rare cases, they could be a sign of cancers such as lymphoma, leukemia, kidney, or thyroid ...
Earth's rotation relative to the Sun causes the 24-hour day/night cycle. A diurnal cycle (or diel cycle) is any pattern that recurs every 24 hours as a result of one full rotation of the planet Earth around its axis. [1] Earth's rotation causes surface temperature fluctuations throughout the day and night, as well as weather changes throughout ...
